Contact spring welding _ contact spring assembly _ Some treatment methods of contact spring surface:

Sometimes when the finger spring is used for a long time, there will be oil and other dirty things on the surface. Then I will teach you about how to change the finger spring back to a clean appearance:

The contact spring is immersed in A plastic container diluted with clean water metal cleaning agent A(the dilution ratio of cleaning agent A and clean water is about 1:1 or 1:2). The time is appropriate for the surface of the spring to recover the metal color without oil and oxide skin. The soaking time should not be too long. Touch this refers to the surface of the spring is inferior smooth effect cleaner into A has coarse abrasive, spring vibrating finishing machine or hexagonal roller (spring and coarse abrasive volume than the best is 1:3, cleaning agent dosage is 1% - 2%) the weight of the spring with clean water, after grinding and polishing scratches on the surface of the spring, improve the surface of the spring. But the spring with high precision and easy winding is not suitable for this method.

In the ultrasonic equipment, the ratio of cleaning agent and water is about 1:30, and the time is appropriate to restore the metal color with no oil and no oxide skin on the surface of the spring. Remove it and rinse it with clean water, so that the surface of the finger spring can achieve the matte effect.

Put the brightener B with the vibration of the coarse abrasive finishing machine or hexagonal inside the drum (spring with fine abrasive volume ratio of 1:3, the amount of brightener B is 1% - 2%, the weight of the spring, the brighter the longer) after polishing, dry it out with clean water, touch it refers to the surface of the spring, such as nickel plating lights, general won't fade.
