The surface of the B511F271301-0400 Bumper Grille is treated with a high-quality electrostatic spraying coating, available in a matte black or gloss black finish (depending on the Changan B511’s trim level), which not only enhances the vehicle’s aesthetic appeal but also provides superior corrosion resistance and UV protection. The electrostatic spraying process ensures uniform coating coverage, with a smooth, even surface that resists scratches, fading, and peeling caused by UV radiation, road salt, and environmental pollutants. This coating also protects the underlying ABS plastic from moisture and oxidation, preventing rust and degradation—particularly important for vehicles driven in coastal areas or regions with harsh winters, where road salt and moisture can accelerate component damage.
The manufacturing process of the B511F271301-0400 Bumper Grille follows a strict, ISO 9001 and IATF 16949 certified production workflow, consistent with Changan’s global quality standards and modern automotive component manufacturing practices. The production process begins with the injection molding of the ABS main frame and grid bars, which is done using high-precision injection molding machines to ensure dimensional accuracy (tolerance of ±0.03 mm) and structural integrity. The injection molding process is carefully controlled to avoid defects such as bubbles, cracks, or uneven surfaces, ensuring each component meets Changan’s strict quality standards.
After injection molding, the components undergo a series of post-processing steps, including deburring, sanding, and cleaning, to remove any imperfections and ensure a smooth surface. The electrostatic spraying coating is then applied, with the color carefully matched to the Changan B511’s original factory specifications to ensure a seamless aesthetic integration. The coated components are cured at a high temperature (110–120°C) to ensure the coating adheres firmly and provides long-lasting protection. The integrated mounting clips, made of high-quality elastic plastic, are then attached to the main frame using high-strength adhesive and mechanical fasteners, ensuring a secure and stable connection.
The entire assembly undergoes rigorous quality control testing to ensure it meets Changan’s strict performance and safety standards. These tests include impact resistance testing, temperature resistance testing, corrosion resistance testing, dimensional accuracy testing, and coating adhesion testing. Impact resistance testing verifies that the grill can withstand impacts from small gravel and minor collisions without cracking or deformation.
