Protocast JLC is a lost wax investment casting foundry and CNC machine shop with its primary locations being in Los Angeles, California, with a new facility opening up in Carson City, Nevada in late 2018. Protocast JLC has been pouring steel and aluminum investment castings since 1966, serving the Aerospace, Defense, Medical, Energy, Communication markets, and many others.

Protocast JLC’s investment casting foundry was founded by John List in May of 1966, primarily pouring aluminum prototype investment castings using the solid mold flask process. Eventually, the company would utilize both the solid mold and ceramic shell processes to pour both prototype and production aluminum, steel, and copper-based investment castings, all the while offering a turnkey solution through the use of its fully-equipped machine and assembly shop. Today, Protocast JLC is still a family-run business with a knowledgeable and reliable workforce to help guide the company for years to come.
