Frequently Asked Questions (FAQ)
-
What materials are used for these water pump parts?
We use high-performance engineering plastics such as PPS, PA66+GF30, PPA, and PEEK, depending on your temperature and chemical resistance requirements. All materials are automotive-grade. -
Can you provide custom designs based on my pump model?
Yes, we offer full customization. You can send us your 3D CAD file or a sample, and we will design the mold accordingly. Our DFM service ensures optimal manufacturability. -
What is the minimum order quantity (MOQ)?
For new custom molds, the MOQ is typically 1,000–5,000 pieces per part number. For existing molds, we can accommodate smaller quantities. Please contact us for details. -
How long does it take to produce a new part?
Lead time for mold design and fabrication is 15–20 working days, followed by 10–15 working days for sample production. Mass production lead time is 30–45 working days after sample approval. -
Do you test the parts for 2000-hour continuous operation?
Yes, we perform rigorous endurance testing on sample parts to verify the 2000-hour continuous operation claim. This includes thermal cycling, pressure cycling, and coolant exposure tests. -
What certifications do your products have?
Our manufacturing process is certified under TS16969 (automotive quality management system). We also comply with RoHS and REACH regulations. Specific certifications can be provided upon request. -
Can you provide samples for evaluation?
Yes, we offer samples at cost. For standard parts, samples can be shipped within 7–10 days. For custom parts, sample lead time is included in the mold development timeline. -
How do you ensure quality consistency for mass production?
We use statistical process control (SPC) and in-process inspection (vision systems, dimensional gauges) to monitor each batch. Final inspection includes dimensional check, burst test, and visual inspection before shipment.
