Precision parts processing business is more in our Guangdong area, and electronic hardware factories are also one of the businesses that are commonly undertaken. Each company has its own set of guidelines for the quality of finished products. The finished products of standard precision parts are generally at a higher level. The processing of non-standard precision aluminum parts varies from factory to factory. The quality also changes with the needs of customers. There is no clear established standard. Therefore, what we are going to discuss here is how to distinguish the quality of finished precision parts?
If the precision parts of the door lock are processed as a case, first explain according to the material. The hardness and rust resistance of zinc alloy materials are very poor. Even thick electroplating is easy to fade, black, rot and blisters, but its advantage is that it is easy to make complex patterns. Precision parts, 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. Steel has good strength and low cost, but it is easy to rust. It is generally used as a material for the internal structure of locks and is not suitable for external decoration.

Aluminum or aluminum alloy, ordinary aluminum alloy (except for aerospace use) is soft and light, the material strength is low, but it is easy to process and shape. Copper is one of the widely used lock materials. It has good mechanical properties, good corrosion resistance and processing performance, and has a bright color. Especially for copper forged handles and other locks precision parts processing decorative parts, the surface is flat, good density, and no Stoma and trachoma. It is strong and rust-proof, and can be used for various surface treatments such as real gold plating or placer gold. It looks magnificent, noble and generous, and adds a lot of color to people’s homes.
From the standpoint of durability, the best material for precision parts cnc milling china 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 bad environment. At present, 304 stainless steel is accepted by most people.
