Plasma Arc Cutting
- Components are drawn using CAD software.
- Exported as DXF file.
- Sent to a nesting program which arranges components in a way that creates least waste.
- Sheet metal is placed on the bed of the cutter.
- Design is cut out using a high heat plasma arc.
- Components are finished and ready for machining.
Sand Casting
- A metal box is partly filled with sand and resin.
- A shape made of wood or plastic is placed on to the first layer.
- The box is filled up with the rest of the resin and sand.
- The mixture is left to dry and the shape mould is taken out.
- Molten metal is poured into the mould and left to cool.
- The sand is taken away, leaving the shape formed in metal.
- The piece is now ready for polishing.
