Plasma cleaning of O-Rings destined for the Automotive Industry
Plasma cleaning of O-Rings
As Europe’s leading industrial services partner, ERIKS provide engineering knowledge and expertise around stand-alone products or services, but more significantly as cohesive, comprehensive, holistic solutions, from a network of Core Competence and Local Service Centres. We were contacted by one local Service Centre in Warrington, Cheshire who were primarily requesting information about plasma treatment of materials & specifically of O-rings.
The team at Henniker tested a selection of O-Rings, destined for an automotive client, using test methods to positively identify the presence of silicone contamination. The batch was cleaned in a low pressure plasma and the test repeated to confirm complete removal of the contamination. We are pleased that we could quickly identify & resolve the issue and now welcome ERIKS as an important client for contract cleaning.
Plasma treatment of O-Rings
Systems and services for PWIS-free plasma cleaning of o-rings and seals.
Many o-ring and seal applications have strict requirements that components are free of any paint wetting impairment substances (PWIS), such as silicones. This applies to painting and coating processes as well as lacquering applications and also some printed circuit board fabrication where critical wire bond tasks are carried out.
Elastomeric materials contain a number of paint wetting impairment substances which are not removed using traditional wet methods alone. Softeners and release agents can migrate from the body of the elastomer to the surface, causing subsequent, costly quality issues. Our plasma cleaning process is developed specifically to ensure PWIS-free components and in which plasma cleaned o-rings conform to the automotive standard (Volkswagen test specification PV 3.10.7).
