(1) Action selection during injection:

Vertical injection molding machine can be separated operation, also can be semi-automatic and automatic operation.

(2) pre-plastic action selection

According to the pre-plastic feeding before and after the injection seat is receding, that is, whether the nozzle leaves the mold, injection molding machine generally has three options. (1) fixed feeding, (2) before feeding, (3) after feeding.

(3) Selection of injection pressure

The injection pressure of the vertical injection molding machine is adjusted by the proportional pressure regulating valve. Under the condition of setting the pressure, the injection pressure is controlled before and after the conversion of the high pressure and low pressure oil circuit, so that the injection products will not be deformed, and the qualified products will be improved.

Vertical injection molding machine ejection action is started by the open mold stop limit switch (or electronic ruler). Operator can according to the need, by adjusting the ejection stroke switch (or electronic ruler scale distance) to achieve. The ejection speed and pressure can also be set digitally in the computer, and the forward and backward distance of the thimble movement is controlled by the stroke switch (or the set position of the electronic ruler), which controls the ejection and die closing system to stabilize the machine.
