What should I pay attention to when purchasing a corona roller?
Different materials have different performance requirements for corona rollers. For example, plastic films require higher surface energy, while metal foils require higher cleaning effects. Therefore, before purchasing a corona roller, it is necessary to accurately understand the types of materials that are mainly processed on the company's production line.

What are the surface treatment methods for industrial rubber roller?
Vulcanization is the most common way of surface treatment for industrial rubber rollers. It forms a cross-linked structure by heating the rubber to a certain temperature and adding sulfur, thereby enhancing the hardness, heat resistance and wear resistance of the rubber.

What is the surface of a ceramic anilox roller?
The surface of ceramic anilox roller is usually made of highly wear-resistant ceramic materials, the most common of which include aluminum oxide (Al₂O₃), chromium oxide (Cr₂O₃) and silicon carbide (SiC). These ceramic materials have extremely high hardness and corrosion resistance, and can withstand various harsh working environments.

How does the corona roller work?
Corona roller is a device that uses high voltage to generate corona discharge on the surface of materials, thereby changing the surface properties of materials to enhance their adhesion. It is one of the key components of the corona treatment system, and together with high-voltage power supply, treatment electrode and other components, it constitutes a complete working system.

How to choose the cooling medium for industrial cooling roller?
Water is one of the most common cooling media. Because of its high heat capacity and thermal conductivity, it has been widely used in cooling roller systems. Water has high thermal conductivity efficiency and can quickly take away heat, which is suitable for most industrial scenarios that require large-scale cooling.
How does the porosity of industrial ceramic anilox roller affect ink transfer?

How does the porosity of industrial ceramic anilox roller affect ink transfer?
Porosity directly determines how much ink a ceramic anilox roller can store. Higher porosity usually means that the roller surface has more ink storage space and can therefore store more ink. This is crucial for the uniformity and stability of ink transfer, especially when printing on large areas or at high speeds.
What is the ratio of anilox roller to plate screen count?
06-03
/ 2025
What is the ratio of anilox roller to plate screen count?
In the printing process, the ratio between the screen count of the anilox roller and the screen count of the printing plate directly affects the transfer efficiency of the ink and the quality of the printed product. The common rule of thumb is: the screen count of the anilox roller should be 4 to 6 times the screen count of the printing plate.
