Zhejiang Shenlong Chain Drive Co., Ltd. – Technological Strength & Future Vision

The company attaches great importance to the automation upgrading of production processes, boasting a complete range of equipment, advanced technologies, and comprehensive testing facilities. It adopts advanced design tools including CAD, CAM, and SOLIDWORKS for 2D drafting and 3D modeling. Additionally, the company has established a well-equipped chain product R&D center and a chain testing center. It has successively obtained certifications such as ISO 9001-2008 (Note: The "ISO9001-2448" mentioned in the original text is likely a typo; the standard version is ISO 9001-2008/2015), ISO 9001-2015 Quality Management System, and EU CE Safety Certification, and has passed national quality supervision and testing on multiple occasions.

Continuous Innovation in Technology R&D

Adhering to the principles of high starting point, high standards, and strict requirements, the company continuously invests substantial funds in technological transformation and new product development. It focuses on the research and development of various special-shaped chains, constantly breaking the boundaries of traditional chain design and manufacturing. Starting from the initial Series A and B standard roller chains, the company has gradually expanded its product portfolio to include conveyor chains, motorcycle chains, speed multiplier chains, hollow pin chains, agricultural machinery chains, pointed-tooth chains, plate chains, toothed chains, continuously variable transmission (CVT) chains, overhead chains, stainless steel chains, and special-purpose chains. This diverse product range meets the rigorous demands of different industries and working conditions. Meanwhile, the company can also customize special-shaped chains according to customers’ personalized needs, fully demonstrating its strong technical customization capabilities.

Outstanding Patent Achievements

In the journey of R&D and innovation, Zhejiang Shenlong Chain Drive has reaped fruitful results. According to data from the National Intellectual Property Administration, the company has obtained a number of patent achievements:

• Patent for "A Double-Row Free Roller Chain for Logistics Conveyance": Compared with belt transmission, this double-row chain for logistics conveyance eliminates elastic sliding, ensuring accurate average transmission ratio, high transmission efficiency, low load on shafts and bearings, reliable transmission, and strong overload capacity. It can operate stably under low-speed and heavy-load conditions and is available in various types to meet the needs of different working scenarios. Additionally, it enables precise volume measurement via cameras, improving logistics efficiency and accuracy.

• Patent for "A Push-Pull Roller Chain for Conveying Devices": The designed push-pull roller chain (composed of first and second chain bodies) is suitable for harsh environments. The balls on the chain plates, combined with internal sleeves, ensure flexible chain operation and high speed. The push-pull integrated operation mode achieves labor-saving and high-efficiency performance, while ensuring long chain service life. By replacing rollers and adjusting eccentric distances, work efficiency is further improved.

These patent achievements not only serve as strong evidence of the company’s R&D capabilities but also help its products gain significant advantages in market competition.

R&D for Wide Industry Applications

With its strong R&D capabilities, the company’s products are widely used in mechanical transmission and conveying equipment fields such as home appliances, electronics, food processing, coating engineering, shoemaking, pharmaceuticals, mining, chemicals, tobacco, and light industry. The company deeply understands the process flows and technical needs of various industries, conducts targeted product R&D and optimization, and provides professional services for the localization of chains used in imported conveying equipment. This helps domestic industries improve equipment performance and production efficiency. Whether for complex industrial production lines or sophisticated electronic manufacturing equipment, Zhejiang Shenlong Chain Drive’s products can be accurately adapted and operate stably, providing reliable power transmission support for the development of various industries.

In future development, Zhejiang Shenlong Chain Drive will continue to increase R&D investment, continuously enhance technological innovation capabilities, and contribute to the development of the global chain drive industry with higher-quality products and more advanced technologies, while working hand in hand with customers to create a better future.
