Custom Plastic Parts for Electrical and Optical Applications
This category covers engineered plastic components used inside industrial electronics, lighting, sensors, communications, automation, and instrument equipment. We manufacture to drawing, matching material grade, flame retardancy, dielectric strength, transparency, surface finish, and dimensional tolerance to the function of each part.
Electrical Insulation
Insulators, busbar supports, terminal blocks, and connector housings produced in flame-retardant and high-dielectric engineering plastics for power electronics, control panels, and industrial equipment.
Optical & Transparent Parts
Light pipes, optical lenses, display windows, and light guides machined or molded in clear PC and PMMA, with controlled clarity, polish, and edge finish for reliable light transmission.
Housings & Enclosures
DIN rail enclosures, sensor housings, and control enclosures built to your PCB dimensions, terminal layout, mounting features, and assembly requirements.
Manufacturing Capabilities and Material Selection
Each component is reviewed against its electrical, optical, and mechanical function before we recommend a process and material. Parameters are part of the specification, not marketing language.
