LONDON — Cinpres Ltd., which supplies gas-assisted injection molding technology, announced Dec. 2 in England that it will market BTG plc's Scorim injection molding process worldwide. Cinpres will handle licensing for injection molding companies of both technologies. The companies will share the revenues.
Scorim, also known as multilive feed injection molding, uses two hydraulically powered pistons to control the resin melt in the mold cavity before it solidifies. Once the mold is filled, the pistons move plastic forward in the sprues, runners, gates and cavities, eliminating weld lines and voids. The two pistons also can be used to intensify packing pressure and eliminate sink marks.
Scorim stands for shear controlled orientation in injection molding.
BTG spokeswoman Mary Clark said the firm has licensed Scorim to 10 companies, including injection press maker Mitsubishi Heavy Industries Ltd. of Tokyo, GE Plastics in Pittsfield, Mass., and PEP, a conglomerate of French injection molding companies. The other seven licensees are confidential, she said.
Scorim was developed in the mid-1980s by Mike Bevis and Peter Allan at Brunel University in London. BTG funded the development work.
Cinpres, of Tamworth, England, said it has licensed its gas-assisted molding technology to more than 250 companies worldwide. Gas-assist involves partially filling a mold with plastic, then injecting gas to push the melt out against the mold walls before finally packing out the mold.
