Customized tube furnace

Key points for selecting customized tube furnaces:

1. Customized core parameters: matching experimental requirements
temperature range
Clearly define the maximum temperature requirements (such as 1200 ℃, 1400 ℃, 1800 ℃) to avoid over customization or insufficient functionality. For example, the preparation of lithium battery materials requires around 1200 ℃, while ceramic sintering may require over 1600 ℃.
atmosphere control
Select the atmosphere type based on experimental requirements (such as inert gas, reducing gas, vacuum environment). For example, the research on fuel cell catalysts requires a H ₂/Ar mixed atmosphere, and the synthesis of semiconductor materials requires a high vacuum environment.
Furnace tube size and structure
Customize furnace tube diameter and length according to sample size (such as Φ 200mm × 1500mm), supporting large workpieces or batch processing. For example, metal powder processing requires large-diameter furnace tubes, while thin film materials require small-diameter high-precision furnace tubes.
Temperature zone and temperature control accuracy
Multi temperature zone design (such as three temperature zones) can achieve gradient temperature control and meet complex experimental requirements. It is recommended to choose a temperature control accuracy within ± 1 ℃ to ensure experimental reproducibility.
Special function extension
Select functions such as rotation, tilt, and rapid cooling according to experimental requirements. For example, the rotation function can improve the sintering uniformity of powder samples, and the tilting function can promote gas exchange.

2. Manufacturer selection criteria: dual guarantee of quality and service
Technical strength and industry experience
Priority should be given to manufacturers with ISO certification and over 10 years of industry experience to ensure equipment quality and after-sales service, and to support full process solutions from standard products to non-standard customization.
Customized cases and reputation
Referring to previous customized cases of manufacturers, priority should be given to manufacturers with experience in cooperation with universities and research institutes. For example, a certain university successfully synthesized graphene by customizing a three temperature zone vertical tube furnace, and a certain enterprise customized a 1400 ℃ horizontal tube furnace to increase the hardness of metal alloys by 20%.
Service response and after-sales support
Confirm whether the manufacturer provides 24-hour hotline, 48 hour on-site maintenance, lifelong technical support and other services.

3. Price and cost-effectiveness: long-term cost considerations
Initial procurement cost
The price is influenced by factors such as temperature range, atmosphere control, heating elements, etc.
Long term operating costs
Consider factors such as energy consumption, consumables (such as heating element replacement cycles), and maintenance costs. For example, equipment using advanced heating technology and insulation materials can reduce energy consumption by 20% -30%.

4. Industry application case reference
In the field of new energy materials
A certain battery company customized a vacuum atmosphere rotary tube furnace for the preparation of negative electrode materials (Si/C composite) for lithium-ion batteries, which increased the initial charge and discharge efficiency from 72% to 89%.
Semiconductor and Electronics Field
A certain chip manufacturer customized a high vacuum multi temperature zone tube furnace for GaN epitaxial growth, reducing the dislocation density of epitaxial layers to 5 × 10 ⁶ cm ⁻ ² and improving the luminous efficiency of LED devices by 30%.
Research and University Fields
A research institute has customized a three temperature zone rotating tube furnace for the synthesis of two-dimensional transition metal sulfides (2D TMDs), with a single-layer MoS ₂ yield increased from 15% to 68%.
