Mold Spring 2.5mm Wire 35mm OD 180mm Long Technical Support and Free Replacement
Product Spotlights
Since 1998, Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer in the hardware and spring industry. Our Mold Spring 2.5mm Wire 35mm OD 180mm Long is designed to meet the rigorous demands of injection molding, stamping, and die-casting applications. With a proven track record of exporting US$5-10 million annually to global markets, we combine technical expertise with dedicated customer support. Each spring comes with free replacement and professional technical support, ensuring your production runs smoothly without unexpected downtime.
This mold spring is engineered from high-grade spring steel, offering excellent fatigue life and consistent performance under repeated compression. The 2.5mm wire diameter and 35mm outer diameter balance strength and flexibility, while the 180mm free length provides ample working stroke for medium to heavy-duty mold applications. Whether you need to replace worn-out springs in existing dies or design new tooling, our product delivers reliable force and dimensional stability.
Key Features & Technical Specifications

Frequently Asked Questions (FAQ)
-
Q: What is the maximum working temperature for this spring?
A: The spring can operate continuously at temperatures up to 120°C. For higher temperatures, please inquire about our special alloy options. -
Q: Can I get a different wire diameter or outer diameter?
A: Yes, we offer fully customizable springs. Provide your required dimensions and load specifications, and we will produce accordingly. -
Q: How is the free replacement policy implemented?
A: If any spring fails due to material or manufacturing defects within a reasonable period (e.g., 6 months), we will send a replacement at no cost. Shipping charges may apply for remote areas. -
Q: Are these springs suitable for high-speed stamping dies?
A: Yes, with a polished surface and optional shot peening, they handle high cycle rates. However, for very high speeds (e.g., >300 strokes/min), we recommend a custom design with enhanced fatigue resistance. -
Q: What is the lead time for standard sizes?
A: Standard sizes (2.5x35x180) are usually in stock and ship within 3-5 working days. Custom orders take 10-15 days depending on quantity and complexity. -
Q: Do you provide load/force data?
A: Yes, we can provide load-deflection curves and spring rate calculations upon request. Our technical support team will help you choose the right spring. -
Q: Can I get a sample before bulk order?
A: Absolutely. Sample orders are welcome. We can ship samples via courier, and the cost may be deducted from your first bulk order. -
Q: What payment methods do you accept?
A: We accept T/T, L/C, and other common trade terms. For small orders, PayPal or Western Union may be available.
