In the hardware processing industry, metal parts, especially those processed through stamping, stretching, and other techniques, are prone to cracking problems. This not only affects the aesthetics of the product, but also directly affects its performance and safety. It is essential to take effective preventive measures during the production process to ensure the quality of hardware products.

1、 Selecting high-quality materials: Choosing materials with mechanical properties that meet the requirements as raw materials for hardware can effectively reduce the risk of cracking during the stretching process.

2、 Reasonable design of product structure: Scientific and reasonable structural design of products can reduce stress concentration and avoid cracking.

3、 Optimize mold design and manufacturing accuracy: Improve the design level and processing accuracy of molds to ensure uniform force distribution on parts.

4、 Properly control processing parameters such as speed, temperature, lubrication conditions, etc. to prevent material brittleness and fracture caused by local overheating or improper cooling.

5、 Adopting appropriate surface treatment techniques, such as sandblasting, polishing, or electroplating, to improve the surface quality of hardware components and increase their strength and toughness.

6、 Strengthen quality management: Strictly implement testing standards, promptly eliminate non-conforming products, and ensure that every product leaving the factory reaches its best condition.

In summary, comprehensive prevention and control measures from multiple aspects are necessary to better address the potential issues that may arise after stretching hardware components, thereby improving the technical level of the entire industry.
