Precision mold in the process of work essential six big performance

Precision mold in the process of work necessary six 1 performance, wear resistance of billet on precision plastic degeneration in mold cavity, the cavity surface flow and sliding, the cavity surface with a dramatic friction between billet, resulting in mould failure due to wear and tear. So the wear resistance of materials is one of the most basic, the most important performance of mould. Hardness is the main factors influencing the abrasion resistance. Under normal circumstances, the mould parts of hardness is higher, the smaller the amount of wear and tear, abrasion resistance and the better. In addition, abrasion resistance and carbides in the material type, quantity, shape, size and distribution. 2, strong toughness precision mold working conditions are very bad, some often bear greater impact load, which can lead to brittle fracture. Suddenly brittle fracture at work to prevent mold parts, mold with high strength and toughness. Mould toughness mainly depends on the material state of carbon content, grain size and organization. 3, fatigue fracture performance precision mold working process, under the effect of cyclic stress of the long term, often leads to fatigue fracture. Its form has little energy repeated impact fatigue fracture and tensile fatigue fracture contact fatigue fracture and fatigue fracture. Fatigue fracture properties of mold mainly depends on the strength, toughness, hardness, and the content of inclusions in the material. 4, high temperature performance into the job as a precision mold temperature is higher, can make the hardness and strength, cause mould early wear or produce plastic deformation and failure. Because of the mould material should have high tempering stability, resistance to ensure that the mold in the working temperature, has high hardness and strength. 5, cold and hot fatigue resistance of some precision mold in the process of work is in a state of repeated heating and cooling, make the cavity surface tension, pressure stress, the effect of surface crack and spalling, caused by increasing friction, obstacles to plastic deformation, reduces the dimension precision, resulting in mould invalidation. Cold and hot fatigue is one of the main form of hot-work die failure, help the mould should have high resistance to cold and hot fatigue performance. 6, corrosion resistance, some precision mould, such as plastic die at work, because of the elements such as chlorine, fluorine plastics, thermal decomposition after precipitation hci, hf, such as strong erosion gas, erosion surface of mould cavity, increasing its surface roughness, aggravate the wear failure. Dongguan precision electronic technology co. , LTD. , established in January 2008, is a professional design and manufacture of precision stamping die and precision hardware stamping ODM/OEM professional manufacturers.
