Plating Non Stick Coatings

Plating Non Stick Coatings

Plating non stick coatings, forms of electroless nickel plating (EN), are a relatively newer concept for plastics injection molding. Some are taking the industry by storm.

Nevertheless, their release properties by some coating service providers are widely documented in an array of industrial applications.

Not to be confused with dry lubrication, plating non stick coatings, for best results, are better associated with properties relating to surface non wetting strength.

Common EN composites in the industry include ‘nickel Teflon’, a co-deposit of 15-25% by volume PTFE (polytetrafluoroethylene). Still, others in metal finishing, through alternative means, integrate both higher PTFE levels and alternative compounds.

Depending on the sticking material’s cohesive and adhesive nature, plating non stick coatings metal finish may be manipulated to enhance release performance. Surface textures or higher micro inch finish, for example, may be helpful factors.

Today, some of the plating non stick coatings integrate ceramic, diamond, boron, or carbide. For applications with extreme abrasion and low surface energy, some of these alternatives look especially promising. Not to mention their improved heat transfer.

Teflon or fluoropolymer-based coatings can offer exceptional non stick performance. But some environments are simply too severe for plastic level toughness. Even those with internal forms of reinforcement, they lack the necessary ‘micro hardness’. For those applications we strongly suggest plating non stick coatings from those most knowledgeable. That way, in many instances, you can be assured long term sustainable release performance.
