How Dedou Manufactures High-Quality Electric Heating Tubes

In today’s fast-paced industrial world, the demand for reliable and efficient electric heating tubes continues to grow. These components play a crucial role in applications ranging from household appliances to industrial machinery. At Dedou, we believe that true quality comes from precision — and every heating element we produce is a reflection of that belief.

Our production process combines automation with craftsmanship to achieve consistency and reliability. Here’s how we bring each electric heating tube to life:

• Tube Cutting: Each metal tube is measured and cut with micron-level precision to guarantee perfect size and fit.
• Powder Filling: High-purity insulating powder is filled to stabilize the heating wire and ensure uniform heat distribution.
• Welding: Skilled technicians weld the resistance wire and cold ends to ensure excellent conductivity and long lifespan.
• Polishing: The tube surface is polished to remove imperfections and enhance both performance and appearance.
• Testing: Every heating element undergoes strict performance and safety inspections before delivery.

Each step matters — and together they define the quality that makes Dedou stand out.
