For any tempering furnace, the control cabinet is the heart of the electrical system. Its assembly quality directly impacts the stability, safety, and lifespan of the entire machine. Achieving 100% correctness for every single connection isn't just a company goal—it's a commitment to professional excellence.

To meet this standard, we've implemented a series of strategic optimisations:

A Systematic Approach to Quality Control

Our process is built on a "triple-check" principle to eliminate errors from the start. We ensure that our installation diagrams, schematics, and wiring diagrams are all perfectly consistent. We also use different colored wires for different voltage levels to prevent confusion and errors. For complex wiring junctions, we perform simulated pre-wiring to identify and resolve any issues before final assembly.

To maintain order, we've adopted an advanced cable management system. This prevents tangled wires and signal interference, boosting both accuracy and efficiency. For critical connection points, we've introduced special tagging and logging procedures to ensure every step is traceable and verifiable.

Precision Tools for Flawless Execution

Our assembly technicians are equipped with high-precision tools to guarantee perfection. These include torque-adjustable screwdrivers (with a range of 0.2 to 10 N·m) to ensure every fastener is tightened to the optimal specification, preventing damage from overtightening or safety risks from loose connections.

We also use professional-grade stripping and crimping tools with an accuracy of ±0.2 mm. This ensures solid, reliable connections and reduces the risk of poor conductivity. Finally, a wire-numbering printer provides instant labelling, making every cable easy to identify for future maintenance and troubleshooting. Using these tools not only boosts the precision of our work but also significantly shortens the assembly time.

Comprehensive Inspection and Testing

Once the wiring is complete, we perform a multi-stage inspection process. Each operator conducts a 100% self-inspection, immediately followed by a cross-check of critical connections by a technician from an adjacent workstation. Any discovered defects are logged, and corrective and preventative actions are put into place.

Before any glass tempering machine leaves the factory, a specialised quality assurance team performs a comprehensive power-on test. Using simulated operating programs, they verify that the control cabinet functions reliably under real-world conditions. This rigorous testing focuses on key performance metrics, including the reliability of electrical connections, the accuracy of control logic, and the effectiveness of safety features. This final inspection ensures that we deliver high-quality, reliable control cabinets that meet and exceed our customers' needs.

Achieving 100% wiring correctness is not an unattainable goal. It requires a combination of systematic quality management, a culture of craftsmanship, and the use of modern technology. By controlling for errors at every step, from design to delivery, we transform each control cabinet from a simple collection of components into a true industrial masterpiece.
