Three Plate Extension Bushings FAQ

What is intended to interface with the back of the three-plate extension bushing assembly (in the spherical radius area)?

The injection machine nozzle tip. Be sure to choose a machine injection nozzle tip with an appropriately-sized spherical radius to match properly with the spherical radius that is located at the back of the 3-plate extension bushing assembly. Also, it is important to size the exit orifice of the injection machine nozzle tip to match the inlet diameter of the sprue in the 3-plate extension nozzle assembly.

Where can I find recommended installation instructions for the 3-plate extension bushings?

Machining and installation information is provided in the DME Mold Bases and Plates catalog. Additional installation instructions are provided packaged with the components. If you would like an electronic copy of the instructions, please contact us.
