MINI - RISERS
ARROSI DOES NOT USE (due to its direct causal relationship with cancer):
  • Asbestos - Asbestos.
  • Refractory Ceramic Fibers.

  • No other material classified as carcinogenic (neither possible nor probable) by IARC (International Agency for Research on Cancer - www.iarc.fr).

APCTech Mini-Risers

APCTech mini-risers are low density and HIGH PERFORMANCE sleeves. Its design, with thicker walls than conventional sleeves, and its optimal exothermic-insulating formulation give them an exothermic module much higher than that of those.

High performance to feed castings in iron, steel and all the alloys of these metals, molded in sand and other systems. The mini-risers provide healthy pieces, without porosity and without reaction of the molten metal with the sleeve.

Type of molding:
  • Manual and automatic
  • Pressure and shaking
  • Shooter/Blower
  • Sand blasting
  • Blown by explosion or impact.

Molten metal:
  • Steel (carbon, high and low alloy, stainless, Hadfield)
  • Iron (Malleable, Nodular, Gray, high and low alloy)
Available with sand and metal retractable breaker cores.
