Brass Casting

In the engineering of components for a new project, it's important to select the right metal alloy and casting method. Brass casting is a popular choice for a wide variety of applications due to the unique properties of brass and the brass casting process's cost-effective nature. At J. Walter Miller, we provide brass casting service in Pennsylvania. If you're looking for a foundry that can handle small and large orders quickly, we can meet your needs.

What Is Brass Casting?

Brass is a generic name that encompasses alloys made from copper and zinc. Brass casting involves using these metal alloys to form metal parts efficiently. Green sand casting is one of the most reliable methods for brass casting. This technique involves forming a single-use mold from a sand aggregate and pouring molten brass into that mold. The process works well thanks to sand's ability to withstand extremely high temperatures.

Brass Casting Applications

Brass castings find use in many industries, and brass components prove especially useful in household and construction applications due to the material's natural corrosion resistance. At J. Walter Miller, we create brass connectors, switch gears, pump parts, valves, sprinkler heads and more. Industries that rely on brass casting services include:

  • Fire protection
  • Flow Control
  • Construction
  • Plumbing
  • Electrical
  • Hardware
  • Pneumatics

Brass Casting Equipment

Brass casting foundries utilize specialized brass casting equipment to produce high-quality results. This equipment includes specialized melting furnaces to heat metal to the appropriate temperature and vibratory equipment to remove finished castings from their sand molds. We use automated equipment at every stage of the brass casting process to keep costs low and lead times as short as possible. Automation also allows us to produce consistent parts free of defects.

Our Brass Casting Process

Our brass casting process involves three primary steps:

  1. Mold-making: We start by making match plates for each component. The sand is then pressed around the match plate to create new halves of a mold. A pattern is a full-size prototype of the part being manufactured. For more detailed aspects of the component, patterns are used to create cavities inside the mold. Next, we fasten the mold together in preparation for pouring.
  2. Pouring: Once we've created an accurate sand mold, we heat brass to an ideal casting temperature inside a furnace. The molten brass then flows into the mold gradually. After the pouring process, we leave the filled molds to cool and solidify.
  3. Removal: Finally, we remove the finished, cooled castings by breaking open the molds. Depending on the type of component being made, we also smooth the surface of the piece and remove extra metal if necessary.

Brass Properties

Finished brass casting can provide benefits such as:

  • Resistance to corrosion and rust
  • Strength and wear-resistance
  • A hygienic surface
  • Good electrical conductivity

Our Brass Alloy Types

At J. Walter Miller, we work with several different alloys. Four common brass alloys that we work with are as follows — C84400 Leaded Semi-Red Brass, C83600 Leaded Red Brass and two types of non-leaded red brass. Each alloy works best in specific applications. To learn more about our custom brass casting services in Pennsylvania, reach out to us today.
