Advantages for Your Stamping & Cold Forming Operations
The rectangular cross-section allows the spring to store more energy per unit volume, reducing the required spring cavity size and enabling more compact die designs. This translates to lower material costs and higher press speeds. Each spring is tested for load accuracy within ±5% tolerance, ensuring consistent part quality over long production runs. The superior fatigue life minimizes downtime for spring replacement, directly improving your overall equipment effectiveness (OEE).
Our springs are widely used in automotive stamping, appliance manufacturing, and general metal forming industries. They are compatible with standard die spring retainers and can be supplied in pre-loaded or free-length configurations. For extreme conditions, optional protective coatings and high-temperature variants are available.

Frequently Asked Questions
-
Q: What is the typical lifespan of your rectangular wire die spring?
A: With proper installation and within rated load, our springs can sustain over 1 million cycles. The actual lifespan depends on operating conditions such as stroke length, frequency, and environment. -
Q: Can I get springs with a load capacity different from 1500N?
A: Yes, we offer custom load capacities from 100N to 5000N. Please provide your required dimensions and load to get a tailored solution. -
Q: Are these springs suitable for high-temperature environments?
A: Standard material works up to 120°C. For higher temperatures (up to 250°C), we recommend our high-temperature alloy option – please specify when ordering. -
Q: Do you provide samples for testing?
A: Yes, sample orders are welcome. We can produce a few pieces matching your specifications for evaluation before bulk order. -
Q: What is the lead time for standard orders?
A: For standard sizes, lead time is 15–20 days after confirmation. Custom sizes may take 25–30 days depending on complexity. -
Q: How do you ensure the spring’s load accuracy?
A: Each spring is tested using a digital force gauge and height gauge. We maintain ±5% tolerance on load at specified deflection, with records kept for traceability. -
Q: Can you provide a material certificate?
A: Yes, we can issue a mill test certificate for the raw material upon request, along with a dimensional inspection report.
