The purpose of corona treatment is to optimise the adhesion properties on polymer-based materials. The low surface energy of polymer-based substrates often leads to poor adhesion of inks, glues and coatings which by nature present significantly high surface energies. To obtain optimum adhesion, it is crucial that the surface energy of the substrate is equal or higher than the surface energy of the material to be applied to the polymer.

NeedleTEC offers a cost-effective method for optimising the adhesion properties of UV adhesive onto plastic needle hubs made from low surface energy polymers like PP, PS and others.

Corona treatment is the answer to the bonding and leakage problems in the production process of needle hubs.

NeedleTEC corona treaters can be installed in any high speed assembling lines. The system includes a high frequency generator, high voltage transformers, needle electrodes and ozone filters.
