EXOTHERMIC SLEEVE

Heat and insulation riser sleeve, in contact with the metal liquid, through the heating agent burning heat, the metal liquid heat conduction effect, at the same time, the riser sleeve has a thermal insulation effect, so you can extend the solidification time of the metal liquid in the riser to a greater extent, forming a continuous and effective feeding effect on the casting. Thus, the volume of the riser is reduced, and the casting is supplemented, so as to achieve the purpose of improving the process yield of the casting and reducing the production cost of the casting.
