Q: How do you ensure the quality of your materials?
A: We use 100% virgin raw materials for all our high-performance plastics. Each batch undergoes stress-relief treatment (annealing) to ensure dimensional stability during machining.
Q: Do you offer free samples?
A: Yes, we can provide free small sample pieces (e.g., 100x100mm) for quality testing. Shipping costs are usually covered by the buyer.
Q: What is the tolerance for your plastic rods and sheets?
A: Our standard tolerance for thickness/diameter is +0.1mm to +2mm (depending on the material and size) to ensure you have enough margin for precision machining.
Q: Can you provide customized cutting or CNC machining?
A: Absolutely. We provide precise cutting-to-size services and can also perform CNC machining based on your 2D/3D drawings (PDF/STEP/DWG).
Q: What is your standard lead time for bulk orders?
A: For stock items, we ship within 3-5 days. For customized or out-of-stock items, it usually takes 10-15 days.
