How to deal with the surface of die spring

The surface of spring is identified by various paint layers, such as yellow paint for light and small loads, blue paint for light loads, red paint for medium loads and coffee paint for very heavy loads. Performance analysis: good paint layer for spring surface treatment can kill two birds with one stone, and color can be used to identify various technical parameters, which is convenient for industrial production and operation, and makes the surface of spring smooth The anti-corrosion performance can be better guaranteed.

At present, there are mainly some fixed technical requirements, such as using imported materials to reach the foreign level, but there is a significant gap in the surface treatment effect of the whole spring. Generally, manual painting is used in China, which may cause sagging, leakage, poor combination and poor rust prevention.

Due to the limitations of the process itself, a large number of products need to be repainted. Electrophoretic paint is used in foreign countries. In the water-soluble paint tank, the workpiece is used as the cathode, and a certain voltage and time are applied to form a paint layer with uniform thickness on all surfaces of the spring, which can be cleaned and dried. Its appearance is clean and bright, no particles, no bottom exposure, adhesion is not easy to fall off, hardness is good, 3-4h, if the use of the UK LVH company polyurethane cathodic electrophoretic paint, its softness is quite good. The operating environment has no strong solvent smell, less air pollution, and the wastewater treatment and discharge process is simple. As long as the pH is adjusted to settle the resin of electrophoretic paint, and then the water is discharged.
