The right draft angle

Choosing the draft angle is crucial. You should attempt to offer the greatest degree for the vertical feature. Its function is to assist in the removal of the part from the tool. With female features, they should have a 1.5 to 2 degree draft angle at minimum. Just remember that you’ll have to increase this for a deep texture. For male features, go for a 4 to 6 degree scope. However, if there is a deep feature or rougher surface texture, you will once again need a bigger draft angle.

Quality undercuts

vacuum formingSomething else you must consider is how to create quality undercuts. These are features that extend into or from the tool’s exterior. In certain instances, this might prevent you from detaching the part from your tool. For this reason, it’s ideal to go for undercuts that don’t exceed 15mm in depth. Whenever you create designs for your undercuts, you must always keep the draw ratio in mind.
