Lost Foam Casting Process

Lost Foam Casting is an advanced precision casting process offered by Tech Line Engineering, ideal for producing complex metal components with intricate geometries and excellent dimensional accuracy. This process uses expandable polystyrene (EPS) foam patterns that evaporate during molten metal pouring, eliminating parting lines and the need for cores.

Casting Size Range Small to large-sized components
Material Compatibility Cast Iron, Ductile Iron, Aluminum Alloys
Production Volume Low to medium-volume production
Surface Finish Near-net-shape finish with minimal machining requirements
