New Auxiliaries Are Modular And Easy To Use

New Auxiliaries Are Modular And Easy To Use

Motan's NPE offerings included a new press-side dryer, new control options for their Luxor drying line, three new gravimetric dosing and blending units, a new graphical user interface (GUI) for materials handling and an automated materials selection and distribution system.

Pricing information is available directly from Motan, using the Key Contact Directory on p 38.

Press-side dryer The portable Luxor 80 dryer is designed to produce 80 cu ft/min of dry air at a dew point of -40 F. Unit has twin stationary desiccant beds, alternate process and regeneration cycles and separate process and regeneration heaters. It accommodates one or two drying bins with volumes ranging between 60 and 250 lb.

The dry air heater is mounted directly to the drying bin to avoid energy loss during the transportation of dry air. Motan is targeting this unit at applications requiring low throughput rates.

The portable dryer is mounted on casters. Other features include a drying bin adapter for material take-off and a drying bin shut-off slide gate.

Dryer control options are designed for use with Motan's entire Luxor dryer line, as well as with older lines of dryers and blenders.

For larger dryers is the Luxor PLC Control, which uses commercial PLCs with touchscreen and full diagnostics for 4-hr operating windows for all dryer functions. Troubleshooting procedures, as well as fault memory can be accessed through the touchscreen. Digital screen captures are available on request.

For smaller dryers, the Luxor AM Controls use Motan's AM (Advanced Microprocessor) control, which is said to be very easy and simple to use. The AM controller automatically establishes drying temperatures, drying time and temperature modulations for up to 24 different materials. All the operator has to do is push the 'start' button and the AM controller takes over.

The AM comes standard with the ATN drying function, which monitors material throughput against the drying time and lowers the temperature to prevent damage during low-throughput situations. This is said to save energy and to keep the material dry until throughput increases. The ATN system is designed to then ramp temperatures up to provide modulation of process temperatures based on material use.

The ATN function is a retrofittable option on the Luxor PLC controller.

Four-material gravimetric blender meters and blends up to 150 kg/hr (~330 lb/hr) with accuracy rated at 0.1%, according toMotan. The unit is equipped with segmented hoppers, a weighing hopper and two weighing cells. Cylindrical valves are used for dosing.

The Gravicolor 100 can be installed directly on injection molding machines and extruders, or it can be used as a central blending station. All hardware in contact with resin is stainless steel and a large site glass is included.

PLCs constantly check the actual metered and weighed amounts against preset values. An interface to a printer and/or central control is available.

Other specifications: dosing range per component, 5 to 100%, dosing range per additive, 0.8 to 10% and hopper capacity (component or additive), 18 lb. 

Six-material gravimetric blender is designed for both injection molding and extrusion processes. It has a throughput of 300 kg/hr (~660 lb/hr) and, like the Gravicolor 100, it is said to be capable of blending additives to within ±0.1% accuracy.

The stainless steel unit has a swing-slide gate and the mixing chamber is set on a slight bias to ensure complete emptying. The inlet is flared to minimize the change of spillage. A window surrounds the blender.

PLCs include a full-message display for ease of use and viewing of all parameters. The control panel can be removed and operated from another position.

Other specifications: dosing range per component, 5 to 100%, dosing range per additive, 0.8 to 10%, hopper capacity (component), 50 lb and hopper capacity (additive), 20 lb. 

Compact blender can be mounted on the feed throat of an injection molding machine and comes with the option of two dosing stations, each with a maximum capacity of 44 lb/hr.

Three versions are available with dosing ranges as follows: 0.2 to 3.3 lb/hr, 1.1 to 16.5 lb/hr and 3.3 to 44 lb/hr. Total throughput is 260 lb/hr. Additive hopper capacity is 12 lb.

The MiniColor is also equipped with a brushless motor, which reduces maintenance.

The unit also has a sight glass that spans the entire length of the hopper. A small encased compressed air loader, the MiniColor LV, is an option that can be attached by changing the hopper lid.

Two types of control are available and dosing can be either continuous for extrusion or during screw-back times for injection. 

Graphical user interface (GUI), calledLinkNet, is said to simplify and centrally control the monitoring and verifying functions of conveying, drying and blending systems. The GUI checks the input from each plant shift's database, which logssetpoints, feedback, alarms and other event data and does not accept invalid input.

Designed for Windows, LinkNet uses a simple and intuitive menu-driven format. It offers multiple levels of password-protected access so various users (floor managers, machine operators and service engineers) can access the system at different levels. A 'help' link in the display menu allows users to ask questions. 

