The quality of the lock cylinder is closely related to the quality of the material.

The material of the lock nail is very important, it needs to have a certain degree of hardness and toughness, and it must also be resistant to wear and bending. The lock nail is preferably made of stainless steel or nickel alloy, such as copper wire, iron wire, aluminum, plastic, etc., which has poor anti-theft performance. The anti-drilling bolts and anti-drilling parts have high hardness, and the material of the key is also more particular, at least wear-resistant. In addition, high-level lock manufacturing ( https://www.yoursafetylock.com/ ) is made of nickel (16%) and manganese (2%) alloys. The accuracy of lock cores made of copper, iron, and aluminum alloys has the problem of insufficient accuracy.

In fact, the quality of this lock cylinder can be seen from the key. The more precise the key, the clearer and smoother the holes and slots, the more obvious the depth, the more obvious the unevenness of the lock cylinder, and the better the quality. Conversely, if the key is rough, the notch is not clear, the depth of the hole is not obvious, and the original color of the hole is different from the color of the key on the surface of the key, the quality must be poor. Simply put, a good lock cylinder is more eye-catching and more beautiful than a poor quality lock cylinder even from the outside.

2. Mixed structure based on rationality

The rationality of the lock core structure of combination lock manufacturers( https://www.yoursafetylock.com/product/combination-lock/ ) is very important to the quality of anti-theft. The industry generally believes that a single structure is worse than a mixed structure. This is because each structure has its advantages and disadvantages: pin locks have better torsion resistance, but poor resistance to shifting; blade locks have higher resistance to shifting and poor torsional and vibration resistance. . A single structure is prone to large-scale structural safety issues. After a certain secret has not been cracked, major security problems are prone to appear. We often encounter how many doors in a certain place are opened collectively, usually single-structure anti-theft locks. Locks with two or three mixed structures have higher anti-theft capabilities.
