Frequently Asked Questions (FAQ)
-
Q: What materials do you use for EV water pump injection parts?
A: We commonly use PA66, PPS, PBT, and PA6T, often reinforced with glass fiber (30%–40%). Custom formulations are available based on your thermal and mechanical requirements. -
Q: Do you provide a Mill Test Report for every shipment?
A: Yes, we include a Mill Test Report (MTR) for each batch, certifying the material’s chemical composition and mechanical properties. This ensures full traceability for automotive audits. -
Q: What is your typical lead time for injection parts?
A: Standard lead time for existing molds is 15–25 days. For new mold development, it typically takes 30–45 days including design, tooling, and sample approval. We offer expedited services on request. -
Q: Can you customize the color of the parts?
A: Absolutely. We can match any RAL or Pantone color, and we also offer natural (uncolored) options. Color consistency is maintained through strict masterbatch control. -
Q: How do you ensure 100% dimensional inspection?
A: We use coordinate measuring machines (CMM) and optical comparators to check all critical dimensions. Each part is measured against the approved drawing, and non-conforming parts are rejected immediately. Inspection reports are available with each order. -
Q: Do you export to European and American markets?
A: Yes, we serve customers in North America, South America, Western Europe, Eastern Europe, and many other regions. We ship from ports in Jiangsu, Shanghai, and Shenzhen, and we can arrange door-to-door logistics. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ depends on the part complexity and material. Typically, for standard items, MOQ is 1,000 pieces. For custom molds, the MOQ can be negotiated. We also accept small trial orders for sample validation. -
Q: Do you offer after-sales technical support?
A: Yes, our 24/7 service means you can reach us anytime for technical questions, troubleshooting, or design modifications. We provide comprehensive support throughout the product lifecycle.
