Comparison testing of batch weigh blenders is becoming a more common practice for injection molders, large and small.
Two new families of “enhanced” hexene-copolymer LLDPE resins for blown film are said to offer excellent impact resistance and outstanding hot-tack and heat-seal properties. One resin family reportedly can replace high-end octene LLDPE while the other is said to equal or surpass the performance of VLDPE or metallocene LLDPE (mLLDPE).
Exactly two years ago, I discussed here some surprising statistics in Contributions of Plastics to the U.S. Economy 1997, a report from the Society of the Plastics Industry in Washington, D.C.
The huge triennial plastics exhibition in June showcased new developments in product inspection and lab instruments for testing mechanical properties, melt rheology, weatherability, color, and appearance.
New twist in foam injection molding is revolutionizing the way molders think about lightweighting parts. A microcellular foaming process, called MuCell, reverses the longstanding view that foam molding is limited to large, thick parts. Now it is possible to apply lightweighting to thin walls (0.5-mm) and small parts with critical dimensions.
