At Anping County Boli Hardware Wiremesh Products Factory, we specialize in manufacturing high-precision custom springs for demanding industrial applications. Since 1998, we have been a trusted manufacturer in the hardware and wiremesh industry, delivering reliable components to customers worldwide. Our Custom Spring 304 Stainless Steel ±0.01mm Tolerance Compression Spring is designed to meet the exacting requirements of precision machinery, offering exceptional dimensional accuracy, corrosion resistance, and long service life. Whether you need a prototype or mass production, our engineering team ensures each spring is tailored to your specifications.
This compression spring is crafted from premium 304 stainless steel, known for its excellent mechanical properties and resistance to rust and chemicals. The key feature of our product is its ±0.01mm tolerance, which guarantees consistent performance in critical applications such as automotive components, medical devices, electronics, and industrial automation. With our advanced CNC coiling machines and rigorous quality control, we can achieve tight tolerances while maintaining cost-effectiveness.

Our compression springs are ideal for precision machinery where consistent force and minimal deviation are essential. They are widely used in valve assemblies, solenoid actuators, pressure switches, probes, and micro-positioning systems. The 304 stainless steel material provides excellent fatigue resistance, making these springs suitable for dynamic loading cycles.
We understand that every application has unique requirements. That's why we offer complete customization – from spring rate (k-value) and solid height to special end treatments. Our skilled engineers work closely with you to produce a spring that fits perfectly and performs reliably. We also provide free technical consultation to help you select the optimal design.

Frequently Asked Questions (FAQ)
Q1: What is the minimum order quantity (MOQ) for custom compression springs?
A: Our MOQ is flexible. For standard sizes, we can start from 100 pieces. For fully custom designs, we accept orders as low as 50 pieces for prototypes. Large production runs are also welcome.
Q2: Can you achieve a tolerance tighter than ±0.01mm?
A: Yes, we can achieve ±0.005mm or even tighter tolerances for special applications. Please provide your specific requirements, and our engineering team will evaluate the feasibility.
Q3: What is the typical lead time for prototypes and mass production?
A: Prototypes usually take 5–7 working days after design confirmation. For mass production, lead time is around 2–3 weeks depending on quantity and complexity. Urgent orders can be expedited.
Q4: Do you offer free samples for testing?
A: We provide samples at cost price for custom springs. For standard sizes, we may offer a few free samples. Shipping charges apply. Please contact our sales team for details.
Q5: Can you use other stainless steel grades like 316 or 17-7PH?
A: Yes, we can produce springs from 316 stainless steel, 17-7PH, or other materials upon request. Each material has different properties; we can help you choose the best option for your environment.
Q6: How do I specify the spring dimensions for a custom order?
A: You can provide a drawing, a sample, or just the key parameters: wire diameter, outer diameter, free length, number of active coils, end type, and desired load/deflection. Our engineers will help finalize the design.
Q7: What surface treatments are available for corrosion protection?
A: Standard treatment is passivation (for 304 SS). We also offer oil-dipped, zinc plating, epoxy coating, or other finishes as needed. Please specify your requirement.
Q8: Do you export to my country?
A: We export to North America, South America, Europe, Southeast Asia, Africa, Oceania, the Middle East, and many other regions. Our annual export value of US$5–10 million demonstrates our global reach. We are experienced in international shipping and customs documentation.
