Key Features & Advantages

Excellent Design Freedom & Complex Geometry

• Lost foam casting allows production of intricate parts with undercuts, thin walls, internal cavities and complex features without the need for cores or parting lines.

• Designers have greater flexibility compared to traditional sand casting. 

Near-Net Shape with High Precision

• The foam pattern directly mirrors the final part, enabling tight dimensional accuracy and consistent repeatability.

• Surface finish can reach high smoothness, reducing machining and finishing work. 

Cost & Material Efficiency

• Reduced machining allowances and elimination of cores help lower production cost and minimize material waste.

• Dry sand used in the process can be reused, enhancing sustainability. 

Improved Casting Quality

• No parting lines or draft angles are required, so casting defects such as flash, burrs and mismatched surfaces are reduced.

• High dimensional integrity makes castings easier to finish. 

Suitable for Variety of Alloys

• Lost foam casting works well with ductile iron, gray iron, cast steel, stainless steel, aluminum and other alloys, making it versatile for both ferrous and non-ferrous applications. 

Common Applications
