摘要： The present invention relates to an injection mold, an injection molding machine including the injection mold, and a method of manufacturing an injection-molded product using the injection molding machine. More specifically, the present invention relates to an injection mold including a mold having a mold surface on which one or more deposition layers are laminated, wherein the deposition layer includes a fluororesin homopolymer or polyether ether ketone (PEEK); an injection molding machine including the injection mold; and a method of manufacturing an injection-molded product using the injection molding machine.
According to the present invention, even without special equipment, an injection-molded product having an aesthetically pleasing appearance without surface appearance defects, such as swirl marks, silver streaks, glass fiber (G/F) floating, and weld lines, may be manufactured. In addition, the injection mold of the present invention may be used semi-permanently without replacing parts. Therefore, according to the present invention, manufacturing process time and costs may be reduced, and manufacturing process precision may be improved.
