1. High complex precision machining parts.

The mechanical lock cylinder of Huarui intelligent lock adopts the imported evva lock cylinder. The processing accuracy is the guarantee of the anti-theft lock performance. No matter how good the structure is, there is no anti-theft. The processing and assembly process of all parts of evva lock cylinder is as precise as that of "Swiss watch". The unique structure of evva lock cylinder prevents opening, especially the highest level of anti-theft MCS lock cylinder. There are 8 high-strength magnetic wheels inside, which are arranged on both sides of the key, 4 on each side. When opening, it is realized by 8 rotors driven by magnetic force. Because of the non-contact nature of magnetic force, the evva lock cylinder is easy to be opened, Therefore, there is no need to touch the core part of the lock, and other keys or tools cannot be opened.

2. Anti violence materials.

All evva lock cylinders are embedded with cemented carbide on the main body to prevent violent damage. The key is made of high-quality nickel white copper material, which ensures the highest wear resistance and will not rust.

3. Key protection.

Most people don't care if they lose the key, but they don't know that there is a big potential safety hazard. Because of the simple structure of the lock cylinder of evva, it can be matched with an ordinary gear cutter. Every lock cylinder and key of evva will have its unique code, which corresponds to its unique ID card. It also means that its key is also the only one that can be matched. It is protected by international patents, and other people can't copy it at will, The electronic license certificate is required when the key is copied, and the professional optical driven laser induced automatic keying machine is required.

4. Fire test.

The domestic lock cylinder does not have the function of fire prevention. In case of fire, the lock cylinder can not withstand high temperature and melt down. At that time, the door can not be opened even if you want to open it, which directly threatens your life. It is impossible for high-rise buildings to jump out of the window. If you can have a high-temperature lock cylinder, it is more important than how much money. At present, evva lock cylinder has not been opened by technology in China, and it has passed the 90 minute fire test in Europe, High temperature resistance and durability are guaranteed.
