If a synthetic label is statically charged, it can adhere to the inside of the mould tool so that it can be incorporated into the moulding. For low volume IML applications, the charge can be applied by hand. For automatic systems, the label can be charged in or before the tool.

Temporary Adhesion for In-Mould Labelling - Select a problem:

The 7097 Static Wand in conjunction with an IONFIX Compact Generator provides instant manual adhesion of labels. The operator puts the label in the mould, holds the wand about 50 mm from the label and momentarily presses the power button. The label adheres to the mould ready for mould closure and injection.

The label is held so that it passes through a charging station on the way to the tool. Passing through the electric field between a static generator and an earth, the label acquires a static charge. Often, 7081 Generator bars are used to wrap the label around a former for inserting into the mould by a robot.

Typically, an insulated robot arm delivers the label into the mould where a brief static charge provides the temporary adhesion. This solution can require a little engineering to incorporate items from the IONFIX IML Accessories range but does provide more powerful adhesion.
