Rotogravure Copper plating machine

Rotogravure Copper plating machine: The process flow of cylinder make production: washing → nickel plating → washing → copper plating → washing → grinding → washing → copper polishing → washing → electric engraving → washing → degreasing →washing→ chrome plating → chrome polishing → proofing. Nickel plating mainly enables the copper layer and the gravure cylinder to be well bonded; rotogravure engraving copper plating machine not only covers the defects of the roller, but also shows the working surface for the next process - engraving. Copper is pink, soft and has good ductility. Copper plating of gravure plate roller is very important. The Rotogravure Copper plating machine is very strictly controlled. Any carelessness will cost a lot of time, manpower and material resources to correct the problems. The thickness of the copper layer can change with the changes in the printed product. Generally, the hardness of the surface copper layer is twice that of the base copper layer, so that the surface copper layer can have better cutting characteristics when engraving the surface copper layer. The hardness of the surface copper layer is about Vickers hardness HV200.

Rotogravure Copper plating machine Working principle:

The Auto intaglio copper tank is a key process step in the electroplating gravure process. The surface requirements of the gravure for the copper layer are: a. Smooth and delicate; b. With a certain hardness; c. No sand eyes and impurities are allowed.

Use the gravure copper plating machine to plate a layer of copper on the surface of the plate roller to prepare for electric engraving. The copper plating process is completed by using the more reasonable one of the three copper plating methods: thin copper layer method, Ballard skin method, and thick copper layer method.

Rotogravure Copper plating machine Feature:

1. Copper tank contains an automatic shielding plate to make the copper more uniform.

2. All electrical components are well-known domestic and foreign brands (customizable) to effectively ensure the stability of the current.

3. The carbon brush adopts a spring-type design, and the conductive performance is more stable.

4. The Rotogravure printing cylinder copper tank used in the copper plating process is made of highly conductive material, which can effectively transmit the current to the Rotogravure printing roller.
