Longer glass for MuCell

摘要

Engel(www.engelglobal.com)and Trexel(www.trexel.com)are performing mold trials using long-glass-fiber-filled material and a 120-mm screw based on a new Trexel design that minimizes damage to maintain fiber length.The screw is used with Trexel's MuCell microcellular foam process.Testing reveals a five-to six-fold decrease in part warpage,thanks to retention of fiber lengths of 12 mm and longer(Figure 1).
