◆◇◆ What is HVOF Thermal Spraying ◆◇◆ It stands for High Velocity Oxygen Fuel. It refers to thermal spraying using a high-speed jet flame created by oxygen and fuel. A mixture of high-pressure oxygen and fuel gas is burned in a combustion chamber. The combustion flame is constricted by a nozzle, and the moment it exits into the atmosphere, a rapid gas expansion occurs, resulting in a supersonic jet. The thermal spray material accelerated by high kinetic energy forms a high-density coating with minimal oxidation or compositional changes.

◆◇◆ What is Plasma Spraying ◆◇◆ Plasma spraying is a process that uses a plasma jet generated by a plasma spray gun to heat and accelerate spray materials, bringing them to a molten or near-molten state before spraying them onto a substrate. The diagram illustrates the principle of a plasma spray gun. As shown in the diagram, when a voltage is applied between the cathode and anode, a direct current arc is generated. The working gas (such as argon) supplied from the rear becomes ionized, producing plasma. Then, the spray powder material is fed into the plasma flame using the working gas (such as argon), forming a spray coating.

◆◇◆ What is Wire Thermal Spraying ◆◇◆ It is a thermal spraying method that uses wire-shaped thermal spray materials. To control the temperature of the substrate being sprayed to within 150°C, thermal distortion and degradation of the substrate do not occur. Wire thermal spraying is also called low-temperature buildup spraying and allows for thick buildup. There are "arc spraying" and "wire flame spraying" systems.

• Processing Contract

◆◇◆ What is Localized Thermal Spraying (Rod-Type Frame Spraying) ◆◇◆ Ceramic rods are continuously supplied and melted in an oxygen-acetylene flame, and then atomized into fine particles by compressed air and continuously sprayed. Oxide ceramics such as aluminum oxide, zirconium oxide, and chromium oxide can be sprayed. Since only fully melted materials are sprayed, the sprayed coating does not contain unmelted particles, resulting in a high bonding strength between particles, which leads to a relatively tough coating.

• Processing Contract

◆◇◆ What is Self-Fusing Alloy Thermal Spraying ◆◇◆ It is a method of forming a fused coating on the substrate surface by heating self-fusing alloy powder after thermal spraying to the melting point of the material (fusing). Self-fusing alloys are alloys of nickel-based, cobalt-based, or nickel-chromium-based alloys with the addition of boron and silicon.

• Processing Contract

◆◇◆ What is a Ceramic Anilox Roll ◆◇◆ After ceramic thermal spraying and grinding processing on the gravure roll, which is the heart of converting machines, laser engraving (to form fine indentations) is applied. Ceramic anilox rolls have several times the durability compared to traditional plated mesh rolls. Ceramic anilox rolls are utilized in flexographic printing - ceramic anilox rolls, gravure printing - solid plates, various laminations - ceramic gravure rolls, various coaters - ceramic gravure rolls, and high-precision rollers for processing LCD parts, among other applications.

◆◇◆ What is Grinding and Cutting Processing ◆◇◆ Since the introduction of the crank grinding machine in 1952, we have over 50 years of experience in grinding processing. We perform a wide range of processing, from standard metal grinding to high-hardness coatings such as ceramics and cermets. Additionally, we have various types of cutting machines installed.

• Processing Contract

◆◇◆ What is Vacuum Plasma Spraying ◆◇◆ Vacuum plasma spraying is a plasma spraying method conducted in a controlled inert gas atmosphere. As the substrate's residual heat temperature and the temperature during spraying increase, the flight speed of the particles also becomes very fast, resulting in higher coating density and stronger bonding. Due to the high temperatures of both the substrate and the spraying process, the melted particles do not solidify rapidly upon contact with the substrate in a vacuum. Compared to atmospheric spraying, the molten state of the particles lasts longer, allowing for seamless spraying on substrates with irregular shapes.

In welding, there are restrictions on the material properties. It is said that there is a dilution rate of about 30%, and to achieve the catalog hardness, it is necessary to apply three layers, which also leads to distortion of the material. Thermal spraying can keep the material temperature below 100°C, preventing distortion, allowing for processing of both new and repaired items without distortion. ●How does thermal spraying adhere? Basically, there are no issues in areas that rotate or slide, but in areas with impacts, it can cause peeling.

●What is the difference from plating? Plating originally leaves a hard layer on top through a thin plating buff finish, but for precision-required machine parts, thick plating and grinding finish are used, which removes the original hard layer, resulting in a lower hardness from the top layer down to the underlying material. Thermal spray coatings have a uniform structure and hardness throughout the cross-section of the coating. ●What is the thickness of thermal spray coatings? Standard thickness of ceramic and cermet thermal spray coatings: 100μm to 300μm Standard thickness of wire thermal spray coatings: 1mm to 10mm Standard thickness of self-fusing alloy thermal spray coatings: 0.5mm to 0.8mm ●How much does thermal spraying cost? The price varies depending on factors such as the area to be sprayed, the spraying equipment, the spraying materials, whether it is a continuous spray or if grinding finish follows the spraying, so estimates are often provided on a case-by-case basis. ●Is re-spraying possible? Even hard thermal spray coatings can wear down over many years of use. In such cases, it is possible to remove the thermal spray coating and then re-spray.

●What is the difference between thermal spraying with low-arc and plasma ceramic thermal spray coatings? Low-arc thermal spraying fundamentally uses high-pressure gas. In Japan, where the law requires lower pressure than overseas, can it exhibit its original performance? Additionally, the rod-shaped thermal spray materials are expensive, and the joints where multiple rods are extruded can become unstable. Moreover, there are only four types of materials available, while plasma spraying offers over 100 types of materials. ●Can you create materials from drawings? Basically, we often receive supplied items, but we can also create materials from drawings. ●What is the delivery time? Is it material supplied? Is it material created from drawings? What is the quantity? What is the spraying method? Is there grinding processing? ... There are various conditions, so the delivery time will vary each time. Generally, we prioritize the delivery time requested by the customer, but please understand that it may also vary depending on the volume of orders within the company. ●How does delivery and pickup work? Basically, for pickup and delivery, our sales team operates within a range accessible by car, but for remote areas, we use truck services, covering all of Japan.
