The Polyshot P Microbushing was designed to be installed in small molds such as those used in the Nissei HM7 injection molding machine and others. Its small size and flow path makes it very well suited to the very small shot sizes used in these applications.

Polyshot P-Microbushing is installed into a gate well detail machined in the “A” half of the mold by the mold maker. This bushing can also be fitted with a PR Gate Interface Cap, to allow installation into a .625″ diameter hole machined in the “A” half of the mold. The PR configuration will leave a slight “ring” witness mark if gated directly into the part surface.
