Introduction: Precision Matters in Heating Element Production

As a core component of heating equipment, the filling of internal insulating materials—such as magnesium oxide powder—and the precision placement of positioning plugs directly determine a product's dielectric strength, thermal conductivity, and service life.

Traditional manual plug insertion methods often result in operational instability, efficiency bottlenecks, and risks of foreign material contamination. To address these challenges, our factory has implemented a fully automated solution.

Advanced Technology: Fully Automatic Plug Insertion Equipment

Our fully automatic plug insertion equipment integrates three key technologies:

• Vision positioning system for accurate alignment

• Servo pressing mechanism for consistent force application

• Online inspection module for real-time quality verification

Using high-precision robotic arms, the system automatically picks and places positioning plugs. Pressure and displacement sensors monitor the assembly process in real time, ensuring that the insulating medium inside each electric heating tube achieves optimal density and concentricity.

Key Benefits of Automation

1. Enhanced Efficiency

Automated production lines operate continuously and reliably. Single-machine productivity increases by over three times compared to manual operations, significantly shortening order delivery lead times.

2. Improved Quality Consistency

Digital closed-loop control eliminates subjective variations associated with manual work. The product yield rate exceeds 99.5%, with notably enhanced reliability in high-temperature and high-pressure applications.

3. Traceable Production Data

The system collects real-time data on cycle times, pressure curves, and critical parameters. This provides precise data support for quality management and process optimization.

4. Reduced Operational Intensity

By shifting personnel from repetitive manual labor to equipment maintenance and process management, the system improves the working environment and enables a more skilled talent structure within the factory.

Commitment to Quality & Innovation

"The automatic plug insertion equipment is not just a hardware upgrade; it represents the implementation of our commitment to 'Quality First.'"

"Driven by new quality productivity, we will continue to increase our investment in automation and digitalization, providing global customers with more stable and efficient electric heating element solutions."

Applications & Future Outlook

Our products are widely used across multiple industries:

• Household appliances

• Kitchen appliances

• Heating equipment

• Industrial heating equipment

Looking ahead, we plan to extend our automation expertise to other manufacturing processes—including tube forming, sealing, and annealing—with the goal of building a leading intelligent manufacturing base for electric heating tubes.
