TECHNOLOGY FOR BLOW MOLDING CLASS “A” EXTERIOR BODY PANELS 880359

A new blow molding process has been developed which yields Class “A” paintable surfaces on BEXLOY® exterior body panels directly out of the mold.
The process is the result of three years of research and involves a thermocycling technique which maintains the surface of the part at a temperature above the plastic flow point. This enables the material to exactly replicate the mold surface thus eliminating surface defects such as die lines, pits, and waviness. This technology offers reduced finishing costs and greater design freedom for the use of BEXLOY Thermoplastic Resins in large Class “A” exterior body panels.
