Our Lost-Foam Casting Process
Using expanded polystyrene foam, a foam pattern of the desired part is produced. The pattern is shaped precisely to match the final design.
The foam pattern is coated with a ceramic slurry to create a mold shell. This layer provides the necessary strength for casting.
The coated foam pattern is allowed to dry, hardening the ceramic shell. This step ensures the mold is sturdy enough to handle the molten metal.
Multiple foam patterns are arranged, forming a mold cluster. This allows for the efficient casting of multiple parts at once.
The mold is heated to burn out the foam pattern. The foam vaporizes, leaving behind a hollow cavity in the mold.
Molten metal is poured into the cavity, filling the space left by the foam pattern. After cooling, the ceramic shell is removed, revealing the final cast part.
Lost-Foam Casting Materials
Lost-foam casting offers precision in creating complex geometries with minimal waste. This process allows for a variety of high-performance materials tailored to specific application needs.
Common alloys like A356 and 319 provide high castability, excellent strength-to-weight ratios, and corrosion resistance. These alloys are ideal for producing complex shapes in automotive and aerospace applications.
Low-carbon and alloy steels, such as 4140 and 4340, are used for components requiring high tensile strength and fatigue resistance. Steel's ability to handle high-stress and high-temperature environments makes it ideal for industrial machinery and tooling.
Alloys like C90700 bronze and C26000 brass are chosen for their exceptional thermal and electrical conductivity and superior corrosion resistance. These alloys are used in electrical connectors, marine hardware, and valve components.
Gray iron and ductile iron (nodular cast iron) are preferred for their ability to absorb vibrations and handle heavy loads. Cast iron’s excellent fluidity during casting makes it ideal for engine blocks, brake components, and pipes.
Inconel and Hastelloy, known for their excellent high-temperature strength and oxidation resistance, are used in critical aerospace and gas turbine components that must perform in extreme thermal environments.
Alloys such as AZ91D and AM60B are used for their lightweight and high strength-to-weight ratios, which are essential for aerospace, automotive, and military applications where weight reduction is a key factor.
Minimize Waste in Prototype Production with Efficient Casting
Traditional casting methods create significant waste due to separate mold-making. Lost-foam casting minimizes this waste by using foam patterns consumed during casting. This approach eliminates the need for additional molds, reducing material consumption. The foam pattern burns away, leaving a precise cavity for the metal to flow into, ensuring that only the necessary material is used. This method is particularly advantageous for prototype production, offering efficient, low-waste casting solutions for intricate designs. Frigate’s Lost-Foam Casting process ensures accuracy and minimal material loss.
