Causes and Prevention of Scrap Cold Stamping Parts

Reasons for producing scrap stamping parts:

1. The quality of raw materials for stamping parts is inferior

2. Improper installation, adjustment and use of die

3. Due to long-term use of the die, the gap changes or the working parts and guide parts wear out

4. Due to the impact and vibration of the die for too long, the fastening parts are loose, and the installation positions of the die are changed

5. The operator did not feed the strip correctly along the positioning or did not feed the material according to a certain gap

6. The operation is wrong, and the operation is not carried out in accordance with the operating rules (Guide: Reasons for the production of scrap stamping parts)

Main measures to prevent waste:

1. The raw materials must comply with the specified technical conditions (strictly check the specifications and grades of the raw materials, and conduct laboratory inspections on the workpieces with high dimensional accuracy and surface quality requirements under conditions.)

2. All links stipulated in the process regulations should be fully and strictly abided by;

3. The press and die and other tooling equipment used should be guaranteed to work under normal working conditions;

4. A strict inspection system is established in the production process. The first stamping parts must be fully inspected, and production can only be put into production after the inspection is qualified. At the same time, the inspection should be strengthened to deal with accidents in time;

5. Adhere to the civilized production system, such as the transfer of workpieces and blanks must use appropriate workstations, otherwise the surface of the workpiece will be crushed and scratched and the surface quality of the workpiece will be affected;

6. During the stamping process, the mold cavity should be kept clean, and the orderly processed workpieces should be arranged neatly in the workplace.
