Fingerprint lock selection guide one see material

Fingerprint locks are mainly made of three kinds of materials, namely plastic, zinc alloy, stainless steel. Among them, the durability of plastics, fire, explosion-proof performance is the worst, followed by zinc alloys, stainless steel is the best. Due to the complicated domestic security environment, fingerprint locks in China generally use zinc alloys and a small amount of stainless steel fingerprint locks. In view of national conditions, domestic consumers are best to choose stainless steel fingerprint locks when choosing a fingerprint lock, and they need to remember that “a look at the second knock on three volumes” of the optional word.

Fingerprint lock optional word 诀: A look at the second knock three 掂 volume

1, look at the appearance

Fingerprint locks of three materials appear to be almost indistinguishable from the outside, thanks to modern superb electroplating technology, the appearance of the different materials is almost similar to metal. Fingerprint locks on plastic materials generally have smooth surfaces and bright colors, while zinc alloys are slightly rough and sub-colored, and stainless steel is the most rough and subcolor.

2, knock

If it is difficult to "see" the fingerprint lock material, we can use "knock" to judge. Gently tap the sides of the lock body with your fingers (because the touch screen and other components of different materials are difficult to judge). If the sound is cloudy or empty, it is generally a possibility that the plastic products will be knocked on by stainless steel fingerprints. The sound of the shots was sharp and concentrated, there was not much sense of diffusion, and the penetrating power was better, and the zinc alloy had no sharp stainless steel in view of the sound, but it was clearer and brighter than the plastic products.

3, volume

If you use “see” and “knock” to judge whether or not the fingerprint lock material is good or bad, you can use one of the simplest and most useful methods to measure it. That is “grooming”. Everyone knows these three types. The material is light and heavy, plastic locks have a certain difference even if the internal components are very large (general plastic locks or poor quality materials) and zinc alloy or stainless steel, there will be some differences.
