Silicon Nitride Ceramic:
Magnesium alloy is a metal with high specific strength, good rigidity, and strong electromagnetic interface protection performance. Its application prospects in electronics, automobiles and other industries are very promising, and it has a tendency to replace traditional iron alloys, aluminum alloys, and even plastic materials. At present, the magnesium alloy parts used in automobiles include instrument panels, seat frames, engine covers, etc. Magnesium alloy pipe parts are also widely used in cutting-edge industrial fields such as airplanes, missiles, and spacecraft. However, the close-packed hexagonal lattice structure of magnesium alloy determines that it cannot be stamped and formed at room temperature. Now people have developed a mold that combines heating and forming to stamp and form magnesium alloy products. The product forming process is as follows: during the lowering of the punch slide, the upper die and the lower die are clamped to heat the material, and then the material is formed in an appropriate motion mode. This method is also suitable for the connection of molded products and the composite molding of various products in a press. Many difficult-to-form materials, such as magnesium alloys, titanium alloys and other products, can be stamped and formed by this method. Because this kind of punching requires the punch slider to have a pause function during the descending process, in order to provide time for heating the material, a new concept of punching machine --- CNC crankshaft servo motor punching machine was developed, which can also be used in punching Compound processing including tapping, riveting and other processes is realized in the mold, which greatly expands the range of stamping processing and lays a solid foundation for the wide application of magnesium alloys in the plastic processing industry.
properties:
