1.Tension Spring Quick Detail

As a custom extension spring expert, Tingfeng Hardware is committed to providing end-to-end solutions from concept to volume production. We specialize in manufacturing precision extension springs within the wire diameter range of Φ0.1-12mm, with particular expertise in the forming and strengthening of various loop types. We combine 15 years of process experience, advanced WAFIOS equipment, and a stringent IATF quality management system to ensure rapid response (48-hour samples) and stable supply (500K pcs/day capacity). Our goal is to enhance your product's market competitiveness through reliable spring performance

2.Tension Spring  Product Description

The core of extension spring design lies in balancing load, travel, lifespan, and installation method. We deeply understand the importance of loops as stress concentration points and primary failure modes. Therefore, our engineering service focuses on optimizing the end design for you—whether selecting the most suitable loop type, determining the optimal bend radius, or suggesting strengthening processes (e.g., butt welding, crimping). We use high-quality wire and controlled coiling tension, combined with precise heat treatment, to ensure the spring maintains stable mechanical properties even after long-term extension cycles, thereby extending the service life of your entire system.
