Water-Assisted Injection Molding Technology Water-assisted injection molding is a new technology developed by IKV based on gas-assisted injection molding technology. Water is used instead of nitrogen to assist the flow of the body. Finally, compressed air is used to press water out of the workpiece. Water-assisted injection molding can significantly reduce molding time and reduce…
Mold Sliding Injection Molding Mold sliding injection molding is a two-step injection molding method developed by Nippon Steel Co., Ltd., which is mainly used for the manufacture of hollow products. The principle is that the hollow product is first divided into two parts, and the two parts are respectively injected to form a semi-finished product,…
Plastic Mold Steels Should Meet The Requirements The working condition of the plastic mold is different from that of the cold die. Generally, it must be operated at 150 °C-200 °C. In addition to being subjected to a certain pressure, it must also withstand the temperature influence. The same mold can have multiple failure modes,…
Plastic Mold Material Selection 1. Working conditions of plastic mold Due to the development of plastics and plastic molding industry, the quality requirements of plastic molds are getting higher and higher, so the failure of plastic molds and its influencing factors have become important research topics. The main working parts of the plastic mold are…
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,…
Metal 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…
Process 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,…
Die 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…
MIG 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…
Flux 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)…
