FBOIII

The FBO Flaskless Molding Machine was developed for higher quality molds, increased productivity, and greater profitability. In the space occupied by similar older equipment, the FBO reduces mold shift problems, saves more spill and strike-off sand, and achieves greater molding consistency. Few machines in the foundry industry have generated the excitement of Roberts Sinto’s FBO. The series offers 6 different flask sizes; 14” x 19”, 16” x 20”, 20” x 24”, 20” x 26”, 20” x 28” and 32” x 32”. Each model has independently variable cope and drag heights.

FEATURES and BENEFITS:

  • Touch Screen
  • Programmable Controls With Diagnostics
  • Virtually No Spill Sand or Strike-off Sand
  • No Pits
  • No Special Bottom Boards
  • Mold To Mold Consistency
  • Maintenance Friendly
  • Horizontally Parted
  • Programmable Hydraulic Squeeze
  • Quick Pattern Change Features
  • Drag Mold Shuttle for Coresetting
  • Instantly Programmable Mold Height

A system has been incorporated where the drag mold automatically slides out, allowing easy access for coresetting, letting the operator perform his job safely and comfortably. An optional core setter is also available to allow for improved production rate.

A touch-reactive control panel has been added to the operator station, giving operational instructions, diagnostic data and warnings. Preprogrammed operations can be carried out from the monitor screen. The next stage of operation can be chosen simply by touching the screen. Changes in mold height, squeeze pressure and blow time can also be made with a simple touch.
