Advantage of 400 ton molding machine:

1.With special designed plasticizing system, with high efficiency and durability.

2.Simultaneous execution of multiple actions to shorten the molding cycle.

3.The machine is full automatic, safe, efficient and labor-saving.

The working principle of the 400 ton molding machine is similar to that of a syringe for injection. It uses the thrust of the screw (or plunger) to inject the plasticized plastic in the molten state (that is, the viscous state) into the closed mold cavity. , The process of obtaining products after curing and shaping.

Injection molding is a cycle process, each cycle mainly includes: quantitative feeding - melt plasticization - pressure injection - mold filling and cooling - mold opening and taking out. After the plastic parts are taken out, the mold is closed again for the next cycle. Injection molding is a cycle process, each cycle mainly includes: quantitative feeding - melt plasticization - pressure injection - mold filling and cooling - mold opening and taking out, after taking out the plastic parts, the mold is closed again for the next cycle.

400 ton molding machine operation project: The injection molding machine operation project includes three aspects: control keyboard operation, electrical control system operation and hydraulic system operation. The selection of injection process action, feeding action, injection pressure, injection speed, ejection type, temperature monitoring of each section of the barrel, adjustment of injection pressure and back pressure, etc. are carried out respectively.

The general molding process of the screw injection molding machine is as follows: first, the granular or powdery plastic is added into the barrel, and the plastic is melted by the rotation of the screw and the heating of the outer wall of the barrel, and then the machine is closed and the injection seat is moved forward. Make the nozzle close to the gate of the mold, and then pass the pressure oil to the injection cylinder to advance the screw, so that the molten material is injected into the closed mold with a high pressure and a relatively fast speed. Time and pressure are maintained (also known as pressure holding), cooled to solidify and form, and the product can be opened and taken out (the purpose of pressure holding is to prevent the backflow of the molten material in the mold cavity, replenish the material into the mold cavity, and Ensure that the product has a certain density and dimensional tolerance). The basic requirements of injection molding are plasticizing, injection and molding. Plasticization is the premise to realize and ensure the quality of molded products, and in order to meet the requirements of molding, injection must ensure sufficient pressure and speed. At the same time, due to the high injection pressure, a correspondingly high pressure is generated in the mold cavity (the average pressure in the mold cavity is generally between 20-45MPa), so there must be a sufficient clamping force. It can be seen that the injection device and the clamping device are the key parts of the injection molding machine.
