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.

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.

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.

Garage door springs & hardware box

Garage door springs are a critical component of the garage door system, primarily designed to counterbalance the door's weight, enabling smooth and effortless opening and closing. By storing and releasing mechanical energy, these springs help maintain balance during operation. There are two main types of garage door springs: Torsion Springs: These balance the door's weight through rotational force (twisting motion). Extension Springs: These work by stretching and contracting to offset the door's weight.

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.

Conical springs

The conical spring is a type of compression spring, often used as a damping component or transmission part to absorb vibrations and transmit power. The conical spring is widely used in heavy-duty vibrating screen suspension systems, automotive suspensions, mechanical instruments, toys, batteries and other electronic products, as well as hardware and plastic molds, thanks to its compact structure and excellent stability, which enable it to withstand heavy loads and provide effective vibration damping.

Die springs

In applications where space is limited and particularly where solid height is restricted, springs designed from rectangular or keystoned wire are often selected. These springs are commonly referred to as die springs. Springs made from rectangular wire, with the width of the rectangle perpendicular to the spring axis, store more energy in a smaller space than equivalent round wire springs.\nEven though stress distribution around the rectangular cross section is not as uniform as the round wire section, the energy storage capacity is higher because more material can be incorporated into the allocated space. Rectangular wire is more costly than round wire, but less costly than keystoned wire. Keystoned wire is processed specially so that deformation during spring winding or coiling causes the cross section to become approximately rectangular.

Heavy duty springs

Heavy duty springs are compression, extension, or torsion springs with a great amount of force. They have large wire diameters from 1/4\" (inch) to 5\" (inch) in thickness and are required when the spring needs to support a large amount of load in a mechanism.\nHeavy duty compression springs are used in mechanisms that require a great amount of force to be exerted on the spring. You may find heavy duty compression springs in heavy construction machines, agricultural equipment, industrial equipment and oil field equipment.

Special springs

Special springs refer to a type of spring that differs from ordinary springs in terms of shape, material, function, or application. These special springs typically possess unique characteristics and have a wide range of applications.For example: disc springs, tapered coil springs, convex helical compression springs, spiral coil springs, leaf springs, variable-pitch coil springs, and torsion bar springs. These special springs are widely used in various industrial fields, such as mechanical equipment industry, petroleum industry, automotive industry, and aerospace industry.

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?
