After the processing of precision hardware stamping parts is completed, it is necessary to inspect the products produced. Some issues that quality personnel should pay attention to are: no flickering, no deformation, unevenness, poor punching, riveting, bad teeth, bending angle, missing materials, misalignment, bad hooks, and no quality issues, such as surface scratches and indentations. These quality issues must be strictly controlled during the stamping process of metal stamping parts to ensure that the quality of the stamping parts is controlled. The best.

In all hardware and steel applications around the world, many are plate types, and over 70% of these metal plates are made from stamped parts. for example

Automatic stamping parts, stamping shrapnel, precision hardware stamping parts, medical metal stamping parts, communication stamping parts, stretching hardware and electronics

The steel plates on the machine are all produced through stamping. In addition, there are household appliances, instruments

Public machines, etc. are also stamped and formed. Precision hardware stamping parts

Before the metal stamping parts enter the press, it is necessary to ensure that the raw materials can smoothly enter the correct stamping position inside the mold. During the processing, you need to pay attention to some details: deformation caused by scattering and other reasons; Rust, excessive placement causing oxidation; Due to oxidation issues caused by fingerprints, these issues need to be strictly handled and controlled during the processing.

In addition, precision hardware stamping parts need to meet their unique rust prevention requirements: factory stamping parts must be guaranteed a 15 day rust prevention time.

Clean up the metal waste generated during the stamping process in a timely manner to avoid mixing with other products or sticking to them.
