Electrostatic Adhesion for In-Mould Labelling (IML)
If the synthetic label is statically charged, it has the ability to adhere to the inside of the tool so that it can be incorporated into the moulding. Low volume applications can be addressed by hand, whereas there are different ways of charging the label on automatic systems.
Electrostatic Adhesion for In-Mould Labelling (IML) - 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 then adheres to the mould.
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. Depending on the size of the label, a spot-pinner such as the 7090 or a larger item from the 7095 Static Pinner family, powered by an IONFIX Compact Generator, are proven solutions.
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.
