Repair Technology Of Printing Offset Cylinder

　　 printing Roller repair technology without disassembly:

This is a kind of repair technology for printing machine drum developed according to the actual characteristics of printing machine drum, such as high precision, difficult disassembly, corrosion prevention, wear resistance, etc. This technology can completely repair the corrosion and wear at both ends of the drum, the nip, the support tip, and the foreign matter scratch of the drum without disassembling and repairing the printing machine drum.

The outstanding special points of its process:

There is no need to disassemble during repair, no temperature rise, no deformation, no external force, and the original accuracy remains unchanged.

All materials for repair are new nickel based materials developed exclusively, with corrosion resistance and wear resistance far higher than that of raw materials, so the service life of the drum after repair is higher than that of new products.

The repair cycle is short, and the repair work can be terminated at any time, and emergency orders can be printed.

For example, wear, crushing and corrosion of mechanical parts such as roller, undercut, support tip, ink roller, plate hole, tooth rack rod, tooth opening plate, cam, splint, tooth plate mandrel, guide rail, etc.

Mechanical parts repair Range:

All kinds of imported and domestic high-precision molds, crankshafts, rolling rollers, pads, printing press rollers, plungers, oil cylinders, oil pumps, hydraulic motors, cylinder liners, chrome plated rods, gear keyways, rotor bearings, bearing positions and other mechanical parts of different materials and shapes are broken, cracked, scratched, worn, sealed and blocked. Flanges, pipes, valves, etc. are sealed and plugged under pressure without stopping.

Mechanical process characteristics:

During the repair of mechanical parts, they are always in the normal temperature state, without deformation, internal stress, annealing and softening; There is no potential impact of breakage and fracture.

No shedding, no hard spots, high bonding strength

The mechanical property of the repaired part is high. The technical requirements of different properties can be met by selecting the same material. The hardness, wear resistance and corrosion resistance of the repaired mechanical parts can exceed the new ones.

　　 technology The outstanding characteristics of are:

During the repair process, the printing cylinder of the printing machine does not need to be disassembled, does not generate temperature, does not deform, and is not subject to external force, and the printing accuracy of the original machine remains unchanged. The materials used for repair are exclusively developed metal repair materials, with corrosion resistance and wear resistance as durable as the original materials.
