Injection molded knockout |
摘要 |
A technique is shown for injection molding knockout sections in plastic parts. Through the introduction of a weld line in a controlled manner, removable sections of any geometry may be incorporated in a part. By varying the weld line geometry, knockout forces may be varied over a wide range. An example of a circular knockout in polycarbonate material is shown.
