Papermaking Machinery Industry

The machinery and equipment in the papermaking industry operate under conditions of high speed, high temperature, high pressure, heavy loads, and corrosive media. The wear, scratches, and abrasions on these machines and various rolls, combined with corrosion and high-temperature oxidation, to surface damage that gradually caused component failure. This is a major factor limiting the yield and quality of paper products.

Thermal spraying technology is widely applied to various components in the papermaking industry, including calendar rolls, drying cylinders, sizing rolls, multi-stage rolls, rewind machine rolls, and guide rolls. The preparation of functional coatings for papermaking equipment is a well-established part of our service range, having generated significant economic benefits for the industry over the years.

Our company has extensive experience in processing mirror-finish drying cylinders and various rolls, with mature processes and strong technical capabilities. We enhance the surface smoothness and hardness of equipment, reduce production costs, and improve paper quality.

We also provide reinforcement and repair services for the inner walls of steam boilers, drying cylinders, and drying ovens; surface reinforcement and repair for various root-type components; and repairs for parts such as commercial pumps, axial flow pumps, steam boilers, valves, and mixing shaft seals. Additionally, the surface reinforcement of corrugated rolls can increase hardness to HV1200 after treatment, extending the working life of corrugated rolls to over 40 million meters.
