How to choose a tube furnace manufacturer?

When choosing a tube furnace manufacturer, it is necessary to comprehensively evaluate five core dimensions: technical strength, product customization ability, quality control, service response, price and cost-effectiveness. Let’s take a detailed look at how to choose a tube furnace manufacturer below!

1. Technical Strength: Core Components and R&D Capability
Heating element technology
Priority should be given to manufacturers who use high-performance heating elements such as silicon carbon rods and silicon molybdenum rods. These elements are resistant to high temperatures, have a long lifespan, and are suitable for high-temperature sintering or corrosive environments.
Accuracy of temperature control system
High precision temperature control systems, such as PID regulation and multi-stage program control, are key to experimental repeatability. The touch screen high-temperature tube furnace of Zhengzhou Kejia Electric Furnace Co., Ltd. achieves a complex heating curve through intelligent programming, with temperature fluctuations of ≤± 1 ℃, suitable for scientific research applications.
Industry technology accumulation
Priority should be given to manufacturers with over 10 years of industry experience, who can provide full process solutions from standard products to non-standard customization.

2. Product customization capability: matching experimental needs
Customization of pipe diameter and size
Select the pipe diameter based on the sample size (such as processing block materials with large pipe diameters and rotating heating with variable diameter pipes), provide multiple pipe diameter options, and support customized design.
Temperature zone and atmosphere control
Multi temperature zone tube furnace (such as three temperature zone slide tube furnace) can achieve independent temperature control in different areas, suitable for gradient sintering experiments; Vacuum or atmosphere control functions (such as inert gases, reducing gases) are essential for chemical synthesis and metal heat treatment.
Special function extension
The tilting and rotating function (such as the high-temperature atmosphere rotating tube furnace of Henan Zhonghuang Furnace Industry) and rapid annealing (RTP technology) can improve experimental efficiency.

3. Quality Control: Material and Process Standards
Furnace material
High quality furnaces (such as alumina polycrystalline fibers) have high temperature resistance and good insulation effect, which can reduce energy consumption. Using high-density furnace materials, the heating uniformity is ≤± 3% to ensure experimental consistency.
Security protection design
It must have functions such as over temperature alarm, leakage protection, emergency stop, etc. Its safety performance meets international standards and reduces the risk of use.
Raw material procurement standards
Priority should be given to manufacturers using raw materials from reputable brands to ensure a product lifespan of over 5 years.

4. Service response: Pre sales and after-sales support
Pre sales technical consultation
A good tubular furnace manufacturer provides one-on-one consultation and recommends suitable models based on experimental objectives to avoid cost waste caused by “selection errors”.
Installation, debugging, and training
On site guidance for installation and debugging is crucial for the stable operation of equipment. Zhengzhou Kejia Electric Furnace provides professional engineers for on-site service and trains operators to reduce initial running in problems.
After sales service network
24-hour hotline, 48 hour on-site maintenance, and lifelong technical support are basic requirements to quickly respond to customer needs.

5. 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
Energy consumption, consumables (such as heating element replacement cycles), and maintenance costs need to be included in the evaluation.
Brand reputation and case reference
Priority should be given to manufacturers with cooperation cases between universities and research institutes.
