In high-volume injection molding, hot runner systems are the silent workhorses behind every shot. They govern how melt flows, how cavities fill, how much pressure is needed, and, ultimately, part ...

The runner system consists of three sections, the sprue, runner, and thegate. The primary task of a runner is to deliver and ...

"I'm getting hammered by my 'partner-customers,' " my client told me. "They send me the molds from someone else they've put out of business and expect me to make better parts, faster, at less cost!" ...

A new, downloadable software program is intended to help users develop the shape of injection molding runners and gates. An improved user interface requires fewer clicks and produces gating designs ...

Westfall Technik’s MHS says its patented pneumatic actuator technology represents a paradigm shift from the standard design’s need for seals and cooling.

Mold-Masters says its IRIS nozzle is very compact—the same as a normal nozzle—and is very easy to service, allowing replacement of the tip, seal, and thermocouple as in a normal hot-runner nozzle.

Cycle time is the primary cost measure of the molding process, and cooling represents about 80% of the molding cycle (see Figure 1). The thicker the part, the longer the cycle time. However, the ...

Düsseldorf, Germany — Husky Injection Molding Systems Ltd. has a continuing investment program in its hot runners business. Its senior managers outlined these investments at a K 2016 news briefing, ...
