NORTH STAR EQUIPMENT Expansion Box for 4" Extruders


INCLUDES: The expansion box, die retainer ring, hex wrench, three piece spacer board and all hardware.

                The Expansion Box is an extruder accessory that allows  the  user to produce larger extrusions from their North Star 4” extruder.  This is accomplished by adapting the bottom portion of a detachable box to fit North Star’s selection of 6 inch Dies. We have a selection of stock 6” dies available & custom dies are quickly made and inexpensive.

Whats Included in the Kit

          The #940 Expansion Box includes the Expansion Box, Die Retainer & mounting bolts, hex wrench, one piece spacer board, & lag bolts

Construction

                 The expansion box is made of high quality aluminum. All the mating surfaces of the expansion box are machined flat for a tight seal. The die retainer mounting ears have steel inserts for the bolts to screw into. The ears with slots of the expansion box are machined to slide easily onto and out of the extruder. The die retainer ring and the hardware is made of steel. All outside surfaces are powder coated for a durable lasting finish.

6" Extruder Dies

                 The 6" extruder dies are made of 3/4" HDPE (High Density polyethylene). Which is extremely wear-resistant and completely non-contaminating.  The top edge of the die cavity is beveled to compact the clay as it passes through, giving a crisp, more solid extrusion.  In the hollow dies, there is a bevel on both the interior and exterior portions under each side of the bracket (which holds the center of the hollow dies) that helps the extrusion to "heal" after is has been cut apart by the bracket.  This bracket fits into a slot machined into the top of the hollow die and is held in place by the barrel of the extruder.  If a hollow die is mounted in place, the center part of the die is in exactly the right place and the wall thickness will automatically be even all the way around. In general, the walls of extrusions 3-1/2 inches OD or less are 1/4 inch thick, while larger pieces have 5/16 inch walls. We have a selection of stock 6” dies available & custom dies are quickly made and inexpensive.
