Container House Processing Technology
The processing technology of container houses mainly includes core processes such as steel pre-treatment, component welding and assembly, final assembly, final welding, and painting and beautification.
Steel pre-treatment is the foundation of container house manufacturing, involving the processing of steel plates and profiles. Steel plates need to go through steps such as uncoiling, flattening, sandblasting, and zinc powder application, followed by cutting, roll forming, trimming, and punching to achieve the desired shapes and dimensions. Profiles are sawed, sandblasted, treated with zinc powder, and then stamped to produce all components before being sent to the welding workshop.
In the component welding and assembly stage, components such as the base frame, front end, door end, and side walls are assembled and welded separately. Base frame welding includes the assembly and welding of components like fork pockets, bottom cross members, and bottom side rails to ensure structural stability. The front and door ends are welded into frames and equipped with door hinges, lock seats, and other components. Side wall welding involves processes such as corrugated welding and intermittent welding to ensure the strength and tightness of the welds.
During the final assembly phase, components such as the base frame, door end, front end, and side walls are hoisted onto the final assembly platform for positioning spot welding and fixation. Subsequently, the front and rear top corner reinforcement plates are welded, the top plate is installed, and spot welding is performed to position the top plate with the top side rails, forming a complete container house frame.
The final welding process involves reinforcing the overall structure through welding to ensure that the connections between components are firm and reliable. Painting and beautification is the final step, including secondary sandblasting, paint spraying, and topcoat treatment to make the container house aesthetically pleasing and corrosion-resistant.
In addition, container house manufacturing requires attention to the control of welding process parameters, such as weld penetration, leg height, and diagonal errors of the container body, to ensure structural accuracy and stability. At the same time, adaptive combination designs of container bodies are carried out according to actual needs, creating a wider variety of buildings through the assembly of container bodies to meet different usage scenarios and functional requirements.
