OEM Gravity Casting for pipe fittings

Gravity casting represents one of the oldest casting methods. In simple terms, gravity casting is pouring molten metal directly into a permanent or semi-permanent mould.

The first step is heating up the mould after the mould has been sprayed with a release agent spray. The use of the spray is to make sure the metal can be easily detached from the mould after cooling down.

Then the next step is pouring molten metal into the desired mould through a sprue. In the old times, the pouring process is normally operated manually which pose great danger to operation workers and low efficiency.

After the part is cooled down, the last step is to remove the mould and take out the product.
