Tin bucket is also quite common in life. With the development of the times, more and more people will choose plastic bucket, but there are still a group of people who are still using iron oil bucket. It is understood that the manufacturing process of iron barrel is very messy. Do you know anything about it? Follow Jiangmen iron bucket manufacturers to understand it!

The tin barrel has good comprehensive properties, good strength, plasticity and welding properties, and is widely used. Before making tin barrel, a very important process is material selection. The quality of material selection directly affects the quality of the finished product. Therefore, this step is very important for the production. The tin barrel belongs to the sheet metal part, so it has a high requirement for the tensile property of the data. After selecting a good plate, the tin barrel enters the blanking stage.

Driven by the servo feeder, the information of the tin barrel is cut into the same shape sheet by the mold. Next, we need to punch into two halves of the same shape through punching. This step is completed. In the future, the tin barrel needs to enter the forming stage. The sheet metal of the tin barrel is placed under the mold, and the lubricating oil is applied on the surface of the data, which is conducive to the demoulding of the product. The press drives the mold to move back and forth, and the corresponding tin barrel is also in batch production, and the holes are drilled on the tin barrel. Of course, the welding of tin barrel is also very important. Welding is to weld two pieces of stamping tin barrel together. After welding, the welding scar needs to be polished. Then the coating of the tin barrel is carried out. Select suitable coatings, confirm good working environment conditions, carry out quality, process management, technical economy and other important links.

Through the above processes, the production of tin bucket is completed. Now, the production process is not simple, but there are still many people using it in modern life. Compared with plastic bucket, it also has certain advantages. The above is the content of Jiangmen tin bucket manufacturers, I hope to help you.