Material selection and distribution is automated withMetroLink, a modular unit that accepts as many as 16 source materials and accommodates from three to 15 machines. Rapid and contamination-free material changes are claimed because flexible material hose is not used in MetroLink's construction.

Instead, it uses an air cylinder to rotate a disk into the precise position to connect the materials to a pre-programmed destination. These stations can be configured with up to 15 standard rotating disks, allowing the unit to convey to as many as 240 connections. Material line diameter is 1-1/2 in.

The compact, vertical design is said to have minimal space requirements. Units can be stacked. Dimensions are as follows: for three to five outlets, system is 7.8 in. tall; for six to 10 outlets, 11.6 in. tall and for 11 to 15 outlets, 15.4 in. tall.

Auxiliary Equipment Maker To Debut New Dryer Technology, Feeders,Blenders And More At NPE

Controller Brings The Internet And More To Your Plastics Processing Machine

Milacron's familiar CAMAC user interface has gotten a major facelift. Demonstrated at NPE, the new Xtreem plastics processing machinery controller includes a range of 'cutting-edge' technologies, such as Internet-based OneTouch video-conferencing with Milacron's process support center.

The new controller is available on all new Milacron machines, and can be retrofit on existing Milacron and other brand name machines.

Analogous to the OnStar system used in automobiles, where the driver can access a live person to help withdirections, emergencies and the like, OneTouch brings a Milacron support person to your plant via the Internet.

"We can't 'beam' an operator out of a tight situation, but we can 'beam in' face-to-face support from a real process expert, right on the machine's control screen," says Bill Gruber, Vice President, Ferromatik Milacron North America. "OneTouch also integrates with the new electronic customer relations management (eCRM) system used by our ServTek business to speed service and repair parts." (See Industry News, p 27.)

Other new Xtreem control capabilities introduced at NPE include:

* VoicePad ­ Allows the operator to record an 'audio memo' that can be attached to a mold file, for example, even in multiple languages.

* VideoPad ­ Streaming video or still photos can be attached to another file in much the same way as the VoicePad memos. For example, part defects/features or mold set-up can be explained and demonstrated in video.

* VoiceCounselor ­ Allows recording of audio advisories, tips and troubleshooting directions. These can be selectively attached to the control's messages, faults and alarms to aid the operator through machine or process troubleshooting.

* VideoCounselor ­ Allows streaming video to be captured and attached to faults, alarms, etc. in the same way as VoiceCounselor advisories. Again, the machine owner can record voice and/or video 'tips' that are invoked for the operator when specific situations or faults arise.

* Remote diagnostics ­ Via the Internet or Ethernet, this feature allows a process expert (Milacron's or the customer's own) to look at all the operating parameters of the machine, as if standing at the control, and change the setup, if the operator consents. Additionally, real-time oscilloscope functions provide remote measurement plots of machine performance, without the expensive purchase of separate diagnostic equipment.

"The Xtreem control is the culmination of a 10-year strategy to make reliable PC-based control an industrial reality, and it represents a significant investment by Milacron to provide low-cost, flexible solutions to its customers," says Gruber.

"The computer infrastructure needed to implement these new capabilities is inherent to the Xtreem control's industrial PC platform and the Internet, both of which are universally supported and used by customers in the office. The customer can now bring low-cost 'office PC' solutions and networking to the shop floor, using the same technology and human resources already needed for the office computer network. More importantly, shop floor production systems can now be easily networked into the customer's business information systems to facilitate e-commerce, order entry and reporting. Our control can now be a portal to the Internet and the business data network, while providing dozens of new process features as well."

Introduced at NPE '97 as the first PC-based control for plastics injection molding machines, the Xtreem control is already standard on a wide range of Milacron's injection molding machines, and is available on extrusion systems as well. The operator interface on injection machine controls is 'backwardly compatible' with the earlier generation CAMAC control, so the look and feel for the operator are essentially identical, eliminating retraining issues.

The Xtreem utilizes 100% industrial PC hardware, allowing upgrades to the latest PC technology as they become available. Two versions of the Xtreem are available: ST and NT.

Both models have a 3.5-in. floppy drive, a keyboard port, Ethernet port and parallel port, allowing plastics processing machines to cable-up to the office PC network.

The higher-level NT model runs Microsoft's Windows NT operating system. The operator station PC has 64 mb RAM, a 2 gb hard drive and an uninterruptable power supply.

