Wire forms

Wire forming refers to the process of shaping metal wires (such as steel wire, iron wire, etc.) into specific functional parts or components through bending and forming techniques. Wire-formed products often exhibit spring-like properties and are widely used in various industrial fields and everyday hardware products.

Constant force springs

Constant force springs offer stable tension and retraction capabilities. After undergoing coiling,they can create an uncoiling force. As a result, they find extensive use in various applications,like lifting spring,Electric fan ,computer,display lifting ,etc,

Variable force springs

The variable-force spring is a type of spring that can alter its form and elastic properties in response to changes in external force. Through ingenious design, it achieves dynamic adjustment of elastic force, enabling it to maintain optimal performance under various complex working conditions.

Constant torque force springs

It is a specially designed spring that primarily delivers a consistent torque output between two spools. By storing energy and returning to its natural curvature upon release, it provides a constant torque output on the driven spool.

Power springs

A spring formed by winding flat material into a flat spiral shape, whose working principle is based on elastic deformation and energy storage. Because of their outstanding retracting characteristic, they emerge as the optimal option for wheel reels.

Spiral torsion springs

Spiral torsion springs can be named clock springs or flat torsion springs. Each coil within these springs remains separate from the others. they create linear torsion.Our company manufactures spiral torsion springs available in multiple sizes.

Carbon brush springs

Carbon brush springs, also known as electric motor brush springs, are extensively employed in electric motors. During the operation of an electric motor, they push the carbon brush against the commutator

Spring clips

Spring clip is a part that has the elastic deformation ability through specific processing and molding of the material, produces deformation when it is stressed, and can return to the initial shape after removing the external force, so as to achieve a specific function.

Wave springs

A wave spring is a spring with a wavy or corrugated shape, usually made of metal materials, such as stainless steel, spring steel, etc.It stores and releases energy through the elastic deformation of its wavy structure during stress. When subjected to axial pressure, the wave crest and trough will gradually be compressed, the spring deformation, thereby absorbing external force; When the external force disappears, the spring returns to its original shape with its own elastic restoring force, releasing the stored energy.

Torsion springs

A torsion spring is primarily made of elastic material, usually in the shape of a cylindrical helix. It generates torque or rotational force by twisting the spring, thereby providing power or motion. We offer torsion springs and double torsion springs crafted from wire in multiple sizes.

Compression springs

A compression spring is a type of helical spring designed to withstand axial pressure. It is typically made by coiling metal wire with a constant pitch and fixed wire diameter. Its key characteristic is the ability to provide resistance when subjected to external compressive loads, storing deformation energy through compression.

Extension springs

An extension spring is the spring that sports hooks, eyes and loops that attach to a connecting part. It’s the spring that pulls everything together. We manufacture right- orleft-hand wound springs with plain, hooked,looped, clipped, or specialty ends.

1. Construction & Material • Made of spring steel for durability and tension retention. • Winding cones (at both ends) are die-cast aluminum—one for winding, the other stationary. 2. Color-Coding for Wind Direction • Red cone end = Right-wound spring (winds clockwise when installed on the left side). • Black cone end = Left-wound spring (winds counterclockwise when installed on the right side).(Note: Proper pairing is essential if using dual springs.) 3. Application & Selection Criteria • Designed for heavy garage doors, providing lifting force. • Must be selected based on spring dimensions (wire size, inner diameter, length) rather than door weight alone. • Regular-duty spring with a 12,000-cycle lifespan (typical for residential use; heavy-duty springs last ~20,000+ cycles). 4. Installation & Replacement • Used to replace worn/damaged torsion springs mounted above the garage door on the header. • Safety Warning: Torsion springs store extreme tension; improper handling can cause severe injury. Professional installation is recommended. 5.Additional Considerations • Cycle Life: 12,000 cycles ≈ 7–10 years for average use (open/close 5x/day). • Matching Springs: If replacing one spring in a dual system, ensure the new spring matches the existing one in wind direction, size, and torque. • Tools Needed: Winding bars, vise grips, and a ladder for safe installation. Would you like guidance on measuring an existing spring or determining the correct replacement size?
