Door lock hardware casting
Guangdong Stainless Steel CastingA lock is a closed device, which includes a lock, a key and its accessories. It is generally interpreted as "a sealer that must be opened with a key". Now, in addition to using a key to open a lock, it can also be opened with light and electricity. , Magnetic, acoustic and fingerprint commands are turned on. Locks are not only protective equipment, but also have the functions of "management" and "decoration". There is also a kind of etiquette in international communication, using the gift of symbolic "keys" as a sign of friendship.
There are basically two types of lock materials, one is wooden lock and the other is metal lock. The production of wooden locks must go through technological processes such as sawing and cutting, axe splitting, gouging and drilling, and planing and drilling. Metal locks need to be smelted, gold, silver, copper and iron, billet casting, cutting and cutting, welding and riveting, drilling and drilling, filing and polishing. From the raw material to the production of a lock, I don’t know how much it takes locksmiths to work hard!
When people choose locks, they are generally worried that the locks are not durable or the surface will rust or oxidize soon after use. This problem is related to the materials used and surface treatment.
Coffee machine accessoriesFrom the standpoint of durability, the best material should be stainless steel, especially as a surface material, the more you use it, the brighter it will be. It has good strength, strong corrosion resistance and unchanged color. However, there are many types of stainless steel, mainly divided into ferrite and austenite. Ferritic stainless steel is magnetic, commonly known as stainless iron. It will rust for a long time and in a bad environment. Only austenitic stainless steel will not rust. The identification method is very simple. You can identify it with a magnet.
Copper is one of the most widely used lock materials. It has good mechanical properties, good corrosion resistance and processing properties, and has a bright color. Especially forged copper handles and other lock decoration parts, the surface is flat, good density, no air holes, Trachoma. It is strong and rust-proof, and can be used to plate 24K gold or placer gold and other surface treatments. It looks magnificent, noble and generous, and adds a lot of color to people's homes.
Zinc alloy materials are much worse in strength and anti-rust ability, but its advantage is that it is easy to make parts with complex patterns, especially pressure casting. The locks with more complicated patterns seen in the market are most likely to be made of zinc alloy, and consumers must carefully identify them.
Robot stainless steel accessories, Good strength, low cost, but easy to rust, generally used as the internal structural material of the lock, not suitable for external decoration.
Aluminum or aluminum alloy, ordinary aluminum alloy (except for aerospace use) is soft and light, and the material strength is lower, but it is easy to process and shape.
