JMMS Tooling for
Power Generation

JMMS specializes in manufacturing thermoset and thermoplastic tooling for power generation components:

We make tooling for:

  • Insulators
  • Breaker housings
  • Throw switches
  • Armatures

Our total program management begins with an assessment of your parts, material and production volume requirements. JMMS engineers can work with your production engineers as as part of our single-source solution.


Meet OEM quality and production benchmarks

We can work side by side with your engineers on-site during the mold maturation and optimization process. We review tryout data and optimize both part and mold design to reduce material usage and cycle time, and improve part quality.

Our primary objective is to meet OEM quality and production benchmarks, while lowering your total cost of ownership for tooling. We do this wit ISO-registered, documented QA and control over every phase of the mold lifespan:

  • Design and development
  • Prototype to production quantities
  • Design maturation and optimization
  • Operation
  • Maintenance and repair

Ongoing service and support in the Southeast

Our headquarters in Easley, SC position us for fast on-site service and lower freight costs for Southeastern manufacturers (we build and ship tooling coast to coast). JMMS dedicated maintenance and repair specialists provide the preventive maintenance your tooling requires, along with repairs and modifications for our tooling and other suppliers’.
