Frequently Asked Questions About CNC Plastic Machining
What is your minimum order quantity (MOQ)?
We have NO minimum order quantity. Whether you need a single prototype or thousands of production parts, we're equipped to handle orders of any size. This flexibility makes us ideal for R&D projects, custom replacements, and production runs.
What tolerances can you achieve with plastic CNC machining?
Our standard machining tolerance is ±0.03mm (±0.0012") for most plastics. For stable engineering plastics like PEEK, POM, and G-10, we can achieve even tighter tolerances based on part geometry. Critical dimensions should be clearly specified on your technical drawings.
Which file formats do you accept?
We prefer 3D CAD files in STEP (.stp, .step) or IGS (.igs, .iges) format for the most accurate quotes. We also accept 2D drawings in DWG, DXF, or PDF format. Our engineering team can work with you if you need assistance with file preparation.
What is your typical lead time?
Standard lead times are 5-7 business days for most CNC machined plastic parts. Simple parts or urgent prototypes can often be completed in 2-3 days. Complex multi-axis parts or large production runs may require additional time. Rush service is available for critical deadlines.
Do you offer free shipping?
Yes! We offer free standard shipping to many countries and regions worldwide. Express shipping is available at additional cost for urgent deliveries. Contact us for specific shipping information to your location.
Can you machine custom plastic materials I provide?
Yes, we can machine customer-supplied materials. However, we recommend using our stock materials when possible to ensure consistent quality and material properties. If you have special material requirements, our team can source specialty plastics for your project.
