Your Choice For Custom Fiber Reinforced Products

MGM Plastics has built custom fiberglass and fiber reinforced plastic (FRP) parts in San Marcos, CA since 1980 for customers throughout Southern California.

Our team uses hand lay, chopper gun and infusion processes and handles everything from engineering and design to production tooling and fixtures. We work with both room temperature and high temperature laminates, and we can build short-run, cost-effective tooling when a project does not call for a full production mold.

​

Why Choose Us?

Dependable service and quick responses are how we do business. If you have an idea for a fiberglass or composite part, call us at 760.744.8909 and our team will talk through materials, process and budget with you. We have focused on custom fiberglass and FRP fabrication for more than four decades and bring that experience to every project.

Our Process for Custom Fabricated Fiber Reinforced Products

We match the process to the part: hand lay for detailed laminations, chopper gun for large bulk layups, and custom tooling and molds for repeatable production.
