Headlights are constructed basically from a casing, a reflector and plastic end cap. The demands of up-to-date and multifaceted designs often mean that space for glue joints is greatly restricted. The space remaining requires a secure bond that is impenetrable to water vapor.
With Openair® Plasma it is possible to combine a variety of plastic materials, such as polypropylene and polycarbonate. Plasma activation results in precisely targeted increase in surface tension along with micro-cleaning of area where the glue is to be applied. All common types of adhesives are suitable for the subsequent bonding operations, such as silicone, polyurethane rubber and especially single-component warm melt adhesives with high initial strength.
The ease of integrating Openair® plasma technology in inline processes results in highly efficient process designs as well.
Determining surface tension with dyne inks now
Plasmatreat constantly faces shifting demands as a result of new ideas, regulations, and standards. Customers are increasingly approaching the company with unique and innovative project requests. Consequently, the capacities of the technology and research center will now be expanded to include a class-6 cleanroom.
Plasmatreat supports digitized manufacturing with its Plasma Control Unit (PCU) and makes numerous controls, regulation, and monitoring functions available to ensure consistently high surface-treatment quality and reproducibility.
VOCs occur when solvents and solvent-containing products are used, and they are harmful to the environment. Nevertheless, manufacturing in many industries still involves pre-treating surfaces with primers, bonding agents or other chemicals that release VOCs. With its Openair-Plasma process, Plasmatreat offers an environmentally friendly alternative.
