This computer mouse is designed with a clamshell structure, and its components, including the upper shell, scroll wheel, optical lens assembly, scroll wheel shaft, and lower shell, are all manufactured through injection molding. The lower shell features a complex design with multiple reinforcing ribs and pillar placements. GV Mold has carefully crafted the mold design, carried out precision mold machining, and strictly controlled the injection molding parameters throughout the production process. This diligent methodology has effectively prevented any potential defects such as flashing, incomplete filling, flow marks, air traps, warping, silver streaks, and cold slug formation in the mouse’s outer shell, thereby ensuring a flawless final plastic product.
