Smart door lock back cover

🔥 Integrated die-casting for a dense and robust structure: Utilizing 300T to 1500T aluminum alloy die-casting machines, the main body of the back case is formed in a single process. The aluminum alloy material combines lightweight properties with high strength, perfectly withstanding the vibrations and impacts from modules like the lock motor and circuit board. Simultaneously, it leverages the metal's thermal conductivity to assist in heat dissipation for the mainboard, extending the lock's service life.

🛠 Precision machining chain, attending to every installation detail: Internal threaded holes are processed by automatic tapping machines, while CNC precision machining ensures the flatness of the battery compartment and the positional accuracy of various interfaces. Automated deburring and polishing make every edge smooth and safe, enhancing assembly efficiency and user experience.

🔬 Comprehensive dimensional inspection, endorsing outdoor durability: A Coordinate Measuring Machine (CMM) precisely verifies mating dimensions. A salt spray tester simulates coastal high-humidity environments, while a temperature & humidity chamber validates structural stability under extreme conditions ranging from -40℃ to 70℃. Every smart lock back case shipped has proven its ability to withstand the test of time.

Shiny Mold ensures that every smart lock has stable and reliable "rear" support.
