Introduction — Ahmedabad-based Die Spring Manufacturer
Durga Spring Industries, Ahmedabad, is a trusted Ahmedabad-based die spring manufacturer delivering high-load, long-life springs for press tools, moulds, and precision industrial mechanisms. Our die springs are engineered for stable force, minimal set, and repeatable performance under high compression cycles. With a modern facility, disciplined quality control, and fast project turnaround, we support OEMs, tool rooms, and maintenance teams across automotive, plastic injection, metal stamping, and general engineering.
Working Principle & Process Flow — Die Springs
Die springs store mechanical energy when compressed and release it as a controlled restoring force for tool return, ejection, and balanced pressure. At Durga Spring, production begins with high-quality alloy steel selection followed by precision coiling and heat treatment for strength and fatigue resistance. Springs are stress-relieved, ground for parallel seating, and finished for corrosion protection. Each batch undergoes dimensional checks, load-rate verification, and cycle-life testing to ensure consistent performance in demanding press environments.

Maintenance & Safety Tips — Die Springs
ChecklistDurga Spring
Monthly / Quarterly
Inspect springs for cracks, corrosion, or length reduction; replace sets together to maintain uniform force.
Verify preload and working stroke remain within recommended limits; avoid solid height impact.
Clean guide bores and retainers; ensure proper lubrication where applicable to reduce wear.
Operating Best Practices
Use correct spring class and quantity to distribute load; avoid over-compression beyond suggested deflection.
Install with proper guidance—keep springs square to plates and seated on flat surfaces.
Replace damaged retainers, guide pins, or misaligned hardware that may side-load the spring.
FAQs
Q1
What are die springs used for?
Die springs provide reliable return force and pressure in stamping dies, mould ejectors, press brakes, fixtures, and automated jigs operating under repetitive high loads.
Q2
Can you supply custom sizes and load classes?
Yes. We manufacture made-to-order lengths, outside/inside diameters, and load classes to suit your tool design and stroke limits.
Q3
How do I choose the right number of springs for a die set?
Calculate total required force at working height, select suitable class and distribute across multiple springs to minimize stress and avoid reaching solid height.
Q4
Do you provide color coding for quick identification?
On request, we offer distinct banding/marking so maintenance teams can quickly recognize spring class during changeovers.
Q5
What information should I share to get a quote?
Please share OD, ID, free length, working stroke, required force at height, quantity, and application notes (die/mould/fixture) for a precise quotation.
