| Conclusion | Flat-mouthed graphite crucibles are better suited for smelting processes that require repeated charging, prolonged heat retention, and stirring to remove impurities. They are the preferred choice for gold and silver refining, alloy formulation, and laboratory research and development. |
| Inner diameter | 20 mm-300 mm; height: 30 mm-500 mm (customizable to any specifications) |
| Precious Metal Jewelry Casting Industry | Suitable for the smelting, ingot casting, and jewelry processing of precious metals such as gold, silver, and platinum. Thanks to its high purity and low impurity content, it fully preserves the purity of precious metals. The non-stick inner surface minimizes waste of valuable raw materials, and the flat-bottomed design facilitates manual handling, making it an essential consumable for jewelry manufacturers and custom jewelry workshops. |
| Laboratory Research and Testing | Designed for high-temperature chemical analysis, ash content testing, sample fusion, and sintering experiments on new materials in universities, research institutes, and testing laboratories. It offers excellent chemical stability, does not contaminate experimental samples, provides precise experimental data, and its resistance to temperature fluctuations makes it well-suited for intermittent laboratory operations. |
| Small-scale precision casting | Ideal for precision melting and molding of small hardware castings and alloy components, this process offers high mold accuracy and excellent melt fluidity, effectively reducing defects such as porosity and imperfections in castings and improving the yield rate of precision castings. |
| Packaging | export standard wooden case. |
| Delivery Detail | 15~30 working days after confirming order. |
| Sea Port | Shanghai or other port of China Mainland. |
| Parameter Items | Standard Specifications | Notes |
|---|---|---|
| Product Material | High-purity synthetic graphite | No clay impurities, high purity |
| Graphite Purity | 99.9%-99.99% (optional) | Customization available for ultra-high purity |
| Product Density | ≥1.73 g/cm³ (customizable high-density options available: 1.78-1.90 g/cm³) | The higher the density, the better the strength and durability. |
| Ash Content | ≤0.3% | Eliminate material contamination |
| Temperature Range | Air environment: ≤600°C; vacuum/inert environment: ≤3000°C | Stable performance at high temperatures |
| Coefficient of Thermal Expansion | Very low | Resistant to sudden temperature changes; less prone to cracking |
| Surface Treatment | Mirror polish / Anti-corrosion coating (optional) | An antioxidant coating can extend the service life |
| Structural Styles | Straight-sided with a flat bottom for stability | Compatible with a wide range of devices |
| Comparison Items | Flat-Mouthed Graphite Crucible | Graphite crucible with spout |
|---|---|---|
| Ease of loading | Large opening allows for direct feeding of chunked or sliced ingredients | Due to the size of the feed opening, large pieces of raw material must be pre-processed. |
| Mixing Performance | The carbon rod/stirrer can be inserted vertically | Due to the angle of the mouth |
| Sealed | The flat lid fits tightly, reducing oxidation | The mouthpiece does not seal completely |
| Tipping control | Requires a tool for pouring | Precise pouring with a spout |
| Applicable Scenarios | Batch melting, extended holding time, and processes requiring stirring | Continuous casting, small-batch precision molding |
| Metal loss | Lower (steam loss is reduced by 15-20% when covered) | Relatively high |
| Custom Projects | Notes |
|---|---|
| Dimensions | Inner diameter: 20 mm-300 mm; height: 30 mm-500 mm (customizable to any specifications) |
| Wall Thickness Design | Optimize wall thickness (typically 8-25 mm) based on the type of metal and melting temperature |
| Capacity marking | Laser-engraved weight markings (e.g., "1 kg Au," "5 kg Ag") |
| Matching graphite cover | Flat lid or grooved lid available, designed to fit the crucible opening precisely |
| Special Treatment | Inner surface polished; outer surface coated with an anti-oxidation treatment |
