Plastic Mold Steel Performance Requirements With the rapid development of the manufacturing industry, plastic molds are indispensable tools in plastic molding processing, and the proportion of total mold production has increased year by year. With the development and continuous production of high-performance plastics, the types of plastic products are increasing. The use continues to expand,…
DetailsMetal Powder Injection Molding Structure The microstructure of the injection molded metal has the following characteristics: (1) High tissue density. Since the sprayed metal droplets are sequentially splashed and impact-deformed, sequentially self-melting and solidifying, it is easy to fully fill and close the pores, so the material structure pores are few and small. (2) The…
DetailsProcess Characteristics Of Metal Powder Injection Molding The process of fabricating the workpiece by the metal powder injection molding process is simple, the production cycle is short, and the metal powder can be directly purchased from the milling factory, eliminating the processes of batching, mixing, pressing and sintering. After injection molding, the workpiece (tool, mold,…
DetailsDie Forging Die forging is divided into hammer forging and press forging. The similarities between the two are: (1) The die forging deformation process can be divided into three stages: the first stage is the squeezing stage, the second stage is the filling stage, and the third stage is the tying stage. (2) The deformation…
DetailsMIG Welding And Carbon Dioxide Gas Shielded Welding 1. Characteristics of molten argon arc welding (1) Like tungsten argon arc welding, it can weld almost all metals, especially for welding aluminum and aluminum alloys, copper alloys and stainless steel. (2) Because the wire is used as the electrode, the current density is large, so the…
DetailsFlux Cored Wire Gas Shielded Welding Flux cored wire gas shielded welding is commonly used to weld carbon steel, low alloy steel, stainless steel, cast iron. 1.Advantage (1) Combined protection of gas and slag, the weld bead is beautifully formed, the arc stability is good, the spatter is small and the particles are fine. (2)…
DetailsExtrusion The blank is subjected to three-direction uneven compressive stress in the closed cavity, and is extruded from the orifice or slit of the mold to reduce the cross-sectional area, and the processing method for forming the desired product is called extrusion. Classification extruded (1) According to the forming temperature, the extrusion is divided into…
DetailsWelding Process 1. Fusion welding: A method of locally heating and melting a surface of a connected object to a liquid and then cooling it into a unit. 2. Pressure welding: The physical effects of friction, diffusion and pressure are used to overcome the unevenness of the two joint surfaces, and the oxide film and…
DetailsSubmerged Arc Welding Submerged arc welding is a method in which an arc is burned under the flux layer for welding, and electrical and mechanical devices are used to feed and move the arc. 1.Basic principle The welding arc is burned between the wire and the workpiece, and the arc heat melts the ends of…
DetailsBrazing 1.Advantage (1) The heating temperature is low, which has little influence on the microstructure and properties of the base metal and is easy to ensure the dimensional accuracy of the weldment. (2) It can realize the connection of dissimilar metals or alloys, metals and non-metals. (3) Some brazing methods can complete dozens or hundreds…
