Plastic Engineering & Technical Services, Inc. (P.E.T.S.), Auburn Hills, Mich., has introduced the PHRS family of hot-runner temperature controllers, said to “provide outstanding performance at price levels far below any competitive offerings.”

DME Co., Madison Heights, Mich., has formed a strategic alliance with Plastic Engineering & Technical Services, Inc. (P.E.T.S.), Auburn Hills, Mich.

Electrically driven valve pins, a low-cost alternative to valve-gating, mold-mounted temperature controllers, and new components for fast color changes are some of a host of new components and systems unveiled at the giant NPE 2006 show in Chicago this past June. (Some brand-new introductions since the show are also included in this report.) The news includes runnerless products aimed at everything from micromolding to shot weights up to 17.4 lb.

Thermal and mechanical testers, color and appearance sensors, vision inspection devices and CMMs—the NPE had them all in more compact, economical, and easy-to-use models.

A new hot-runner temperature controller was introduced at NPE in Chicago by Plastic Engineering & Technical Services (P.E.T.S.), Auburn Hills, Mich.

A new hot-runner valve-gate system with electric pin positioning allows for pin movements as small as 0.001 in. and up to 1 in.

A new electromagnetically actuated valve-gate cylinder reportedly delivers 110 times more accurate position control than hydraulic or pneumatic operation.

Ultimate Control for the Toughest Molding Jobs

From complete hot halves to individual nozzles, a host of new products promise smaller gate vestiges, less maintenance, better temperature control, and lower cost.
