• When using INSUBORD or FEXOBORD as riser sleeves, the heat-retaining and insulating effects of the sleeve during casting allow for much smaller risers than sand-mold risers. This results in easier product design, reduced machining costs, lower remelting costs,
  and fewer shrinkage defects.

• INSUBORD and FEXOBORD are board-type sleeves that can be rolled and shaped into the desired form, making them suitable for large or custom-shaped risers.

※ INSUBORD is an insulating sleeve, while FEXOBORD is an exothermic sleeve.
