1. Wear resistance
When plastic degeneration in the mold cavity, the ingredients are moved along the outside of the cavity and slide, so that the outside cavity and the ingredients outside and the ingredients are intense friction, which causes the mold to take effect due to wear. Therefore, the wear resistance of the data is one of the most fundamental and most important functions of the mold. Hardness is an important identity that affects wear resistance. Under the same circumstances, the higher the hardness of the mold, the smaller the wear, and the better the wear resistance. In addition, the abrasion resistance also has nothing to do with the variety, numbers, status, states, fineness and distribution of the carbonizes in Zi Gue.
2. Strong toughness
Most of the premise of molds is very stubborn, and some often suffer from large blow loads, which leads to crispy breaks. In order to prevent the mold from suddenly crispy at the time of things, the precision hardware molds must have higher strength and toughness. The toughness of the mold depends on the carbon content, grain size and structural status of the data-precision mold manufacturing.
3. Fracture machine energy
In the process of mold, the fatigue breaks were broken with the long -term influence of the reincarnation. The situation has a small energy repeatedly cracking down on fatigue breaks, stretching fatigue, fatigue, fatigue, fracture, and twists and turns. The fatigue fracture machine of the mold depends on its strength, toughness, hardness, and the content of debris in the guessing.
4. Low temperature function
When the temperature of the mold is high, the hardness and intensity will be reduced, causing the advanced mold for mold or plastic deformation and effectiveness. Therefore, the precision injection molding mold should have a higher anti -fire stability, and the pipelines have high hardness and intensity at the temperature of the matter.
