Jul 24, 2018·What is a vacuum void? Shrinkage in the interior of a plastic part is often called a vacuum void. It is generally found in an area where the plastic is very thick or where multiple channels come together to form a rib or a wall. These areas are especially susceptible to uneven cooling or shrinking, which is the underlying cause of voids.

Plastic Part Design Guidelines for Injection Molding Plastic Parts

Gussets In Plastic Parts Gussets are used in plastic parts to increase part strength in the required section. But the location of gussets prevents direct venting in mold steel. Therefore Gussets in plastic parts should be designed in a way that they should not create any venting or filling problems. 6. Draft Angle in Injection Molded Plastic Parts
