Improved Process for Injection Molding of Thin-wall Parts

SpecialChem / Dec 17, 2012

As plastic freezes in the mold cavity, conventional high variable pressure injection molding machines increase injection pressure (to maintain a substantially constant volumetric flow rate due to the smaller cross-sectional flow area). Increasing the pressure, however, has both cost and performance downsides. As the pressure required to mold the component increases, the molding equipment must be s
