Brass Investment Casting

Making a master die out of wax is the first step in the investment casting process for brass. Wax patterns can be hand-carved, machine-carved, or produced through the injection molding process. The part is manufactured and the die being utilized is identical. The die is fastened to a wax rod known as a sprue. The single sprue can hold a number of wax patterns. But it can also be a single wax pattern.

Brass investment casting produces lightweight, precise, detailed, and smooth-end products. In comparison to forging, sand casting, and die casting, this results in smaller diameter holes. All brass parts have great dimensional geometry. It is an environmentally friendly process.

Brass for Investment Casting

Ordinary brass materials are primarily composed of two main elements including zinc and copper. There are different types of brass based on its composition. However, special brass materials are produced using two or more elements other than zinc and copper.

The more zinc in the brass composition, the more strength and plasticity of the brass is. But when its mechanical properties exceed 47%, the mechanical properties of the brass will be reduced.

Aside from zinc, the brass casting also contains different types of alloys such as lead, aluminum, silicon, etc.

Why Brass is a Good Material for Investment Casting

Brass is widely used for investment casting process because of its different properties including:

  • Compared to copper, brass is more stress-cracking susceptible because of its stiffer and stronger properties
  • Excellent formability
  • Superior malleability, therefore, it is easy to work with
  • The melting point of the brass material is up to 900⁰C
  • Brass is non-ferromagnetic which makes it easy to recycle

Different Brass Forms

  • Bars
  • Tubes
  • Sheets
  • Pipes
  • Rods
  • Plates

Advantages of Using Brass for Investment Casting

  • Can be used for producing parts with complex and intricate features
  • Excellent dimensional accuracy
  • Can be integrated with superior surface finish
  • Small diameter holes
  • Does require any tooling
  • Environmentally-friendly
  • Tight tolerance up to +/-0.005
