- Helps contain chips and airborne particles
- Clear polycarbonate provides full cutting visibility
- Manufactured for specific router configurations
- Compatible with dust collection systems
Ideal for: CNC routers, plastic fabrication equipment, woodworking machinery, and composite machining operations.
Custom Plastic Guards & Shields
Many applications require protection beyond standard guard designs. Chemwest manufactures fully customized shields and guards from customer drawings, samples, or concept sketches.
- Built to exact dimensions and mounting requirements
- Manufactured from drawings, samples, sketches, or written descriptions
- Available in clear, opaque, or colored plastics
- Fabricated and CNC machined in-house
- Prototype quantities through production runs
Ideal for: Any industrial, laboratory, or semiconductor application requiring custom operator protection.
Plastic Materials for Safety Shields & Guards
Shield materials are selected according to impact resistance, chemical exposure, visibility requirements, and cleanroom compatibility. Chemwest works with a broad range of engineering thermoplastics to ensure each guard performs reliably in its intended environment.
- Polycarbonate: High-impact, optically clear material widely used for machine guards and splash shields. Lexan® is a common trade name.
- Clear PVC: Economical transparent shielding for splash protection and equipment viewing panels.
- Acrylic: Excellent optical clarity and surface hardness for display-quality shields and lower-impact applications.
- Lexan®: Premium polycarbonate material offering exceptional impact resistance.
- Polypropylene (PP): Chemical-resistant, FM4910-rated material suited for corrosive process environments.
- HDPE / UHMW: Durable, wear-resistant plastics for heavy-duty industrial guards.
- Other Solid Plastics: Additional thermoplastics available based on chemical, mechanical, or temperature requirements.

Frequently Asked Questions
What types of plastic safety shields does Chemwest manufacture?
Chemwest manufactures splash shields, finger guards, chain guards, knife guards, router guards, and fully custom plastic safety shields built to customer specifications.
What plastic materials are available for safety shields?
Available materials include polycarbonate, Lexan®, acrylic, clear PVC, polypropylene, HDPE, UHMW, and other engineering thermoplastics selected according to the application.
Can you build a custom shield from a drawing or sample?
Yes. Chemwest manufactures custom guards from customer drawings, sketches, existing parts, samples, or written descriptions, with engineering support available when needed.
Are your plastic shields suitable for use in a cleanroom?
Yes. Cleanroom-compatible materials are available for semiconductor fabrication facilities, pharmaceutical production, and other controlled manufacturing environments.
How do plastic safety shields compare to metal guards?
Plastic guards provide corrosion resistance, electrical insulation, reduced weight, and, when manufactured from clear materials such as polycarbonate or acrylic, allow operators to maintain visibility while equipment remains protected.
Do your machine guards meet OSHA requirements?
Chemwest designs guards to satisfy the physical protection requirements of each application. Final compliance with OSHA machine guarding standards (29 CFR 1910.212) should be verified by the customer’s safety team.
What is the minimum order quantity for custom safety shields?
