Disc Springs are conical annular discs that bear axial in and out, generally with constant disc thickness and uniform load distribution on the inner edge of the upper surface and the outer edge of the lower edge. Disc springs are usually made of spring steel and can withstand static loads, non-alternating loads, dynamic loads, and can meet strict fatigue life and loading loss requirements Compression Spring,Compression Disc Spring,Disc Spring Washer,Compression Spring Washers Ningbo FLK Technology Co., Ltd. , https://www.flk-global.com
China's auto industry is increasingly demanding machine tool consumption
The automotive industry's growth is deeply intertwined with the development of the machine tool industry, not just in terms of technological progress but also in the overall evolution of manufacturing capabilities. As a key "industrial machine," machine tools play a vital role in automobile production, representing roughly two-thirds of the fixed asset investment by automakers. This directly influences the cost of vehicle manufacturing, making the machine tool sector a critical driver of the auto industry.
The surge in demand for auto parts processing has become a major focus for machine tool consumption. According to industry analysis, nearly 40% of all machine tool usage comes from the automotive sector. This demand is primarily split into two categories: first, the four main lines used in complete vehicle production—stamping, welding, painting, and assembly—and second, the processing of individual auto parts such as engines, transmissions, braking systems, and suspension components.
While only the stamping line requires machine tools among the four main production lines, the bulk of machine tool consumption occurs at the second level—the processing of auto parts. This accounts for about 70% of the total equipment value in a vehicle. Some industry experts estimate that the demand for machine tools in auto parts manufacturing is more than ten times greater than that of original equipment manufacturers (OEMs).
At the heart of the automobile lies the engine, which relies heavily on specialized processing equipment. As car manufacturers accelerate the launch of new models, the flexibility of engine production lines has become increasingly important. A typical engine line must be capable of handling at least three different models. Additionally, the trend toward lighter vehicles has led to a shift from cast iron to aluminum alloys in engine blocks and cylinder heads, placing higher demands on machining technologies.
Key engine components include the cylinder block, cylinder head, crankshaft, camshaft, and connecting rod. Most of these require high-performance CNC or specialized machine tools. For example, horizontal machining centers are commonly used for cylinder and cylinder head processing, while crankshaft production involves truck-drawing machines, CNC internal/external milling machines, grinders, and polishing equipment. Camshaft processing typically uses CNC lathes and grinders, and connecting rod manufacturing often involves dedicated machines like double-face grinders.
As market competition intensifies, customers are placing stricter demands on automotive suppliers, focusing not only on product quality but also on technology, service, and safety. With national policies emphasizing energy efficiency and emission reduction, fuel economy and environmental impact have become central concerns. At the same time, rising labor costs in China are pushing auto parts manufacturers to adopt more advanced, efficient, and automated machine tools to address the growing challenge between manufacturing and labor expenses.
With the rapid expansion of vehicle production capacity, the need for increased auto parts output is inevitable. In response, manufacturers are turning to more sophisticated and automated solutions to maintain competitiveness and meet evolving industry standards.
