Wholesale Car Roof Box
Busman car roof boxes are a core product in outdoor travel storage solutions, designed specifically for global automotive aftermarket buyers. Leveraging high-quality PC/ABS, PC/ASA, and ASA/ABS composite materials and advanced vacuum forming technology, the products boast core advantages such as durability, lightweight design, and resistance to extreme environments. They have obtained multiple international certifications including CE, TUV, and ISO9001, are compatible with mainstream car models worldwide, and are the preferred partner for cross-border trade, OEM/ODM, and bulk purchasing.
Product Features
Busman roof boxes utilize industry-leading vacuum forming technology, achieving high-precision molding through four core steps: sheet preheating, vacuum adsorption, mold shaping, and cooling/setting.
Sheet material is heated to a constant temperature until softened, ensuring uniform material ductility.
Vacuum negative pressure tightly adheres the softened sheet material to the surface of a custom mold, precisely replicating the mold's contours.
Rapid cooling and setting prevents shrinkage and deformation, ensuring dimensional accuracy (error ≤ ±2mm).
Seamless design after molding enhances both the overall appearance and structural stability and sealing.
Compared to traditional injection molding, vacuum forming technology reduces raw material waste (utilization rate over 95%), increases production efficiency, and enables the manufacturing of larger sizes and more complex curved surfaces. This allows roof boxes to meet aerodynamic design requirements (streamlined appearance reduces wind resistance, increasing fuel consumption at high speeds by ≤5%) while maximizing storage space (volume up to 300-500L).
