Product Specification

Product Description

Our coil torsion springs are engineered to deliver precise rotational force and long-lasting performance in demanding industrial environments. Compared with standard springs on the market, our products are manufactured using high-precision spring forming equipment and strict material selection, ensuring consistent torque output and excellent fatigue resistance.

The springs can be produced from stainless steel, carbon spring steel, or music wire, allowing them to perform reliably in both indoor and outdoor conditions. Through optimized coil design and accurate leg positioning, each torsion spring provides stable mechanical return and smooth rotational movement.

To meet different engineering requirements, we offer fully customized solutions, including coil diameter, wire thickness, leg length, leg angle, and torque specifications. Various surface treatments such as nickel plating, zinc plating, passivation, or black oxide are also available to improve corrosion resistance and product durability.

With advanced manufacturing capability and strict quality inspection, our coil torsion springs are widely used in automotive components, electronic devices, mechanical assemblies, hardware fittings, and household appliances. Both prototype samples and large-scale production are supported to ensure reliable supply for global customers.
