Brass Casting Manufacturers-brass investment casting foundry

The process of brass casting in a brass investment casting foundry involves melting brass and using it as the molten metal. Sand casting, investment casting both are suitable method used for brass casting. Brass casting is a process where a mold is created and pouring molten metal into it, followed by air-cooling. Once the metal solidifies, the mold is removed. Brass is an alloy of copper and zinc, so the molten metal used in brass casting mainly consists of these two elements.

What methods are commonly used for Brass casting in a brass casting foundry?

Brass is a commonly used alloy material composed of copper and zinc. It has good mechanical properties, conductivity, and corrosion resistance, so it has been widely used in industrial production and daily life. There are many casting methods for brass, and the following will provide a detailed introduction to several common brass casting methods.

1. Brass Sand mold casting

This method is the most commonly used brass casting method. Its process includes steps such as mold making, melting brass, casting, cooling, demolding, and finishing. Firstly, create a sand mold based on the shape and size of the product, then melt the brass into a liquid state and pour it into the sand mold for casting. After the brass cools down in the brass casting foundry, the finished product is demolded and finally sorted and processed.

3. Brass Die casting method
Die casting method is a casting method that uses pressure to inject molten brass into a mold to form a product. Its process includes steps such as mold making, melting brass, injection, cooling, mold opening, and sorting. Firstly, create a die-casting mold based on the shape and size of the product, then inject the melted brass into the mold, fill the entire mold cavity with pressure, wait for the brass to cool down, and then open the mold to obtain the finished product. Finally, organize and process it.

4. Brass Vacuum casting method
Vacuum casting method is a method of casting brass under vacuum conditions. Its process includes steps such as mold making, melting brass, vacuum pumping, casting, cooling, demolding, and sorting. Firstly, a mold is made based on the shape and size of the product. Then, the brass is melted and placed in a vacuum casting equipment. Through an air extraction operation, the brass is fully wetted on the surface of the mold. After the brass cools down, it is demolded to obtain the finished product. Finally, it is sorted and processed.

5. Brass Continuous casting method
Continuous casting method is a casting method that utilizes continuous casting equipment to continuously cast molten brass into shape. Its process includes steps such as melting brass, continuous casting, cooling, cutting, and finishing. Firstly, the brass is melted and injected into a continuous casting equipment. Through the continuous casting operation of the continuous casting equipment, the brass is formed. After the brass cools down, it is cut into finished products, and finally sorted and processed.

The above are several common brass casting methods used in a brass  casting foundry, each with its own characteristics and applicability. When choosing a casting method, it is necessary to comprehensively consider factors such as the shape, size, quality requirements, and production cost of the product. At the same time, for different casting methods, it is also necessary to pay attention to operational norms and process control to ensure that the quality and performance of the final product meet the requirements.

Brass Materials commonly used in casting

Here are some common Brass casting materials that are commonly used in casting:

Yellow Brass (C85800)

Yellow brass is a copper-zinc alloy that is commonly used for casting parts that require good strength and corrosion resistance.

Red Brass (C87500)

Red brass is a copper-zinc-tin alloy that is commonly used for casting parts that require good strength, wear resistance, and ductility.

Silicon Brass (C87600)

Silicon brass is a copper-zinc-silicon alloy that is commonly used for casting parts that require good strength, corrosion resistance, and thermal conductivity.

High-Leaded Brass (C93200)

High-leaded brass is a copper-tin-lead alloy that is commonly used for casting parts that require good wear resistance and low friction.

Manganese Brass (C86200)

Manganese brass is a copper-zinc-manganese alloy that is commonly used for casting parts that require good strength, corrosion resistance, and wear resistance.

Naval Brass (C46400)

Naval brass is a copper-zinc-tin alloy that is commonly used for casting parts that require good strength, corrosion resistance, and seawater resistance.

Overall, These are just a few of the common brass casting materials used in the industry, and the specific material used will depend on the application and desired properties of the finished product.

In the brass investment casting foundry, in order to control the element and impurity content of the brass casting alloy, in addition to selecting furnace materials reasonably and calculating the ingredients correctly, it is also necessary to comprehensively consider the alloy’s performance and processing ability, furnace material properties, oxidation and volatilization melting loss, feeding sequence, melting temperature and time, etc. to determine the calculated composition.

For the pollution situation of flux, furnace lining and operating tools, etc, An estimate should be made and a pre furnace analysis should be conducted in the later stage of brass smelting to determine whether to replenish and dilute the material.

Sometimes the composition and impurity content of the brass alloy are within the national standard range, but there are small amounts of needle like or coarse intermetallic compounds in the brass ingot, or defects such as cold and hot cracks and regional segregation are prone to occur. Therefore, it is necessary to use phase diagrams to understand the solubility changes of solute elements, the equilibrium distribution coefficient of solutes, and the possibility of forming multicomponent compounds or non-equilibrium eutectic.

As long as the internal causes of the above defects are identified, our brass investment casting foundry can adjust the content of certain elements within the national standard range, supplemented by certain process parameters, or add modifiers to refine the grains, Improve the morphology of compound inclusions and the distribution of low melting point phases to achieve the goal of eliminating defects. The purpose of adding errors and adjusting the iron silicon ratio of aluminum in B30 is for this consideration.

On the premise of not reducing usability and processing performance, attention should be paid to saving more expensive metals when determining the ingredient composition of brass. For example, when melting H62 brass, according to the lower limit of its standard content range of 60.5%~63.5% Cu, the 61% Cu ingredient can save about 20 tons of copper for every 1000 tons of H62 melted compared to using 63% Cu.

Minimizing or not using intermediate alloys as much as possible can save fuel and raw material consumption in brass investment casting foundry. For alloys with high impurity limits, add more recycled materials and low-grade new metals to reduce costs.
