FAQ
What processes are high-temperature muffle furnaces suitable for?
Suitable for high-temperature sintering, annealing, and heat treatment in ceramics, metals, electronic materials, glass, and scientific research.
What’s the difference between 1700°C and 1800°C muffle furnaces?
The 1800°C model can operate at higher temperatures for extended periods, making it suitable for materials that require higher temperatures; the 1700°C model is ideal for standard high-temperature sintering and heat treatment.
Do they support vacuum or controlled atmosphere functions?
This series is designed for standard air environments and does not support vacuum or controlled-atmosphere systems; it is suitable for sintering and heat treatment in air.
What is the delivery time?
Standard models ship in 7–15 days, customized models in about 30 days, depending on order size and specifications.
