Thermal spraying and machining for the paper and film industry.(13)
Our company developed a WC thermal spray coating for winding drums in 1990 and was the first in the world to announce it. This marked the beginning of a series of new thermal spray coatings for paper machines, accumulating a solid track record of contributing to operational efficiency in the paper industry and achieving reductions in maintenance costs. Our thermal spray technology not only provides traditional single functions (wear resistance, corrosion resistance, and surface properties) but also offers more complex and comprehensive functions. In recent years, we have also advanced the application of thermal spraying to film manufacturing machines, where it is used in processes such as stretching that affect film quality.

Thermal spraying and machining for printing-related applications.(2)
In printing machines, there are rolls known as "cylinders" that greatly influence printing performance. These include the impression cylinder, rubber cylinder (blanket cylinder), and plate cylinder, among others. The required functions for the impression cylinder emphasize wear resistance and surface characteristics rather than corrosion resistance. The plate and rubber cylinders, referred to as single cylinders, are covered with a stamp and blanket, which can cause moisture to accumulate in the gaps and corrode the substrate. In the past, there have been cases of using deflective coatings and nickel plating for corrosion resistance, but due to the complex shapes of the substrates, castings have become mainstream. However, the "pores" inherent in castings have highlighted the shortcomings of past surface treatments. Thermal spraying serves to cover these pores and forms the best protective coating to prevent moisture from reaching the substrate.

Thermal spraying and machining for plants (petrochemical and steelmaking)(5)
Kurashiki Bowling Machinery has utilized thermal spraying technology and started as an emergency hospital for the Mizushima complex. We have responded to the needs of customers from one of the world's leading complexes, which operates day and night, by performing repairs within limited timeframes, contributing to the early restoration of operations in various plants, including steel, petroleum refining, petrochemicals, textiles, and power generation.

Thermal spraying and machining for shipbuilding-related applications.(2)
To enhance the output of the engine, which is the power source of the ship, a turbocharger is essential. When considering a voyage from America to Japan, ships equipped with turbochargers achieve a 3% improvement in fuel efficiency. While 3% may seem small, it translates to a reduction of several thousand liters of fuel. Kurashiki Boring Machine Works also engages in thermal spraying and machining for marine equipment. Here, we will introduce the polishing process of the rotor, which is at the core of the turbocharger.

Thermal spraying and machining for the aviation industry(1)
Challenge to the Sky - Humanity has long yearned to fly, and over the centuries, this wish has been fulfilled. Today, relentless research and development continue in pursuit of even higher performance in terms of flight speed, safety, lightweight design, and environmental compatibility. In recent years, aircraft jet engines with a maximum operating temperature of 1,600°C have been put into practical use, leading to increased demands for thermal coatings to protect component parts from harsher environments and ensure their lifespan. Thermal spraying has been certified by aircraft manufacturers such as Boeing and Airbus as a surface treatment technology that serves as an alternative to chrome plating, and from the perspective of environmental resistance, it meets market demands.
