Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer with over two decades of expertise in metal components. Our Heavy Duty Die Spring (50mm Free Length, 1500N, Replaceable Design) is engineered specifically for demanding metal stamping applications. Designed to deliver consistent force, extended service life, and easy replacement, this spring ensures your press operations run smoothly with minimal downtime. Whether you are tooling up a new die or maintaining an existing press, our spring offers the reliability you need.
Manufactured from premium chrome silicon steel (50CrV4), our die spring undergoes carefully controlled heat treatment and shot peening to maximize fatigue resistance. The 1500N load capacity at 50mm free length makes it ideal for medium to heavy stamping tasks. The replaceable design means you can swap out worn springs quickly without replacing the entire assembly, saving both time and money. Below we detail the key features and specifications.
Key Features & Technical Specifications
- Material: High-quality chrome silicon steel (50CrV4) – excellent elasticity and fatigue life.
- Free Length: 50 mm – compact yet powerful for confined die spaces.
- Load Capacity: 1500 N (approx. 153 kg) – reliable force for consistent part forming.
- Replaceable Design: Springs are easily removed and reinstalled, reducing maintenance time.
- Surface Treatment: Shot peened + epoxy coating for corrosion resistance and extended life.
- Color Coding: Optional color identification (e.g., green for heavy duty) for quick recognition.
- Precision Tolerance: Manufactured to tight tolerances (typically ±1% on load, ±0.5 mm on length).
- Application: Metal stamping presses, progressive dies, transfer dies, and general tooling.
| Parameter | Value |
|---|---|
| Free Length (L0) | 50 mm |
| Load at L0 (approx.) | 1500 N |
| Wire Diameter (typical) | 4.5 mm (customizable) |
| Outer Diameter (typical) | 25 mm (customizable) |
| Color Code (optional) | Green (heavy duty) or other |
| Surface Treatment | Shot peened + epoxy coating |
Beyond the standard specifications, our spring offers several advantages for your press operation:
- Consistent Performance: Each spring is load-tested to ensure uniform force across multiple units, critical for multi-station dies.
- High Fatigue Life: Shot peening introduces compressive residual stresses, significantly extending the number of cycles before failure.
- Easy Replacement: The replaceable design allows you to change worn springs without removing the entire die set, reducing downtime to minutes.
- Corrosion Resistance: Epoxy coating protects against cutting fluids and humidity, ideal for long-term storage and harsh environments.
- Customizable Options: We can adjust wire diameter, outer diameter, load, and color coding to match your specific requirements.

Frequently Asked Questions (FAQ)
- Q: What material is this die spring made of? A: Our spring is manufactured from high-grade chrome silicon steel (50CrV4), known for excellent fatigue resistance and elasticity. It is also available in other materials upon request.
- Q: Can I use this spring for other applications besides metal stamping? A: Yes, while designed for stamping presses, it can be used in any application requiring a heavy duty compression spring with 50mm free length and 1500N load, such as dies, jigs, and fixtures.
- Q: Is the spring truly replaceable without special tools? A: The replaceable design allows easy removal and installation using standard hand tools. Detailed instructions are provided with each order.
- Q: How long is the typical lifespan of this spring? A: Lifespan depends on working conditions (cycle frequency, deflection, environment). With proper use (deflection ≤ 80% of maximum), it can last hundreds of thousands of cycles. Shot peening greatly extends fatigue life.
- Q: Do you offer custom sizes or load ratings? A: Absolutely. We can customize wire diameter, outer diameter, free length, and load capacity. Minimum order quantity may apply. Please contact us with your specifications.
- Q: What is the packaging and shipping method? A: Springs are packed in sturdy cartons or wooden crates, with protective oil and corrosion-proof wrapping. We ship via sea, air, or express from Tianjin, Qingdao, or Shanghai.
- Q: Do you provide samples for testing? A: Yes, sample orders are accepted. Sample cost and delivery time can be discussed. Please send us an inquiry.
- Q: What is the tolerance on load and length? A: Standard tolerance is ±1% on load and ±0.5 mm on free length. Tighter tolerances are available upon request.
