Automotive Gear Shift Knob Boot Assembly

We provide detailed drawings, including 3D digital models, material specifications, and stitching color standards, to facilitate accurate manufacturing cost assessment for this gear shift mechanism assembly. As a critical component connecting the cockpit to the transmission linkage, its structure integrates an injection-molded base skeleton, a metal rod body, and a flexible dust boot, ensuring stable coordination of all parts during dynamic operation.

The manufacturing process covers injection molding, rubber/leather covering, and precision assembly. Key processing focuses include controlling the flatness of the bottom mounting seat and the tolerance of bearing hole positions to ensure smooth shifting with no play. Simultaneously, we strictly manage the vulcanization or stitching processes of the dust boot to prevent uneven wrinkles or seal failure, ensuring the boot possesses excellent wear resistance and anti-aging properties during long-term reciprocating motion.

Our factory holds IATF 16949 quality management system certification and is equipped with Haitian injection molding machines and rubber injection molding equipment. We also possess testing instruments such as electronic tensile testing machines and high/low-temperature test chambers, enabling independent full-process delivery from mold development to finished product assembly. We support sampling verification based on customer-provided samples or drawings, meeting the stringent acceptance standards of OEMs regarding interior appearance defects and functional durability.
