Precast Concrete Baluster EPS Foam Mold

Using a the hot wire 8700 CNC and hot wire 3000 Shaper and expanded polystyrene (EPS) foam, a custom architectural precast concrete baluster mold is created. This video shows it being prepared with an epoxy hard coat and poured. This technique applies to decorative and ornamental architectural concrete, cultured stone, and GFRC applications.

What is the cost of this machine?? and what skill set/experience you need to have to operate this machine. Also please guide as to how many repeatitions this type of mould can handle??

@mqaslam We used the hot wire CNC machine (8300, 8600 or 8700) for the twisted body and the square base and top, and we used 3000 foam shaper for the rounded profile on the top and bottom. We also have a dedicated machine for typical balusters (2000 Lathe).

Please contact salesinfo (at) hotwiredirect (dot) com to get a current prices. Software is not too complicated, especially since we cover everything in training.

With the epoxy it could do 10-20 repetitions approx, raw foam only 5.

The twist part was cut on the CNC machine using a straight wire while the foam was on the turntable-rotating. The round top and bottom cuts were done on the Shaper machine.
