We make mixed type industrial springs exactly to your drawing. Compression, tension, torsion, or wire forms—one order can include all of them. Every piece is verified before shipment. No guesswork, no tolerance surprises.
Tolerance: ±0.01 mm on critical dimensions
Lead time: 7–15 days for prototypes, 15–25 days for production
No MOQ—order one piece or one million
Material certs and full inspection report included with every batch
Specifications
We run CNC coiling machines and automated grinding lines in our Dongguan factory. All springs are made in China under ISO 9001:2015 control.
CNC coiling, hot coiling, grinding, shot peening, stress relieving, passivation
Tolerance
DIN 2095 grade 1, or ±0.01 mm on request
Surface finish
Plain, zinc plated, nickel plated, powder coated, or as-drawn
Batch size
1 – 1,000,000 pcs
Inspection
100% dimensional check on critical specs, load testing per batch
Three reasons buyers send us their drawings
1. Batch-traceable quality. Each batch gets a unique lot number. We track material heat numbers, machine settings, and operator IDs. If a problem appears in your assembly line, we trace it to the exact coil and wire.
2. Inspection report per batch. You receive a PDF with dimensional measurements, load values, and material test certificates. No extra charge. This report matches your drawing requirements line by line.
3. One factory for CNC, stamping, springs, and heat sinks. You send us a spring and a stamped bracket in the same envelope. We make both under one roof. Fewer suppliers, fewer logistics headaches, one quality standard.
Where these parts are used
Our mixed type springs go into real machines that run 24/7.
Automotive: valve springs, clutch return springs, brake pedal torsion springs
Medical devices: compression springs in insulin pens, tension springs in surgical staplers
Electronics: contact springs in battery connectors, torsion springs in laptop hinges
Industrial equipment: die springs in stamping presses, extension springs in conveyor systems
Energy: springs for circuit breakers, safety valves in power plants
If your part moves, absorbs shock, or stores energy, we can likely make it.
Questions buyers ask before ordering
Q: Is there really no MOQ?
A: Correct. We accept orders for one prototype piece. Production runs are priced per piece, so small batches cost more per unit but still get full quality checks.
Q: How do you control tolerance and quality?
A: We use CNC coiling machines with servo-controlled pitch adjustment. After coiling, we measure free length, outer diameter, and load at specified deflection on digital testers. Critical dimensions are checked at 100%, not by sampling.
Q: What is your lead time for custom springs?
A: Prototypes ship in 7–15 days after drawing approval. Production orders take 15–25 days, depending on quantity and surface treatment. Urgent orders can be expedited—we will tell you the exact cost before you commit.
Q: Can you provide material certificates?
A: Yes. Every batch comes with a mill test certificate for the wire material. We also provide RoHS and REACH compliance documents on request.
