The effective performance and longevity of such products are dictated by the interaction of their surface with liquid. Traditionally, this relationship has been improved with complex chemical coatings cured at high temperatures, additives introduced during the melt process or chemical dips following an electrical discharge, but there are inherent problems with all of these methods. Plasma technology can treat 3D objects, manufactured from different materials with complex shapes, with a low-cost, universal process. This extends the life of the product, particularly in harsh environments, by vastly improving resistance to oil and liquid.
