Flexo printing roller for 8 color printing machine

Flexo printing roller for 8 color printing machine

1. Application

 

Flexo printing cylinders can be used on most of letterpress, stacked flexo machine,satellite flexo machine,unit flexo machine and combination presses.

 

 

2.Process of flexo printing cylinder

    →Cylinder Initial lathe
    →Initial static equilibrium
    →Shaft over current assembly welding
    →Fine lathe
    →Fine static equilibrium and dynamtic balance
    →Surface treatment: plating,fine grinding,polishing,chroming
    →Packaging

 

3. Features

        5.Advantage

A. High-quality materials for base roller

 

We adopt 45# seamless steel tube or No5 series aluminum as the base roller,which have enough stiffness to make sure the bending deflection is not over the allowable value under heavy pressure.

 

B. Dynamic balance test twice

 

We will do dynamic balance test twice on each cylinders,the radial jumped error will be less than±0.005,which will help do evenly distribution of the inks on the printing material.

 

C.Advanced welding technology

Adopt CO2 protective welding orTIG welding technology at the head of the roller,will assure the welding is continuous and smooth.

D. Heating treatment process

 

This process will increased hardness and to prevent the cylinder from deformation and will assure the geometric accuracy and long service life.

 

 

5.Packaging&shipping     

 

          We  are using plywood cases and wollen blanket to protect the cylinders.And we will also smear anti-rust oil on the cylinder 

          surface which will help prevent surface oxidizing and rusting under moisture.
