Zipper machinery still doesn't understand this? Then you're too far behind

The heating system of the zipper machine is used to heat the barrel and the injection nozzle. The barrel of the injection molding machine generally uses an electric heating ring as a heating device, which is installed outside the barrel and is detected by thermocouples in sections. The heat conducts heat through the cylinder wall to provide a heat source for the plasticization of the material; the zipper machinery still does not understand this? Then you are too far behind.

The working principle of the zipper machine is similar to that of a syringe for injection. The process in which the plastic in the state is injected into the closed mold cavity, and the product is obtained after the curing and shaping process inside the zipper machine.

The working principle of injection molding of zipper machinery is a cycle process, each cycle mainly includes: quantitative feeding - melt plasticization - pressure injection - mold filling and cooling - mold opening Pull pieces. After the plastic part is pulled out, the mold is closed again for the next cycle.

The operation items of zipper machinery include 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 molding process of the general screw zipper machine is as follows: first, the granular or powdery plastic is added into the barrel, and the plastic is made by the rotation of the screw and the heating of the outer wall of the barrel. molten state.

Then the zipper machine closes the mold and moves the injection seat forward to make the nozzle close to the gate of the mold, and then inject pressure oil into the injection cylinder to advance the screw , so that the molten material is injected into the closed mold with low temperature at high pressure and fast speed.

The above is the working principle of zipper machinery, I hope to help you. In addition, zipper machines are widely used in building materials, chemicals, mining, metallurgy, electric power, grain and oil processing, machinery, transportation, ports and transportation industries. Fu type chain conveyor utilizes the characteristics of internal friction and side pressure of bulk materials to ensure the stable state between material layers, and forms a continuous overall flow under the action of the conveyor chain.
