FAQ

1. Q: What engineering plastic materials do you mainly produce?
A: We specialize in high-performance engineering plastic products such as PTFE (Polytetrafluoroethylene), PEEK (Polyetheretherketone), Nylon, and UHMW-PE (Ultra-High Molecular Weight Polyethylene).

2. Q: What are the key advantages of PTFE material?
A: PTFE offers excellent chemical resistance, high and low temperature stability (-200°C to +260°C), an extremely low friction coefficient, and outstanding insulation properties.

3. Q: Can you provide customized sealing components?
A: Yes, we support customization of seals (e.g., O-rings, gaskets, sealing rings) in various shapes, sizes, and materials based on customer drawings or technical requirements.

4. Q: Which industries are your products suitable for?
A: Our products are widely used in industries such as chemical processing, semiconductors, automotive, medical, food machinery, aerospace, and power equipment.

5. Q: Do you comply with international certification standards?
A: Our production follows the ISO 9001 quality management system, and some products are certified by FDA, RoHS, REACH, etc., meeting diverse market requirements.

6. Q: What is the minimum order quantity (MOQ)?
A: MOQ for standard products is relatively low, while custom parts depend on specifications. We strive to accommodate trial orders and small-batch requests.

7. Q: What is the lead time for delivery?
A: Standard products typically take 7-15 days, while custom parts require 2-4 weeks depending on complexity (subject to confirmation after order placement).

8. Q: How do you ensure the pressure and temperature resistance of seals?
A: We optimize material selection, conduct simulation tests, and implement strict production process controls (e.g., sintering, machining) to ensure performance compliance.

9. Q: Do you offer technical support and samples?
A: Yes, we provide free technical consultation and can send samples based on project needs (some samples may incur a nominal cost fee).

10. Q: How are products packaged and shipped?
A: We use dust-proof and moisture-proof packaging, with options for vacuum bags or wooden cases. Global logistics (air/sea/express) are supported.
