Metal stamping china

In stamping china production, appearance defects sometimes occur, such as pinhole damage, crush marks, and scratches. In such cases, equipping the stamping press with a dust blower is quite effective. Regularly cleaning the die and promptly sharpening the punch to keep it sharp and reduce debris generation are also effective methods.

The die surface must be very smooth. During processing, the die surface should be cleaned with a brush. The die surface and worktable should be cleaned regularly. There should be no iron filings or other particulate impurities on the material or die surface. However, a reduced production efficiency and a scrap rate due to poor appearance of precision stamped parts are acceptable.

Precision stamped parts should have their surfaces covered with a protective film to prevent scratches, and no oil or water should be used during processing.
