Return Pins, Stop Pins and Sprue Puller Pins
Return Pins are used to ensure correct return of the ejector assembly to the home position. DME return pins are precision-ground from superior quality hotwork die steel. Stop Pins arrest travel – preventing excessive wear and possible housing damage. The Sprue Puller Pin removes material from the Sprue Bushing at the end of the molding cycle. It’s positioned directly below the Sprue Bushing and is retained between the ejector bar and ejector retainer.
Features supplied as standard unless otherwise specified.
