Stainless steel double torsion springs are precision-engineered springs featuring two torsion coils wound in opposite directions on a single shaft or axis. Made from corrosion-resistant stainless steel alloys, these springs deliver balanced torque and enhanced stability, making them ideal for applications requiring symmetrical rotational force and long-lasting performance in harsh environments.

• Material: Manufactured from stainless steel grades such as 304, 316, or 17-7 PH to provide excellent corrosion resistance and mechanical strength.

• Design: Consists of two torsion springs connected either by a common center leg or shaft, offering opposing rotational forces.

• Performance: Provides increased torque capacity and balanced load distribution compared to single torsion springs.

• Durability: Resistant to fatigue, corrosion, and temperature variations, suitable for demanding industrial applications.

• Customization: Available in various wire diameters, coil sizes, leg lengths, and torsion rates.

A mild steel toy spring is a lightweight, coiled mechanical component made from mild (low carbon) steel wire, specifically designed for use in toys, hobby kits, and light mechanical assemblies. These springs provide elastic movement through compression, extension, or torsion and are optimized for low-stress, cost-sensitive applications.

• Material: Mild steel (low carbon steel, typically AISI 1006–1010)

• Finish: Often zinc-plated or powder-coated to prevent rust

• Wire Diameter: Typically small (e.g., 0.2 mm to 1.5 mm)

• Spring Type: Compression, extension, torsion, or custom wire forms

• Elasticity: Good for light-duty motion and recoil functions

• Cost-Effective: Economical for mass production in consumer products

A spiral torsion spring is a flat, coiled spring made from strip material wound in a spiral shape. It works by exerting a torque or rotary force when twisted, storing mechanical energy in the process. Spiral torsion springs provide precise rotational resistance and are commonly used in applications requiring controlled rotational movement or return mechanisms.

• Design: Flat strip coiled into a tight spiral, delivering torque through angular deflection.

• Material: Typically manufactured from spring steel, stainless steel, or specialized alloys for strength and fatigue resistance.

• Function: Converts rotational motion into stored energy and returns the mechanism to its original position.

• Performance: Offers consistent torque output, durability, and resistance to wear under cyclic loading.

• Sizes: Available in various thicknesses, coil diameters, and torque ratings to suit specific applications.
