Plastic injection-molded housings for household sweeping robots typically utilize materials such as PC/ABS alloys or antistatic ABS, offering a combination of high strength, impact resistance, scratch resistance, and dimensional stability. Precision injection molding enables the integrated formation of complex features, such as snap-fits and sensor mounts. Key advantages include V0-rated flame retardancy for operational safety and the ability to mold high-gloss, matte, or skin-like surface finishes directly, thereby reducing the need for secondary painting. Additionally, materials can be customized with antistatic or infrared-transmissive properties to meet the specific requirements of sensor windows. These materials are widely used for components such as the main body housing, dust bin, LiDAR protective cover, and control panels.
