Why Draft Angle in Die Casting is a must. In the process of die casting, having the correct draft angle combined in die casting molds is a very vital thing. It is one of the factors that will affect the entire quality of the die casting parts fashioned.
What is Die Casting Draft angle?

Did you ever notice that the sides of a cupcake pan are inclined in a certain angle towards the center of the pan? If you inspect the pan, the sides are not straight but rather slanted at a certain degree. With that as an example, draft angle in overall sense, is an angle unified into the wall of a mold, making the opening of the cavity a bit wider than its base.

Die Casting draft angle is the angle that is unified into the walls of the die casting mold permitting the die casting part to be effortlessly ejected from the mold.

Is draft angle in die casting molds really essential?

The justification behind the need for draft angels on die casting molds lies from the very nature of the die casting procedure – injection molding process -and also, the unavoidable issue of mold reduction.

Die casting manufacturing process for metal parts is done by pushing the molten metal into a mold cavity. These mold cavities are completed with toughened tools that have been machined to the net shape of the die casting parts.

The injection of the molten metal into the mold voids is a high-pressure process. The high pressure forces the molten metal into close contact with the walls inside of the mold cavities. The high-pressure packing of the surface of the mold’s cavities makes it hard to get the die casting part out of the mold. In short, the ejection process will be compromised.

With the above explanation, it is absolutely clear that draft angle is indeed a necessity.
