Exothermic Sleeves

Exothermic riser sleeve, with low density, accurate size, good exothermic effect, which is suitable for the feeding of iron casting and steel casting. High performance to feed castings in iron, steel and all the alloys of these metals, moulded in sand and other systems.These features combine to deliver consistently high levels of feed performance, easy riser removal and reduced tendencies for under riser cracking over a broad range of casting applications. It can be inserted into the sand mold after modeling or matched with the sand core and put into the sand mold. It can effectively improve casting yields and enhance the density of casting, reduce the cleaning and welding repair work. These sleeves provide healthy pieces, without porosity and without reaction of the metal with the sleeve.
