Injection molding machine problems about mold
As a injection molding machine,it will face many problems about mold. What does mold EDM mean Mold EDM is EDM. Electric discharge machining is a special machining method that uses the electric erosion effect generated by the pulse discharge between the two electrodes immersed in the working fluid to abate conductive materials. It is also called electric discharge machining or …
some solutions about injection molding machine screw
How does the injection molding machine screw unusual sound slip to do If the screw begins to slip during the preforming phase, the axial motion of the screw stops as the screw continues to rotate. Usually the screw slip will lead to degradation of materials before injection molding.but also short shot, extended processing cycle and other product quality problems. Influence …
Cooling Time of Injection Molded Parts
Calculation of Cooling Time of Plastic Injection Molded Parts. As a injection molding machine,in injection production, the cooling time of plastic injection molded parts accounts for about 80% of the entire injection production cycle. Poor cooling often results in product warpage or surface defects, which affects the dimensional stability of the product. Reasonable arrangement of injection, holding pressure and cooling …

injection molding machine of structure:work, advantages (compared with other ones）
Injection molding is an important industrial method. It is somewhat similar to die casting, but the difference lies in the raw materials used. In die casting, the metals we use require extremely high temperatures to melt, but injection molding is mainly performed on glass, elastomers, and the most common thermoplastic and thermosetting polymers, but this technology has been widely used to make thermoplastic materials. The process is completed by heating the raw material and applying pressure at a specific temperature to inject it into the mold cavity without any change in its chemical composition.
