Equipment used for gas-assisted injection molding generally comprises a common injection machine and a gas injection device. […]
as for strictly controlling the temperature of the mold during gas-assisted injection molding cycle, that is because the cooling of fusant in cavity can be kept at an appropriate speed, which shall be of avail for the forming of gas cavity.
as for controlling the pressure for gas injection , it shall be first high then low, wherein at the beginning of injection, […]
as for controlling the time for gas injection, I have more details, premature injection, when the outer layer of fusant has not fully cooled, […]
the technical control of gas-assisted injection molding has it’s own strict requirement, 1) the time and pressure for gas injection should be strictly controlled. 2) temperature of the mold should be strictly controlled.
