## Opening
Your drawing is the starting point. We turn it into a finished fine blanking part with clean sheared edges and tight dimensional control. Every piece is verified before shipment. No guess
Your drawing is the starting point. We turn it into a finished fine blanking part with clean sheared edges and tight dimensional control. Every piece is verified before shipment. No guesswork, no surprises.
We are BQUQ, a precision manufacturing factory in Dongguan, China. Our metal stamping line has run for 20 years. We specialize in fine blanking—a process that delivers a smoother edge and better flatness than conventional stamping.

2. Inspection report per batch. You get a full inspection report with every shipment. It includes dimensional measurements, surface finish values, and material hardness data. We use CMM, optical projectors, and surface roughness testers. The report matches your drawing, point by point.
3. One factory for CNC + stamping + spring + heatsink. Your fine blanking part often needs a spring, a machined housing, or a heatsink. We do all four in-house. No outsourcing, no shipping delays between vendors. You send one drawing package, we deliver a complete assembly-ready part. This cuts your supplier management time in half.
Fine blanking parts go where precision and reliability are non-negotiable.
In each case, the part must hold tolerance after thousands of cycles. Fine blanking gives you that consistency. Our customers often move from prototypes to annual contracts once they see the edge quality and repeatability.
Q: How do you guarantee tolerance and quality? A: We use fine blanking presses with precision guides, then verify with CMM. Critical dimensions are checked 100%. Our standard tolerance is ±0.01 mm, and we hold tighter on request. Every batch ships with a dimensional report.
Q: What is your lead time for custom metal stamping? A: Prototypes take 7 days after drawing approval. Production runs take 15–25 days, depending on quantity and secondary operations. We quote exact dates with your order confirmation.
Q: Can you provide material certificates? A: Yes. We supply mill certificates for all raw materials, plus our own incoming inspection records. For medical or automotive, we add full traceability documentation at no extra cost.
We respond to every inquiry with a firm quote in 12 hours. Send your drawing, material spec, and quantity. We will confirm feasibility, tolerance, and price—no vague estimates.
