M.R. Mold & Engineering Co., Brea, Calif., has introduced a larger model of its “stuffer box” for prototyping, mold tryout, micromolding, and short runs of liquid silicone rubber (LSR). It’s designed to allow processing small amounts of material without waste. The user hand-mixes the LSR A and B components and loads the premix into the pneumatic stuffer, which screws onto the barrel. The original model has a 1-lb capacity; the new version holds 3 lb.

It’s not just for successful mold filling and cooling. Simulation can help predict and overcome cosmetic defects in molded parts.
