Gas-assisted Injection Molding Equipment
The gas-assisted equipment includes a gas-assisted control part and a nitrogen generator, it is special and seperate system of the injection molding machine, and its only interface with the injection molding machine is the injection signal connection line. After the injection molding machine transmits an injection signal injection start or screw position to the gas-assisted control unit, it starts a gas injection process, and when the next injection process starts, another injection signal is given, and another cycle starts and so on. The gas used in gas-assisted injection molding must be an inert gas (usually nitrogen), the maximum pressure of the gas is 35MPa, and the maximum pressure of the gas can be up to 70MPa, and the nitrogen purity is ≥98%. The gas-assisted control part is a device that controls the gas injection time and pressure, it has a multi-group gas circuit design that can control the gas-assisted production of multiple injection molding machines at the same time, the gas-assisted control part has a gas recovery function to reduce gas as much as possible consumption.
