Undercut
Posted on 01/01/2019 Category:
A feature on a part which requires a corresponding feature in the mould which is perpendicular to the direction of extraction. An undercut complicates the manufacture of a moulded part by making it difficult to remove the finished part from the mould, and often requires the mould tool to be designed to have a removable insert that releases the undercut face prior to demoulding the part.
