Customize In-House Pattern Making & Tool Development Based on your Design Specifications

With highly qualified 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 mid-1980’s when 3D printers came into production, General Foundry has continuously integrated 3D printed patterns into our production design options. As each new program/project comes to us, 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.


Pattern Making & Tool Making Options

Most production tooling that is purchased from General Foundry is guaranteed for the product’s life, as long as there are no design changes. Below is a description of production tooling for each process.

Green Sand:

Production green sand tooling is manufactured via machined positive polyurethane patterns that are mounted to an aluminum plate. Our proprietary blend of sand, water, and clay is ideal for industry-leading sand casting tolerances and surface finish.

No Bake Sand:

No bake sand tools are manufactured from machined positive polyurethane patterns that are embedded in split-out cope and drag wood tooling. This process provides good dimensional tolerances and control.

Rubber Plaster Mold:

Rubber plaster mold tooling is created when rubber is poured against master negatives; the plaster is subsequently poured against those rubber positive tools. Plaster castings provide thinner walls and finer surface finish for crisper features.

Permanent Mold:

Permanent mold tooling can be machined H-13 steel or cast-iron negative molds. Permanent mold castings are usually for high volume production.

Investment Casting:

Investment cast tooling utilizes machined 6061 die (negative) to inject wax, creating wax positive patterns. Wax patterns can also be created from 3D printing.
