Rotogravure Printing Machine Cylinder Rollers

Chrome-plated roller roughing treatment is to do roughen processing on the surface of roller, so as to increase friction coefficient, and to make it fit much closer with strip steel in the process of operation. What’s more, due to the role of chrome-plated roller pits to store gas, which makes a protective gas film formed between the strip steel and the chrome-plated roller, avoid the abrasion of chrome roller to strip steel. Chrome-plated roller roughen processing technology includes: Shot blast texturing, edm burnishing technology, laser roughening, and so on. Hardness and fatigue strength of the roll surface will be developed much better after the shot blast texturing. In the meanwhile, it can help to decrease occurrence of slip between strip steel and chrome-plated roll, so as to avoid strip material abraded.

Rollers Production Process

We copper plated the cylinder so that it was a little larger than the desired final size. 

Next, we polish the copper-plated cylinder to the desired size.

We load the customer's separated artwork into our proprietary software.

We mechanically engrave the cylinder.

The engraved cylinders are then chromium plated. The chrome plating hardens the printing surface.

The gravure cylinders are proofed and inspected. We print them once and then inspect them very carefully to make sure they are perfect.

The proofed rotogravure cylinders are cleaned, then packaged and shipped to the customer.
