Product Description
Molding Sand is a kind of refractory particle with diameter of 0.020mm~ 3.350mm, mainly made of Al2O3@SiO2. It is ball-shaped particle made from bauxite by high-temperature
Melting in electric-arc furnace, spraying and cooling.
Features of New Ceramic Sand
1. As solid spherical sand, the surface area is small, which can reduce one third the amount of binder (resin, or R2O@nSiO2 etc. ). Good fluidity, easy to fill and close-grained without dead space when producing sand mould and sand core. Low gas evolution and high permeability, can reduce defects, increase the rate of finished products and lower the cost of casting material.
2. High refractoriness, low coefficient of thermal expansion with good stability under high temperature. During the process of foundry, the sand is easily dispersed, easy to clean, no sintering and gluing on the casting, which reduce the deformation of the casting, reduce the clean-up work and lighten labor intensity.
3. Reasonable grading composition of the particle, improve the strength of casting mould and sand core.
4. The bulk density of ceramaic foundry sand is 1.79-1.87g/cm³ , lower than the bulk density of chromitesand (2.5~2.9g/cm³ ), the sand core is easy to move with light weight, and also can reduce the usage amount of sand.
5. The sand is man-made by melting under high temperature, so it has stable chemical parame ter, unified physical properties. Neutral material, both acid and basic binder agent can be used.
6. High durability and high recalamition yeild.
Applications of New Ceramic Sand
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.

Quality Control of New Ceramic Sand
Raw Material Selection:
To ensure the quality of our raw materials, we only purchase our raw materials from our long-term trusted suppliers. With every purchase, our quality control staff performs the first inspection at our supplier's site. Once the raw materials arrive at our facility, our quality control team performs a second inspection on the batch. Each time raw materials enter our facility, they are inspected again prior to being accepted.
Process Quality Control:
From raw material to final product, our process control inspectors ensure that our procedures are consistently and correctly applied each step of the way. In addition to rigorous process control, our quality control team inspects the output of each process to ensure material quality and consistency. In each of our workshops, our employees understand that the output of their workshop is the input for the next manufacturing department. Therefore they have been trained to always carefully inspect the previous workshop's work and be responsible for their own output.
