Introducing the thermal spraying process "High Velocity Oxygen Fuel (HVOF)." Compared to conventional plasma spraying, it can form coatings with higher hardness and excellent wear resistance. The accelerated spray material undergoes minimal oxidation or compositional changes, resulting in a dense, high-quality coating with a low porosity rate (below 0.5%). 【Features】 ■ High hardness ■ Coatings with high adhesion strength can be obtained ■ Easier to achieve ultra-mirror finishes ■ Low porosity coatings are formed *For more details, please refer to the PDF document or feel free to contact us.

Introducing the thermal spraying process "Plasma Spray." All materials, including high melting point tungsten carbide ceramics, can be thermally sprayed. Since the plasma flame itself is inert, even low melting point metals like aluminum and copper can achieve pure and low-oxidation coatings. Similar to metallizing, it is possible to perform build-up thermal spraying at low temperatures around 100°C, preventing thermal effects and distortion on the base material. 【Features】 ■ Capable of thermal spraying high melting point materials ■ The thermal spray coating is extremely dense ■ A hard and dense coating equivalent to or exceeding that of hard plating can be obtained ■ Almost no thermal impact on the base material *For more details, please refer to the PDF document or feel free to contact us.

• Parts and Materials

Introducing the thermal spray process "Thermo Spray." It enables thermal spraying of materials that cannot be wire-formed, such as ceramic and tungsten carbide-based cermets. By re-melting the sprayed coating with an oxygen-acetylene (or propane) flame, an alloy layer is formed at the interface between the base metal and the sprayed coating, eliminating pores between the sprayed particles. 【Features】 ■ Enables thermal spraying of materials that cannot be wire-formed ■ Thermal spraying of self-fusing alloys ■ Prevents oxidation of Ni-Cr alloys ■ Lowers the melting point of Ni-Cr alloys, melting them at approximately 1000°C to 1100°C *For more details, please refer to the PDF document or feel free to contact us.

Introducing the thermal spraying process "Metallizing Arc." The wire-like materials used for thermal spraying are formulated from metals and alloys specifically for this purpose, allowing for spraying on any metal regardless of the base material. Since thermal spraying is typically conducted at low temperatures around 100°C, it does not affect the heat of the base material, preventing distortion or degradation. [Features] ■ Can be sprayed on any metal ■ Can be sprayed on any base material ■ Does not cause thermal effects or distortion to the base material ■ The sprayed coating is resistant to wear *For more details, please refer to the PDF document or feel free to contact us.

Our company offers a "husk carbonization furnace" that can process a large amount of lightweight raw materials. It can safely treat rice husks, and by partially combusting the husks to completely burn the pyrolysis gas, the running costs can be managed with just electricity expenses. Additionally, it only requires adjustments to the raw material supply and air volume, making it easy to operate. 【Features】 ■ Low cost and high quality ■ Simple and inexpensive ■ Capable of large-scale processing ■ Safe treatment of rice husks ■ Reduction of running costs ■ Easy operation *For more details, please refer to the PDF document or feel free to contact us.

• Incinerators and chimneys

The generation of sludge in Japan is said to amount to 75 million tons of organic sludge annually, and the main methods of sludge treatment are effective utilization and volume reduction. In either case, it is necessary to remove the moisture from the sludge. The methods for moisture removal include dewatering and evaporation, but evaporation incurs energy costs. As a new technology, we are advancing research and development on a method to remove moisture without incurring energy costs, known as "secondary dewatering." 【Main Methods of Sludge Treatment】 ■ Effective Utilization - Utilization as fertilizers, fuels, reducing agents, deodorants, etc. - Drying and carbonization are effective means for continuous large-scale processing. ■ Volume Reduction - After moisture removal, organic matter is reduced in volume through carbonization. *For more details, please refer to the related links or feel free to contact us.
