Compression spring is a hardware accessory with a spiral geometric shape formed by wire, so its hardening and strengthening operation is more difficult than flat hardware accessories (such as stamping parts). In addition, the hardening effect of the transverse section of the compression spring must be strictly controlled to fully understand the resistance to fatigue fracture of the compression spring after use.
The hardening of pressure springs generally adopts two methods: shot peening hardening and heat treatment hardening.
Shot peening and hardening pressure spring treatment: To process a batch of pressure springs, they can be transported to the shot blasting room by individual conveyor belts. Inside the shot blasting room, there is a set of parallel roller paths that strengthen and roll, driving the pressure spring to rotate forward. This rotation method allows high-speed shot flow to pass through the middle of each coil of the pressure spring and hit the metal surface of the inner coil, which is the area where the stress of the pressure spring is concentrated. Shot peening is a good reinforcement method for suspension springs. After appropriate shot peening, the fatigue life of high stress springs can be increased by more than 4 times.

Flat spiral spring, also known as spring, is a type of spring with one end fixed and the other end acting with torque; Under the action of torque, the spring material undergoes bending elastic deformation, causing the spring to twist in the plane, and the magnitude of its deformation angle is proportional to the torque.
Flat spiral springs are classified according to whether they are in contact with adjacent working components: ① Non contact flat spiral springs, ② Contact type flat spiral springs.
The fixing methods for the fixed end of the flat spiral spring include: ① hinge fixing, ② pin fixing, ③ V-shaped fixation, ④ lining fixation

Twisting springs belong to spiral springs. The end of the torsion spring is fixed to other components, and when the other components rotate around the center of the spring, the spring pulls them back to their initial position, generating torque or rotational force. Twisted springs can store and release angular energy or statically fix a device by rotating the force arm around the central axis of the spring body. These types of springs are usually compact, but there is a pitch between the coils to reduce friction. They generate resistance to rotation or external rotational forces. According to the application requirements, design the rotation direction of the torsion spring (clockwise or counterclockwise) to determine the rotation direction of the spring. Each circle can be tightly wrapped or separated to withstand torsional loads (at right angles to the spring axis). The end of the spring can be wound into a hook shape or a straight torsion arm.
A torsion spring is a mechanical component that works by utilizing elasticity. Generally made of spring steel. Widely used in industries such as computers, electronics, home appliances, cameras, instruments, doors, motorcycles, harvesters, automobiles, etc., it is used to control the movement of mechanical components, mitigate impact or vibration, store energy, and measure the magnitude of force. The main production equipment includes: digital control multifunctional computer spring winding machine, mechanical automatic spring winding machine, spring grinding machine, heat treatment equipment, large-scale hot spring production line, and quality inspection instruments.

constant force springs (or constant torque springs) are named is because their motion force is constantly applied. For applications that require a constant load.
The space requirement of the spring itself is very small, so it can provide a smooth range of motion. Due to the lack of inertia to overcome, constant force springs are very versatile and can be installed on existing hardware to produce a balancing effect. Hengli springs are widely used in the healthcare industry to improve surgical equipment. They are also commonly used in aviation to deploy and retract aircraft doors and effectively balance aircraft windows.
Of course, you will also find constant force springs in many daily applications, such as door closers, hair dryers, fitness equipment, electric motors, cabinet furniture components, and so on.
The load of a constant force spring is determined by the width and thickness of the material, as well as the diameter of the coil. Tight entanglement works in a linear motion mode, not following Hooke's law (F=kX), but continuously generates force during its deflection process. These springs provide a smooth range of motion and constant load when extended or retracted. Hengli springs can be installed in various ways and can also be partially or fully extended. Due to the lack of restrictions on extension speed and acceleration, they can be used for a range of applications.

Metal shrapnel belongs to metal stamping parts and is a mechanical spring component that works by utilizing elasticity. Hardware shrapnel is generally made of metal shrapnel steel. Used to control the movement of mechanical components, mitigate impact or vibration, store energy, measure the magnitude of force, etc., widely used in machines and instruments. The types of hardware shrapnel are complex and diverse. shrapnel manufacturers classify them by shape, mainly including spiral hardware shrapnel, spiral hardware shrapnel, board hardware shrapnel, etc.
Spiral metal shrapnel, also known as twisted metal shrapnel, is a metal shrapnel that undergoes twisting deformation, and the working part is also tightly wound into a spiral shape. The end structure of the twisted metal spring piece is processed into various shapes of twisted arms, rather than hooks. Twisting spring plates are commonly used in balancing mechanisms in machinery, and are widely used in industrial production such as automobiles, machine tools, and electrical appliances.
The copper components inside household sockets are key components that ensure smooth current flow and reduce heat generation. High quality household sockets are made of high-quality copper components, which are resistant to oxidation, have strong toughness, have thick copper sheets, and require minimal riveting. These are the four major indicators for the quality of copper components in sockets.
