Model Setup
Designate casting parts, gravity direction, gates, and components.
- Cast Part
  Define the casting parts, filling system, and gravity direction.
- Gate
  Identify predesigned gates, or create and edit virtual gates.
- Components
  Identify predefined components, or create virtual components (cores, chillers, risers, sleeves, overflows, the mold, coolers, and filters).
  - Core
    A core is used to create the interior shape of a model. It is commonly used in sand casting, but it can also be used in other processes.
  - Chiller
    A chiller is used to accelerate the solidification in a specific area of a metal casting mold.
  - Riser
    A riser is a reservoir of material built into the mold to prevent porosity resulting from shrinkage.
    - Add/Edit Riser
      If you haven't designed any risers in a CAD tool, you can create and edit virtual risers in Inspire Cast.
    - Designate Components as Risers
      Identify any risers you've already designed in a CAD tool.
  - Sleeve
    A sleeve is a sand component that is placed around a riser.
  - Overflow
    Overflows are cavities in the die that act as vents for air to escape and as traps for excess metal flow.
  - Squeeze Pin
    Squeeze pins can help prevent porosity in a finished part by compressing a particular region of the molten metal during its solidification.
  - Mold
    A mold contains the cast part and any casting components.
  - Cooler
    A cooling system is used in high-pressure die casting to provide heat dissipation and to maintain a constant temperature relative to the mold. This helps ensure tension-free cooling of the cast parts.
  - Filter
    A filter is a casting component applied to the gating system to catch impurities and to have flow control over the liquid as it passes through it.
  - Shot Sleeve
    In High Pressure Die Casting, a shot sleeve is a piston sleeve that advances the liquid in the chamber to the mold.
  - Crucible
    In Gravity Tilt Pour Casting, the crucible is the vessel in a vacillation machine that administers the liquid to the mold.
  - Stalk
    In Low Pressure Die Casting, a stalk is a riser tube through which molten material is forced into the mold.

Riser

A riser is a reservoir of material built into the mold to prevent porosity resulting from shrinkage.

It prevents porosity by providing molten metal to the casting as it solidifies, so that porosity forms in the riser and not the casting. After solidification, the riser is removed and the part is free of porosity.
