Features of hardware mold accessories:
1. Wear resistance
When the blank is plastically deformed in the mold cavity, it both flows and slides along the surface of the cavity, causing severe friction between the surface of the cavity and the blank, resulting in the failure of the mold due to wear. Therefore, the wear resistance of the material is one of the most basic and most 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. Strong toughness
Most of the working conditions of the mold are very bad, and some often bear a large impact load, which leads to brittle fracture. In order to prevent sudden brittle fracture of mold parts during operation, the mold must have high strength and toughness. The toughness of the mold mainly depends on the carbon content, grain size and organizational state of the material.

Metal molds are classified according to the nature of the process
(1) The blanking die is a die that separates materials along a closed or open contour. Such as blanking dies, punching dies, cutting dies, incision dies, trimming dies, cutting dies, etc.
(2) The zigzag die is a die that bends and deforms the sheet blank or other blank along a straight line (zigzag line), thereby obtaining a workpiece with a certain viewpoint and shape.
(3) The deep drawing die is a die that makes the sheet blank into an open hollow part, or further changes the shape and size of the hollow part.
(4) The forming mold is a mold that directly imitates the blank or semi-finished workpiece according to the shape of the convex and concave molds, and the material itself only undergoes partial plastic deformation. Such as bulging die, shrinking die, flaring die, rugged forming die, flanging die, shaping die, etc.

Metal molds are classified according to the degree of process combination
(1) A single-process die is a die that only completes one stamping process in one stroke of the press.
(2) The composite mold has only one station. In one stroke of the press, two or more stamping processes are completed together at the same station.
(3) The progressive die (also known as the continuous die) has two or more stations in the feeding direction of the blank. In one stroke of the press, two or two passes are completed at different stations one after another. Dies for the stamping process above.
(4) The transfer mold summarizes the characteristics of the single-process mold and the progressive mold. Using the robot transfer system to complete the rapid transfer of the product in the mold can greatly improve the production efficiency of the product, reduce the production cost of the product, save the cost of materials, and improve the quality of the product. Safe and reliable.
