Stamping

In the production process of stamped parts, common quality problems include the following aspects:

1. Dimensional deviation: In the stamping process, excessive dimensional deviation may occur, resulting in products that cannot be assembled or used correctly. The solutions include timely checking the stamping process, adjusting the jigs and fixtures, as well as occasional dimensional measurements and corrections.

2. Surface Quality Problems: The surface of the stamped parts may have surface quality problems such as pits, scratches, oxidation, discoloration, etc., which affects the aesthetics and durability of the products. Solutions include regular cleaning of the mold, strengthening mold maintenance, reasonable choice of lubricants and surface treatment processes.

3. Fracture or deformation: During the stamping process, punch cracks or deformation may occur, resulting in functional damage to the product. The solutions include optimizing the parameters of the stamping process, strengthening the quality inspection of die steel, improving the stability of the equipment and regular equipment maintenance.

4. Internal quality problems: Since it is impossible to directly observe the internal condition of the stamped parts, internal quality problems, such as internal air holes and impurities, may occur, affecting the strength and service life of the products. Solutions include adopting transparent stamping molds and using non-destructive testing techniques such as ultrasonic and X-ray for internal quality inspection.

5. Plugging and dropping molds: During the stamping process, molds may be plugged or dropped, resulting in unstable product quality or reduced productivity. Solutions include strengthening die cleaning, replacing severely worn die parts regularly, and strengthening die fixing and pressing.

Overall, effective prevention and solution of quality problems in the production of stamped parts requires comprehensive strengthening of process control, mold maintenance and equipment management, improving staff skills and management level, and ensuring that all aspects of the production process are strictly enforced with quality control standards and regulations, in order to improve product quality and production efficiency.
