Cold runner injection molding systems consist of two or three plates contained within the mold. The system injects the plastic into the mold through the sprue and feeds the runners, which lead to the parts in the mold cavity. The simplest type of cold runner system consists of two plate molds, which has a parting line that separates the two plates. This system has the runner and part attached. You can only gate the part of its perimeter. An ejection system separates both the runner and part from the mold.

Three-plate cold runner systems consist of three plates. There are two parting planes that allow the mold to separate into three sections upon ejection of the part. The runner connects to a separate plate and only the part requires ejection. Three plate molds allow for greater design flexibility and allow flexibility for gate installation based on the requirements of the application. Both types of plates require the runner to be recycled and reground (or disposed of) to reduce waste, which adds to the cycle time.
