Milliken's technology is said to boost HDPE barrier properties by 20% to 60%. This, together with SACMI's CBF technology, which reportedly produces consistent bottle walls without thin spots, is said to allow for HDPE pharma-bottle weight reduction of up to 28%. CBF main- tains bottle weight within ±0.1 g, according to SACMI. The system also incorporates eight cameras for inline QC checks of bottle dimensions, wall thickness and presence of contaminants. As we reported in the NPE Show Daily, Wilmington Machinery (wilm- was talking at NPE about several new machinery concepts. In rotary wheel machines for packaging, Wilmington has an idea that increases the machine's efficiency—the percentage of time that each mold is actually forming parts—from 65% to 80%. Russ LaBelle, company founder and pres- ident, calls it a "radical improve- ment" in dry-cycle time that will result in more bph per mold. At the show, he was also talking about foam blow molding for bottles and industrial parts. Potential applications include large (40-gal) industrial containers and automotive parts such as tanks for fluids other than fuel. LaBelle is considering foam-core and other multi-layer structures that could be produced on wheel or reciprocating-screw machines. He has a patent on a machine with three reciprocating screws that could make parts from 1 to 100 lb. Accumulator heads is another possible alternative. As reported in our April preview, Trexel, Inc. ( presented its new MuCell P-Series nitrogen dosing unit for microcellular foaming of thin-wall products such as packaging. At the show, company sources noted that this technology can also be used for injection-blow molding. What's more, Trexel has modified the design of its B-Series dosing unit for industrial extru- sion blow molding. It now can be used for both conventional 2D blow molding and 3D suction- blow molding. Also new is the ability to use the MuCell process with a standard screw, elimi- nating the need for a restriction to keep the gas from blowing back upstream, because very little gas is required for blow molding. HDPE pharma bottles are made up to 28% lighter with a combination of SACMI's Compression Blow Forming (CBF) process and Milliken's barrier-enhancing UltraGuard additive technology. @plastechmag 45 Plastics Technology Primar y Processing
