Corrugated board production is a complex process that requires precision and high-quality materials. One vital component in this process is the rolls used to make the corrugated cardboard. Chrome plated rolls have long been the industry standard, but tungsten carbide coated rolls are rapidly becoming the preferred choice due to their superior wear resistance and longer life span. However, this does not come without its challenges.
While tungsten carbide coated rolls offer significant benefits compared to chrome plated rolls, the rough surface, uneven coating thickness, and weak adhesion strength of the coating can result in a range of problems. Blistering boards, fractured boards, and serious chip-offs are just a few of the issues that can arise when using poorly coated tungsten carbide rolls.
SRC Corporation has developed a patented thermal spray method that addresses these issues by improving the adhesion strength of the tungsten coating layer and enhancing the wear resistance of the coating. The use of finer powder reduces surface roughness, and the grinding process removes any sharp edges from the coating, allowing for the lowest coefficient of friction possible.
After grinding, the thickness of the coating is uniform, and the blistering board problem is solved, leading to improved printing quality. The result is a superior product that has significant benefits over traditional chrome plated rolls. Chromium carbide coating grinding and tungsten carbide coated rolls are the perfect combination to ensure the highest quality corrugated cardboard products.
When it comes to producing high-quality corrugated board, choosing the right rolls is critical. The advantages that tungsten carbide coated rolls offer over chrome plated rolls are significant, but they are not without challenges. The patented thermal spray method developed by SRC Corporation addresses these challenges head-on by improving the adhesion strength of the coating layer, enhancing wear resistance, and solving problems such as blistering boards and fractured boards. The combination of chromium carbide coating grinding and tungsten carbide coated rolls provides a superior solution that ensures the highest level of printing quality and product longevity.
