The working principle of theinjection molding machine is similar to that of the syringe for injection. It is a technological process of injecting the plastic in the molten state (i.e. viscous flow state) which has been plasticized into the closed mold cavity with the help of the thrust of the screw (or plunger), and obtaining the products after curing and finalizing. Injection molding is a cycle process, each cycle mainly includes: quantitative feeding - melting and plasticizing - pressure injection - mold filling and cooling - mold opening and taking. Take out the plastic part and then close the mold for the next cycle.
There are many kinds of plastic materials used in the process of injection molding, and the types and forms of mold design are also various. In addition, the familiarity of operators with specific injection molding machines and the operating skills of workers are different. At the same time, the objective environment (such as ambient temperature, humidity, air cleanliness) will vary with the seasons Same.
Injection molding machine features:
(1) The computer of the molding machine adopts the computer host chip of imported PLC, matched with LCD screen, software standby fault self diagnosis system and error correction function, which makes the operation more convenient. Its control program is designed in the form of a fool, and can be operated without professional training
(2) It has the first stepless hydraulic frequency modulation technology in China, which solves the adaptability of the molding machine to various materials and blocks, improves the compactness of materials and shortens the molding cycle.
Generally speaking, there are three aspects to evaluate the performance of plastic products:
(1) Appearance quality, including integrity, color and luster;
(2) The accuracy between size and relative position, that is, size accuracy and position accuracy;
(3) Mechanical properties, chemical properties and electrical properties corresponding to the application, i.e. functionality.
