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.
hey! Guy, I do know you are right, but please don’t forget gas-assisted injection molding can result in different gloss on product surfaces with and without gas injected, the defect shall need to be decked or covered with patterns.
the merit of the Gas-assisted injection molding—saving plastic materials, since gas in the cavity occupies part of the volume, the product shall become thinner and lighter, generally by 20%--40%.
the merit of the Gas-assisted injection molding–short production cycle. Owing to the small injection volume of gas-assisted injection molding, […]
the merit of the Gas-assisted injection molding–can be used to mold products with diverse wall-thickness
the merit of the Gas-assisted injection molding--can be used to mold products with diverse wall-thickness. using gas-assisted injection molding can achieve uniform filling for products with diverse wall-thickness and, on the premises
the merit of the Gas-assisted injection molding—high surface quality. […]
