Injection molding machine works similar injections with syringes, it is by means of the screw (or plunger) of thrust, will Plasticised good molten state, vertical injection molding machine (viscous flow state) plastic injection into closed mold cavity, the process to obtain products after curing stereotypes. Injection molding is a cyclical process, with each cycle including: the dosing - melt plasticizing - put pressure injection - filling cooling - Kai mold pickup. Remove the plastic parts again closed mold, the next cycle. Beijing injection molding machine operating items: operating projects include the control keyboard operation, electrical control system operation and hydraulic systems operating three aspects. Respectively injection process operation type selection of the feeding operation, injection pressure, injection speed, the ejector, the monitoring of the temperature of each of the barrel, the injection pressure and the back pressure regulator. Usually a screw type injection molding machine the molding process: First the granular or powdered plastics drum machine, was added so as to very high pressure and a faster speed will melt into a lower temperature within the closed mold, after a certain time and maintain the pressure (also known as the holding pressure), and cooled, the cured molding can open mold to remove the article (holding pressure purpose is to prevent the regurgitation of the melt in the mold cavity, to replenish the material to the mold cavity, as well as ensure universal horizontal injection molding machines permit the article having a certain density and dimensional tolerances). The basic requirement is that of the injection molded plastics, injection and molding. Meanwhile, due to the high injection pressure, in the mold cavity corresponding to generate high pressure (average pressure of the mold cavity is generally between 20 ~ 45MPa) and therefore must have a sufficiently large clamping force. Thus, injection apparatus, and clamping means is? Beijing key components of the injection molding machine. Welcome new and old customers call us: 13833466196
