Stepping into Tongtuo Instruments' copper parts workshop, the rhythmic sound of precision forging machines mingles with the faint metallic scent. Factory Director Wang picks up a newly formed water meter copper casing and examines it carefully against the light: "When making copper parts, materials are fundamental. We insist on using high-grade leaded brass; for drinking water contact parts, safety and reliability are paramount."
Core Products: The Precision Forged "Iron Triangle"
1. One-piece molded copper casing
Formed in one piece using an 800-ton precision forging machine, resulting in a smooth and dense inner wall. General Manager Wang often says, "A good meter casing is 'forged'; only with uniform density can it withstand various water pressure impacts, ensuring the long-term stability of the metering chamber."
2. Reinforced Copper Connectors
Foreign Trade Manager Tang points to a batch of connectors about to be shipped to the Middle East, explaining, "Based on the local water quality characteristics, we thickened the pipe walls and optimized the thread design. Although the cost has increased slightly, the service life can be extended by more than 30%."
3. Precision Copper Nuts
In the packaging area, Office Director Zhu is inspecting the improved individual packaging. "Even small parts require high standards," she says. "We optimized the packaging lining to ensure that the threads of each nut are well protected during transportation."
Quality Assurance Through Diligent Responsibility
On Manager Tang's desk are pipe thread standard manuals from multiple countries. "Different markets have different needs," she says while organizing samples. "A few days ago, we also adjusted the chamfer angle of the connector heads for a European customer, just for easier installation."
Manager Zhu conducts two daily inspections of the workshop, focusing on temperature and humidity control in the raw material storage area. "Copper is susceptible to moisture, especially during the rainy season in the south. The storage environment directly affects the quality of subsequent processing," she said, pointing to the temperature and humidity record sheet on the wall.
Meticulous Craftsmanship, Steady Progress
As evening fell, the last batch of copper parts for the day completed surface treatment and were neatly stacked, awaiting the next process. During a workshop inspection, General Manager Wang told the quality inspectors, "Copper parts are the foundation of the water meter. With a solid foundation, the smart modules above can function fully. What we do may not be the most dazzling part, but it must be the most reliable."
As this batch of copper parts enters the assembly process, they will soon become an indispensable support for smart water meters. At Tongtuo, meticulous attention to basic components is always the most solid foundation of product quality.
