Desgin Guide for Injection Molding. Here are the basic guidelines for reference: 0.5 degrees on all vertical faces. 2 degrees works very well in most situations. 3 degrees is minimum for a shutoff. 3 degrees is required for light texture. 5 or more degrees is required for heavy texture.

Engineering Guidelines to Designing Plastic Parts for injection molding draft angle guidelines

Draft angles allow for removal of the plastic from the mold. Without draft angles, the part would offer significant resistance due to friction during removal. Draft angles should be present on the inside and the outside of the part. The deeper the part, the larger the draft angle. A simple rule of thumb is to have a 1 degree draft angle per inch.

2020-11-17 · Draft angle is one example. If a part does not have draft angle designed into it where needed, it may not eject from the mold cleanly and smoothly, and the part will have to be redesigned with proper draft angle. To help avoid costly and time-consuming design mistakes, we created a plastic injection molding design guide.
