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.
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—low injection pressure and locking force, thereby reducing cost for equipment, since gas-assisted injection adopts “ underfeeding injection”, […]
Gas injection, inject high-pressure inert gas such as nitrogen into the core of fusant and the gas enveloped by plastic fusant shall move forward along a direction with minimum resistance and meanwhile push the flowing front of fusant to move further forward unitl the mold cavity is fully filled. […]
fusant injection, the plastic fusant is quantitatively injected into the mold cavity. In this stage, it is very similar with traditional injection molding. […]
the design also maximizes the pipelines inside the mold and thus allows rapidly raising the temperature to the thermo plastic level. […]
the most important thing is that kind of molding method does not need to open the machine and further transport of a molded part in one mold. […]
but that kind of mold with transfer or insert technique has it’s own disadvantages, because it needs precise centering of the pre-molding, […]
here is a mold with transfer or insert technique, it also can mold two-colored materials or two different materials in one mold, […]
