Plastic housing/bracket components for automotive electronic equipment

Plastic housings/brackets for automotive electronic equipment are indispensable protective and supporting carriers in automotive electronic systems. They are made of high-performance engineering plastics such as ABS, PC, PBT and PC/ABS alloys through precision injection molding. Its structural design combines functionality and adaptability. The housing is usually a closed or semi-closed cavity with a reasonable layout of buckles, slots, mounting columns and other structures inside to stably accommodate electronic components such as on-board sensors, controllers, and display screens; the brackets are mostly hollow and lightweight designs, and seamlessly connect with the car body and interior parts through precise positioning holes to achieve reliable installation of electronic equipment.
