A Vacuum Molybdenum Foil Furnace was Sent to Pakistan
A 1300°C vacuum molybdenum foil furnace was recently shipped to a materials manufacturer in Pakistan. This article provides a detailed overview of the case.
Customer Background
The customer is headquartered in Karachi, Pakistan, and is a leading materials research and manufacturing enterprise established in 2010. They specialize in providing high-performance materials for the aerospace, electronics, and energy industries. In recent years, they have been committed to developing ultra-thin molybdenum foil components for next-generation semiconductor devices. They require a specialized furnace capable of achieving extreme high temperatures (1300°C) in a vacuum environment.
With the rapid growth of Pakistan's technology industry, the customer evaluated multiple suppliers from Europe, China, and the United States. Ultimately, they chose to partner with us to customize a vacuum molybdenum foil furnace that meets their stringent requirements.
Why Choose a Molybdenum Foil Chamber?
Molybdenum is an ideal material for high-temperature vacuum furnace chambers due to its unique physical and chemical properties:
High-Temperature Resistance:
With a melting point of 2620°C, molybdenum maintains excellent mechanical strength and creep resistance at 1300°C, ensuring long-term stable operation of the furnace chamber.
Low Thermal Expansion Coefficient:
Molybdenum’s thermal expansion coefficient is close to that of silicon and other semiconductor materials, reducing the risk of deformation at high temperatures and ensuring dimensional accuracy in molybdenum foil heat treatment.
High Purity and Anti-Contamination:
Molybdenum exhibits minimal volatilization in vacuum environments, preventing contamination of sensitive materials—particularly crucial for AMS’s research on semiconductor-grade molybdenum foils.
Uniform Thermal Field Distribution:
The high thermal conductivity of molybdenum, combined with a customized radiation shield design, ensures temperature uniformity (±1°C) within the furnace chamber, meeting the stringent requirements for homogeneous processing of ultra-thin foils.
Compared to traditional stainless steel or graphite furnace chambers, molybdenum foil chambers offer superior high-temperature stability, material compatibility, and process consistency, making them a key enabler for technological advancements.
Shipping and Packing
The transportation of high-precision equipment from China to Pakistan required meticulous planning:
Pre-shipment Testing:
A 72-hour continuous trial run was conducted to verify temperature stability and vacuum performance.
Customized Packaging:
The equipment was disassembled into shockproof containers with built-in moisture-control desiccants.
Vacuum pumps and other precision components were packed separately to prevent damage from transportation vibrations.
Logistics Coordination:
An experienced freight forwarding company was selected.
Air freight was chosen to shorten the delivery cycle and mitigate the risk of corrosion from sea transport.
The furnace successfully arrived in Karachi within 10 days.
Conclusion
The successful delivery of the 1300°C vacuum molybdenum foil furnace marks a win-win collaboration between the Pakistani customer and our company.
This case highlights the value of cross-border cooperation in the field of materials science. As Pakistan continues its industrial advancement, we look forward to exploring further opportunities for collaboration, driven by innovation and reliable service.
