Gravity Casting Parts Design Guideline
This guideline offers industry standard values for gravity casting parts to optimize metal flow and solidification while minimizing shrinkage, porosity, and production costs, ensuring high-quality, dimensionally accurate castings.
|
Design Element |
Suggestions (Industry Standard Values) |
Reasons and Benefits |
|
Wall Thickness |
Typical range: 3 - 8 mm (ideal ~5 mm) |
Ensures proper metal flow, solidification, and reduces risk of shrinkage and porosity. |
|
Corner Radii |
Minimum internal radii: 2 - 4 mm |
Reduces stress concentrations, improves flow characteristics, prevents cracking. |
|
Draft Angles |
Draft angle: Typically 2° - 4° per side |
Facilitates easy part removal from the mold, reduces mold wear and surface imperfections. |
|
Fillets |
Minimum internal fillet radii: 2 mm |
Promotes metal flow, reduces stress concentration, and improves structural integrity. |
|
Hole Sizes |
Minimum hole diameter: 3 - 5 mm |
Ensures mold filling, prevents incomplete castings, and reduces defect risks. |
|
Undercuts |
Avoid or minimize undercuts |
Simplifies mold design, reduces complexity, and minimizes production costs and defects. |
|
Surface Finish |
Typical gravity casting roughness: Ra 6.3 - 12.5 µm |
Provides a balance between achievable surface quality and cost efficiency. |
|
Tolerances |
Typical linear tolerance: ±0.5 mm per 25 mm |
Represents achievable accuracy; tighter tolerances typically increase cost. |
|
Text and Logos |
Minimum text/logo depth/height: ≥ 1 mm |
Ensures visibility and clarity in casting, suitable for gravity casting surface finish. |
|
Ribs and Gussets |
Thickness approximately 60 - 80% of adjacent walls |
Adds structural strength without excessive shrinkage, porosity, or stress concentration. |
|
Parting Line |
Position at widest cross-section, simple and flat |
Reduces flash and defects, simplifies mold construction, and improves cosmetic quality. |
|
Machining Allowance |
Typical allowance: 1.5 - 4 mm |
Allows sufficient material for accurate machining and achieving final dimensions. |
