Rainier Cast Parts began producing aluminum and zinc base alloy sand castings in Enumclaw, WA in early 1996. Originally serving only local businesses, our customer base has expanded nationwide.

In October of 2003 we moved our entire operation to new facilities in Shelton, WA. We're now located in the Port of Shelton's industrial park. Along with our move, we've added the capability of producing copper base alloys.

Serving the commercial, aerospace and military markets, we produce quality sand castings in most aluminum, copper and zinc base alloys. Although we are a relatively young company, our personnel have many years experience serving these market segments. This expertise is available to assist you in designing castings to meet your specific needs.
