The tension spring acts as a buffer. Extension spring is an industrial accessory that has functions such as support, buffering, braking, height adjustment, angle adjustment, etc. It consists of the following parts: pressure cylinder, piston rod, piston, sealing guide sleeve, etc. Extension spring is a type of spiral spring that can withstand axial tension. Tension springs are […]

The surface of stainless steel springs can be treated with phosphating, spraying, blackening (bluing), electroplating, etc. At present, after research and development, zinc chromium film has excellent corrosion resistance. The corrosion resistance of chromium coating is 7-10 times that of traditional electroplating coating, and it does not have hydrogen embrittlement caused by electroplating process. And it […]

After compression spring rolling, recrystallization annealing treatment is required to stabilize the geometric shape of the spring and reduce quenching deformation. The recrystallization annealing temperature is 550-650 ℃, followed by air cooling after 1-1.5 hours. A small amount can be carried out in a salt bath furnace, while a large amount can be used to […]

There are many things to pay attention to when cleaning stainless steel springs; Firstly, during cleaning, there should be no scratches on the appearance. It is necessary to prevent the use of ingredients and cleaning solutions containing bleach, steel wire balls (brush roller balls), grinding tools, etc. to get rid of the cleaning solution. After […]
