Stainless steel casting door lock

Guangdong stainless steel casting hardware locks refer to equipment with a closed function. It includes locks, keys, and notes. It is usually expressed as "a sealing device that must be justified with a key". Nowadays, hardware locks can be opened with a key. Commands such as exhaust, electricity, magnetism, sound and fingerprint recognition are turned on. Hardware locks are not only protective equipment, but also have the functions of "management methods" and "decorative design". This kind of etiquette knowledge is also used in international communication, and the representative "key" is used as an expression of friendship.
There are two types of lock materials, one is wooden lock and the other is metal lock. The production and manufacture of wooden locks need to go through the production process of sawing and cutting materials, axe splitting and forming, gouging and drilling, and cutting and turning holes. Metal material locks require the smelter, gold, silver, copper and iron, billet casting, laser cutting and cutting, welding and riveting, drilling, drilling, filing, polishing and other hardware accessories production processes. From the raw materials to the production of a hardware lock, I don’t know how hard it takes the unlocking masters to work!
When everyone buys hardware locks, they are widely worried that the surface of the hardware locks will not be durable or will not be used for long. The surface will rust or oxidize. This problem is related to the application of raw materials and metal surface treatment problems.
From the perspective of durability, the best raw material for automatic coffee machine parts should be stainless steel plates, especially when used as surface materials, which become brighter and brighter. Its compressive strength is good, corrosion resistance is strong, and the color tone will not change. However, stainless steel plates are also diverse, and the key can be divided into metallographic structure and ferrite. Stainless steel round pipes are magnetic, aliased as stainless steel 201, for a long time, and the natural environment is not so good that they will rust. Only low-alloy steel is not easy to rust. The identification method is very simple, and you can identify it with a magnet.
Increasing the sleeve is one of the most commonly used hardware lock materials. It has good physical properties, excellent corrosion resistance and production and processing characteristics, and the color is bright. It is very copper forged door handle and its hardware lock ornaments. The surface layer is neat. Flat, good relative density, no vent holes and sand holes. It is strong and anti-rust treatment. It can be used for 24K gold plating or placer gold and other metal surface treatments. It looks graceful and elegant, adding many colors to everyone's home furniture.
Zinc alloy material has much worse compressive strength and anti-rust treatment ability, but its advantage is that it is easy to make parts with complicated patterns, which is very working pressure forging. The locks with more complicated patterns that are heard on the market will be made of zinc alloy materials. Customers should distinguish them carefully.
Intelligent robot stainless steel accessories have good compressive strength and low cost, but they are easy to rust. They are usually used as raw materials for the construction of hardware locks and are not suitable for external ornaments.
