How to judge the quality of the lock body?

Lock body material

High quality material selection is the guarantee of lock body quality.At present, stainless steel is a common forging material in the industry, because steel has good corrosion resistance and oxidation resistance, making it very suitable for durable products such as locks.

Based on the proportion of lock body steel, the lock body can be divided into full steel and half steel. All steel is made of stainless steel for the outer shell, locking tongue, and internal mechanical structure of the lock body; The semi steel lock body mainly refers to parts such as the main lock tongue and reverse lock tongue made of stainless steel, while other parts such as the outer shell and diagonal tongue are made of iron and copper.

So, to judge the quality of the lock body from the perspective of material, it is necessary to distinguish between all steel and semi steel lock bodies. These two types of lock bodies have the following obvious differences: the full steel lock body shell is relatively smooth and bright, while the half steel lock body shell is dull and dull.

Lock body production forging process

In addition to the most important material, the internal structure of the lock body is also an important factor affecting quality.A good lock body has a very high mold accuracy, and the combination of internal components is very high. In terms of forging methods, good lock bodies are often forged using precision casting, so the internal components look very fine. The next best one is forged using die casting, which is not as precise as precision casting.

Lock body user experience

In addition to materials and craftsmanship, many dealers and installers with years of industry experience can judge from the subtle hand feel of the lock body during operation. Generally speaking, a good lock body runs very smoothly without any obstruction. For electronic locks, the sound and state during operation are also reference standards.
