PRODUCT CENTER

Company Technology

HCMT Cold Welding Technology

Our company's HCMT Cold Welding Technology is an anti-corrosion technology and process developed through independent R&D and process design, based on the introduced international welding system platform in the welding field. It targets high chlor-alkali corrosion in garbage incinerators, biomass boilers, and other equipment.

Laser Cladding

Laser cladding technology is a new type of hard-facing technique introduced and developed by our company. This process uses a coaxial cladding nozzle that delivers cladding material onto the workpiece surface via a coaxial powder feed, while simultaneously directing a laser beam onto the substrate to create a molten pool. As both the cladding material and the base material melt, they rapidly solidify, forming a surface cladding layer with extremely low dilution and achieving metallurgical bonding with the substrate. This innovative method significantly enhances the wear resistance, corrosion resistance, heat resistance, oxidation resistance, and electrical properties of the base material's surface, enabling precise surface modification or repair. It not only meets the specific performance requirements for material surfaces but also helps conserve substantial amounts of valuable raw materials.

Fully Automatic Alloy Cold Arc Welding Deposition Technology

Our company has independently developed and designed a new automated alloy cold-arc welding deposition technology. This innovative process utilizes fully automated alloy cold-arc welding, combined with the company’s proprietary nano-amorphous alloy materials, to provide advanced wear-resistant protection for the severely eroded water-cooled walls in CFB boilers. As a result, it effectively extends the service life of boiler water-wall tubes, ensuring stable, safe, and reliable operation of the boiler system.

HVOF Supersonic Flame Spraying

HVOF supersonic flame spraying technology utilizes high-pressure oxygen combined with fuel (either gaseous fuel or aviation kerosene) to create a high-temperature, high-pressure, and high-speed gas flow through a specialized spray gun. This process propels powder particles delivered by the feeding system into the gun at supersonic speeds, where they are sprayed onto the workpiece surface. The result is a dense, uniform coating with low oxide content—perfect for functional applications in environments requiring exceptional wear and corrosion resistance. Since our company introduced HVOF technology in 2006, we have spent years thoroughly integrating and refining the process, while also developing innovative improvements of our own. As a result, we’ve not only preserved all the outstanding performance characteristics of the original foreign HVOF technology but have also achieved significant advancements, such as miniaturizing the equipment and enabling remote, real-time control. This has made it possible to carry out on-site construction directly inside furnaces, expanding its versatility across a wide range of demanding applications—including wear and corrosion-resistant environments found in waste-to-energy plants, biomass power plants, and other thermal power facilities.

Automated spraying

By employing supersonic arc spraying and high-velocity oxygen-fuel (HVOF) spraying technologies, on-site operations can effectively address wear and corrosion challenges. To fully leverage the unique advantages of these two spraying techniques, adopting automated processes is undoubtedly the key—this approach also aligns with the evolving trend in thermal spray construction methods at job sites.

Hengda High-Tech's headquarters rooftop distributed photovoltaic project successfully connected to the grid! Green energy powers a brighter future for the company.

On April 28, 2025, the rooftop distributed photovoltaic project at the Hengda High-Tech Headquarters Building—invested and constructed by Jiangxi Hengda New Energy Technology Co., Ltd. (a wholly-owned subsidiary of Hengda High-Tech, hereinafter referred to as Hengda New Energy)—officially connected to the grid and began generating electricity. The project makes full use of the rooftop and facade space of the headquarters building, operating under a self-generation-for-self-use model with surplus power fed into the grid. With a total installed capacity of 76.26 kilowatts, the system leverages high-efficiency monocrystalline silicon PV modules and an intelligent energy management system. It is expected to generate over 66,000 kilowatt-hours of electricity annually, equivalent to reducing standard coal consumption by approximately 22.3 tons per year and cutting carbon dioxide emissions by about 58.3 tons. This initiative not only injects clean energy into the company but also contributes significantly to optimizing the regional energy landscape.
