- Flexibility for small and high-quantity production runs
- Repeat manufacturing for ongoing part needs
- Material guidance based on wear, friction, chemical resistance, impact, and temperature
- Reliable support from quote to finished part
Our Services
CNC Plastic Machining
We machine custom plastic parts for applications where accuracy, consistency, and part quality matter. Whether you need simple machined components or more complex parts with tight tolerances, our team works to deliver reliable results.
Learn moreCustom Plastic Fabrication
Our fabrication capabilities support a wide range of custom plastic components, including cut, formed, bonded, and assembled parts. We build solutions designed around your specs, your environment, and how the part will actually be used.
Learn morePrototypes to Production Runs
Some customers need one part. Others need an ongoing manufacturing partner. We handle both. From concept-stage prototypes to full production support, we help move projects forward efficiently.
Learn moreAssembly and Secondary Services
We also provide value-added support to help customers simplify sourcing and receive parts that are closer to ready for use.
Learn moreMaterials We Work With
Lehigh Valley Plastics machines and fabricates a wide range of performance and engineering plastics. If your application calls for better wear resistance, lighter weight, chemical resistance, electrical insulation, or a replacement for metal, we can help guide you toward the right material.

Frequently Asked Questions
What plastics do you machine and fabricate?
We machine and fabricate engineering plastics including Acetal (POM), Nylon (cast & extruded), UHMW-PE, PTFE, PEEK, Polycarbonate, PET/PETG, PVC, and high-performance grades like PPSU and PAI.
What tolerances can Lehigh Valley Plastics hold?
Typical CNC tolerances are ±0.005 in (±0.127 mm), with tighter tolerances possible depending on material, geometry, and part size. We review drawings to confirm achievable tolerances before production.
Do you provide one-off prototypes and production runs?
Yes. We support single prototypes, pilot builds, and full production runs. We also offer machining, fabrication, and assembly to streamline scale-up.
What are your typical lead times?
Prototype parts often ship in 1–2 weeks once drawings and material are approved. Production lead times vary by complexity and volume. Rush options are available when capacity and material allow.
Do you help with material selection for wear, friction, or chemical resistance?
Yes. Our engineers recommend materials for wear, friction, impact, and chemical resistance. Common selections include UHMW or Nylon for wear, Acetal for stability, and PEEK or PTFE for high-temperature and chemical environments.
Can you provide compliance and quality documentation?
We can provide C of C, material certs, and inspection reports. As an ISO 9001:2015 certified company, we maintain documented processes and traceability.
Do you serve Bethlehem, Allentown, Easton, and the greater Lehigh Valley?
Yes. We are based in Bethlehem, PA and serve customers across the Lehigh Valley and nationwide.
