What the product is

The product description calls Ceramcast a special artificial ball sand for the foundry industry. It is offered as a substitute for Japanese Cerabeads sand, fused ceramic sand, chromite sand, zircon sand and silica sand. Its mineral composition is listed as mullite plus corundum, and its grain shape as spherical.

Step 1: Define your buyer requirements first

Write down your own constraints before you compare data sheets:

• Process: resin-coated sand, cold box, green sand, no-bake, lost foam, 3D sand printing or another route.
• Alloy and pouring conditions: steel, iron, alloy, aluminum or copper castings, and how much thermal load the mold or core takes.
• Binder chemistry: acid-catalyzed or alkaline resin systems.
• Grain fineness: the AFS number or mesh distribution your current sand uses.
• Reclamation: whether you reclaim sand mechanically, thermally or not at all.
• Cost basis: whether you buy sand by weight and how many molds or cores each batch has to produce.

Step 2: Compare against the published specifications

How these values map to selection criteria

• Refractoriness and thermal load: The description says refractoriness of ≥1800 ℃ gives better adaptability in higher-temperature casting conditions and lowers defects such as sand burning-on, sintering and veining. This matters most if burn-on or veining is a problem in your heavier or hotter pours.
• Thermal expansion and dimensional accuracy: The published expansion figure is 4.5–6.5 × 10⁻⁶/K (RT–1200 ℃). The product description links low expansion to fewer defects and better dimensional accuracy. Compare this figure with the data for the sand you use now.
• Grain shape and permeability: The description links the spherical grain and an angular coefficient of ≤1.1 to better breathability (permeability) and casting surface accuracy, as well as good flow and filling.
• Bulk density and yield by weight: The bulk density of 1.45–1.6 g/cm³ is described as similar to silica sand. According to the manufacturer, the same weight can produce about 25% more sand cores than fused ceramic sand. Check this against your own core volumes and binder ratios.
• Binder compatibility: The product is described as neutral (pH 6.6–7.3, acid demand <1 ml/50 g) and suitable for both acid and alkali resins.
• Reclamation: The description states a recycling rate of up to 98% and lists both mechanical and thermal reclamation. Your actual yield depends on your own equipment and process.
• Consistency: The supplier describes the composition as uniform, with stable properties and uniform color.

Step 3: Select a particle size grade

The description states that the particle size distribution can be customized to your requirements. The published reference grades and their AFS numbers are:

Ask for the full mesh distribution (20 to 270 mesh and pan) for the grade you are considering. Compare it with the distribution your current molding or core process is set up for.

Step 4: Confirm process and alloy fit

The product description lists these applications for Ceramcast:

• Processes: resin-coated sand, cold box sand, green sand, 3D sand printing, lost foam casting and no-bake sand.
• Castings: steel, iron, alloy, aluminum and copper castings, including high-end sand casting.

If your process or alloy is not on this list, this information does not show that the product will fit. Ask for technical confirmation or arrange a trial first.

When this recommendation may not apply

• Your process is outside the listed applications, or your specification needs a property that is not published above.
• You need certifications, test reports or compliance documents for your market. The materials reviewed here include none, so request them separately.
• Your purchase decision depends on price, lead time, packaging or minimum order quantity. None of these are covered here, so confirm them directly with the supplier.
• The published values are product description data, not results from your own process. Benefits such as fewer defects, the yield compared with fused ceramic sand, and the reclamation rate should be checked in your own foundry trials.

Questions to send before purchase

1. Which grade code and mesh distribution do you recommend for my process and alloy?
2. Can you provide batch test data for the properties listed above?
3. Can you supply a sample for a trial in my molding or core line?
4. What are the commercial terms (price, packaging, lead time) for my destination market?

Buyers in the United States, Europe, the Middle East and Southeast Asia should also confirm any import or documentation requirements for their region directly with Shenghuo New Material Technology Co., Ltd.
