Torsion Springs - Product Detail Description

1. Product Overview & Function

Torsion springs are a vital mechanical component designed to exert rotational force (torque) or store angular energy. When twisted along their axis, they provide a counteracting force proportional to the applied rotation. This makes them ideal for applications requiring closing, opening, ejection, or rotational counterbalancing. You'll commonly find them in hinges, clamps, levers, and a wide array of automotive, industrial, and consumer products.

2. Key Features & Advantages

• Precise Torque Delivery: Engineered to provide consistent and reliable rotational force for accurate operation.

• Durable Construction: Manufactured from high-quality materials (such as music wire, stainless steel, or oil-tempered wire) for excellent fatigue resistance and long service life.

• Customizable Design: Available in a vast range of sizes, wire diameters, leg configurations (straight, hooked, hinged, etc.), and coil directions (left or right-hand wind) to meet exact specifications.

• Optimized Performance: Springs can be designed to operate within specific angular deflections, ensuring optimal performance for your unique application.

• Rigorous Quality Control: Every spring undergoes stringent testing to ensure it meets required torque values, load rates, and dimensional tolerances.

3. Technical Specifications (Customizable)

• Materials: Music Wire (SWP-A), Stainless Steel (302/304/316), Oil-Tempered Wire, Chrome Silicon, Chrome Vanadium, Phosphor Bronze, or other special alloys.

• Wire Diameter: Range from miniature springs (e.g., 0.5mm) to heavy-duty designs (e.g., 10mm+).

• Coil Diameter: From a few millimeters to over 100mm.

• Number of Coils: As required.

• Leg Styles & Configuration: Fully customizable - straight torsion, short hook, long hook, hinge, loop, or special bends. Legs can be tangential, radial, or axial.

• Finish/Coating: Optional finishes such as zinc plating, powder coating, electropolishing, or passivation for enhanced corrosion resistance and appearance.
