|
One-Piece Structure
|
- Eliminates assembly and fasteners
- Reduces purchase order administration time and costs
- Reduces money tied up in inventory of parts needed for fabrications, which leads to an overall lower price
- Complex dimensional and/or metallurgical parts with aerodynamic surfaces

|
Sand Core Mold Process
|
- Permits the ability to produce complex geometric shapes and designs that would otherwise be impossible to create
- Allows for the capability to produce large castings
- Flexibility in design to fit any envelope
- Ability to add features at little or no additional cost
- Accommodates variety of size
- Easy to create internal passageways

Internal Cores
|
- Significantly decreases part weight
- Dramatically reduces part pricing
- Allows for metal to form complex structures that would otherwise be unattainable using any other method
- Eliminates metal inserts and/or tubes
