1. Batch-traceable quality Every lot gets a unique batch number. We record material heat number, press settings, tooling wear, and inspection results. If a problem appears in your assembly line, we trace it back to the exact stamping run. You get full traceability, not just a box of parts.
2. Inspection report per batch You receive a PDF inspection report with every shipment. It includes dimensional measurements, surface finish check, hardness values, and photos of critical features. Our QC team uses CMM, optical comparators, and push-pull gauges. We do not ship without the report.
3. One factory for CNC + stamping + spring + heatsink Your clip might need a stamped body, a CNC-machined mounting block, a coil spring, and a heatsink base. Most suppliers send you to four factories. We do all four in-house. One drawing, one PO, one shipping date. Fewer emails, fewer delays, fewer excuses.
Precision stamped heatsink clips hold power semiconductors, IGBT modules, and MOSFETs against cooling surfaces. They are critical in:
The clip must maintain constant pressure across temperature cycles. Our spring steel clips are heat-treated and stress-relieved to hold clamping force from -40°C to +150°C. We also offer beryllium copper for high-thermal-conductivity applications where electrical isolation is needed.

Q: What is your MOQ? A: No MOQ. We accept prototype orders of 100 pieces. For production, we recommend 5,000+ pieces for better per-unit pricing, but we will run 500 pieces if that is your need. Tooling cost is quoted separately and amortized into your part price after 50,000 pieces.
Q: How do you guarantee tolerance and quality? A: We use progressive dies with in-die sensors for real-time thickness monitoring. Critical dimensions are checked with CMM and optical comparators. Every batch gets a first article inspection and a final inspection report. We hold ±0.05 mm standard, ±0.02 mm on request.
Q: What is your lead time for custom stamped clips? A: Prototype tooling takes 7–15 days. Production samples are sent within 3 days of tool approval. Mass production takes 15–25 days depending on quantity. For urgent orders, we can split shipments – first 20% by air, rest by sea.
Q: Can you provide material certificates? A: Yes. We supply mill test certificates for raw material, heat treatment reports, and RoHS/REACH compliance documents. All materials are sourced from certified mills in China or imported from Japan/Korea upon request.
