Dongguan touch spring surface treatment method?

The first step: There are three ways to use the contact spring to remove oil and skin oxidation:

1. Dip the contact spring into the 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. In this way, the surface of the finger spring has a matte effect.

2. Cleaning agent A into the coarse abrasive, spring vibration light decoration machine or hexagonal drum (the volume ratio of the spring and coarse abrasive is the best 1:3, cleaning agent dosage for the spring weight of 1%-2%) after grinding and polishing with clean water, the spring surface scratch is no, improve the finish of the spring surface. But the spring with high precision and easy winding is not suitable for this method.

The above two methods can be applied to springs with high precision.

3. 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 without oil on the surface of the spring and without oxidation skin. Remove it with clean water, so that the surface of the finger spring can achieve matte effect.

Step 2: Polish the finger spring:

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 lights, like nickel plating will never fade.
