Hangzhou precision sheet metal stamping parts communicate with you the precautions for the selection of precision molds

In Hangzhou precision sheet metal stamping parts, the quality of the mold is the prerequisite for qualified stamping. At the same time, the steel used in the mold is an important factor in the mold, so it is particularly important to choose the right steel in the design of the mold. The following Xiaoshuo sorts out a few points for your reference: 1. Wear resistance, when the blank is plastically deformed in the mold cavity, it flows and slides along the surface of the cavity, causing violent friction between the surface of the cavity and the blank. As a result, the mold fails due to wear. Therefore, the wear resistance of the material is one of the basic and important properties of the mold. Hardness is the main factor affecting wear resistance. In general, the higher the hardness of the mold parts, the smaller the amount of wear and the better the wear resistance. In addition, wear resistance is also related to the type, quantity, shape, size and distribution of carbides in the material. 2. Strength and toughness. Most of the working conditions of the mold are very bad, and some often bear greater impact load and cause brittle fracture. In order to prevent the sudden brittle fracture of the mold during work, the mold must have high strength and toughness. The toughness of the mold mainly depends on the carbon content, grain size and organization state of the material. 3. Fatigue fracture performance. In the process of mold work, under the long-term action of cyclic stress, fatigue fracture often occurs. Its forms include impact fatigue fracture, tensile fatigue fracture, contact fatigue fracture, and bending fatigue fracture.
