Advantages
Disadvantages
Fabricated steel
→ Lower Cost than cast and CNC molds.
→ Very large molds can be made at an affordable cost.
→ Lead times are rapid depending on complexity.
→ Good surface finish is achievable.
→ Aluminum, steel or stainless steel can be used to build the mold.
→ Tolerances are not as good as cast and CNC molds.
→ More maintenance is required when compared to cast and CNC tools.· Complex geometry is challenging to recreate
Cast aluminum
→ Complex Geometry is achievable.
→ Cost is relatively low compared to CNC molds.
→ Excellent detail is achievable.
→ Good tolerances.
→ Cast molds are durable and require less maintenance than fabricated molds.
→ Small and large parts can be molded from cast tools.
→ Porosity may occasionally appear which can be easily corrected
CNC aluminum
→ Complex Geometry is achievable.
→ Excellent surface appearance.
→ Very good tolerances.
→ Excellent detail.
→ Good heat transfer.
→ Very good durability.
→ Quick lead times.
→ Fine parting lines.
→ No Porosity.
→ Higher cost than cast and fabricated molds.
