Draft angle injection molding

What is the draft angle? The draft angle is the amount of taper for molded or cast parts perpendicular to the parting line. It can be measured in degrees or mm/mm (in/in). Why Draft angle injection molding? Reduces the chance of damage to the part due to friction during release [...]
