History of Mason Industries, Inc.

Formerly known as General Pattern, Mason Industries is a progressive manufacturing operation that has been building quality tooling for our customers since 1976. Under new management since 1994, the company has grown into a leading producer of mold bases, pressure boxes and trim tooling for the plastic thermoforming industry. Whether your need is for cost effective stock tooling or large custom designed, high volume production tooling, Mason Industries is your answer to your tooling needs. While plastic thermoforming tooling is our largest product offering, we also offer tooling solutions for foundry patterns, quick turnaround prototype molds, as well as tool maintenance and repair.