The NT control includes a mouse port, and it can perform essentially just like an office PC, running any third-party, Windows-compatible software for data acquisition/analysis, vision, imaging and multimedia. It has built-in Internet Explorer, allowing the molding machine to tap the resources of the Internet and e-mail.

"This commonality between shop and office systems leverages the customer's investment in software, computer support and training," Gruber says.

"The cost advantage of using a PC platform for a controller, with all the 'magic' of machine control now in software and not PLC hardware, is strongly evident even in the basic ST model," adds Gruber. "It carries as standard, software that had previously sold for nearly $20,000 as options on the previous-generation control."

Both controls have a new range of displays and capabilities for the operator/processor, too. Injection machine displays now include screw volume percent displacement, melt pressure, plots of pressure/volume/cavity pressure/screw position. Standard and configurable core sequences are both available, along with eight configurable I/Os.

The control stores the last 100 cycles of process data, which can be saved to floppy disk, printed or loaded into Excel for analysis. Process monitoring is precise, with 0.01 mm digital position feedback and 2 millisecond timer accuracy. A change log keeps track of the last 100 setpoint changes, who made them, when and the old/new values.

NT models include the additional new features of VoicePad, VideoPad, VoiceCounselor and VideoCounselor, along with third-party compatibility for Avalon Vision, Kistler Autoflow and Moldflow MPX.

Milacron's own MVT (Machine Validation Tool) diagnostics package, used to set up and test machines at the factory, is included on the NT model. It can monitor and plot up to 10,000 variables and offers configurable alarms, scaling and sampling. Performance of components or overall systems on the machine can be monitored with MVT, either at the machine or remotely over the Internet or Local Area Network, at the user's discretion.

MVT is designed to pinpointwearing components, such as sticking valves, to improve the efficiency oftroubleshooting or service calls. Italso allows recording of this data to facilitate meeting QS9000 and FDA requirements.

Digital I/O Module Enhances PID Controller

Digital I/O Module Enhances PID Controller

Watlow Anafaze has introduced a digital input/output module, the PPC-2040, as an accessory to the PPC-2000. The PPC-2000 is a multi-loop PID controller with built-in programmable logic functions for OEMs (May '00 PA, p 82). The unit is to be considered an alternative for engineers who are using individual controllers and PLC units from different vendors.

The PPC-2040 card allows users to individually configure each of the 32 I/O points as either an input or an output. Up to two inputs can read high-speed pulse signals. These options allow users to adjust the I/O balance of the module to meet the requirements of each application.

"Too often, users end up with unused I/O capacity and therefore lessen their return on investment," says Bill Kolbeck, General Manager of Watlow Anafaze. "This module was created to offer an efficient I/O module option."

New Dicer Offers Quick-Change, Low Maintenance

New Dicer Offers Quick-Change, Low Maintenance

Dicer Corp.'s WebPro 800 Dicer is designed to provide custom compounders and masterbatch producers a quick change, low maintenance dicer. The WebPRO 800 processes from 50 to 800 lb/hr of rigid or flexible material with a durometer as low as 45 Shore A. Typical materials are rigid and flexible PVC, ABS,PU, PP and nylon.

The company says that in actual dicer trials, the WebPRO 800 diced such diverse material as glass-filled polycarbonate sheet, polyester thin sheet, ionomer sheet, PTFE sheet, siding, carpet, nylon impregnated roving, paperboard and aromatic wood sheet.

Priced at $35,400 (without the motor or drive, which are customer specified), the unit is also said to be the first dicer sized and priced to allow injection molders and general extrusion houses to vertically integrate compounding in their operations.

The WebPRO 800 can also be used to dice edge trim and other scrap material, which can then be immediately reintroduced as OctaPellets without additional processing.

Throughput can be over 800 lb/hr based on a specific gravity of 1.4. Advantages of producing a web are that die back-pressure is reduced, thereby increasing extruder throughput by about 10%, and that the web eliminates die freeze off, and strand breakage therefore using less labor.

The core components of the dicer are a single-piece helical cutterhead and matching bedknife, which provide for quick changeover and easy clean up for short runs of diverse materials and frequent color changes. Dicers come with either ac or dc motors and drives that are either within a closed-loop programmable system or free standing.

Container Spin Trimming Systems Now Come With Gear Belts

Container Spin TrimmingSystems Now Come WithGear Belts

At NPE MTM showed two spin trimming systems (the 730AG Portable Spin Trimmer and the 2025HCM-ID Horizontal Spin Trimmer) that are now available with gear belt technology, which is said to provide a more efficient, positive drive system for longer belt life and reduced chance of slippage.

