General Information about Die Casting Draft Angles. Draft Angle is the sloping required in manufacturing aluminum die casting products. Because it facilitates ejection, this feature is often highly considered by aluminum die casting manufacturing companies.
Die Casting Draft Angles apply to both the pattern and the castings. Pattern Draft Angle is the considerable degree of tilt on the surface of the pattern. It allows the ejection of the casting from its mold. Casting Draft Angle on the other hand is the draft angle on the casting itself. It is the actual sloping seen on the castings.
Although the computation of draft angles is frequently generalized, the interior and the exterior surface of the die cast wall are highly considered. The draft angle recommended for the interior wall is twice as much as the external surface to facilitate ejection when the aluminum alloy harden and shrink.
In some instances, most particularly in the production of precision metals used by electronics industries, draft angle considerable varies. It must be specified in the design in order to guarantee efficient and effective performance of electronic gadgets, appliances, furniture and lighting fixtures etc. which uses these materials in their manufacturing process.
Draft Angle is also considered in designing the parting line and determining the parting line tolerance. The parting line is the point where the two halves of the casting mold meet. In most cases this line defines the internal and external surfaces of die cast parts. Minor errors in die casting applications includes errors or faulty in parting line designs.
Tons of aluminum products worldwide are made efficient just because a simple feature like draft angle was never taken for granted.
