In Mold Labeling Injection Molding: A Metal Casting Process for Producing Plastic Parts with Labels. In mold labeling injection molding is a metal casting process that uses high pressure to force molten plastic into metal molds that have pre-printed labels or films inside them. The labels or films become part of the plastic part surface, enhancing its appearance and functionality. In mold labeling injection molding has many advantages, such as reducing the material waste and production time, increasing the durability and resistance of labels, and improving the hygiene and safety of products. In mold labeling injection molding can be performed with various materials, such as polypropylene, polystyrene, polyethylene terephthalate, and polyethylene. In mold labeling injection molding can be used for various industries and applications, such as food and beverage, cosmetic and personal care, medical and pharmaceutical, household and industrial, etc .
