Plastic extrusion and film production are among the most common applications for industrial chill rollers. In these production processes, plastic materials are usually extruded by heating and then need to be quickly cooled before forming and final shaping to ensure a smooth surface and uniform thickness of the product.

If the roller surface is not clean enough or there are pollutants such as oxide layer and oil before electroplating, it is difficult for the chrome layer to firmly bond with the substrate. In this case, the chrome layer of the chrome plated roller is prone to shedding during use.

The high hardness of the chrome plating layer enables it to maintain a good surface state when facing high-intensity friction, and it is not easy to be worn or scratched. Even after long-term use, the surface of the chrome plated roller can still remain smooth and uniform.

Main material types of anilox roller: 1. Metal material ● Aluminum alloy ● Stainless steel 2. Ceramic material ● Aluminum oxide ceramic ● Chromium oxide ceramic 3. Polymer material ● Polyurethane ● Teflon coating

Large ceramic anilox roller: with a diameter greater than 200 mm and a length greater than 1500 mm, it is suitable for industries that require large-area coating, such as large-scale packaging printing, wide-format coating or steel plate coating.

Neoprene roller is made of chloroprene rubber, which is a synthetic rubber produced by α-polymerization with 2-chloro-1,3-butadiene as the main raw material. Neoprene has many excellent physical and chemical properties, making it an ideal material for manufacturing rollers.

Packaging materials and processes often involve various chemicals, such as inks, adhesives and cleaning agents. Polyurethane rollers have strong corrosion resistance to these chemicals and can work for a long time in harsh chemical environments without affecting their physical properties.

If used frequently and the load is too large, the life of ceramic anilox rollers may be shortened to 1-2 years. However, under low load and less use conditions, their service life can reach 5 years or even longer.

The working principle of ceramic anilox roller is mainly reflected in how it transfers liquid evenly to the surface of the substrate through the surface pattern structure. This process involves multiple links to ensure the uniformity, accuracy and stability of the coating.

The effect of vinegar's corrosiveness on the chrome plating layer As a weak acidic substance, acetic acid's main function is to decompose rust by chemically reacting with rust. However, acetic acid itself also has a certain corrosive effect on chrome plating.

The melting point of chromium is 1907°C, which means that the chrome plating can remain solid below this temperature and will not melt. However, in industrial applications, the operating temperature of the roller is usually much lower than this melting point, so the chrome plating rarely faces the risk of melting in actual use.

The surface texture of the ceramic anilox roller is its core function. These tiny grooves control the amount and distribution of ink through their shape, depth and arrangement. Common anilox shapes include honeycomb, straight line, cross line, etc. Different shapes of anilox are suitable for different printing needs.
