Definitions
- the present invention relates to injection molds.
- Injection molding is a method of molding an injection product by putting an injection material melted by applying heat into an injection mold.
- Injection molded products engraved with conventional embossing patterns are mostly applied in a form without post-processing such as painting/plating, and since concealment by post-processing is impossible, the aesthetic problem of staining the surface is a serious problem and needs to be urgently solved. It is a task.
