Trexel is a plastics manufacturing company based in Wilmington, Massachusetts, that specializes in the MuCell microcellular foam technology for injection molding of thermoplastics. The process enables designers to optimize wall thickness for functionality, often delivering material and weight savings of more than 20% compared with conventional molding. By replacing the traditional pack-and-hold phase with cell growth, the method produces parts with lower residual stress, improved dimensional stability, reduced warpage, and elimination of sink marks, while relying on a physical foaming mechanism that leaves no chemical residues and allows recycling within the original polymer classification. The technology has seen broad adoption across automotive, consumer electronics, medical parts, packaging, and consumer goods. In 2026, Trexel announced a strategic alliance with Roctool at Chinaplas to integrate their processes and enhance part quality and material efficiency.
