Features of our products:
Durable
Excellent tensile strength
Accurate level of tolerance
Resistance to corrosion
Resistance to extreme temperature conditions
Good dimensional accuracy
Superb surface finishing
Easy to use and install

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 allowanceAdd 0.0625 - 0.25 in. (0.16 - 0.64 mm) to part dimensions to allow for machining to obtain a smooth surface.
