the various tools and products used in our daily production and life, ranging from the base of the machine tool and the body shell, as small as a embryo head screw, button and the shell of various household appliances, are all closely related to the mold. the shape of the mold determines the appearance of these products, and the processing quality and precision of the mold also determines the quality of these products. because of the different materials, appearance, specifications and uses of various products, molds are divided into non-plastic molds such as casting molds, forging molds, die-casting molds, and stamping molds, as well as plastic molds.
there are a wide range of 2022卡塔尔世界杯正赛 products. my country has gradually become a major 2022卡塔尔世界杯正赛 processing country and a major export country in the world, and has become one of the worlds major 2022卡塔尔世界杯正赛 production countries, with a broad market and consumption potential.
how is the metal mold industry defined? the various tools and products used in our daily production and life, ranging from the base of the machine tool, the body shell, to a small screw, button and the shell of various household appliances, are all closely related to the mold.
when we buy stamping parts in our daily life, we can first observe whether there are abnormal appearances on the appearance of stamping parts, or whether there are defects in the products. stamping refers to a forming method in which external force is applied to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation of the stamping parts, so as to obtain the required shape and size of the workpiece
die refers to the tool that turns the blank into a part with a specific shape and size under the action of external force. it is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting, and engineering plastics and rubber , ceramics and other products in the compression molding or injection molding processing. the mold has a specific contour or inner cavity shape, and the contour shape with a cutting edge can be used to separate the blank according to the contour shape (punching).
when some molds, such as plastic molds, are in operation, due to the presence of chlorine and fluorine in the plastic, strong corrosive gases such as hci and hf will be resolved after heating, which will erode the surface of the mold cavity, increase its surface roughness, and increase wear failure.
mold plays an extremely important role in modern industry, and its quality directly determines the quality of the product. improving the service life and accuracy of molds and shortening the manufacturing cycle of molds are technical problems that many companies urgently need to solve. however, in the process of mold use, there are often problems such as collapse, deformation, wear, and even breakage that need to be repaired.
