Embankment slope protection brick mold should have the following characteristics: ★ wear: blank in the mold cavity plastic degeneration, both along the cavity surface flow again slide, so that the blank between the cavity surface and produce intense friction, leading to mold due to wear and failure. So the basic mold wear resistance, one of the most important performance. Hardness is the resistance of the main factors affecting. In general, the higher the hardness of the mold parts, the smaller the amount of wear, the better the wear resistance. In addition, the wear resistance but also with the type, quantity, shape, size and distribution of materials related carbide. ★ strength and toughness: Die mostly very poor working conditions, some often withstand greater impact loads, resulting in brittle fracture. To prevent mold parts suddenly brittle fracture at work, the mold should have a high strength and toughness. Die toughness depends on the carbon content of the material, grain size and organization of the state. ★ fatigue fracture properties: die working process, in the long-term effects of cyclic stress often leads to fatigue fracture. There are many times in the form of small energy impact fatigue fracture, fatigue fracture contact fatigue fracture tensile and bending fatigue fracture. Fatigue fracture properties of the mold depends on its strength, toughness, hardness, and the content of the material inclusions. Baoding in Hebei mold promise: Baoding Ji Suosheng producing plastic molds are used in large-scale automatic plastic mold equipment to ensure product specifications plastic mold, size small error. 100% pure original package material manufacturing, mold durable, turnover more than 200 times.
