Die Casting Design Solutions
Die cast draft angle meant the taper or slope in perpendicular direction of the casting. Most of die-casting surfaces which vertical to the parting line of the mold require draft in order to the die-cast part easy get out of the core or other parts of the die cavity.
The shrinkage stress during the forming cooling shrinkage die casting process , which causes the casting stick to the die core and a resistance to mold release in the process of ejection of the casting from the mold.In order to reduce the resistance of releasing the casting from the core more easily, and prevent the surface of the casting and core are scratched by the friction caused from relative movement. In short the die-cast draft angle must be set on the side surface of the casting in the same direction as the release.
How to design and measure draft angle
Increase (Add) mass { draft} /Decrease (Reduce) {-draft} mass
Normally choosing is decrease mass to avoid interference is the best ( failure to install)
and add the mass for the part need cnc machining , reduce the mass without machining ,
How to measure the die cast draft angle
Aluminum high pressure die cast draft angle
normal 2 Degrees, min 1 degrees . Max draft is applied to a die casting part , you can get good quality die cast product and Dont worry about products all day.
Zinc high pressure die cast draft angleFor zinc part , we has experience in zero draft angle. we always try my best to meet customer requirement.
