The production process of bronze bushing includes casting, heat treatment, machining, polishing, quality inspection and other steps. Here is a guide to these steps:

Bronze bushing production process 1: Casting: In the casting stage, the tin bronze alloy material is first melted and then poured into the mold to form a casting. In this process, it is necessary to precisely control the melting temperature and pouring speed to ensure the quality and stability of the casting. After that, the casting is cooled and cleaned to remove surface impurities and extra parts to ensure the cleanliness and precise shape of the casting.

Bronze bushing production process 2: Heat treatment: Heat treatment is to change the organizational structure of the tin bronze bushing material by heating and cooling, so as to obtain the required mechanical and physical properties. During the heat treatment process, the heating temperature and holding time should be controlled to avoid deformation or cracking of the material.

Bronze bushing production process 3: Machining: Machining includes turning, milling, drilling and other operations, the purpose is to make the cast tin bronze bushing to achieve the exact size and shape. Machining to ensure machining accuracy and surface quality, choosing the right cutting tools and process parameters is the key.

Bronze bushing production process 4: Polishing: polishing operation is to improve the surface quality of tin bronze bushing, remove the surface roughness and scratches caused by mechanical processing. In the polishing process, the use of polishing agent and polishing time should be controlled to achieve the improvement of surface finish.

Bronze bushing production process 5: Quality testing: Quality testing is an important part of the production process, including size testing, hardness testing, non-destructive testing and so on. This process ensures that the product meets the requirements of the standard, including the appearance and internal quality. Choosing the right testing methods and tools is crucial to ensuring product quality.

In general, in the production process of bronze sets, from the selection of raw materials to the quality inspection of the final product, every link needs strict control and fine operation. With the development of manufacturing technology, new process methods such as precision casting and CNC machining are widely used in the production of bronze bushings, which further improves the quality and production efficiency of the products.
