2. Premium Material Selection & Precision Manufacturing Process
The 552000103AADYJ tail door is crafted from high-performance automotive-grade materials, selected to meet Chery’s strict OEM quality requirements for exterior body components—prioritizing structural strength, corrosion resistance, lightweight design, and aesthetic consistency. The material selection is optimized to balance durability and weight, ensuring the tail door can withstand daily use, environmental exposure, and potential impact while contributing to the vehicle’s overall fuel efficiency.
The main panel of the tail door is constructed from high-strength steel sheet (specifically cold-rolled carbon steel with a tensile strength of 400-600MPa), a premium material widely used in automotive body components for its exceptional structural rigidity and impact resistance. This steel sheet is thin yet robust, providing the necessary strength to support the tail door’s weight, resist deformation, and absorb impact forces during collisions. To enhance corrosion resistance—a critical requirement for exterior components exposed to rain, road salt, and humidity—the steel panel undergoes a comprehensive anti-corrosion treatment process, including galvanization and electrophoretic coating. The galvanization process creates a protective zinc layer on the steel surface, preventing rust and corrosion, while the electrophoretic coating (cataphoretic coating) forms a uniform, dense film that further isolates the steel from environmental contaminants.
In addition to the steel main panel, the 552000103AADYJ tail door incorporates high-quality plastic components for non-structural areas, such as the inner trim panel and decorative elements. These plastic components are made from automotive-grade ABS (Acrylonitrile Butadiene Styrene) plastic, chosen for its lightweight properties, impact resistance, and ease of molding into complex shapes. The ABS plastic trim panel not only reduces the overall weight of the tail door but also enhances interior trunk aesthetics and provides a smooth, scratch-resistant surface. For the weather sealing function, the tail door is equipped with a high-quality EPDM (Ethylene Propylene Diene Monomer) rubber seal, which offers excellent elasticity, weather resistance, and aging resistance, ensuring a tight, weathertight seal between the tail door and the vehicle body.
The manufacturing process of the 552000103AADYJ tail door follows a strict industrial-grade production workflow, combining precision stamping, welding, surface treatment, and assembly technologies. The production process begins with the stamping of high-strength steel sheets into the required tail door shape using precision stamping dies. This stamping process is carried out under controlled pressure and temperature conditions, ensuring uniform material thickness, precise contours, and a smooth surface free from dents, scratches, or defects. After stamping, the steel panels are welded together using robotic spot welding technology, which ensures strong, consistent welds and maintains the structural integrity of the tail door.
Following welding, the tail door undergoes a series of surface treatment steps to enhance corrosion resistance and prepare for painting. The panels are first subjected to phosphating treatment, which creates a rough, adhesive surface that improves the adhesion of the subsequent coating layers. Next, the tail door undergoes electrophoretic coating, followed by a primer coat and a topcoat (matching the Chery Tiggo 8 Pro’s original factory paint colors). The painting process is carried out in a dust-free environment using electrostatic spraying technology, ensuring a uniform, smooth, and glossy finish that matches the vehicle’s exterior. After painting, the tail door is assembled with the ABS trim panel, EPDM rubber seal, and other components (such as hinges, latches, and handle), completing the manufacturing process.
Before leaving the factory, every single 552000103AADYJ tail door undergoes rigorous quality inspections, including dimensional accuracy testing, structural strength testing, corrosion resistance testing, paint quality testing, and fitment testing. These tests ensure that each tail door meets Chery’s strict OEM standards, with no defects or deviations that could compromise performance. Additionally, the tail door comes with a 12-month quality guarantee, reflecting the manufacturer’s confidence in its durability and reliability. Only units that pass all inspections are packaged and delivered, guaranteeing reliable performance and long service life in the Chery Tiggo 8 Pro.
