Handheld Vacuum Cleaner Plastic Housing Assembly

The cylindrical dust cup and elongated handle feature an integrated, streamlined design with a high-gloss metallic finish. The handle side includes operational buttons and a branding area. This complex curved structure demands high mold cavity polish and precise injection molding venting to ensure a flawless surface free of flow marks, shrinkage, and weld lines.

The component utilizes multi-color or two-shot molding techniques, tightly integrating the pink main housing with the blue-green grip/base. Parting lines are smooth, and tight tolerances are strictly controlled to prevent excessive assembly gaps or looseness. Typically manufactured from thermoplastics like ABS or PC, these appliance housings balance strength and impact resistance while meeting adhesion standards for subsequent painting or plating.

Our Shenzhen factory offers mature capabilities in plastic injection molding and mold manufacturing, providing end-to-end services from mold flow analysis and T0 trial runs to mass production. For complex housings with curved surfaces and button features, we strictly control key mating dimensions and surface quality grades. We support mold evaluation and prototyping based on 3D drawings to ensure consistency in bulk deliveries.
