Custom CNC Machining Polystyrene Parts

We can achieve tolerances as tight as ±0.002″ (±0.05mm) on critical dimensions for polystyrene parts. Standard tolerances are typically ±0.005″ (±0.13mm) depending on part geometry and size. Our precision machining equipment and quality control systems ensure consistent dimensional accuracy across production runs.

Standard lead time for custom polystyrene CNC machined parts is 5-7 business days after order confirmation. Rush orders can be accommodated in 2-3 days with expedited processing. Lead times may vary based on part complexity, quantity, and current production schedule.

We offer various surface finishes including as-machined (standard), polished, textured, and painted finishes. Polystyrene naturally provides a smooth surface finish directly from machining. Additional finishing options include vapor polishing for optical clarity and custom texturing for aesthetic or functional requirements.

We accept all major CAD file formats including STEP, IGES, STL, SolidWorks, AutoCAD, and 2D technical drawings (PDF/DWG). For best results, provide 3D CAD files with dimensional tolerances and surface finish requirements clearly specified.

Yes, we provide complete material certificates and mill test certificates for all polystyrene grades used in production. Our documentation includes material composition, mechanical properties, and traceability information to ensure compliance with your quality requirements and industry standards.

We have no minimum order quantity requirements. Whether you need a single prototype or thousands of production parts, we can accommodate your needs. Our flexible manufacturing approach allows us to efficiently handle both low-volume and high-volume orders with consistent quality and competitive pricing.
