Mold Components & Systems

Durex Industries, a designer and manufacturer of heaters, temperature sensors, and controls, announced an expansion of its custom cartridge heater capabilities with the introduction of its new advanced Magnum family of cartridge heaters.

By threading the nozzles directly into the hot runner manifold, a new hot runner nozzle offers a leak-proof design without critical stack-up dimensions that must be maintained.  The 09E nozzle, for use with Synventive Molding Solutions' line of 'Plug 'n Play' unitized hot runner systems, has thermal- and valve-gate options, including a 9-mm internal flow bore, with 30-mm mold cut-out. Synventive says the nozzle is ideal for medium-sized part applications with maximum shot weights of 250g per nozzle.

A new line of split-sheath cartridge heaters features a groove along the outside to accommodate a needle-type thermocouple that allows more accurate sensing and control for temperature-critical processing applications, such as molding heat-sensitive resins.

The Z4912 air valve from Hasco (Lüdenscheid, Germany) has been adapted to the stringent requirements of high-speed molds following a redesign to the inner structure. With the new construction, particular focus was given to achieving a stable design and connection of the individual components to guarantee long-term functioning.

Quick-Coupler-type water jumpers from DME Molding Supplies (Madison Heights, MI) can plumb a mold for cooling using significantly less mold space, according to DME. They can either be embedded in the mold itself or run on top of the mold.

DME Molding Supplies (Madison Heights, MI) has expanded its line of MRO products to include Mini-Shut Automatic Nozzle Tips. These low-cost tips shut off the flow of plastic into a mold to prevent drooling and stringing without requiring mold decompression.

What's reported to be one of the smallest manually configurable temperature control and water distribution devices with electronic monitoring on the market has debuted from injection machine builder Engel ( Schwertberg/Austria).

At the K 2010 Show in Germany, Progressive Components, a global supplier of components for the production tooling industry, introduced an addition to its CounterView line: the CVe Monitor. It monitors more than just mold cycles completed, gathering a variety of specific data, such as cycle time over the life of the tool and cycle time over the last 25,000 cycles. It also provides the percentage of activity versus downtime, downtime date ranges, and increments where mold maintenance was performed. 



The new Multi Shot Z10440/... from Hasco Hasenclever (Lüdenscheid, Germany) has been designed specifically for side gating and is ideal for articles such as sleeves and cannula tubes. The nozzle has been conceived specifically for application with polyolefins.

Melt Design, Inc. (St. Charles, IL) a leading manufacturer of runnerless injection molding systems, has introduced an anti-drool sprue bar device specially designed for use with stack molds, The patented shut-off device puts plastic drooling problems to rest and can be installed on new sprue bars or retrofitted to fit existing, non-functional ones.
