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.
