This is one of the most commonly used ejection systems known. This is the most versatile type of system is because it is used on the all shapes of parts. While the two-plate system can be used on both the round and non-round parts, it is used more on non-round parts. Round parts will lend themselves more to a less expensive type of stripper ejection. The goal of any ejector system is to eject the part automatically without distortion. The placement of pins becomes important in design to minimize the potential for distortion. In more sophisticated parts this ejector system can be used in conjunction with a stripper plate or plate sequencing to enhance the ejection so no distortion will take place.
