The contact metal spring piece belongs to the metal stamping component, which plays a high-quality switch role between the operator and the product through the conductivity of the metal spring piece.

Regular cleaning of contact hardware shrapnel can extend its service life and reduce production costs. How do you clean contact hardware shrapnel?

There are the following methods for cleaning:

1. Clean the fat, oil, and lubricating oil contamination that comes into contact with hardware shrapnel with a soft cloth or paper, and then use a neutral detergent or ammonia solution or specialized detergent to wash it; Fingerprints, dried with alcohol or organic solvents (ether, benzene) and washed with water after wiping with a soft cloth; Immediately rinse the bleach and seed acid with water, soak in ammonia or neutral carbonated soda water solution, and then wash with neutral detergent or warm water.

2. Welding that comes into contact with metal shrapnel discolors due to heat. Wash with 10% nitric acid or hydrofluoric acid solution, then neutralize with a dilute solution of ammonia water, carbonated soda, and then wash stainless steel springs with water - specifically for washing drugs; Organic carbides are attached and soaked in a hot neutral detergent or ammonia solution, and then washed with a detergent containing weak grinding.

3. Label and film, wipe with warm water and weak detergent; Dust and easy to remove dirt, wash with soap, weak detergent, or warm water; Binder components, using alcohol or organic solutions; Rust caused by surface pollutants in contact with metal shrapnel should be washed with nitric acid (10%) or grinding detergent - excessive rainbow marks caused by the use of specialized cleaning drugs, detergent or oil, and warm water neutral detergent should be used for washing.

The precautions for cleaning contact hardware shrapnel include the following:

1. When washing, please be careful not to scratch the surface and avoid using bleach ingredients, detergent containing abrasives, steel wire balls (brush roller balls), grinding tools, etc. To remove the detergent, rinse the surface with clean water after washing.

2. When cleaning stainless steel products, efforts should be made to minimize surface damage to the stainless steel, making it look more comfortable and comfortable to use.

3. In daily life, we often see that although stainless steel does not rust, the surface still often shows stains. Stainless steel springs are a bit more difficult than ordinary stainless steel, so some small techniques should be used to handle them.
