Possible defects:
Defect
Causes
Unfilled sections
Insufficient material
Low pouring temperature
Porosity
Melt temperature is too high
Non-uniform cooling rate
Sand has low permeability
Hot tearing
Non-uniform cooling rate
Surface projections
Erosion of sand mold interior
A crack in the sand mold
Mold halves shift
There are no these problems for us.
Uniform wall thickness will ensure uniform cooling and reduce
defects. A thick section, often referred to as a hot spot, causes
uneven cooling and can result in shrinkage, porosity, or cracking.
Corners
Round corners to reduce stress concentrations and fracture
Inner radius should be at least the thickness of the walls
Machining allowance
Add 0.0625 - 0.25 in. (0.16 - 0.64 mm) to part dimensions to allow
for machining to obtain a smooth surface.
