LOST WAX INVESTMENT CASTING

For smooth surfaces, fine internal features, thin walls and small- batch production.

CENTRIFUGAL CASTING

ideal for producing components that demand superior strength, low porosity, and uniform grain structures. Vertical centrifugal casting is particularly suited for complex parts such as impellers, step-difference ears, elevator gears, and injection molding nuts, while horizontal centrifugal casting is well-suited for rings and tubular shapes like engine liners or pump components.

GRAVITY CASTING

Provides a valuable solution for clients who require large-scale production and faster manufacturing rates for their products.

SAND CASTING 

For clients who need to cast large components in small batch, low volume production, green and resin sand casting is an excellent choice.

FORGING CAPABILITIES
