It's all about service — General Foundry Service

Patternmaking / Toolmaking

General Foundry has had in house pattern making since 1946, allowing us to respond quickly and economically to design changes and customer iterations. With multiple patternmakers on staff, we can match the tooling needed for your program; whether it’s a long term production style tool or a short term prototype tool, we have a solution. Since the 1990’s when 3d printers came online, we have integrated 3d printed patterns, and continue to have that tool in our toolbox. As each new program/project comes, we tailor our tooling solution to match our customer’s needs. All tooling is customer owned, and stored by General Foundry to run when orders are placed.

If production tooling is purchased from us, most of it will be guaranteed for the product’s life. Below is a description of production tooling for each process.
