Manufactured by Mohindra Engineering Company for smooth and uniform paper finishing.
Air Knife Paper Coating Machine manufactured by Mohindra Engineering Company combines precision coating performance with over 35+ years of engineering experience.
Automatic Air Knife Paper Coating Machine Manufacturer in India
In today’s competitive paper converting industry, achieving a perfectly smooth and uniform coated surface is essential for premium-quality paper products. Our Air Knife Paper Coating Machine is engineered to deliver exceptional coating precision by utilizing a controlled high-velocity air stream that accurately removes excess coating material from the paper surface.
The coating is first applied evenly across the substrate, after which the air knife system shears off the surplus coating layer, leaving behind a highly consistent and defect-free finish. This advanced coating technology ensures excellent surface smoothness, improved printability, and superior product appearance.
Designed for demanding industrial applications, the Air Knife Paper Coating Machine is particularly suitable for contour coating, sensitive substrates, and high-viscosity coating formulations. It provides outstanding coating weight control while maintaining high production efficiency and reduced material wastage.
Whether manufacturing specialty papers, coated packaging grades, thermal papers, or release liners, this machine delivers reliable performance and repeatable coating quality throughout long production runs.
