Why China should vigorously develop high-end advanced tools? China now has the world's first automotive industry. However, the high-efficiency production lines introduced by the automotive industry from abroad have used 80% to 90% of the cutting tools that are still imported cutters (including domestically produced foreign-funded enterprises). Now China's tool production supply and marketing situation is that high-end advanced tool products mainly rely on imports, while the low-end tool products malignant expansion (most of the exports), this situation must be changed as soon as possible.

A large number of standard tools are used in China's machinery manufacturing industry, while developed countries use a large number of highly efficient cutting tools. This results in a much lower processing efficiency in China than in developed countries. China's tool factory still produces a large number of traditional standard tools, and some small tool factories also produce a large number of low-grade tools.

According to statistics, China consumes 40% of the world's tool materials, but its sales revenue only accounts for 12%-15% of the world's tool industry. The gross profit margin of the tool companies in developed countries is about 40%, while the profit of China's tool factory is very low, and some of the tool factories are still losing money.

Judging from the technological development trend of the machinery manufacturing industry, the proportion of high-efficiency CNC machine tools in China's factories will increase year by year, and the demand for efficient and advanced tools will increase rapidly, while the demand for traditional standard tools will decrease year by year. In addition, due to the increase in labor costs in China, the price advantage of the middle and low-end standard tool exports will gradually be lost, and the export volume will surely decrease.

For example, if tool companies still produce traditional standard tools, the sales volume will gradually shrink. It is worrying that some private small-scale tool manufacturers produce traditional standard tools in large quantities. Large-tool factory gradually loses the market due to high costs and no competition. ).

Therefore, China's tool industry must change its concepts, vigorously develop the production of high-efficiency cutting tools, attach importance to after-sales production services, use domestically-made high-efficiency cutting tools to replace foreign products, and recapture this portion of the market occupied by imported tools. Only in this way will our country's tool companies have a future for development, and the country’s tool industry can be rejuvenated.

Valve Part

Valve part is kind of pipeline fittings, which is used to open and close, control, adjust and control the flow of medium parameters (temperature, pressure and flow). According to its function, it can be divided into the cut-off valve, check valve, regulating valve, etc.
Valve is the control unit in fluid conveying system, having function of cut-off, regulation, guide, to prevent the reverse flow, voltage regulator, the leakage of the shunt or overflow and so on. Valve parts used in fluid flow control system, have quite a wide varieties and specifications, from the most simple cut-off valve to all kinds of valves used in extremely complex automatic control system.
The valve can be used to control air, water, steam, all kinds of corrosive medium, mud, oil, liquid metal and radioactive medium. According to the material, valve part is divided into iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome molybdenum steel valves, molybdenum chrome vanadium steel valve, dual phase steel valves, plastic valves, non-standard custom-made valves, etc.
