The anilox roller, also called the metering roller, is a key component on a flexographic printing press. Its main function is to transfer ink from the ink tank to the surface of the printing plate during the printing process. It stores ink through tiny pits or meshes engraved on the surface, and then accurately delivers this ink to the printing plate during the printing process.

For chrome-plated stainless steel rollers, although the chrome layer can provide strong protection, the chrome plating is not perfect. Excessive chemical erosion, high temperature and wear of the chrome layer itself may cause the coating to fail, exposing the base material of the stainless steel, causing rust or corrosion.

The high-temperature resistance of cooling rollers is the basis for their stable operation in high-temperature operations. In order to maintain a stable working state, cooling rollers need to withstand long-term thermal shock in high-temperature environments, and their materials must be able to maintain a long service life without deformation or thermal fatigue.

Visual inspection is the most direct and common surface quality detection method. By visually observing the surface of the water quench roller, technicians can initially find obvious defects on the surface, such as cracks, peeling, pores, etc. This method is suitable for rapid screening and can detect some large defects.

The thickness of the industrial chrome plating layer is usually between 20 and 100 microns, and the specific thickness depends on the purpose and working environment of the chrome plated roller. The greater the thickness, the stronger the wear resistance and corrosion resi

● Cell shape: anilox roller cells can have different shapes, such as round, diamond, hexagonal, etc. Different shapes are suitable for different liquid transfer requirements. ● Cell depth: The depth of the cell determines how much liquid it can store. Deep cells have a large storage capacity and are suitable for transferring high-viscosity liquids; shallow cells are suitable for transferring low-viscosity liquids.

Chrome plated roller is a common industrial surface treatment technology that mainly deposits a layer of metal chromium on the surface of the roller through an electroplating process. Mirror roller is a surface treatment technology that uses mechanical polishing and grinding processes to make the surface of industrial rollers extremely smooth.

The classification of industrial water quenching rollers can be distinguished according to multiple standards, mainly including the material, structure, cooling method and application field of the roller body. The following are several common types of water quenching rollers and their main differences:

In the metal processing industry, tungsten carbide coated rollers are mainly used for metal processing, forming, rolling and other processes. During the metal processing process, the equipment needs to withstand high temperatures, large impacts and friction, so the hardness and wear resistance of the rollers are very high. ● Customer groups: steel mills, aluminum plants, copper plants, metal rolling plants, etc.

Stainless steel is a common industrial heating roller material. It has excellent corrosion resistance and high temperature resistance, and is suitable for most industrial heating occasions. Common stainless steel materials include 304 stainless steel and 316 stainless steel.

The purpose of the rough grinding stage is to remove large scratches, oxide layers and other obvious stains on the surface of the industrial chrome plated roller. Use coarser sandpaper (such as 200 mesh or lower) and a polishing machine for preliminary grinding.

The hardness range of hydrogenated nitrile rubber rollers is usually between 50A and 90A. Specifically, hydrogenated nitrile rubber rollers with lower hardness (such as 50A-60A) are mainly used in situations requiring higher elasticity and better adaptability, while hydrogenated nitrile rubber rollers with higher hardness (such as 80A-90A) are suitable for environments with greater pressure and high temperature.
