Small items, great achievements

China's first high-speed maglev railway with complete independent intellectual property rights, the world's first shield machine driven by permanent magnet motor, and the Lishengyang Bridge - which set five "world records" - are just a few examples of these "major engineering projects" and "industrial giants". As a company specializing in precision components, Hunan Shenyi Precision Components Co., Ltd. supplies fasteners - commonly known as "screws" - to these "major engineering projects" and "industrial giants". 
In Hunan, enterprises in the construction machinery cluster have developed and produced a series of the world's "largest" and "heaviest" construction machinery, with a particularly prominent demand for the scenario-based and precision-oriented requirements of fasteners. "We have focused on meeting customer needs to drive our development. With the breakthroughs at the forefront of China's construction machinery equipment and technology, the research and development of fasteners has also entered an uncharted territory. We have thus grown into a 'small giant' enterprise," said Wang Kaibo, the head of Shenyi Precision. Through continuous efforts, Shenyi Precision has helped key construction machinery enterprises in Hunan achieve the domestic substitution of various fasteners.

In the manufacturing industry, fasteners are widely used and seem insignificant yet indispensable. Wang Kaibo said, "Through cooperation and independent research and development, Shenyi Precision has added customers from the automotive and road and bridge industries to its supply list. For instance, the weather-resistant steel rivets developed in collaboration with steel enterprises have achieved breakthroughs in high corrosion resistance, high precision, high strength, and high toughness, and have been successfully applied in the Lion Ocean Bridge project." 
The tiny "screw" can tightly connect the key components of construction machinery. One engine can ignite the "power engine" of low-altitude economy. The advancement of machine vision technology has expanded the application scenarios of industrial robots. The increasingly refined components are not only the result of technological innovation and upgrading, but also a vivid illustration of the advanced manufacturing industry moving towards high-end and intelligence.
