3D Printed Injection Mold Tooling | Westec Plastics | Premier Medical Injection Molding and Custom Plastic Manufacturers in California

3D Printed Cavities and Cores for Faster, More Flexible Tooling

Westec Plastics uses the Mantle P-200 metal 3D printer to manufacture steel cavities and cores with unmatched speed and precision. As one of the first molders to integrate this technology directly into our tooling workflow, we help OEMs accelerate product development, reduce tooling costs, and validate designs earlier — all while maintaining production-grade accuracy.

Our 3D printed mold inserts are produced in P20 and H13 steel, ensuring durability and performance identical to conventionally machined tooling.

Why 3D Printed Injection Mold Tooling is Transforming the Industry

Traditional tooling timelines can slow down early development, especially when multiple design iterations are required. Metal 3D printing solves that challenge by enabling:

Rapid creation of complex parts
Faster DFM validation
Shorter sampling and approval cycles
Lower upfront tooling costs

This makes it an ideal solution for medical, biotech, diagnostic, and other high-precision components where speed and accuracy are critical.

Mantle P-200: Precision Steel Tooling, Delivered Faster

Mantle’s patented hybrid printing process produces steel mold components with:

P20 and H13 material properties
Tight dimensional accuracy
Excellent surface finish
Repeatability suitable for production environments

Westec’s toolmakers then complete the high-precision finishing steps, ensuring every insert meets the required tolerance and performance expectations.

Accelerate Tooling Lead Times by Up to 70%

What once took 12 weeks now takes as little as 2–4 weeks. 3D printed cores and cavities enable:

Rapid pilot molds
Early functional testing
Faster PPAP and validation
Reduced idle time between design revisions

This speed helps OEMs meet aggressive development schedules — especially in regulated markets.
