Wire forming
Wire forming is a process for manufacturing springs and other wire products.The process involves passing a wire (or other formable material) through a series of dies or mechanical devices to gradually bend or twist it into the desired geometry.

Why choose wire forming
Wire forming technology is widely used in various industrial manufacturing fields, ranging from precision instruments to heavy machinery, due to its high efficiency, precision and cost-effectiveness.
Efficient production
The automated production process greatly improves production speed and output.
Stable quality
Machine control ensures product consistency and reliability.
Cost saving
Large-scale production reduces unit cost, and one-time forming reduces subsequent processing links.
Safe and reliable
built-in safety mechanisms and CNC systems to ensure the safety of operators.
Wire forming process
This process involves gradually bending or twisting metal wire (or other formable materials) into the required geometric shape through a series of dies or mechanical devices.
Material selection
Select the appropriate material, such as high carbon steel, stainless steel, copper alloy or special alloy, according to the application requirements of the spring to ensure that the spring has the required elasticity, strength and corrosion resistance.
Wire forming machine operation
The wire passes through a series of precision dies or guide wheels, the shape of the die determines the final geometry of the spring. The machine can operate continuously or in steps, each step may include winding, twisting, compression or stretching.
Wire pretreatment
The wire may need to go through pretreatment steps such as cleaning, annealing, oiling, etc. to remove surface impurities, improve plasticity, and reduce the risk of breakage during the forming process.
End treatment
The ends of the formed spring may need processing, such as flat ends, hook rings, grinding or welding, etc., to facilitate assembly or enhance the reliability of the connection.
Cold forming or hot forming
Cold forming: Bending or twisting the wire directly at room temperature is the most common method of spring manufacturing. It uses the plastic deformation of the material and is suitable for most alloy steel springs.
Hot forming: Forming is performed at a temperature above the recrystallization temperature of the material. It is suitable for hard or large-section materials that are difficult to cold form. After forming, heat treatment is usually required again to restore the material properties.
Surface treatment and heat treatment
After forming, the spring may also need surface electroplating spraying or phosphating to improve corrosion resistance. Heat treatment is used to optimize the mechanical properties of the spring.
application industries
Wire forming technology plays an important role in many manufacturing fields with its high efficiency, flexibility and precision, meeting the diverse needs of wire forming components from daily necessities to high-end technology products.
