Automotive Gear Shift Knob

As a high-frequency human-machine interface component within the cockpit, this gear shift knob features a black textured soft-touch material on the top, combined with high-gloss silver trim on the sides. The base integrates an injection-molded skeleton with a metal connecting rod. Its ergonomic design ensures comfortable handling and precise transmission of shift commands, suitable for both passenger and commercial vehicle transmission systems.

The manufacturing process involves multi-material composite techniques, including hard plastic skeleton injection molding, surface electroplating or PVD treatment, and overmolding with soft rubber or leather. The core of the processing lies in controlling the fit gap between the trim and the main body to ensure a visually seamless transition and aesthetic appeal. Simultaneously, strict dimensional tolerances and coaxality of the bottom mounting interface are maintained to ensure a secure connection with the transmission linkage, preventing loosening or play after long-term use.

The factory holds IATF 16949 quality management system certification and is equipped with Haitian precision injection molding machines and rubber injection molding equipment. We offer one-stop delivery capabilities ranging from mold development and injection molding to post-processing surface treatment and assembly. The production line is supported by electronic tensile testing machines and high/low-temperature test chambers to verify material mechanical properties, weather resistance, and bonding strength of the cladding layer. Buyers can provide 3D digital models and appearance limit samples to evaluate mold solutions and confirm mass production delivery plans.
