New Tooling Components Designed For 'Rapid Tooling' Technology

Progressive Components has added a range of new tooling components:

  • RTI Complete standardized unit inserts and RTI cavity and core inserts

  • Heating and cooling line safety tags

  • Thousandth increment core pins

  • Ejector sleeve system components

'Rapid tooling' expansions Progressive says it has a number of new products designed to help mold builders reduce mold delivery times and take further advantage of various 'rapid tooling' technologies.

RTI Complete is a standardized unit insert that is completely machined to accept standardized cavity and core inserts. These inserts also include clearance for water lines, support pillars and all of the alignment products already featured in the standard RTIs.

A pocket is provided for the pin plate so mold makers can completely change the tool for different parts without any machining of the insert itself. The RTI Complete is priced at $1775.

The RTI cavity and core inserts are manufactured from modified H-13 or DH2F material, which allows mold makers to immediately machine cavity and core details without sending the inserts out for additional heat treatment.

DH2F is said to be easy to machine and comes in at 40 to 42 Rc from International Mold Steel with screws included. RTI cavity and core inserts are priced at $210 and $325, respectively.

If a basic insert is required for a certain application, mold makers can use the RTI S-Series insert, an economical alternative, for prototype tooling. The S-Series is designed to be compatible with common industry standard frames and is economically priced when compared to competitive inserts. Price is $295.

These inserts feature four leader pins and bushings for alignment and are finish ground. They exclude any fasteners or other holes in the A or B plates or the pin plates for easy relocation of components.

The S-Series has an even side surface instead of the 'ears' found on the clamp slot on the standard inserts. This surface allows the mold builder to easily hold the work piece for installation of water lines or locks on the side of the plates. 

7.jpgSafety tags Stamping 'in' and 'out' on the side of the mold has been common practice for years for cooling lines. But what do you use to identify the hose that connects to the mold or the hose that connects to the water source?

Progressive's color-coded identifiers are designed to mark primary and secondary circuits around the connector or extension plugs (Mold Tags), the socket connectors (Safety Tags) and the hoses (Hose Tags). In addition to coolant identification, Safety Tags keep the socket connector from backing up and disconnecting.

The extra plastic 'loop' is installed behind the sleeve after attachment to the connector or extension plug and remains connected to the hose and socket connector, unlike other methods, according to Progressive.

All three styles are available in four colors (red, blue, purple and orange). Prices range from $0.40 to $0.55 each.

8.jpgThousandth increment core pins TI Pins are manufactured from high-speed steel and are available in 0.001-in. increments from 0.60 to 0.320 in. dia in lengths of 2.5 in. More than 260 sizes are available.

The pins are designed to help mold builders eliminate the time-consuming finishing work associated with fractionally sized core pins. The TI Pins are said to have one additional time-saving feature: they eliminate the need for finish-grinding the heads from +0.015 in. tolerance down to the common counterbore tolerances. The TI Pins come with the standard head thickness tolerance of +0.000/-0.002.

The pins are sold bagged in quantities of 10 and are batch identified. Pricing (ranging between $42.50 and $57) is said to be comparable to standard core pins.

9.jpgEjector sleeve components The company has three new components that are designed to further standardize mold ejection: Thin Wall Sleeves, Sleeve Extensions and Core Pin Retainers.

Thin Wall Sleeves are designed for thinner plastic wall sections. These sleeves have a 0.03-in. wall thickness, so mold makers don't have to purchase a custom ejector sleeve or machine an extra step in a standard sleeve.

These sleeves come with inner diameters of 3/32 to 3/8 in. in two standard lengths: 4 or 6 in. The bearing lengths are similar to those of standard sleeves, with 2 in. of bearing and a long tapered lead-in from the end of the sleeve.

Units are made from A-2, providing a cross-section that steps out to a wider shoulder and head diameter. They are treated with Nickolon on the inner and outer diameters to provide wear resistance and lubricity. Prices range from $75 to $85.

Another product designed to eliminate special orders is the Sleeve Extension. Many times, a larger mold will call for sleeves longer than standard. By using the Sleeve Extension, catalog standard and Progressive's Thin Wall Sleeves gain an extra 3 in. of height while maintaining industry standard counterbores in the pin plates.

Sleeve Extensions can be easily installed in the pin plates first, and the ejector sleeve simply slides into the 'T' slot on the Extension, with no additional machining. They are manufactured from 1215 steel and etched for identification. Price is $20.

In addition to these standard products, the company has developed what it says is a simple and cost-effective method to retain the center core pin when used in ejector sleeve applications. These units are priced at $4.25 each.

Core Pin Retainers use a standard thread size, similar to a set screw. But, unlike a set screw, a head enables the retainer to bottom out rather than thread into the core pin head. This allows the pin to float slightly for optimum pin-to-sleeve performance and eliminates the need for extra machining or space-obtrusive plates.
