Openair® Plasma pretreatment – for reliable coating and flock coating of EPDM profiles
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.
the past, EPDM profiles had to be roughened continuously by means of
rotating wire brushes – a complicated process with unpredictable
Because of its distinct advantages, plasma pretreatment of EPDM profiles has rapidly become the state of the art in the automotive industry:
- High productivity due to fewer rejects
- 100% process monitoring with the plasma control system
- Robust system technology 24/7, high availability (>99.5%)
- Rapid set-up: simple, reproducible arrangement of plasma jets relative to the profile geometry
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.
