Electrical Insulation

Manufacturing Finished Parts From Non-Metallic Electrical Insulation Materials

Multiple processing options for a wide variety of thermo and thermoset plastic parts

Machining and fabricating parts from electrical insulation materials is something MetPlas has done since our founding back in 1981 and it continues to be a significant part of our business today. Materials used for electrical insulation can be abrasive on tooling and very dusty but we’ve refined out processes over the past 40 years to become experts in the industry. Some common materials we make parts from include:

Products we’ve supplied custom insulation components for include:

  • Switchgear
  • Drives
  • Transformers
  • Circuit Breakers
  • Electrical busways
  • Motors
  • Inverters
  • Power supplies
  • Uninterruptable Power Supplies (UPS)
