Gravity casting is typically used for heavy products and high-volume production runs.

High-Pressure Casting & Gravity CastingĪt The Federal Group, we also offer high-pressure casting and gravity casting based on the requirements of the project. Depending on your specific project, little to no machining is required. It remains one of the most efficient casting processes, especially for high-volume production runs. In the end, die casting is the preferred choice for a wide range of applications. It is also a more time-consuming process. While investment casting requires less tooling, the price per unit is often higher. This process allows for very intricate designs and greater precision compared to die casting parts. The wax is then melted, leaving an empty ceramic mold. The wax patterns are coated in a ceramic material that eventually hardens. With our investment casting services, we create wax patterns from a master die. Investment casting is another casting process offered at The Federal Group. However, this process typically involves fewer components and assembly operations along with a closer net shape. Stamping is preferred for simple parts and rapid production. Our stamping equipment allows us to work with steel and alloys that may not be suitable for the die casting process. Metal stamping is another service that we provide for the fabrication of quality parts. Our die casting services include fast turnaround for most projects. If you have a short timetable for your product development cycle, die casting is the preferred choice. However, sand casting is a more exhaustive process. Sand castings can be made from various ferrous metals and non-ferrous alloys. While we offer alloy die casting services, die castings do not work with all materials. Sand castings are also suitable for a wider range of materials. Our sand casting process produces high-quality parts with minimal porosity and defects compared to die casting.

When the metal cools, the sand is blasted away. The molten metal is poured into the mold to create the desired shape. The model part is placed in the mixture, creating a mold. The sand casting process includes a mixture of sand and clay pressed into boxes called flasks. While die casting relies on high pressure to force the liquid metal into the mold, sand casting involves pouring liquid metal into a mold. Hot chamber casting provides an efficient solution for tin, zinc, and alloys with lower melting points. Metals with a high melting point require the use of a separate furnace, which is not an option with hot chamber systems.Ĭold chamber casting is best suited for working with materials like brass, steel, copper, nickel, iron, and occasionally aluminum. The main advantage of cold chamber casting is the ability to work with a wider range of metals. The additional step of transferring the molten metal increases the production cycle. The cylinder extrudes the metal into the die using a piston. The molten metal is transferred to the machine using an injection cylinder. Instead of a built-in furnace, these machines require a separate furnace to melt the metal. The hydraulic-powered piston then forces the metal into the die at a fast pace with a typical cycle lasting just about 15 minutes.Ĭold chamber systems include an extra step in the process. The machine has a built-in furnace to heat the metal. Hot chamber systems rely on a piston to force the molten metal into the dies. Depending on the material and timeframe, we may use a hot chamber machine or a cold chamber machine. We employ two types of machines for die casting.
