Our requirements for products are gradually becoming higher, which is full of challenges for manufacturers of precision parts processing. At present, the number and types of processing by manufacturers are increasing. In addition, whether the parts meet the needs of the market is also a key consideration. problem. So what are the standards that manufacturers should meet for processing precision parts?
1. Must have fatigue resistance
The mold is heated and cooled repeatedly in the working state. Under the action of variable stress, pressure, and tension, it will cause peeling and cracking of the product surface, thereby increasing friction, hindering deformation and plasticity, and reducing dimensional accuracy. As a result, mold failure is caused. Cold and heat fatigue is the main form of mold failure. Therefore, precision parts must be resistant to cold and heat fatigue.
2. Be strong and resilient
Since the working conditions of parts processing are mostly very bad, the parts will be subjected to various impact loads and brittle fracture will occur. Therefore, the parts need to have higher strength and toughness. It depends on whether the material contains carbon content, grain size and organization state. Bending fatigue fracture may occur in the working process of accessories, and whether it breaks or not depends on the content of inclusions in the material of its strength, toughness, and hardness.
3. High temperature performance
When the working temperature of the mold is high, the strength and hardness of the parts will decrease, leading to early wear or deformation. At this time, the material should have high tempering stability to ensure high hardness and strength at high temperatures.
