Customer-Specific Parts

Chemwest offers innovative manufactured solutions for industry and provides services for plastic fabricating & plastic machining customer specific plastic parts in small to medium quantities. Original equipment manufacturing OEM is a strong division of Chemwest, creating your company’s standard parts from OEM drawings. First article inspection (FAI) is standard when manufacturing quantities for OEM. Chemwest quality department performs FAI on request and as needed. All FAI documentation is kept on file. Tight tolerance plastic machined parts can be made in higher volumes and hold and verify tolerance.

Chemwest provides design services for those customers who do not have in-house capabilities.
