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 static equilibrium and dynamtic balance
→Surface treatment: plating,fine grinding,polishing,chroming
|Surface Hardness||≥HRC50,with strong corrosion resistance|
|Roughness||≥ Ra0.16, without air hole or groove|
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.
