In the roller coating machine, the roller is a key component that directly contacts the painting and the object to be coated. Its material and performance directly determine the coating quality and the service life of the equipment. Ceramic rollers are a type of high-performance roller commonly used in high-end roller coating machines.

Ceramic roller coating machine is not made of ordinary ceramics but are composite rollers formed by coating a layer of chromium oxide (Cr₂O₃) on the surface.Chromium oxide ceramics have a relatively high hardness, which can significantly enhance the hardness of the ceramic coating, making it less prone to wear during use. In addition, chromium oxide has excellent chemical stability and a longer service life.
Ceramic rollers also have excellent adhesion and transferability, which can achieve the best adhesion and transferability to the coating. This means that the ceramic roller coating machine can well "grasp" a certain amount of paint and evenly transfer it onto the object to be coated.However, the cost of ceramic rollers is very high because of their complex manufacturing process, which leads to their cost being higher than that of ordinary rubber rollers.The nature of ceramics is brittle and they are afraid of violent impacts and bumps. Once there is a crack, it cannot be repaired. Extra care is needed during installation, disassembly and cleaning.

If the paint contains high-hardness and highly corrosive solvents, ceramic rollers should be given priority. Or for manufacturers with extremely high requirements for coating thickness accuracy and consistency, ceramic rollers are the best choice.Although ceramic rollers are expensive, they have a long service life, stable coating quality and extremely low maintenance frequency, making them particularly suitable for production lines with extremely high quality requirements.Through our long-term investigation, we have found that an increasing number of customers are choosing ceramic roller coating machine.
