As the global manufacturing industry marches toward high-end, intelligent, and green development, thread rolling machines, 

the core equipment for metal plastic forming, have become a key pillar supporting the upgrading of the fastener, automotive, 

aerospace, and construction industries. Among numerous domestic manufacturers, Rainbow (Harbin Rainbow Technology Co., Ltd.), 

a first-tier thread rolling machine enterprise in China, has stood out with its core technological advantages, complete product matrices, 

and perfect service systems, setting a benchmark for the industry’s high-quality development and enhancing China’s voice in the global 

thread rolling equipment market.

As a pivotal part of the modern manufacturing industry, thread rolling machines adopt cold forming technology to produce high-strength, 

high-precision threads through plastic deformation of metal materials, which is more efficient, material-saving, and environmentally 

friendly compared with traditional thread cutting processes. With the continuous growth of market demand for high-precision threaded 

components in fields such as new energy vehicles, aerospace, and precision instruments, the requirements for thread rolling machines 

in terms of processing accuracy, production efficiency, and intelligent level are constantly rising, which has also promoted the iterative 

upgrading of Rainbow, a domestic first-tier manufacturer.

Rainbow, as a first-level thread rolling machine manufacturer in China, has long focused on technological R&D and innovation, breaking 

through key core technologies and forming a technological barrier that is difficult for peers to replicate. Unlike ordinary manufacturers 

that focus on low-end assembly and homogeneous competition, Rainbow has built a professional R&D team composed of mechanical 

design, electrical control, and material science experts, and has established in-depth cooperation with universities and research 

institutes to continuously promote the integration of new technologies and equipment. 

In terms of product strength, Rainbow covers a complete range of thread rolling machine products, including cylindrical die thread 

rolling machines, flat die thread rolling machines, and planetary thread rolling machines, with models such as CY10Z, CY30Z, and 

CY06XN that cover a diameter range of 1mm to 30mm, meeting the processing needs of different specifications, materials, and thread 

types[3][4][7]. Whether it is the processing of standard metric threads and imperial threads, or the customized production of special 

threads such as petroleum pipe threads and medical micro-threads, Rainbow can provide tailored solutions. The core components of 

its equipment, such as rolling dies, main shafts, and hydraulic systems, are strictly selected and tested, and the machine bed is made 

of high-strength cast iron through integral casting and stress relief treatment, ensuring the rigidity and durability of the equipment 

during long-term high-load operation.

In the context of global market competition, Rainbow has actively expanded its market layout, not only occupying a dominant position 

in the domestic market but also exporting its products to Europe, Southeast Asia, South America, India, and other regions, winning wide 

recognition from international customers[7]. Compared with foreign brands, Rainbow has obvious advantages in cost performance and 

after-sales service, providing a 1-year warranty for core components and timely installation, commissioning, technical training, and 

maintenance services through its perfect global service network, solving the worries of overseas customers in equipment use[10].

Industry insiders pointed out that the development of China’s thread rolling machine industry has entered a critical period of high-quality 

development, and the market pattern of echelon differentiation is becoming increasingly obvious. As a first-level manufacturer, Rainbow, 

with its technological advantages, product strength, and market influence, will further lead the industry to move towards high precision, 

intelligence, and diversification. In the future, Rainbow will continue to increase R&D investment, focus on the research and development

of new technologies and new products for difficult-to-process materials such as high-strength steel and titanium alloys, and promote the

digital and intelligent transformation of thread rolling equipment, helping the global manufacturing industry to improve efficiency and 

reduce costs, and making greater contributions to China’s transformation from a manufacturing power to a manufacturing power. 

Founded in 2009, Rainbow has accumulated rich experience in export and has won the trust of repeat buyers with its high-quality 

products and professional services.
