Using ejector pins properly on molded parts

In most cases,ejector pin placement is a relatively minor concern in the early phases of part design.Protolabs will propose pin placement when an order is placed and present a pin and gate layout for customer approval.At that time,Protolabs will address any questions or concerns and make changes,if necessary,to meet customer requirements.TENSILE AND MICROSTRUCTURAL CHARACTERESTICSset up has been developed in a conventional vertical milling machine (with a tool geometry of 20mm shoulder diameter,6.35mm as pin diameter and 5mm as pin length,tool rotation of 1800 rpm,linear traverse of 100mm/min) and obtained good FSW joints.Comparative study on Tensile and Micro structural characteristics of welded joints obtained fromTENSILE AND MICROSTRUCTURAL CHARACTERESTICSset up has been developed in a conventional vertical milling machine (with a tool geometry of 20mm shoulder diameter,6.35mm as pin diameter and 5mm as pin length,tool rotation of 1800 rpm,linear traverse of 100mm/min) and obtained good FSW joints.Comparative study on Tensile and Micro structural characteristics of welded joints obtained from
