Lost Foam Casting 50-100 Mesh Ceramsite Sand Physical Character

Lost Foam Casting 50-100 Mesh Ceramsite Sand Main Advantage

1	Stabe quality on the chemical composition
2	Perfect grain round shape and various grain sizes
3	High gas permeability
4	High temperature resistance
5	Good break down and fast curing and good release
6	Perfectly round shape with higher fluidity improves fill-in efficiency while reducing the resin level
7	Smooth surface of spherical shape greatly improves collapsibility after pouring
8	Very low thermal expansion ensures fewer or no casting defects such as veining and deformation
9	Excellent thermal conductivity and heat absorption capacity close to that of Zircon
10	Superior refractory equivalent to Zircon and Chromites

Lost Foam Casting 50-100 Mesh Ceramsite Sand Applications

1	Widely used in foundry technique like resin-bonded sand, sodium silicate sand, and clay- bonded sand for sand core and casting mould making
2	Replace chromite sand and widely used in sand core making like jacket core, oil duct core, tappet core of engine.
3	Replace chromite sand for steel casting facing sand and sub-layer of molding sand (backing sand).
4	Widely used as dry sand and sand box for EPC process and V method of casting processes.
5	Widely used as the main raw materials of advanced refractory products (Ladle drainage sand,gravity casting material, casting coating, etc.).
6	Widely used as cleaning sand for copper and aluminum alloy castings.
