Variety of Side Actions in Injection Molding
Inserts placed to the mold to provide undercut geometry are known as Injection Molding side actions. A straight-pull mold, which separates the two halves of the mold and ejects the component, is unable to manufacture undercut features, which are perpendicular to the main separation line. The undercut feature is created by allowing the material to flow past side actions that are introduced to the mold. To enable portion ejection, the side actions must subsequently be eliminated, either manually or automatically. Side actions are advantageous because they expand the range of possible part geometries. However, side actions may significantly raise the cost of Injection Molding China manufacturing, so it's useful to think about whether you need them or whether slot characteristics can help you avoid them.
