Lightweighting injection molded parts is the aim of a new Thin Recess Injection Molding (TRIM) process introduced at NPE last month by Stack Teck Systems Ltd., Brampton, Ont. TRIM reportedly enables thinning the part beyond conventional thinwall approaches and can cut part weight 20% to 40%. The patent-pending technology features a special core design with raised surfaces that thin out sections or panels of the container. It is suitable for use with high-fl ow polyolefins, and yields parts featuring thin and thick panel sections in the walls and bottom of the container. Panels can be as thin as 0.011 in. and thicker wall sections may be 0.02 to 0.025 in. Strength-to-weight ratio of TRIM parts is said to be as good as, or better than, a conventional part. TRIM can be used with single-face or stack molds and also with in-mold labels. Stack Teck also rolled out its new Compact Slide Action Closure Molds (CSAM) for 1881-style Beverage closures. Stack Teck will also highlight the innovative conformal cooling technology it licensed from RiTemp Technologies of Australia. Its technology, exhibited at the last NPE, uses large cooling chambers machined out of the core and cavity sides of the mold instead of conventional cooling channels. Stack Teck also discussed its new in-house injection molding system dedicated to prototyping and testing inmold label (IML) projects. In addition, the company now has a working relationship with Universal Closures in England, which allows it to produce cap molds for many standard bottle finishes, including tamper-evident caps (28-mm PCO, 1881 CSD, caps for flat beverages), Hinged Molded Closed (HMC) designs, and Flex Spring Hinge caps.
