Custom Plastic Process Fixturing for Semiconductor & Industrial Applications
Chemwest designs and manufactures plastic process fixturing solutions that securely hold, position, and stage critical components during preventive maintenance, equipment installation, cleaning, and manufacturing operations. Every fixture is custom-built from customer drawings, sketches, sample parts, or concepts using advanced plastic fabrication and precision CNC machining.
From simple support fixtures to complex multi-component assemblies, Chemwest delivers durable process fixturing manufactured to meet the dimensional, chemical, and cleanroom requirements of semiconductor fabs and demanding industrial environments.
What Is Plastic Process Fixturing?
Plastic process fixturing refers to custom-built devices used to securely hold, position, support, or organize components while they move through specific manufacturing or maintenance processes. These fixtures help maintain consistent positioning during preventive maintenance, component cleaning, inspection, staging, and equipment installation while reducing the risk of damage to valuable parts.
Unlike standard off-the-shelf fixtures, custom plastic process fixtures are engineered around the exact geometry, material requirements, and operating environment of each application. They are commonly manufactured from high-performance thermoplastics that provide excellent chemical resistance, dimensional stability, and cleanroom compatibility for semiconductor and industrial processes.

Built From Your Drawings, Samples, or Concepts
Every manufacturing process is different, which is why Chemwest doesn’t rely on standard fixture designs. Whether you have a complete engineering drawing, a rough sketch, an existing fixture, or simply an idea of what you need, our team works with you to develop plastic process fixturing that matches your application.
Our engineers evaluate each project based on component geometry, operating conditions, chemical exposure, and manufacturing requirements to recommend the most suitable design and fabrication method.
1. Share Your Requirements
Provide a drawing, sketch, sample fixture, or written description of your application. Formal engineering drawings are not required to begin the design process.
2. Engineering Review
Our engineering team reviews your application, evaluates material compatibility, and determines whether fabrication, CNC machining, or a combination of both will provide the best solution.
3. Fabrication & Machining
Fixtures are manufactured entirely in-house using precision plastic fabrication, CNC machining centers, routers, turning centers, and hot-air welding under Chemwest’s ISO 9001 quality system.
4. Inspection & Delivery
Each fixture undergoes dimensional inspection before shipment. Completed assemblies are packaged for delivery, and Chemwest supports future design revisions, replacement fixtures, and repeat production orders as your process evolves.
Plastic Materials for Process Fixturing
Selecting the correct material is just as important as the fixture design itself. Chemwest recommends materials based on chemical compatibility, operating temperatures, mechanical performance, and cleanroom requirements to maximize fixture life and process reliability.
Common materials include:
- Polypropylene (PP): Excellent chemical resistance, FM4910 fire-rated options available, widely used for general process fixturing.
- PVDF (Polyvinylidene Fluoride): High-purity material with exceptional resistance to aggressive semiconductor chemistries.
- CPVC: Suitable for elevated-temperature applications and corrosive processing environments.
- PTFE (Teflon): Ultra-high purity with outstanding chemical resistance and extremely low contamination characteristics.
- PVC: A cost-effective solution for general industrial fixtures where demanding chemical resistance is not required.
- UHMW / HDPE: Low-friction, wear-resistant plastics ideal for sliding surfaces and contact applications.
- Polycarbonate: Clear, impact-resistant material that allows visual inspection during cleaning, staging, or assembly operations.
Chemwest can also recommend alternative engineering plastics when applications require specialized thermal, chemical, or mechanical performance.
