Description
A. L. Johnson Company, founded in 1954, is a manufacturing/foundry facility which produces precision aluminum and zinc castings using the Rubber/Plaster Mold (RPM) process, including complete machining and finishing operations.
A.L. Johnson, a pottery industry worker, developed the Rubber Plaster Mold process in 1954 while making molds for slip casting, a method used to produce pottery. After leasing a building to Winslow Manufacturing, a machine shop that produced nut plate drills (for aerospace applications), Johnson was contacted by one of the Winslow employees on how to cast the drills instead of machine them. Johnson then consolidated several plaster casting processes from other firms and partnered with a gypsum company to develop an aerating plaster that could be used as a mold material.
