The Heart of Injection Molding

A custom plastic mold, often called a "tool" or "tooling," is a precision-engineered piece of equipment that contains the inverse shape of your desired plastic part. It typically consists of two main halves (the core and cavity) that precisely fit together.

During injection molding, molten plastic is injected into the mold cavity, cools, and solidifies into the final part shape. The quality of your final plastic parts is directly dependent on the precision and quality of the mold itself.

Tooling Solutions for Every Volume

We offer mold-making solutions tailored to your production volume, budget, and timeline, from rapid prototyping tools to high-volume production molds.

Rapid/Prototype Tooling

Made from aluminum, these molds are fast and cost-effective. Ideal for producing 50 to 10,000+ real plastic parts for functional testing, market validation, or bridge production while awaiting high-volume tools.

Bridge Tooling

Often made from P20 tool steel, these molds offer greater durability than aluminum tools, capable of producing 10,000 to 50,000+ parts. They serve as an excellent intermediate step for pilot production or limited-run products.

Production Tooling

Constructed from hardened tool steel, these molds are built for millions of cycles. While they have the highest upfront cost, they offer the lowest per-part cost for high-volume mass production.

Custom Molds FAQ

What information do you need to quote a custom mold?

We primarily need your 3D CAD model (STEP file preferred) of the final plastic part. It is also highly recommended to include a 2D drawing that specifies critical tolerances, desired surface finish (SPI standard), and any special requirements.

How long does it take to make a mold?

Lead times vary significantly by mold type and complexity. A simple aluminum prototype tool can be made in as little as 2-4 weeks. A complex, multi-cavity hardened steel production tool can take 8-16 weeks or longer. We will provide a precise timeline with your quote.
