  8. Design of plastic components - Wikipedia

    en.wikipedia.org/wiki/Design_of_plastic_components

    Draft angle design is an important factor when designing plastic parts. Because of shrinkage of plastic material, injection molded parts have a tendency to shrink onto a core. This creates higher contact pressure on the core surface and increases friction between the core and the part, thus making ejection of the part from the mold difficult.
