Guided by the philosophy that professionalism creates value, we focus on the specialized vehicle industry with a strong commitment to new energy research and manufacturing. We have established a year-round production program dedicated to new energy commercial vehicles, with a product lineup spanning more than 40 models. This includes sanitation trucks, concrete mixer trucks, urban logistics vehicles, and road maintenance vehicles.
Our specialized vehicles are designed to meet the needs of multiple application scenarios, ranging from urban street cleaning and waste transfer to cold chain logistics, concrete transport, and road maintenance. By aligning advanced production with rigorous quality control, we ensure that every vehicle delivers dependable performance across diverse professional environments.
Equipped with high-precision machining capabilities, we are able to achieve cutting accuracy of ±0.25 mm and surface roughness of 25μm–50μm, ensuring precise and consistent parts.
Advanced bending and forging equipment meets the sheet metal forming requirements of multiple vehicle types, enabling one-time forming with exact dimensions.
More than ten specialized welding procedures are in place to handle components of various sizes. Automated welding equipment further ensures strength, consistency, and durability.
Dedicated sandblasting, painting, and baking facilities provide vehicles with corrosion resistance and long-lasting finishes.
Professional tooling and fixtures are used to support the precise assembly of core components.
DESA has established a complete quality control system capable of conducting inspections and tests from individual components to the finished vehicle. A wide range of experiments and trials are carried out to verify durability, safety, and reliability under different conditions:
Mechanical performance testing
High and low temperature testing
Salt spray corrosion resistance testing
Metallographic analysis
Component rain simulation testing
Structural fatigue testing
Testing highlights
R&D capabilities
Collaboration & exchange
