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. 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. […]
the merit of the Gas-assisted injection molding—slight warp and distortion of products. […]
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”, […]
Discharge of gas. When the product is cooled until it takes on certain level of rigidity and intensity,, pressure of the gas shall be discharged and recycled, finally open the cavity and eject the product.
Gas dwell, upon the completion of filling in the mold cavity and on the premises that the gas pressure is preserved, the product should be put aside until it gradually cools to compensate shrinkage of the product due to the cooling of materials. […]
I want to say something about Gas injection stage, this stage plays a very significant role in the whole production process in which it directly influences the final quality of a product. […]
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.
