Fixed pump injection molding machine can save a lot of energy

Injection Molding Machines have an injection nozzle that is pressed into a recess in the stationary half of the mold. This ensures a continuous flow of plasticized material into the mold. During the molding process, the nozzle maintains the pressure of the melt and keeps the material in a stable state.

The nozzle maintains the pressure of the melt, and it is also used to press the material into the mold cavity. The mold is also equipped with runners that distribute the melt. These runners can determine the dimensions of the molded product. The mold is also equipped with a vertical parting surface. The mold halves are made of heavy steel and are mounted on thick steel tie bars.

The servo/variable frequency drives are a great alternative to a fixed pump Injection Molding Machine. They can be used with high-pressure piston pumps and can save a lot of energy. They can also be used in conjunction with a linear position transducer to ensure the smooth delivery of the plasticized material into the mold cavity. The pressure sensing can be combined with the cylinder speed sensing to allow fine proportional or servovalve control.

The computer control system regulates the speed, back pressure and holding pressure of the plasticized material in the mold. It also controls the charging barrel temperature. PID temperature control ensures the quality of the product. This is also necessary to avoid any warping of the product once it is released from the mold. In addition, the computer can also control the pre-plastic back pressure.
