Every batch is traceable from coil to carton. We keep a sample of each batch for 24 months.
Three Reasons Buyers Send Us Their Drawings
1. Batch-traceable quality. Each production lot gets a unique batch number. You can trace material heat number, press settings, plating lot, and inspection records back to the exact coil and shift that produced your parts. No guesswork when a field failure occurs.
2. Inspection report per batch. You receive a dimensional report with actual measured values, not just a pass/fail note. We measure critical dimensions on 5 pcs per 1,000, and 100% check for burr, plating thickness, and flatness on request. The report is signed by our QC engineer and sent with the shipment.
3. One factory for CNC + stamping + spring + heatsink. Your junction box needs stamped terminals, a compression spring for the diode clip, and a heatsink for thermal management. Instead of coordinating three suppliers across time zones, you send one drawing package to one factory. We handle the stamping line, the spring coiling line, and the CNC heatsink line under one roof. That means one shipping point, one quality system, and one invoice.
Where These Parts Are Used
These stamped terminals and clips are found inside solar junction boxes for photovoltaic modules, typically 250 W to 700 W panels. Specific applications include:
Diode bypass clips – stamped copper clips that hold the bypass diode in place and carry current during partial shading.
MC4-compatible terminal blocks – flat stamped contacts with tin plating for low contact resistance.
Busbar connectors – formed copper pieces that connect the PV ribbon to the junction box output cable.
Cable strain relief clips – stainless steel stamped clips that lock the output cable in place.
Heat sink mounting clips – stamped springs that press the diode against the heatsink for thermal transfer.
These parts are also used in energy storage systems, EV battery connectors, and industrial control cabinets where vibration resistance and low contact resistance matter.
Q1: Do you really have no MOQ?
Yes. We run 50-piece prototypes and 5,000,000-piece annual contracts on the same lines. For small batches, we use single-hit tooling to avoid high die costs. For large batches, we move to progressive dies to lower per-piece price.
Q2: How do you guarantee ±0.05 mm tolerance?
Our dies are machined on wire-cut EDM and verified with a CMM before production. During stamping, we check the first article, then every 100th piece on an optical comparator. If a dimension drifts, we stop the press and adjust before the batch continues.
Q3: What is your typical lead time?
Prototypes: 7 days from drawing approval. Production: 15 days for quantities under 500,000 pcs. For urgent orders, we can split the batch and ship the first 20% within 5 days by air.
Q4: Can you provide material certificates?
Yes. Every coil comes with a mill certificate showing chemical composition and mechanical properties. We attach a copy to your inspection report. If you need third-party testing (SGS, TÜV), we can arrange it at cost.
