COATING BLADE

The coating blade is a core component of coating equipment. HM coating blades utilize a high-quality carbon steel substrate with a Silicon Carbide (SiC) thermal spray coating on the edge. This treatment significantly extends the blade’s service life while the precision-engineered edge structure enables meticulous control over coating thickness and uniformity.

HM offers a comprehensive range of specifications, including various thicknesses, widths, and bevel angles, making our products compatible with coatings of diverse viscosities. Widely utilized in industries such as papermaking, film, non-woven fabrics, and printing, our blades combine excellent wear and corrosion resistance. They ensure a smooth, even finish, providing a reliable guarantee for coating quality and production stability.