The 730AG Portable Spin Trimmer uses a toothed belt and gear-type pulleys to provide efficient and positive power transmission. This low-cost trimming system incorporates MTM's patented Heated Blade Technology to trim a variety of container sizes.

MTM says the 730AG can be easily moved from site to site and is ideal for smaller shops that produce shorter runs of different container sizes. The trimmer can also be installed over a conveyor system for a dedicated installation.

This trimmer is designed to accommodate containers with 1.5 to 7-in. diameters and neck sizes up to 110 mm (4.3 in.). Container heights can vary from 3 to 18 in. on standard machines. Custom adaptations are possible for off-size containers.

While container dimensions determine the maximum number of trimmed containers per minute, MTM says the 730AG reaches speeds of more than 80 containers/min. Trim speeds are controlled by a variable-speed drive system, and blade temperature is fully adjustable via proportioning control.

The 730AG Spin Trimmer incorporates a pneumatically controlled part guide to release jammed containers so operators don't have to enter the actual trim area. When the jam is cleared, the blade and dome guide can be automatically returned to their original position without adjustment.

In addition, the Trim Head can be raised and lowered independently of the frame for easier and faster container-height adjustments. Trim blade angle and depth selections can be made with micrometer-style adjustment.

The 2025HCM-ID Horizontal Spin Trimmer is designed to trim mouth-to-mouth or 'log-style' containers. Like the 730AG, this model has a toothed belt and gear-type pulleys and uses MTM's Heated Blade Technology.

The 2025HCM accommodates containers with 1.5 to 7-in. diameters with neck sizes up to 110 mm (4.3 in.). Container heights can vary from 3 to 18 in. on standard machines. It can operate at speeds of more than 380 containers/min. Temperature adjustment is via a proportioning control, and trim speeds are controlled by a variable-speed drive system.

Range Of Tooling Components Debuts At NPE

Range Of Tooling Components Debuts At NPE

D-M-E Company introduced a range of new products and services at NPE, including an internal latch lock and a variety of hot runner systems and temperature control systems.

Miniature hot runners In response to increased demand for hot runner systems with small part capabilities, D-M-E has unveiled a new, competitively priced hot runner product line for precision micromolding applications.

Designed for use in mold bases with center-to-center distances as small as 17 mm, the externally heated Stellar hot runner system is said to work well with either commodity or engineering grade resins and can be used in such applications as electrical, electronic, medical and cosmetic packaging.

Stellar nozzles feature a front-loaded design for the tips, low conductivity front seals, heaters and thermocouples. This front load capability is said to maximize uptime by enabling quick access with the mold in the press. Four interchangeable nozzle tips are available, including wear-resistant point gate, thru-hole, sprue gate and extended point gate.

Mini-tubular nozzle heaters are said to provide reliability and longevity and to reduce maintenance costs. The modular nozzle bodies are interchangeable and can be attached to a manifold using either threaded or compression connections. Standardized multi-nozzle assemblies accept threaded nozzles. Custom applications use compression-style nozzle connections.

Eight nozzle 'A' dimensions are available from 35 to 105 mm. By substituting the nozzle head, a 10 mm adjustment can be made to the nozzle 'A' dimension, increasing flexibility and cost savings. Tight cavity spacing made possible by the compact Stellar nozzle design results in cycle-time savings for even the smallest parts.

A variety of Multiple Nozzle Assemblies (MNAs) is available in standardized configurations of 2, 3, 4, 6, 8, 12 and 16 drops. MNAs are flow balanced and can be used either as stand-alone systems or underneath custom manifolds.

Stellar systems are suitable for Master Unit Die (MUD) quick-change systems. The turnkey hot half system is bolted onto the MUD frame. A secondary parting line position is used to separate the hot runner system from the 'A' plate, enabling the quick changes to take place. 

Rapid deliveries of custom ejector pins are the goal of D-M-E's new Quick Custom and Full Custom programs. The Quick Custom program includes more than 7500 options in the most frequently requested custom pins; it provides immediate pricing and shipment within five working days.

For more specific needs, or for special ejector sleeves, the Full Custom program guarantees price quoting within 24 hours (regardless of complexity, according to the company) and on-time delivery.

