The MPC 420 Series Slot Insulating Machines include common and graded slot insulators for horizontal or vertical load/unload. We can provide the right insulator to fit your application from our extensive selection of models and options.

The vertical style machine can be operated manually or supplied with an automatic load/unload MPC robet for semi or full automation. The turret on the horizontal style machine permits the operator to unload and load the insulator while the machine is insulating another part.

MPC has been providing slot insulating machines worldwide to the electric motor industry for four decades. Our slot insulators have earned a reputation for providing exceptional quality and dependability.
