Shaped High-Voltage Casing Parts in FR-4 / G10
Machined casing, bushing and insulator shapes from wound epoxy glass. Casing and bushing parts are wound tube taken to a finished shape: tapers, steps, grooves and bores machined to the assembly drawing. We hold concentricity between bores and OD so the part centers in its housing. Creepage is cut or molded to your requirement.

Why FR-4 / G10 epoxy glass for this application
FR-4/G10 machines into stable, low-CTI insulating profiles with predictable dielectric and mechanical values, and the shape is cut to your drawing rather than forced onto a stock profile.
p>Sharp machined corners are stress risers in HV. Keep radii per class. Confirm CTI and tracking class against polluted environments. keep radii per class. Confirm CTI and tracking class against polluted environments.Standards: IPC-4101 / ASTM D709, IEC 60672, UL 94 V-0.
Feature and remaining-wall review
For Shaped High-Voltage Casing Parts in FR-4 we use diamond-coated tooling for clean edges and CNC turning, grinding and drilling to drawing. Controlled moisture content keeps dimensional stability where it should be. Feature depth, edge distance and remaining wall are reviewed against critical geometries, and capability is confirmed on your print, not from a blanket tolerance.
Inspection and traceability
We state the control plan with you. Batch traceability links raw material lot to finished part.
- First-article inspection (FAI) per your plan
- In-process dimensional checks at every station
- Batch certificate of conformance (COA) supplied on request
- Lot traceability to incoming material certificate
- Dielectric strength and insulation resistance testing available on request
