Features of precision mold processing

　With the continuous development of mold processing, precision mold processing requirements and applications are more and more extensive, people’s requirements for mold seiko is also more stringent, why choose precision mold processing, what are its characteristics?
 
Features of precision mold processing:
 
1, wear resistance:
 
When the blanks are plasticdenized in the mold cavity, they both move and slide along the outside of the cavity, causing a fierce friction between the outside of the cavity and the blank, which causes the mold to take effect due to wear. To be the data of wear resistance is the most fundamental and important function of the mold.
 
Hardness is an important identity that affects wear resistance. As usual, the higher the hardness of the mold machine, the smaller the amount of wear, the better wear resistance. Otherwise, wear resistance is not related to the variety, number, status, macro-detail and dispersion of carbide in the guess.
 
2, strong toughness:
 
Mold things mostly very naughty premise, some often suffer a larger blow load, which in turn leads to brittle break. In order to avoid the mold machine in the event of sudden brittle break, precision hardware mold to have a high strength and toughness. The toughness of the mold depends on the carbon content, grain size and construction status of the data – precision mold manufacturing.
 
3, tired fracture function:
 
Mold things in the process, in the wheel response force of the long-term sense, each cause fatigue fracture. The situation has small energy repeatedly hit tired fracture, stretch fatigue fracture war fatigue fracture and tortuous fatigue fracture. The fatigue fracture function of the mold depends importantly on its strength, toughness, hardness, and content of the inclusions in the guessing.
 
4, low temperature function:
 
When the mold matter temperature is higher, will reduce the hardness and strength, resulting in late mold wear or plastic deformation and effective. Precision metal mold data should have a high anti-fire stability, to cover the mold in the temperature of the matter, with a higher hardness and strength.
