Trexel holds MuCell workshop

The push for lighter cars is prompting the North American auto industry to take a closer look at microcellular foaming in injection molded parts, but to get the most out of those parts, molders and carmakers alike need to plan for using the process from the start. Planning for the right expansion rates, cooling needs, wall thicknesses, gating and venting requirements will mean improved weight and reduced cycle times, said Levi Kishbaugh, vice president of engineering for Trexel Inc. during a one-day workshop on using Trexel’s MuCell process in Warren Dec. 6.
