Overview | Interface | Density Type Pros Cons Forging » No interface » High density » High aspect ratio 1:100 » Expensive on cost Extrusion » Cost effective » No interface » Lower aspect ratio 1:23 Die Casting » Cost effective » Net shape » Less machining cost » Poor density » Poor heat transfer performance » Lower aspect ratio 1:15 Stamping/ Soldering » Cost effective » High fin » Too many interface » Un-reliable quality Skiving » High fin » Potential crack risk between fin and base Maching » Fliexible applications » Cost expensive » Long lead time Type Example Forge Insert Soldering Extrusion Forge Rating: Excellent Extrusion Rating: Good Die-Casting Rating: Poor Metal Injection Molding Rating: Poor
