Air Knife Coating Machine

Introduction

With more than 50 years of expertise in industrial coating technology, Kerone manufactures advanced Air Knife Coating Machines designed to deliver exceptionally uniform, ultra-smooth coatings without any mechanical contact with the substrate. This non-contact coating method uses a high-velocity, precisely metered air jet to level, spread, and control coating thickness, making it ideal for films, paper, foils, textiles, and technical substrates where surface quality and precision are paramount. The system ensures accurate metering even at high speeds and with low-viscosity coating formulations.

The Air Knife coater, likewise called Air Doctor is a case of an old coating system that is still generally utilized and has a part as a part of the coating process. It was broadly used to successively cover the different layers required for photographic movies in light of the fact that it could apply thin layers from low thickness arrangements. Slide and blind coating on account of enhanced quality, higher rates and multilayer ability supplanted it. It is currently generally used to apply pigmented coatings in the paper business and for 100% solids coating, for example, liquid zinc and aluminum in arousing applications A basic process where the coating is connected to the substrate and the abundance is ‘brushed off’ by an effective jet from the air knife. This method is regularly utilized for fluid coatings and is especially boisterous
