Project Features:
Main Challenges:
　· The PPS+50%GF material requires high molding temperature and needs a very good heating system for the mold.
　· The part inner thru hole is a diameter of 30mm and a length of 654mm, the slider molding for the inner hole needs to be worked
　 very well and keep the good part quality.
　· Customer does not like the ejector mark on the external surface.

Our Solutions:
　· Several layers of water lines were drilled to help the mold get enough heat during the molding, the mold was worked with
　 two mold heaters together during the molding.
　· We made a special kiss-off structure for the two sliders kissing and enhanced the support in the two sliders' ends.
　· The mold was designed without ejector pins or ejector plates. The part was released by the core moving back, a similar principle as
　 plate eject but in a different way. This makes the part molded without any ejector marks that satisfy customer requirements.
