Sometimes customers just want to see how something works — and that's the approach Westminster Tool Inc. took in hosting a dovetail collapsible core demonstration day this month at its Plainfield plant.
The mold maker partnered with several other firms to demo a mold with a DT collapsible core supplied by Roehr Tool Corp., of Hudson, Mass. The mold ran on Westminster's 110-ton Toyo injection press making mock-up caps for a cosmetic product. More than 100 students, customers, suppliers and partners participated in the Oct. 3 event.
“What we see is that they are skeptical. They don't have the time. They don't have the money. But if you take a mold and modify it, they can see it for themselves. You remove the barriers,” said Al Hickok, technical sales manager of Roehr Tool Corp.
Waconda, Ill.-based Progressive Components International Corp. — Roehr's parent company — provided a four-cavity mold base that it had used for trade shows, according to Hickok. Mastip Inc. of Slinger, Wis., provided the hot-runner system with the new MJ-9 nozzle for high-cavitation packaging like caps and closures and medical applications.
Other members of the PCIC group of companies contributed as well, including AST Technology GmbH, Progressive Components and Tooling Docs LLC. Also providing mold components was DME Co., with its internal latch lock mechanism for controlling the mold plate opening sequence.
The aim of the demo, according to Hickok, was to show that the DT collapsible core was a viable alternative to unscrewing molds. His claim is that the DT saves costs and is simpler to run.
“It brought our cycle time down 40 percent,” said Phil Titherington, product development director at Mold-Rite Plastics, of Plattsburgh, N.Y.
Titherington said his company started working the collapsible core 12 years ago while retrofitting an old mold. It created significant cost savings so the firm went on to build two 72-cavity collapsible molds.
An enthusiast, Titherington is now working on second-generation prototypes.
