Key Concepts
- -- Metal Flow Dynamics
- Describes how molten metal behaves as it flows into a mold, significantly impacting surface finish and defect formation.
- -- Solidification
- The process whereby molten metal cools and transitions to a solid state, which can influence mechanical properties and casting defects.
- -- Gating System Design
- Refers to the components and design of the system allowing molten metal to enter a mold, aiming to minimize turbulence and ensure quality.
- -- Riser/Feeder Design
- A design feature that compensates for shrinkage in solidifying metal, ensuring optimal feeding of liquid metal to the casting.
- -- Chvorinov's Rule
- A formula used to estimate the solidification time based on the volume and surface area of the casting, crucial for optimizing cooling rates.
