Injection Molding Solutions for Power and Distribution Systems

Lewis Plastics produces precision-molded components for power and electrical distribution equipment where insulation, stability, and mechanical strength are essential. Our injection molding and insert molding capabilities help manufacturers build systems that perform reliably under heat, vibration, and continuous electrical load.

Durable Plastic Components for Power Equipment

We mold insulating barriers, covers, switchgear housings, and terminal supports for electrical assemblies that demand consistent performance over long service life. Each part is engineered for strength, dimensional control, and dielectric integrity. Many programs use plastic insert molding to integrate threaded metal inserts or conductive elements without compromising insulation performance.

Material Expertise for Electrical Applications

Power and distribution environments require resins with excellent dielectric strength, heat resistance, and creep stability. Lewis Plastics works with nylon, polycarbonate, ABS, and glass-filled engineering thermoplastics to meet those needs. Engineering and tooling teams evaluate resin flow and mold design to ensure proper filling, shrinkage control, and dimensional accuracy across every production run.

With decades of experience in injection molding manufacturing, we understand how to balance safety, strength, and cost efficiency in electrical applications.

End-to-End Manufacturing Support

Our vertically integrated approach brings injection molding, insert molding, and secondary services like machining, trimming, and assembly together under one roof. Warehousing options, including KanBan and vendor-managed inventory (VMI), support consistent part availability and reduce downtime for manufacturers managing complex supply chains.

Quality Systems That Protect Performance

Every electrical component we produce is backed by ISO 9001:2015 certification and validated through inspection in our climate-controlled lab. Statistical Process Control (SPC) and detailed dimensional verification help ensure stable quality and repeatable results.
