How to improve the surface quality of metal stampings
With the increasingly fierce competition in the stamping parts market, the quality requirements for metal stamping parts in the market are becoming more and more strict. Due to various reasons such as raw materials and processing procedures, mechanical equipment, etc. in the stamping process, the surface quality problems of metal stamping parts have caused us. It is necessary to carry out effective prevention and treatment, so that the surface quality of metal stamping parts can be effectively controlled,
In the processing of metal stamping parts, the phenomenon of scratches and pad pits cannot be avoided, so preventive measures should be taken before processing, starting with the raw materials and starting from the cutting. Employees are required to conduct visual inspection on the raw materials of metal stamping parts. If scratches or pad pits are found, the staff must notify the relevant personnel to handle the material return.
During the processing of metal stamping parts, scratches and pad pits that occur due to molds and other reasons. The stamping of metal stamping parts is mainly completed by the mold. The quality of the mold is also very important. It is the premise and basis for ensuring the quality of metal stamping parts. For new molds, the mold gap adjustment method is very important. Because the mold gap is small, the roundness error of the processed metal stamping parts is small, but the surface of the parts may be scratched. If the mold gap is large, the roundness error of the processed metal stamping parts is large, but the surface of the parts may be scratched. Because of its small size, we should adjust the stamping gap of the mold carefully.
Before processing the metal stamping parts, the worktable of the stamping die should be inspected. If the table has pits or bumps, sanding treatment should be carried out. At the same time, the worktable of the mold must be clean and free of residual metal shavings and other dirt. ;
The surface quality of metal stamping parts must be strictly controlled from the root cause, so that the surface quality problems of parts can be prevented, and under the budding state, the quality of the metal stamping parts can be controlled and improved in a real sense.
