The plastic injection molding process ([Fig.1]).

- Molded plastic products are produced by heat melting thermoplastic resin with a resin heat melting section ([Fig.2]) of a injection molding machine ([Fig.2]), and high pressure injecting the fluidized plastic into a mold ([Fig.3]), filling the cavities formed inside the mold and cooled to solidify into molded plastic products ([Fig.4]).

- The fixed side mold on the left above ([Fig.3]) is placed with the top side shown in the photo facing down on the movable side mold shown on the right below to form a cavity for melted resin.

- After one cycle of this molding process is completed, the mold top and bottom are separated and the molded plastic part is extracted. There are methods of extraction by manual process and unmanned process using robots.
