Plastic Injection Molding Process Plastic products, and the molding process is highly automated, and has a wide range of applications in plastic molding. However, with the increasing use of plastic products, people have put forward higher requirements on the precision, shape, function and cost of plastic products. The traditional injection molding process has been difficult…
Gas (Water) Assisted Injection Molding Gas-assisted injection molding is one of the most important developments in injection molding technology since the advent of reciprocating screw injection molding machines. It produces a hollow section inside the injection molded part by high-pressure gas, utilizes the volumetric pressure of the gas, reduces the residual internal stress of the…
Applicability Of Gas Assisted Injection Molding Technology Gas-assisted technology has made it possible to use injection molding for many parts that could not be injection molded by traditional processes. It has been obtained in almost all plastic parts such as automobiles, home appliances, furniture, electronic devices, daily necessities, office automation equipment, and building materials. Wide…
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,…
