The quality of the semi-trailer can be reflected in the details, and Fudeng semi-trailer has strict quality control whether it is the selection of materials or the manufacturing of parts.
Raw Material Procurement and Inspection
- Procurement Plan Formulation: According to the design scheme and production plan, formulate a raw material procurement plan, clearly define the specifications, models, quantities, and quality requirements of various raw materials such as steel, aluminum alloy, rubber, and plastic, and select appropriate suppliers for procurement.
- Raw Material Inspection: After the arrival of raw materials, the quality inspection department conducts strict inspections on them in accordance with relevant standards and acceptance specifications, including appearance inspection, dimension measurement, chemical composition analysis, and mechanical property testing, to ensure that the quality of the raw materials meets the design requirements and prevent unqualified raw materials from entering the production process.
Component Manufacturing and Processing
- Frame Manufacturing:The frame is the core component of the semi-trailer and is generally fabricated from high-strength steel through cutting, stamping, and welding processes. First, the steel is cut into the required shapes and sizes, then formed by punching, bending, etc. on a stamping machine, and finally, the individual components are assembled into a complete frame through welding. The welds are then subjected to non-destructive testing to ensure the welding quality and overall strength of the frame.
- Carriage Manufacturing:Depending on the different uses and design requirements, the carriage can be fabricated using different materials and manufacturing processes. For example, a common flatbed carriage is generally welded from steel plates, while a box-type carriage also requires interior installation and sealing treatment. During the carriage manufacturing process, attention should also be paid to dimension accuracy and welding quality to ensure the sealing, flatness, and overall strength of the carriage.
- Axle and Suspension System Manufacturing:The components of the axle and suspension system are usually provided by professional suppliers. The semi-trailer manufacturer needs to conduct quality inspections and assembly debugging on the purchased components. The machining accuracy of the axle directly affects the driving performance of the vehicle and the service life of the tires, and the suspension system needs to ensure that its shock absorption effect and load-bearing capacity meet the design requirements.
- Braking System and Electrical System Installation: The components of the braking system and electrical system are also mostly purchased parts. During the production process, they need to be installed and wired correctly according to the design requirements, and the systems need to be debugged and detected to ensure the reliability of the braking system and the normal operation of the electrical system.
