Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer with over two decades of experience in the hardware and spring industry. Since our establishment in 1998, we have been dedicated to producing high-performance industrial components. Our Chrome Silicon Steel Heavy Duty Die Spring, 1.5mm Wire Diameter, 1 Million Cycle Life, Industrial Grade represents the pinnacle of reliability and durability for demanding stamping and molding applications. This spring is engineered to withstand extreme pressures and repetitive loading, ensuring consistent performance in your production lines.
Our die springs are crafted from premium chrome silicon steel, a material known for its superior fatigue resistance, high tensile strength, and excellent heat tolerance. The 1.5mm wire diameter is carefully selected to balance flexibility and load capacity, making it suitable for a wide range of heavy-duty industrial tasks. With a guaranteed cycle life of 1 million cycles, you can expect minimal downtime and reduced maintenance costs. Each spring undergoes rigorous quality control, including shot peening and preset treatment, to ensure dimensional stability and consistent force output.
Below is a detailed overview of the key specifications and features of our Chrome Silicon Steel Heavy Duty Die Spring:
| Material | Chrome silicon steel (SAE 9254 / 6150 equivalent) |
| Wire Diameter | 1.5 mm (0.059 inch) |
| Free Length | Available in multiple lengths (customizable, contact us for options) |
| Outer Diameter | Varies by length; standard range 10–50 mm (customizable) |
| Load Capacity | High load rating, suitable for heavy stamping dies |
| Surface Treatment | Shot peened, preset, optional phosphate or black oxide coating |
| Cycle Life | 1 million cycles (minimum) under normal operating conditions |
| Ends | Closed and ground flat for perpendicularity |
Product Features & Benefits
- Superior Material Strength: Chrome silicon steel offers high tensile strength (up to 2000 MPa) and excellent fatigue life, ensuring the spring maintains its shape and force even after millions of cycles.
- Precision Manufacturing: Each spring is wound on advanced CNC coiling machines, followed by heat treatment and shot peening to relieve internal stresses and improve surface hardness.
- Consistent Performance: Preset treatment (compressing to solid height) eliminates initial set, providing stable load deflection characteristics from the first use.
- Corrosion Resistance: Optional coatings such as phosphate or black oxide protect against rust and extend service life in humid or aggressive environments.
- Customizable Dimensions: We offer a wide range of free lengths, outer diameters, and wire diameters. Custom orders are welcome with a quick turnaround.
- Industrial-Grade Reliability: Designed for heavy-duty applications like automotive stamping, metal forming, plastic injection molds, and general machinery.
- Cost-Effective Solution: With a 1-million-cycle lifespan, these springs reduce replacement frequency and downtime, lowering your total cost of ownership.
Our die springs are widely used in North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, and many other regions.

Frequently Asked Questions (FAQ)
Q1: What is the maximum operating temperature for this die spring?
A1: Chrome silicon steel springs can typically operate at temperatures up to 250°C (482°F) without significant loss of load capacity. For higher temperatures, please consult our technical team for alternative materials.
Q2: Can I get a sample before placing a bulk order?
A2: Yes, we offer samples for evaluation. Please contact us with your required dimensions and quantity, and we will provide a sample price and lead time.
Q3: How do you ensure the 1 million cycle life?
A3: Our springs are manufactured using high-grade chrome silicon steel and undergo shot peening and preset processes. We perform fatigue testing on random samples to verify cycle life meets the specification.
Q4: What is the tolerance on free length and outer diameter?
A4: Standard tolerance is ±1.0 mm on free length and ±0.5 mm on outer diameter. Tighter tolerances are available upon request for precision applications.
Q5: Do you offer custom color coding or marking?
A5: Yes, we can apply color coding (e.g., paint stripes) or laser marking according to your specifications. This is especially useful for easy identification in die sets.
Q6: What is the typical lead time for standard sizes?
A6: For standard sizes, lead time is usually 7–15 days after order confirmation. Custom sizes may require 15–25 days, depending on complexity.
Q7: Can these springs be used in corrosive environments?
A7: Yes, we offer optional phosphate or black oxide coating for mild corrosion resistance. For highly corrosive environments, we recommend stainless steel springs; please contact us for alternatives.
Q8: Do you provide technical support for spring selection?
A8: Absolutely. Our engineering team can help you select the correct spring dimensions and load rating based on your application requirements. Simply provide your die details and we will recommend the best solution.
