WebFeb 1, 2001 · From a technical point of view, valve gate technology enables the production of low-stress injection molding parts, which almost always meet the requirements of a very low vestige. As a result, the lower degree of stress when gating with valve gate systems becomes relevant. WebJan 1, 2013 · That means that we can control the shear rates by controlling the flow or the gate size. The flow rate is simply controlled by the injection speed of the molding machine. Gate size is easily changed too, but there are a couple of things to consider. It is important to determine how large of a gate vestige is acceptable. Does it need to be hidden?
