Your drawing is the only spec we need. We machine, stamp, and wind custom springs to your exact dimensions, load, and finish. Every batch is verified before shipment.
We are BQUQ, a precision manufacturing factory in Dongguan, China. 20 years in business. CNC machining, metal stamping, springs, and heat sinks under one roof.
Tolerance: ±0.01 mm on wire diameter, ±0.05 mm on free length
Lead time: 7–12 days for standard custom springs
No MOQ – order 1 piece or 100,000 pieces
Material certs and inspection report included with every batch
CNC coiling, automatic spring winding, manual tooling for prototypes
Batch size
1 – 1,000,000 pcs
Inspection
100% dimensional check on critical springs, load testing per batch
Certifications
ISO 9001:2015, material test reports, RoHS/REACH on request
Three reasons buyers send us their drawings
1. Batch-traceable quality.
Each batch gets a unique lot number. We record material heat number, machine settings, and operator ID. If a problem appears in your assembly line, we trace it back to the exact coil and wire. No guesswork.
2. Inspection report per batch.
You get a PDF with measured dimensions, load curves, surface condition, and material certs. We test free length, outer diameter, and spring rate on a digital force tester. Every report is signed by our QC lead.
3. One factory for CNC + stamping + spring + heatsink.
Your spring might sit next to a stamped bracket, a CNC-machined shaft, or a heat sink. We make all of them in-house. You deal with one engineer, one shipping address, one invoice. Less coordination, fewer errors, faster turnaround.
Where these parts are used
Custom springs are not commodity parts. They carry loads, absorb shock, and control motion in demanding environments.
Automotive: valve springs, clutch springs, suspension coils, brake return springs
Medical devices: precision compression springs in syringes, surgical instruments, implantable delivery systems
Electronics: contact springs in connectors, battery terminals, switch mechanisms
Q1: Is there really no MOQ?
Yes. We accept orders from 1 piece. Prototypes and small batches use the same machines and materials as production runs. The only difference is unit price – smaller batches cost more per piece because of setup time.
Q2: What tolerance can you hold, and how do you verify it?
Standard tolerance is ±0.05 mm on free length and ±0.01 mm on wire diameter. For critical springs, we hold ±0.02 mm on free length. We verify with digital calipers, micrometers, and a spring force tester. The inspection report shows actual measured values, not just pass/fail.
Q3: What is your typical lead time?
Prototypes: 5–7 days. Production: 7–12 days depending on quantity and surface finish. Urgent orders can be expedited to 3 days for simple compression springs. We ship worldwide via DHL, FedEx, or sea freight.
Q4: Can you provide material certificates?
Yes. Every batch includes a material test report from the mill. We also provide RoHS, REACH, and ISO 9001:2015 documentation on request. If you need a specific material grade, we source it and verify the heat number.
