Split Zinc Alloy Door Lock Panel

The rose gold finished door handle assembly features a split-panel design with an ergonomic lever and integrated lock cylinder cutouts. This configuration is typical for high-end residential or commercial entryways, providing both aesthetic appeal and mechanical security through a robust backplate structure.

Manufacturing relies on high-pressure zinc alloy die casting to achieve the complex curvature of the lever root and the precise geometry of the mounting panel. Critical quality controls focus on the coaxiality of the square spindle hole and the flatness of the backplate surface to ensure smooth operation and prevent binding during installation. The finish requires meticulous polishing prior to PVD coating to maintain a uniform, scratch-resistant metallic luster.

Supported by IATF16949 and ISO 9001 certified processes, production utilizes 88T to 420T die-casting machines for consistent dimensional stability across batches. In-house capabilities include robotic polishing and rigorous validation via salt spray testing and mechanical fatigue cycles to verify durability in humid environments. Detailed 3D drawings are required to optimize gating systems and confirm tolerance specifications for custom orders.
