During the In-Mold Labeling (IML)/ Decorating process, a product label must be placed into the mold in a specific location. One of the most efficient methods for accomplishing this operation is via the use of an electrostatic charging system. This system consists of a Static Generator (A) and one or more charging devices, such as Charging Bars (B) or Charging Point Pinners.
By utilizing this equipment to apply an electrostatic charge onto the label, the label can be easily placed onto the mold’s surface. The electrostatic charge applied to the label creates a bonding force that enables the label to adhere to the mold surface, staying in position during the molding process.
In the illustration: The label is picked up, passed over a Charging Bar (B) and placed in the mold. The static charge holds it in position while the mold closes and the process is completed. Upon opening of the mold the label has been fused into the surface of the injection molded object.
