Put the label into the forming mold, and after the plastic product is injected or extruded in the forming mold, the label can be combined with the plastic product. This is the method of in-mold molding.

However, to put the label into the forming mold, before that, there was Taiwan Announcement No. 538956 "Suction Transfer Unit of Plastic Film Labeling Machine", in which the case is to set a vacuum suction channel on the body, vacuum suction The channel generates a vacuum through a vacuum generator, and after the main body contacts the suction tank, the label can be sucked and sent into the molding mold of the plastic product.

However, this case only focuses on the adsorption of the label, and does not actually solve the problem that the label enters the forming mold. It may be due to the electrostatic effect of the vacuum generator or the main body. When the main body leaves the forming mold, the label will be taken away or deviate from the forming mold. Molds, resulting in unstable bonding between plastic products and labels, and poor yield of finished products.
