Materials Used in Brass Investment Casting

The materials generally used for casting molds are resin, water glass, clay, raw sand, and various auxiliary materials. However, special investment casting involves ceramic mold casting and metal mold casting. Almost any metal that is castable can undergo investment cast. Usually, brass and copper are used for brass investment casting. The process of brass casting is done under extremely high temperatures.

Brass Investment Casting Process

The initial stage of brass investment casting is the creation of a master die from the wax. The wax pattern can be carved by a machine, by hand, or created by the process of injection molding. The die used is the same as the part to be made. The die is stuck on a rod of wax called a sprue. A number of the wax patterns can be attached to the same sprue. However, it can also be just a single wax pattern.

The master dies are then attached firmly to allow the assembly to be inverted and dipped into an investment. It may undergo dipping multiple times to achieve an even coating and the desired thickness. Another way of tackling this is by mounting the assembly in a flask and pouring it into the ceramic slurry. Afterward, the investment has to be left to dry.

molten metal being poured into ceramic shells

The drying process will require several hours; however, the process can be aided by a vacuum or a fan. When it has dried fully, the assembly is brought to an oven, where it is inverted and baked to vaporize or melt the wax.

The mold must be heated many times to ensure that there is no residual wax or moisture that would affect the liquid brass driven into the open space left by the wax. For the mold to be completely filled, the molten metal has to be drawn in through positive air pressure, a vacuum, or other centrifugal casting methods. Afterward, the brass is left to cool down and harden into a solid. The investment mold can then be removed for the brass casting inside to be released.

Applications of Brass Investment Casting

Brass castings are of great importance. They are used in many applications, such as for dental and medical tools, pipes, engines, propellers, fittings, nozzles, tees, radiator plugs, brass elbows, valves, and couplings. Their use is also employed in the chemical, aerospace, mining, military, electrical, food processing, sports, construction, telecommunication, and other industries.

investment casting applications

The use of metal parts can be witnessed every day domestically, industrially, and commercially. For centuries, the process of brass investment casting has been used for the production of jewelry.

Advantages of Brass Investment Casting

There are several advantages of brass investment casting over other manufacturing procedures, as stated below:

  • The process of investment casting creates parts that are lightweight and very precise.
  • The process can be done using a wide range of metals, including aluminum, steel, and gold.
  • Brass investment casting produces a detailed and smooth end product without any parting lines or flash.
  • The final product has smaller diameter holes than die casting, forging, or sand casting.
  • Brass investment casting is environmentally friendly and has great dimensional geometry on the final product.
  • There is no tooling cost required. The brass investment casting products are also in various grades and sizes.

However, a major drawback of investment casting is that it is very expensive compared to other manufacturing methods.
