Molybdenum crucibles of non-standard sizes can be customized, and customization is a common demand in the molybdenum crucible industry. The following is a detailed description:
- Feasibility of Customizing Non-standard Sizes
Material properties support
Molybdenum (Mo) has a high melting point (2623°C), high strength and good high temperature stability, and can be processed into complex shapes through forging, spinning, welding and other processes. Powder metallurgy technology can achieve near-net shape and reduce the amount of subsequent machining.
- Key parameters for customizing non-standard sizes
| Parameter | Range/Description |
|–||
| Diameter | 20-500 mm (laboratory grade) to more than 500 mm (industrial grade) |
| Height | 50-1000 mm, special structures such as stepped and conical shapes can be customized |
| Wall thickness | 1-10 mm, adjusted according to diameter and purpose (e.g. crystal growth requires ≥5 mm, and can be as thin as 1 mm for laboratory use) |
| Tolerance | Diameter ±0.1 mm (precision grade) to ±1 mm (industrial grade) |
| Surface roughness | Ra0.2 μm (optical grade) to Ra1.6 μm (industrial grade) |
| Special structure | Bottom boss, side wall opening, flange interface, etc., 3D drawings or technical requirements are required |
- Customization process and precautions
Demand confirmation
Provide dimension drawings, application scenarios (such as crystal growth, metal smelting), temperature range, vacuum requirements, etc.
Specify details such as tolerances, surface treatment (such as polishing, pickling), etc.
Technology Assessment
The supplier evaluates the processing feasibility, such as ultra-thin walls (≤1 mm) require special molds and welding processes.
Provide quality certifications such as material reports (such as purity ≥ 99.95%) and non-destructive testing (such as X-ray flaw detection).
Cost and cycle
Cost: Non-standard sizes are usually 20%-50% more expensive than standard sizes, and complex structures may cost double that.
Turnaround time: 4-8 weeks (domestic) to 12-16 weeks (international), depending on the difficulty of the process.
