WebbWhen designing a part, apply as much draft angle as possible—a general rule of thumb is 1 degree of draft per 1 inch of cavity depth, but that can change with the aforementioned factors. Try following these general guidelines: 0.5 degrees on all vertical faces is strongly advised. 1 to 2 degrees works very well in most situations. WebbThe most commonly tested shape is a die cut C dogbone specimen, which calls for an overall length of 115 mm (the gauge length being 25 mm), width of 6 mm, and thickness of 3 mm. Thickness of the specimen must be measured three times, with the median value being the accepted value.
