Salt Core Advantages
Precision for Complex Internal Cavities
Water-soluble salt cores enable complex internal cavities and offer greater freedom in passage design, helping reduce the need for mechanical core removal around delicate cast structures.
Complex Cavity Formation
Water-Soluble Core Removal
Flexible Component Design

Complex Internal Passages
Engineered for Internal Cooling Passages
From aluminum piston cooling galleries to other complex casting cavities, salt cores help form internal structures that are difficult to reach through conventional machining.
