Summo Series

summo1and2-iso.jpgsummo-button.jpgAir Poppets from David Wolfe Design, Inc. are designed to relieve the vacuum created inside a mold either upon the mold opening or the molded part ejecting. Introducing air pressure to the mold cavity encourages the molded part to stay on the desired half. Using air poppets upon ejection, assist deep draw parts for easy removal.

The Summo & Summo-II Series are perfect for abusive, heat compression manufacturing scenarios. Click here for installation and removal instructions on the Summo-II series.
