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. […]
fusant injection, the plastic fusant is quantitatively injected into the mold cavity. In this stage, it is very similar with traditional injection molding. […]
you ask too much! Ok! Now I have to tell you more details about a technical process of gas-assisted injection molding. […]
a rough technical process of gas-assisted injection molding is where in high-pressure insert gas is injected into core part of the plastic fusant to form a hollow section and further help pushing fusant flow, thereby achieving injection, dwell as well as cooling.
today you ask me some questions about Gas-assisted injection molding, now I have some information about it at hand. […]
