Draft Angle


So that parts can be easily ejected from the mold, walls should be designed with a slight draft angle, as shown in the Exaggerated Draft Angle illustration. A draft angle of 1/2° draft per side is the extreme minimum to provide satisfactory results.

1° draft per side is considered standard practice. The smaller draft angles cause problems in removing completed parts from the mold. However, any draft is better than no draft at all.

Parts with a molded-in deep texture, such as leather-graining, as part of their design require additional draft. Generally, an additional 1° of draft should be provided for every 0.025 mm depth of texture.
