1. Core advantages: precise control and efficient performance
Accurate temperature control
Adopting a PID temperature control system, combined with high-precision thermocouples (such as N-type and S-type) and solid-state relays, to achieve temperature control accuracy within ± 1 ℃. For example, in ceramic powder sintering, temperature fluctuations at 1600 ℃ need to be controlled within ± 5 ℃ to ensure material density and grain size uniformity.
Flexible atmosphere adjustment
Supports single or mixed atmospheres such as nitrogen, argon, hydrogen, oxygen, etc., equipped with mass flow meters (MFC) and oxygen content analyzers, which can monitor and adjust the oxygen concentration in the furnace in real time. For example, metal annealing requires nitrogen protection, while carbon material processing requires an argon environment to prevent oxidation.
High heating efficiency
Using resistance wire, silicon carbon rod, silicon molybdenum rod or graphite heating element, combined with ceramic fiber furnace, to achieve rapid heating and uniform heating (temperature uniformity ≤± 10 ℃). For example, hard alloy processing requires rapid heating to reduce oxidation, while high-temperature alloys require gradual heating to prevent thermal stress cracking.
Reliable safety performance
Equipped with multiple safety devices such as over temperature protection (such as independent temperature limiter), gas leakage alarm (such as gas sensor), explosion-proof design (such as furnace door water cooling, pressure relief valve), etc., to ensure stable operation of the equipment under extreme conditions.

2. Customization direction: meet diverse needs
Customized temperature range
Select the highest temperature based on material characteristics, such as ceramic sintering requiring 1200-1600 ℃, metal heat treatment requiring higher temperatures, and refractory metals (tungsten, molybdenum) requiring above 1600 ℃ for treatment.
Customization of furnace size
Select furnace volume based on sample size and batch size. Laboratory small furnaces (such as 100mm × 100mm × 100mm) are suitable for small sample sizes, while industrial large furnaces (such as 500mm × 500mm × 500mm) support batch processing.
Customized atmosphere type
Select the atmosphere type according to the process requirements, such as reducing atmosphere for metal powder reduction, inert atmosphere (argon) for carbon material treatment, and oxidizing atmosphere (oxygen) for metal oxidation experiments.
Customization of functional modules
Optional vacuum system (vacuum degree ≤ 10 ⁻ ³ Pa), rapid cooling device (such as air-cooled/water-cooled), data recording and analysis software, etc., can be equipped to enhance equipment functionality and experimental efficiency.

3. Key points for purchase: equal emphasis on quality and after-sales service
Brand and Supplier Selection
Limited selection of products from manufacturers with strict quality control and long-term market validation, low failure rates, and fast after-sales response.
Comparison of Technical Parameters
Temperature control accuracy: Laboratory grade equipment should be ≤ ± 1 ℃, while industrial grade equipment can be relaxed to ± 5 ℃.
Temperature uniformity: The temperature difference in the core area is ≤± 10 ℃ to ensure consistency in sample processing.
Heating speed: Select according to process requirements, such as rapid annealing requiring ≥ 10 ℃/min.
After sales service guarantee
Warranty period: Priority should be given to suppliers who provide a complete machine warranty of more than 1 year.
Technical support: Suppliers need to provide value-added services such as operation training and process optimization guidance to lower the threshold for use.Click to learn more Atmosphere Furnaces! Or click on online customer service to learn more about product information!
