Accede Mold & Tool of Rochester, New York, recently selected Polyshot Corporation to supply them a two-shot hot runner system for a very interesting mold they completed for an high volume agricultural component. The mold was an 8+8 cavity mold (8 out), with the first shot running black polycarbonate and the second shot running white polyurethane. The hot runner used was a Polyshot 050M Valve Gate System with two fully independent manifold systems housed in one hot half system.

Of particular interest in this mold is the use of Accede Mold & Tool’s internally developed, rotating two-shot core section system. This system eliminates the need to rotate the entire ejector side of the mold in two-shot molds. The elimination of the normal rotating platen is a huge cost savings to the molder and the rotation of the core section only reduces the overall cycle time.

As shown in the image above, upon mold opening, the ejector core section advances out of the mold. Through some truly amazing engineering, with the center core extended, a stripper plate mounted to the face of the rotation core is moved forward ejecting the finished parts. The center core then rotates 180 degrees, the mold closes and the cycle repeats itself.

A visit to Accede’s internal two-shot testing facility to witness this truly impressive chain of events is a trip worth making. Contact Mr. Roger Fox at Accede Mold & Tool for further information and to set up a tour.
