Typical Tool Building Methods

Cast (Aluminum) Good for intricate designs and complex shapes Good consistency/repeatability for multiple molds Can be updated and refurbished many times Must be made from a pattern

CNC Machined (Aluminum) Tighter tolerances Excellent consistency/repeatability for multiple molds Suitability of a design may be limited by machining capabilities

Fabricated (Stainless Steel & Aluminum) No pattern neededDesign features may be limited May not be suitable for multiple tool projects