Custom features of the pins include, but are not limited to: steps, profiles, custom shoulders, O-ring grooves, non-standard core hardness, flats, threaded I.D. or O.D., non-standard materials, custom diameters (0.025 to 3 in.) and lengths (up to 72 in.) and over 100 surface coatings, including titanium nitriding, ion nitriding, black oxide and chromium. 

Standard hot runner systems

Available on a same-day basis, Meteor hot runner systems are designed for two- and four-drop configurations, and are suitable for both commodity and engineered resins.

The pre-designed and pre-manufactured manifolds meet the needs of users who require fast delivery. Meteor systems are said to be less expensive than custom hot runner systems, so users can quickly justify prototype projectsor applications with lower production volumes.

Three systems are available: the standard manifold, Meteor1; or in two levels of time-saving component and systems integration, Meteor2 and Meteor3.

Meteor1 is a standard, off-the-shelf manifold with a machined main flow channel. It has built-in flexibility because its nozzle locations are machined and its end plugs fitted by the customer. Meteor1 is stocked in two convenient shapes, 'in-line' and 'X' pattern, for two and four-drop applications, respectively.

Six 'in-line' sizes and four 'X' style manifolds are offered. In addition, the 'in-line' manifolds are available with two heater exit options: end and center.

The Meteor1 manifold can be integrated into a complete hot runner system. Everything needed to build a system, including nozzles, supports, nozzle seat, locating ring, thermocouples and other components are also available to ship same day. Nozzle selection can be made from a range of D-M-E standards, including 250 and 375 Series, and the Gate-Mate 4 and Mini Gate-Mate Series.

Alternatively, the Meteor manifold can be integrated into a manifold and components system by D-M-E. Called Meteor2, this option includes machining of the vertical channels and the installation of end plugs, and has a lead time of one week or less.

For those who need an integrated solution with fast delivery, D-M-E offers a complete system. Meteor3 is a turnkey system comprising D-M-E standard products, including a hot half with a Meteor manifold configured into a standard mold base and a 5-zone temperature controller.

The hot half comes assembled, wired and tested and ready to bolt onto the mold base. The standard mold base and the 5-zone temperature controller are optional. Meteor3 has 3-week delivery.

Internal latch lock D-M-E's first internal latch lock, the newDKL, is said to give moldmakers greater design flexibility and control on stripper and floating plate molds. D-M-E says the DKL Latch Lock improves on earlier design concepts by offering built-in stroke limitation and longer wear with space-saving compactness.

It comes in three basic latch sizes (28 mm, 34 mm and 45 mm) for fit with D-M-E standard mold bases. These sizes can be ordered with short- or long-range travel and each size is available in two center puller pin lengths. An optional sleeve feature can be added to provide guided ejection and ejector assembly return.

The DKL Latch Lock allows users to control stripper plates or other floating plates in various mold base designs. The product is designed to avoid water line interference and solves design problems with externally mounted plate latching devices, while requiring less space inside the mold than other internal lock designs. The compact, cylindrical DKL plate latching assembly features rectangular cams with large surface contact areas that are hardened.

Edge gate technology D-M-E has joined forces with Heisskanal Technik Schulte(HTS), a hot runner solutions manufacturer based in Lüdenscheid, Germany, to provide edge gate technology worldwide. The partnership will also focus on solutions in point gating and valve gating.

The HTS edge gate system is said to have a highly flexible design with multiple performance advantages over other edge gate products on the market:

  • Systems are both compact and flow balanced
  • Sealed edge gate tips are mounted directly into the manifolds
  • 10 mm center-to-center spacing
  • Capable of running all thermoplastics, including difficult engineering materials.
  • Fast color changes
  • Quick and easy installation
  • Leak-proof operation
  • 50% less heat transfer to the mold base and cavities with polish and chrome finish
  • Interchangeable cavity blocks
  • Fewer control zones for extremely simply operation and reduced temperature controller costs
  • Greater safety benefits through heater and thermocouple wire protection

HTS patented flow balancingtechnology is available in 2 x 4, 2 x 8 and 2 x 16 standard manifold configurations. In addition, these small manifold blocks can be mounted under bridge manifolds to achieve highercavitation molding.

HTS point gate systems offer all of the advantages of HTS edge gate systems but with direct gating into the center of the part. HTS point gate systems allow center-to-center spacing as close as 14 mm.

The HTS valve gate system is a plate actuated, pneumatic design that is designed for Master Unit Die (MUD) frames. Available in either 4- or 8-drop configurations, the HTS valve gate is a standardized, bolt-on hot half, with all electronics and pneumatics attached to the system. 

