This process is suitable for mass production, has significant cost advantages, is light in weight, meets the needs of lightweight vehicles, allows for the integration of functional structures, and is flexible in design.

[0003] Vehicle air shrouds produced by injection molding will also encounter common problems of injection molding, such as: shrinkage and deformation during the cooling process causing the air shroud to twist or warp, and mold wear, unstable temperature control, or changes in material fluidity may lead to inconsistent dimensions of continuously produced products. The vehicle air shroud needs to be inspected to ensure compliance with aerodynamic design, assembly clearance, and positioning accuracy of fixed points. The vehicle air shroud itself has a 3D streamlined structure and is relatively thin. A three-coordinate measuring machine is usually used to take points on the surface of the air shroud for inspection. This inspection method requires high skills from the inspectors, increases the difficulty of personnel training, and the more points are taken, the higher the accuracy, which affects the inspection efficiency.
