Lost wax investment casting of brass special-shaped bracket

In the field of modern industry, brass rod, as an important metal material widely used in the manufacture of various mechanical parts and tools, plays an indispensable role. Understanding and mastering the manufacturing process of brass bars is of positive significance for optimizing the production process, improving product quality and promoting industrial development. The production and manufacture of brass special-shaped castings need to go through many technological processes, which we will introduce in detail one by one below.

First, mold manufacturing

Make aluminum mold or steel abrasive tool according to customer's drawings, and press wax mold.

Second, pressing the wax mold

The wax model of the product is produced by using the manufactured abrasive tool.

Three, shell molding and dewaxing treatment are carried out according to wax patterns.

Four, the smelting stage

First of all, the manufacture of brass shell mold needs to put raw materials such as copper and zinc into a melting furnace and melt them at high temperature. In this process, the impurities in the furnace will be separated to form the raw materials of brass special-shaped parts. Melting stage is the basis of brass special-shaped parts production, which has an important influence on the quality of subsequent products.

Five, Impurity removal stage

In the process of smelting, impurities such as iron and phosphorus in raw materials will form slag floating on the liquid surface. In order to obtain high quality brass rods, the slag must be removed to avoid its influence on the product performance. Impurity removal is generally achieved by adding appropriate flux, and vacuum impurity removal, filtration and other methods can also be used.

Six, the modeling stage

After impurity removal, brass liquid needs to be poured into the mold to form a brass rod with the required shape. During the molding process, the parameters such as temperature and pouring speed should be controlled to ensure that the size and performance of the product meet the requirements. At the same time, in order to reduce waste and improve production efficiency, suitable gate and runner design should be selected.

Seven, grinding stage

After the brass special-shaped parts are formed, the surface should be polished to remove the surface defects and improve the surface quality of the products. Appropriate abrasives and process parameters should be used in the grinding process to ensure that the surface roughness meets the requirements and avoid material loss caused by excessive grinding.

Eight, quality inspection and packaging

After grinding, strict quality inspection should be carried out, including size, shape and surface quality. Only brass special-shaped parts that meet the quality requirements can enter the packaging process. In the process of packaging, appropriate protective measures should be taken to avoid damage to the products during transportation and storage.

The manufacturing process of brass special-shaped parts includes die, waxing, shell molding, melting, impurity removal, modeling and polishing. Each link has an important influence on the final product quality. Therefore, the process parameters should be strictly controlled in the production process to ensure the stability of product quality. At the same time, strengthen research and innovation, constantly improve production efficiency and product quality, and provide better quality brass special-shaped products for modern industrial development.

In addition, for industrial applications, it is also very important to select brass bars with specific performance indicators according to actual needs. For example, in applications that require corrosion resistance and high strength, special brass special-shaped parts with appropriate elements such as nickel and tin can be selected. For high-temperature working environment, brass special-shaped parts with good high-temperature strength and fatigue resistance should be selected. Therefore, it is helpful to optimize material selection and product performance design to deeply understand the manufacturing process and its influencing factors of brass special-shaped parts.
