Cold spray solid additive manufacturing technology is an additive manufacturing technology with no size restrictions. It can be used for additive manufacturing of large components and splicing of dissimilar materials. Through independent research and development, our company has mastered the cold spray solid additive manufacturing process of various materials. The applicable range of materials covers pure metal materials such as copper, aluminum, silver, titanium, nickel, tantalum, zinc, tin, aluminum alloy, copper alloy, titanium alloy, stainless steel, high-temperature alloy and other alloy materials and customized composite materials.

Typical case:

■ Bimetallic composite material-copper-titanium composite pipe additive manufacturing
In response to the marine corrosion problem of a certain ship type, our company has developed a cold spray solid additive manufacturing bimetallic composite material, breaking through the difficulty of preparing large-size bimetallic composite materials that cannot be achieved by traditional processes. The material body increases the electrode galvanic corrosion rate, enhances the anti-corrosion performance of the seawater pipeline system, and at the same time slows down the marine corrosion problem, greatly improving the service life of the ship. This technology has been applied in batch engineering in the field of navigation, with significant economic and effects.

■ Target additive manufacturing
Our cold spray solid additive manufacturing technology can additively manufacture various metal and alloy targets such as Zn, Al, Cu, Ag, Ti, Nb, Ta, etc. The direct molding target has high production efficiency, good bonding with the backing, and finer grains than casting. Directly molded large metal sputtering targets have been used in the electronics and information industries, such as integrated circuits, information storage, liquid crystal displays, laser memory, electronic control devices, glass coating and other fields.

The main forms of damage to metal parts include wear, corrosion, and fatigue cracks. Metal spraying additive remanufacturing is a non-destructive additive remanufacturing method that can repair the size, performance, and even structure of metal parts, providing a novel and unique solution for the maintenance of metal parts with high added value and high performance requirements. Our company has mastered the complete additive remanufacturing technology of metal parts size restoration, corrosion repair, surface repair, and structural reinforcement.

Through metal spraying additive manufacturing, functional coatings of various properties can be prepared on the surface of metal, ceramics, and plastics. Through long-term intensive cultivation and continuous investment in the field of surface engineering, our company has developed a variety of functional coatings including thermal conductive coatings, conductive coatings, wear-resistant coatings, corrosion-resistant coatings, anti-friction coatings, sealing coatings, insulation coatings, thermal insulation coatings, etc., which are widely applicable.

Through years of maintenance experience in the aerospace field, our company has independently developed a mobile additive manufacturing platform, which has the characteristics of strong repair ability, good environmental compatibility and simple and convenient operation. It can perform on-site emergency repairs of conventional aircraft components such as aluminum alloy, titanium alloy and high-temperature alloy in multiple scenarios, ensuring the function, performance and flight safety of the aircraft, and providing a new solution for the field protection of the aircraft body structure. (Freak damage, cracks and corrosion are the main forms of damage to the aircraft body structure, especially in various aircraft under the four high environments, structural corrosion, damage, fatigue crack failures occur frequently.)

The company team has more than ten years of R&D experience and technical accumulation in the field of precision machining equipment, independently mastered the key technologies of mechanical, electrical, hydraulic and control systems, and continuously made breakthroughs in integrated design, component integrated development and component manufacturing process innovation, forming 13 core utility model patents, and the precision indicators of roller products such as roundness, straightness, surface finish, etc. can achieve the effect of presenting a bright belt after wiping. The core product technology breaks the international monopoly, and some products have successfully replaced similar products of well-known manufacturers in Germany, Japan and Italy, and achieved independent export and supporting export.

Relying on additive manufacturing technology, the company focuses on application services in the field of new energy vehicles. In the manufacturing of new energy vehicle parts, its products include ECar aluminum profile shells, all-aluminum bodies, aluminum upper covers, module side panels, water cooling plates, ebike aluminum profile shells, new energy battery tray profiles, etc. The company has the ability to provide everything from molds and process design to full-process production support according to customer ideas, focusing on the research and development and manufacturing services of aluminum alloy lightweight products, all-aluminum bodies and components.
