Manufactured using high-grade Zamak alloys and finished with a superior chrome plating process, this component is engineered to be the reliable core of high-quality locking mechanisms.
Ideal for padlocks, cabinet locks, toolbox locks, and various industrial security applications, our lock cases are produced with meticulous attention to dimensional accuracy and surface quality, ensuring seamless assembly and long-term performance.
Key Features & Benefits
-
Superior Material: Made from high-quality Zamak (Zinc-Aluminum) alloys (ZA-8, ZA-12, ZA-27) for excellent fluidity, allowing complex, thin-walled geometries with high strength and good stability.
-
Enhanced Chrome Plating: Electroplated with a bright, decorative chrome layer that provides exceptional corrosion resistance, high hardness for scratch resistance, and a visually appealing, easy-to-clean finish.
-
High Precision Die Casting: Utilizes advanced precision die casting technology to achieve tight tolerances, intricate details (like logos or part numbers), and consistent quality across high-volume production runs.
-
Excellent Durability: The combination of zinc alloy's structural integrity and chrome's protective coating ensures the housing withstands daily use, environmental exposure, and mechanical stress.
-
Design Flexibility: Capable of producing a wide range of shapes, sizes, and internal structures to meet specific lock mechanism requirements and brand identity (e.g., embossed letters like 'J', 'T').
-
Full-Service Support: From design consultation and mold making to precision casting, finishing, and quality inspection, we offer a complete one-stop manufacturing solution.
