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.

CNC HIGH SPEED, HIGH PRECISION ROUTERS-PLASTIC ONLY
Chemwest utilizes three, Computer Numerical Control KOMO CNC 5’ X 10’ Routers for precise tolerance cutting of plastic component parts, and parts for plastic assemblies.
HIGH PURITY PIPING AND HIGH PURITY PLUMBING
Chemwest integrates high purity piping into our plastic process equipment based on the requirements of the project.
Materials commonly used in construction of our high purity process equipment include fluoropolymers:
- Socket Fusion polyvinylidene fluoride (PVDF)
- Butt Fusion Teflon polyfluoroethylene (PFA)
- Flared Teflon polyfluoroethylene (PFA)
Chemwest is a licensed UL-508a electrical panel shop.
Chemwest provides Electronic Testing Laboratories (ETL) labeling on our UL-508a electrical assemblies, and control panels.
Chemwest is licensed to build control boxes from FM-4910 material.
Chemwest utilizes hot air welding of thermoplastics in the construction of our plastic process equipment. Thermoplastic materials that must be either mechanically attached, or hot air welded include:
- Polypropylene (PP) and Polyvinyl Chloride (PVC)
- Polyethylene (PE)
- Polyfluoroethylene (PFA) Teflon
Chemwest extrusion welds the interior and exterior of large plastic process tanks in plastic manufacturing.
The plastic extrusion process places less stress on a material by laying down a weld equivalent to six passes with a normal welding gun.
- Polyvinyl chloride (PVC)
