Microcellular Molding Takes Off | Plastics Technology Processing BenefitsMolders Tool UpLow-Pressure AdvantageProcess DetailsTooling AdjustmentsResin Research NeededAddition of the supercritical gas can lower melt viscosity by as much as 60%, pare process temperatures by up to 140° F, decrease molding pressures by 30-50%, and cut clamp-tonnage requirements by up to 75%. Lower clamp force means lower energy costs and enables larger parts to be molded on smaller presses. It could also allow greater cavitation, as well as use of aluminum molds. In addition, MuCell molders can completely eliminate hold pressure and hold time, and reduce overall cycle times by 20%, says Trexel president and CEO David Bernstein. Some molders are turning to MuCell for the processing benefits, even when lightweighting is not a goal, Bernstein says. Some are using MuCell mainly to lower the viscosity of a hard-to-process material, which not only aids mold filling but also reduces stresses and orientation. MuCell foaming can also be a solution to molding problems such as shrinkage or warpage. “We’ve seen that 2-3% addition of supercritical gas to a part can solve 99% of...
