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 toAdvanced thermo treatment equipment, such as network heat treatment oven, multi-use thermo treatment oven, etc. 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.
