EPDM door seals perform two important functions: they act as weatherstrips and reduce the noise level perceived in the vehicle interior. Automobile door seals require specialty surface finishes to make sure that dirt particles will not adhere to them. However, getting a functional coating (anti-friction or flock coating) to adhere during the extrusion process is no easy task.
In the past, EPDM profiles had to be roughened continuously by means of rotating wire brushes – a complicated process with unpredictable results.
EPDM profiles for the automobile industry are pretreated with Openair-Plasma® before painting or flocking at Hutchinson in Aachen, Germany. The advantages: scrap reduction, increased production, and the highest process safety reliability.
New Research and Testing Equipment for Highly Technical Surface Treatment
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.
Comprehensive Process Control for Openair-Plasma Systems
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.
Plasma Instead of Chemicals – Using Openair-Plasma to reduce VOC Emissions
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.
