Reliable Rectangular Wire Die Spring – 60% Compression Ratio, 300kgf Load Capacity
Since 1998, Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of precision springs and wire products. Our Rectangular Wire Die Spring with a 60% compression ratio and 300kgf load capacity is engineered to deliver consistent performance in demanding die and mold applications. Manufactured from high-quality alloy spring steel, this spring features a compact 10mm inner diameter and 20mm outer diameter, offering a balanced combination of strength and space efficiency. With an annual export value exceeding US$5 million, we serve clients across North America, South America, Europe, Asia, Africa, and Oceania, ensuring reliable industrial solutions for diverse markets.
Key Features & Benefits
- High Compression Ratio (60%): Allows maximum deflection up to 60% of free length, reducing spring stack height and saving space in tooling assemblies.
- Exceptional Load Capacity (300kgf): Delivers high force output without premature fatigue, ideal for heavy-stamping dies and injection molds.
- Precision Dimensions (ID 10mm, OD 20mm): Tight tolerances ensure smooth fit into standard spring pockets, minimizing installation errors.
- Durable Rectangular Wire Profile: Optimized stress distribution compared to round wire, extending service life under cyclic loading.
- Versatile Surface Options: Available in phosphating, oil quenched, or colored finishes to resist corrosion and improve wear resistance (customization available).
- Customizable Free Length: We can produce springs with various free lengths (e.g., 25mm, 50mm, 75mm) to meet specific application requirements.
- Wide Application Range: Suitable for press dies, plastic molds, automotive stamping, mechanical springs, and general industrial machinery.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum deflection of this spring?
A: The spring can be compressed up to 60% of its free length. For example, if the free length is 50mm, the maximum deflection is 30mm, at which the load reaches 300kgf. -
Q: Can I use this spring in high-temperature environments?
A: Yes, the standard alloy steel material can operate up to +200°C. For higher temperatures, we can supply special materials upon request. -
Q: What is the typical lifespan of this die spring?
A: Lifespan depends on working conditions and deflection. Under normal industrial use (deflection ≤60% of free length), the spring can endure 500,000 to 1,000,000 cycles before fatigue. -
Q: Do you provide free length customization?
A: Absolutely. We can produce any free length between 20mm and 200mm, with a minimum order quantity (MOQ) of 100 pieces per specification. -
Q: Is the spring surface treatment corrosion-resistant?
A: Yes, the standard phosphating finish provides good corrosion protection. For outdoor or harsh environments, we recommend oil-quenched or black oxide surface. -
Q: How do I determine the correct spring for my die?
A: Consider the required load, available space (ID/OD), and required deflection. Our technical team can help you select or design the optimal spring – just provide your application parameters. -
Q: What packaging do you use for export?
A: Springs are individually wrapped in oil paper, then packed in cartons or wooden pallets to prevent damage during transit. We also offer custom labeling. -
Q: Do you offer samples before mass production?
A: Yes, we can provide samples for testing. The sample cost is negotiable, and it will be deducted from the first order's payment.
