Casting describes the process of pouring a material in liquid form into a mould - e.g.
- Metal Casting - Sand Casting, Die Casting and Lost Foam or Investment Casting
- Resin Casting - such as using clear polyester resin to encapsulate objects
- Plaster Casting - to make 3D copies of animal tracks for example
- Cast Concrete - used to make components for the construction industry for example
Features and Uses
It is possible to consider that almost any object can be made by either:
- Reforming Materials - e.g. by Casting, Thermoforming, Injection Moulding, Forging, Laminating
- Addition or Fabrication - e.g using Wood Joints, Adhesives, Fixings and Fastenings, Welding
- Subtraction - or material removal by: Cutting, Carving, Machining
Note: Throughout the articles on Casting, casting in aluminium only is assumed. In the experience of DT Online this is best done such that the mould is in the top box (i.e. Cope) and that a large diameter parallel Runner Sprue is used with no Riser which in effect ‘pressure feeds’ the mould to produce good quality castings. For this reason there may be some mismatch regarding the positions of Cope and Drag as compared with more conventional texts.
