Our Strengths-Changzhou Jinao Roller Machinery Co., Ltd.

Vertical Integration & Strict Quality Control

Jinao owns both a machining factory and an electroplating plant, enabling independent processing and greater cost control for our clients. With our in-house machining workshop and electroplating facility, we have achieved vertically integrated production from raw materials to finished products. This independent supply chain allows us to exercise tighter control over every production stage—ensuring consistent product quality while effectively optimizing manufacturing costs, ultimately delivering cost-effective solutions that maximize your value.
Consistent Record of Innovation

Our robust R&D and engineering team serves as a solid backbone for your innovation projects. Whether you provide detailed drawings, technical specifications, or a physical sample, we can conduct in-depth analysis, reverse engineering, and custom development, accurately transforming your concepts into high-performance, reality-ready products.
Full-Size Range & Comprehensive Surface Treatment

We are capable of manufacturing rollers of virtually any size and specification, from small precision rollers to large-scale industrial rollers. Furthermore, we offer a comprehensive range of surface treatment services to meet diverse application requirements, including but not limited to rubber covering (various hardness levels and materials), ultra-hard and wear-resistant tungsten carbide coating, and anti-adhesive, chemical-resistant Teflon (PTFE) coating.

Serving Global Markets with Uncompromising Quality

We are committed to serving international markets, and we never compromise on quality. To uphold this commitment, we have invested in industry-leading precision inspection equipment, including profilometers, surface roughness testers, hardness testers, and more. Every roller we produce undergoes rigorous testing for dimensional accuracy, surface finish, dynamic balance, and hardness. This ensures that all our products meet or exceed international standards such as ISO and ASTM, and perform reliably in even the most demanding operating environments.
