In general, injection molding refers to a manufacturing method of molding a product by adding an additive such as a pigment, a stabilizer, a plasticizer, and a filler to a plastic raw material, and then heating the raw material to be injected into a mold in a molten state. Gas may be generated from the molten raw material during the injection molding process. If the gas generated during the melting process is directly injected into the mold, various burn marks, weld lines, bubbles, etc. may occur in the injection molding, thereby causing a defect in the product. As such, when burn marks, weld lines, bubbles, etc. are generated in the product, not only the appearance is bad, but also the strength is weak, which may cause a problem of weakening the impact. In addition, as well as a huge economic loss due to the generation of defective products, as well as the problem of environmental pollution due to the disposal of materials, it is urgent to develop a technology for removing the gas contained in the raw material for injection.

Conventionally, various apparatuses for removing gas from molten resin, which is a raw material for injection, have been developed, but a certain amount of defective products have to be generated because the gas is not completely removed.
