DME shows improvements in mold components

April 25, 2012

DME Co. introduced several hot runner systems, valve gates, slides and other mold components at NPE2012.

DME’s unitized drop-in valve gate hot runner systems is designed for customers who don’t need a full hot half with plates, but still want simple setup. Everything is plumbed, assembled, pre-heated and tested before shipping. The valve gate reduces labor in sequential filling and family-mold applications. It comes in front- or rear-loaded nozzle heater options and in “A” dimensions ranging from 52 millimeters to 500 mm.

“We’re expanding our product lines to accommodate mold makers’ and designer’ needs to cut costs and save time,” said Craig Kovacic, hot runner business manager.

The new Zenith valve gate hot runner system maintains a perfectly flat thermal profile. DME said the Zenith provides better heat profiles in the nozzle and tip—areas where uniform heat prevents drooling or stringing. It uses standard DME Flex manifold heaters.

DME also launched a 16-zone hydraulic valve gate sequencer, delivering responsive control of more valve gates and faster response than typical valve gate controllers, with reduced electrical use.

A new indexable mold date insert allows molders to unscrew the date stamp from the parting line of the mold, while the mold remains in the press, instead of having to knock it out via a through-hole build into the mold. Eliminating the through-hole also increases the available options for location of the date stamp, so molders can place the stamp where it makes the most sense on the part, according to DME.

A line of standard slides are available for immediate shipping in a large range of sizes. That can cut costs in half by reducing design time and tooling costs.

“As part designers strive to create more complex features in fewer steps, they need high-quality, advanced mold components to help them maintain tighter tolerance,” said John Harding, manager of global sourcing.

DME’s Vortex core pins and plugs are a cost-effective, time-saving method of removing gas from a mold cavity during the molding process.

And a new digital scale control system helps remove hard scale that builds up in cooling systems for injection molding.
