Every stainless steel touch spring in this collection is made to your exact print—wire diameter, coil count, free length, and load curve. We verify each dimension before shipment. No guesswork.
This is precision manufacturing for engineers who need repeatable spring performance in high-touch or high-cycle applications.
Tolerance: ±0.02 mm on wire diameter, ±0.05 mm on free length
Lead time: 7–12 days for prototypes, 15–20 days for production runs
No MOQ—order 10 pieces or 100,000
Material: SUS301, SUS304, SUS316L, or your specified alloy
Batch traceability: every lot has a unique heat number and inspection record
100% dimensional check on critical features, batch load testing
Batch size
No MOQ—pilot runs from 10 pieces
Lead time
7–12 days prototype, 15–20 days production
Certifications
ISO 9001:2015, material certs per batch
Three Reasons Buyers Send Us Their Drawings
1. Batch-traceable quality.
Each spring gets a lot number. We record wire heat, machine settings, and operator ID. If a field failure occurs, we trace it to the exact batch in minutes. You get a full traceability report with every shipment.
2. Inspection report per batch.
We don't just say it's good. You receive a dimensional report, load test curves, and surface finish readings for every batch. Our QC lab uses digital force testers and optical comparators. Data is real, not estimated.
3. One factory for CNC + stamping + springs + heat sinks.
Your assembly likely needs more than springs. We run four production lines under one roof. Send us the full BOM—we machine the housing, stamp the contacts, coil the spring, and CNC the heat sink. One supplier, one quality system, one shipping date. Fewer headaches for you.
Where These Parts Are Used
Stainless steel touch springs are not generic coils. They are engineered for specific contact and force requirements.
Consumer electronics: Battery contacts in earbuds, smartwatches, and handheld devices. Springs must hold consistent force over 10,000+ cycles.
Medical devices: Spring-loaded probes in diagnostic equipment. SUS316L for corrosion resistance and biocompatibility.
Automotive: Sensor contacts in throttle bodies and brake systems. Vibration resistance and temperature stability are critical.
Q: What is your MOQ?
A: No MOQ. We run pilot batches of 10–50 pieces for prototyping. Production pricing starts at 1,000 pieces, but we accept smaller orders at a slightly higher unit rate.
Q: How do you guarantee tolerance and quality?
A: We use CNC coiling machines with closed-loop wire feed control. Every batch is sampled at 5% or 10 pieces, whichever is greater, for dimensional and load testing. Critical dimensions are 100% inspected. You get the data.
Q: What is your lead time for custom springs?
A: Prototypes ship in 7–12 days after drawing approval. Production runs take 15–20 days. If you need faster, we can split the batch and air-ship the first portion.
Q: Can you provide material certificates?
A: Yes. Every batch includes a mill certificate for the wire material, showing chemical composition and mechanical properties. We also provide heat treatment records and surface finish reports on request.
