Certifications and Compliance

Our manufacturing facilities are ISO 9001 certified, ensuring that every furnace and hot zone component is produced to the highest standards of quality and consistency. All materials are sourced from reputable, conflict-free suppliers, reflecting our commitment to ethical practices that begins with partners **For Mining Tungsten**.

Customization Options

Customization is at the core of our offering. We can tailor:

• Furnace Size: From small R&D units to large-scale production furnaces.
• Hot Zone Design: We can design **Hot Zone Of Sapphire Growth Fixtures** for various growth methods (e.g., Kyropoulos, EFG, HEM).
• Crucible Material: Choose between pure tungsten, pure molybdenum, or specific alloys based on your process.
• Control Systems: We can integrate our furnaces with your existing factory management software.

Production Process

Our process begins with a detailed engineering consultation. Once the design is finalized, we begin fabricating the furnace body and control systems. In parallel, our specialized refractory metals division manufactures the hot zone components. This involves processes like powder metallurgy, high-temperature sintering, and precision machining of the tungsten and **Molybdenum Fabricated** parts. The hot zone is then assembled and installed into the furnace, followed by a complete system test before shipment.

FAQ

1. What is the typical lead time for a custom furnace?

Lead time varies depending on the complexity and size of the furnace, but typically ranges from 4 to 6 months from design finalization to delivery.

2. Can you supply replacement hot zones for our existing furnaces from other manufacturers?

Yes, a significant part of our business is providing custom-designed, high-performance replacement **Hot Zone Of Sapphire Growth Fixtures** that can be retrofitted into existing furnace systems to improve their performance and lifespan.

3. Why are tungsten and molybdenum used in the hot zone?

Tungsten and molybdenum have extremely high melting points (3422°C and 2623°C, respectively) and maintain their strength at the high temperatures required for sapphire growth (~2050°C). Their high purity also prevents contamination of the sapphire crystal.