Smart temperature controls Three newly improved Smart Series temperature control modules are designed to provide simple, economical solutions for single to multi-zone mainframes.

A second generation design, the SSM-15-02 control module combines a higher degree of selectivity with a setpoint push-wheel for fast, simple setting of desired setpoint temperature, and larger, easy-to-read digital displays of temperature, percent power and faults. Both setpoint and process temperature are displayed simultaneously.

An Auto Percent Power Display shows power output while in Auto mode, plus indicates average percent power requirement on thermocouple failure. This serves as a diagnostic tool for solving hot runner system problems.

In addition, many new operational refinements and switchable options have been added to the SSM-15-02 module:

  • Improved SmartStart capability provides a more gradual rise to make the heater dry-out period more effective and extend heater life.
  • Selective Cycle delivers a high speed power output that enables accurate temperature control and longer heater life.
  • The Bumpless Transfer feature responds to thermocouple failure by automatically continuing operation at a learned percent power.
  • Boost, Idle and Power Off enhancements provide system-wide temperature adjustment, enabling alarm audio/visual output and remote alarms. These features require the use of the TAS-05-12 module and communications mainframe.
  • An AutoBoost option instantaneously opens frozen gages on start-up.
  • The Lights Out feature goes into actuation after stabilizing at setpoint. The display turns off, leaving only the green LED illuminated. When a fault occurs, the display is turned on and flashes.

The Temperature Alarm/System Control Module (TAS-05-12/11) provides economical networking of SSM-15-02/01 controls to allow system-wide temperature adjustment for multiple control zones. The TAS module also provides simple, single-zone monitoring of system performance, generating visual (LED) and audible alarms of temperature deviations or diagnostic errors.

Up to 63 zones can be controlled remotely at one time. A rotary switch enables all zones to be simultaneously changed between Normal, Idle (standby heat) and Boost/Off operation.

The Idle mode temporarily lowers all hot runner system zones to prevent material degradation and keep heaters warm enough to prevent absorption of moisture. Switching back to Normal restores all modules to their established setpoints.

The Boost feature can be used to raise the setpoint of the modules by 10, 20 or 30% to drive up nozzle zone temperatures in order to open frozen gates. The Off mode cuts power to the heater but cool down of the hot runner system can still be monitored.

And finally, the SSH-10-12 Single Zone Temperature Controller is a compact, self-contained module that makes it easy to add PID control to a hot sprue bushing or a machine nozzle.

This new module reportedly improves on the previous SSH-10-02by offering setpoint push-wheel,larger LED display for better readability of temperature, percent powerand fault displays. Operational refinements include improved SmartStart, SelectiveCycle, and Bumpless Transfer as standard features, plus several switchable options. 

Mold frame Master Unit Die Products, a D-M-E company, has a new solution for quick-change insert molding...the top-load 'E' style mold frame. The 'E' frame accepts the same size insert molds as current MUD 'H' style frames, but allows the insert molds to be lowered into the frame from above using an overhead handling system. This reportedly provides more ease and safety in the handling of heavy MUD insert molds, compared to side loading on the front and back of the molding machine.

The 'E' Frame is center sprue-injected into the center runner bar and side gated into the insert molds. An optional runner allows molds to be gated from the end, making them interchangeable with a comparable 'H' style mold frame for application flexibility. Runner shut-offs, standard on the E Frame, allow the molder to direct the flow of material to either the side gates or the optional runner system as required.

Order A Robot, Get It In Two Days

Order A Robot, Get It In Two Days

  Here's some additional information on a new product line for Direct-Line Products: robots. First mentioned in our May '00 NPE preview (p 32), these traversing robots andsprue-pickers are claimed to be ready-to-ship (2-day delivery) and easy to install. They are available for injection molding machines from 25 to 300 tons.

Key to these robots is their ease of installation. Direct-Line says installation costs usually add 10 to 20% to the cost of a robot, so why not do it yourself? The company says its 'plain-English' installation manual is comprehensive and explains all aspects of installation and start up for all three of the following types of robots Direct-Line supplies.

TA Series traversing 3-axis robots are available in four sizes to fit molding machines from 50 to 300 tons. Prices range from $11,295 to $12,695. For the higher price, you get model TA4048, which is for molding machines between 200 and 300 tons. Vertical stroke is 40 in., traverse stroke is 48 in. and payload is 8 lb. It also has a 90-deg wrist bend and controller with LCD screen.
