Precision Machining for High-Performance Plastics
Plastic machining is different from metal machining. Engineering plastics require careful attention to heat, stress, material movement, tooling, finish, and dimensional stability. The right material and machining process can help improve performance, reduce part failure, and support long-term reliability.
Modern Plastics works with a wide range of high-performance plastics, including materials selected for wear resistance, chemical resistance, electrical insulation, dimensional stability, impact strength, low friction, and high-temperature performance.

Precision Plastic Machining FAQs
What is plastic machining?
Plastic machining is the process of cutting, shaping, drilling, milling, or turning plastic materials into finished components. Unlike metal machining, plastic machining requires careful attention to material movement, heat, stress, tooling, and dimensional stability.
What types of plastic parts can Modern Plastics help machine?
Modern Plastics can help with custom machined plastic parts such as spacers, bushings, insulators, wear pads, guide rails, rollers, brackets, plates, fixtures, medical components, semiconductor parts, and drawing-based replacement parts.
What materials are commonly used for machined plastic parts?
Common materials for precision plastic machining include Acetal / Delrin®, PEEK, PTFE, UHMW, nylon, ULTEM™ / PEI, PVDF, polycarbonate, HDPE, PPS, PAI, and other engineering plastics. The best material depends on the part’s application, environment, tolerance needs, and performance requirements.
Can you machine plastic parts from a customer drawing?
Yes. Customers can upload a drawing, print, or part specification for review. Including material requirements, dimensions, tolerances, quantity, and application details helps the team prepare a more accurate quote.
Can Modern Plastics help choose the right material?
Yes. Modern Plastics can help review your application and recommend material options based on wear resistance, chemical resistance, electrical insulation, dimensional stability, impact strength, temperature performance, and compliance needs.
