Technological Leadership—Jiangyin Carridea’s Advantage in Cold-Drawn Tube Processing Technology

In the cold-drawn tube industry, processing technology is the core competitiveness that determines an enterprise’s market position. Only those enterprises with cutting-edge processing technology and continuous innovation capabilities can produce high-quality, high-precision cold-drawn tubes that meet the diverse needs of industrial manufacturing. Jiangyin Carridea Technology Co., Ltd., adhering to the concept of “technology-driven development”, has continuously invested in technological research and development, optimized processing processes, and formed distinctive and obvious technological advantages, firmly leading the technological progress and high-quality development of the global cold-drawn tube industry.

Carridea has spared no effort in upgrading processing equipment, introducing a complete set of advanced, intelligent and high-precision processing equipment from home and abroad, covering the entire production chain of cold-drawn tubes—including fully automatic hydraulic cold-drawing units, boring-rolling integrated units, high-precision polishing machines, intelligent heat treatment equipment, and numerically controlled cutting equipment. These devices are not only equipped with advanced automation and intelligent control systems, which greatly reduce manual intervention and human errors, but also have outstanding advantages in processing precision and production efficiency, laying a solid foundation for the stability and consistency of product quality.

For instance, the hydraulic cold-drawing unit adopted by the company is equipped with an independently developed intelligent control system, which can accurately monitor and adjust key processing parameters such as drawing speed, drawing force and processing temperature in real time, with an adjustment accuracy of up to ±0.1mm, ensuring that the size, shape and mechanical properties of each cold-drawn tube fully meet the design requirements and industry standards. The boring-rolling integrated unit realizes one-step processing of the inner hole of the tube, which not only significantly improves the surface finish and dimensional accuracy of the inner hole (the surface finish can reach Ra0.4μm), but also reduces the number of processing steps by 30%, greatly improving production efficiency and reducing production costs.

Beyond advanced equipment, Carridea also boasts profound accumulation in processing technology. The company’s core technical team is composed of senior engineers with more than 18 years of experience in the cold-drawn tube industry, who have long been engaged in the research and development, optimization and innovation of cold-drawn tube processing technology, accumulating rich practical experience in solving complex technical problems. The company has continuously optimized the cold-drawing process, adopting a new type of wear-resistant drawing die and environmentally friendly, high-efficiency drawing lubricant, which not only effectively improves the surface smoothness and wear resistance of products, but also reduces lubricant consumption by 25% and prolongs the service life of the die by 40%.

In terms of heat treatment technology, Carridea has optimized the traditional quenching and tempering process, adopting a scientific and precise segmented heat treatment process, which effectively improves the strength, toughness and corrosion resistance of the tubes, making the products more adaptable to heavy-load, high-pressure and harsh working environments such as machinery manufacturing, petroleum and chemical industry.

Carridea has also made important breakthroughs in solving common technical bottlenecks in the industry, filling the gap in related fields. For example, aiming at the problem of uneven surface roughness of cold-drawn tubes that plagues the industry, the company has developed a composite polishing and finishing technology, ensuring that the surface roughness of all products is stably controlled within Ra0.8-1.6μm. For the problem of poor straightness of long-length cold-drawn tubes, the company has developed a precision straightening technology, controlling the straightness within 0.2-0.25mm/m, which is far higher than the industry average standard of 0.5mm/m. These technological breakthroughs not only enhance the competitiveness of the company’s products, but also promote the overall technological progress of the cold-drawn tube industry.

To maintain its technological leadership, Carridea continues to increase investment in R&D, establishing a professional R&D team and strengthening in-depth cooperation with well-known universities and research institutions to carry out joint research on key technologies. Up to now, the company has obtained more than 20 patents for invention and utility models, fully reflecting its strong technological innovation capabilities. At the same time, the company pays close attention to the development trend of advanced technologies at home and abroad, actively tracks and learns cutting-edge processing technologies, and continuously introduces, absorbs and innovates to continuously improve its own technological level.

With its advanced processing technology, high-precision equipment and strong technological innovation capabilities, Carridea has become a well-recognized leader in the cold-drawn tube industry. Its products have won wide recognition and a good reputation in the market for their high quality, high precision and high stability, and have been exported to Europe, Asia, Africa and other countries and regions. In the future, Carridea will continue to adhere to the path of technological innovation, further upgrade processing technology, optimize product structure, and provide more high-quality, high-performance cold-drawn tube products for the global industrial manufacturing industry, contributing to the development of the industry.
