In the design of the Stool Mould, the draft degree refers to the degree to which the mold core can gradually become thinner. A precise depth is required to smoothly eject the casting from the mold, but since the depth is not constant and will vary according to the angle of the wall, the characteristics are such as the type of molten alloy used, the shape of the wall, and the depth of the casting. Will affect the processing process. The geometry of the mold also affects the draft. Generally, due to the risk of shrinkage, unperforated holes need to be tapered. Likewise, the inner wall also shrinks and therefore requires more draft than the outer wall. You can search for draft angles for more information about die casting mold design and manufacturing.

The fillet is a concave connection used to smooth angled surfaces. Sharp corners hinder the casting process, so many molds have rounded corners to form rounded edges and reduce the risk of production errors. Except for the parting line, the fillet can be added to almost any position on the mold.

Parting lines or parting surfaces connect different parts of the mold together. If the parting line is placed incorrectly or deformed due to working strain, the material may penetrate into the gap between the molds, resulting in uneven molding and excessive seams.

The boss is a die-cast knob and is used as a mounting point or support in the mold design. Manufacturers often add a hole to the internal structure of the boss to ensure that the wall thickness of the molded product is uniform. Metal is often difficult to fill deep bosses, so it may be necessary to use fillets and ribs to alleviate this problem.
