The dimension of desired casting is taken for drafting purpose in order to produce an accurate 3D
illustration to be verified.
2. Pattern Making
A 3D model with the actual dimension of the desired casting is constructed out of wood once the
design has been verified.
3. Moulding & Core Making
The mould is made in two halves in a metal box for support which may include additional pieces of
sand known as cores to form internal shapes.
4. Melting
Various types of raw materials are melted conforming to the specification required to suit the
function of the casting.
5. Pouring
The molten metals are poured into the mould cavity through the running system consisting down
sprue, runner bar and ingates. Feeders are used to provide a reservoir of molten metal to compensate
the shrinkage in volume as the metal solidifies.
6. Sand Knockout
Once the metal has solidified, the sand mould is disintegrated to extract the casting.
7. Shot Blast
The casting extracted from the sand mould is shot blasted to remove any adhering sand and scale
left from the sand knockout process.
8. Heat Treatment
There are certain types of castings which need to go through the heat treatment process to harden,
stress relieve or to make the structure of the casting more uniform.
9. Feeder Removal
All runner, feeder and any surplus metal are cut off using the oxy cutter.
10. Gouging
Gouging is a mechanical method where the tip of the carbon electrode melt the contacted area of the
workpiece and the molten metal is blown away by high velocity air jet. This technique is used to
remove fins, riser and defects from casting.
11. Welding
The welding process is mainly used to repair casting when casting defects are discovered after the
part is machined.
12. Grinding
The grinding process is commonly used on casting to remove material on the surface
creating a flat surface.
13. Painting
We use the wet painting technique where liquid paint is sprayed onto the surface of the casting
while the casting is being rotated to ensure full coverage.
14. Packing
Once the product has passed the quality control standard, it will be carefully packaged to prevent any
possible damage and loaded for shipping.
15. Logistic (Dispatch)
The product within the shipping container will be dispatched to the customer once it has arrived at
its final destination.
