The precision machining we usually talk about generally refers to precision CNC Machining, CNC turning, CNC milling, CNC turning and milling composite machining, grinding, wire cutting, EDM machining, etc. The parts obtained by these machining methods can usually achieve relatively high precision and surface finish. Moreover, Precision Machining Parts has a wide selection of materials, and most materials can be used for CNC machining. Since the precision machining parts need to be machined one by one on the machine tool, the cost of mass production is relatively high compared with the parts that are directly formed by the mold. Of course, the most suitable and reasonable processing method to choose mainly depends on the product materials and the requirements of the product itself. SCZY has very rich experience in Precision Machining Parts and CNC Machining Parts ( They are included the stainless steel machining parts, aluminum machining parts, brass machining parts, titanium machining parts, plastic machining parts etc). Our normal machining accuracy can reach ±0.01mm, and for some special requirements, the accuracy can reach ±0.005mm (depending on specific products). We usually choose the most reasonable method according to the drawing requirements and recommend it to customers. Below are some pictures of precision machined parts for reference only.

Recently, following the start of the construction of 1.5 million tons of methanol and 1 million tons of dimethyl ether, which was jointly built by Shandong Jiuji Chemical Co., Ltd. and Shanxi Jincheng Orchid Group with a total investment of 4.5 billion yuan, China Shipping Chemical Co., Ltd Investment agreement for 580 million U.S. dollars annual output of 600,000 tons of synthetic ammonia and 1.04 million tons of urea, and an agreement reached between China Overseas Chemical and Orchid Group to invest 260 million U.S. dollars to build an annual output of 300,000 tons of synthetic ammonia and 520,000 tons of urea. The news involved 840 million U.S. dollars.
It is said that these are only small dishes on the Jincheng coal chemical feast. What the industry called a big dish was the total investment of 33.8 billion yuan signed by Orchid Group, Hong Kong Huaming Group Co., Ltd., Taiwan Foxconn Technology Group, and Indonesian Golden Paper (China) Investment Co., Ltd., to build an annual output of 600,000 tons of polypropylene, 1 million tons of dimethyl ether and 100,000 tons of polyformaldehyde are three major coal chemical projects.
In a few short years, with the signing of a number of heavy-duty coal chemical projects, projects, and start-up construction, huge social funds have been continuously invested in the Jincheng coal chemical industry. This phenomenon, the analysis of experts in the industry believes that this is primarily because the country has improved the access threshold for the coal chemical industry. Now a coal chemical project is frequently investing several billion yuan and tens of billions of yuan. One or two companies in Shanxi Province are difficult to achieve in terms of capital and technology, which provides foreign investors with an opportunity. Secondly, it is related to the transformation of Shanxi in recent years. Due to factors such as the environment, Shanxi began to develop into the field of deep processing of coal. Shanxi Province encourages domestic and foreign capital, including foreign capital, to invest in the coal chemical industry. Large coal companies in Shanxi are no longer simply digging coal to sell coal, but have entered the coal chemical industry. Deputy Governor of Shanxi Province Shan Shanzhong said: "The 11th Five-Year Plan of Shanxi has made greater efforts to adjust the economic structure. The province requires that the non-coal revenue of the five major coal groups exceed the main business of coal."
According to Xia Zhengui, mayor of Jincheng City, in addition to the investment environment, foreign capital is mainly used in the resource advantage here. Jincheng City is China's largest anthracite coal base and fertilizer raw coal base. More than 70% of the country's nitrogen-based fertilizer production companies rely on Jincheng anthracite. Investment in Jincheng is more profitable than elsewhere. Some experts said that if you invest in other areas of coal chemical industry to make money, Jincheng investment will surely make money; Even if the investment in other areas of coal chemical industry does not make money, then invest in Jincheng will make money. For example, nitrogen fertilizer, as coal generally accounts for 35% to 40% of the total cost, under the situation that higher coal prices lead to higher production costs, excess production capacity of nitrogen fertilizers, and falling sales prices, reducing costs becomes an inevitable factor for enterprises. If you choose to invest in the construction of urea plant in Jincheng, under the premise of the same level of management, equipment, and processes, because the cost of shipping is saved and the provincial fees are saved, the profit per ton is more than 300 yuan more than that in other regions.
According to expert analysis, Jincheng has several major advantages under the current situation where international oil prices are soaring and the cost of oil and natural gas as raw materials is significantly higher than that of coal. If there is sufficient electricity supply, the industrial electricity price is lower than most of the domestic provinces. Tonnage urea power consumption of domestic first-class managed enterprises is calculated as 300 kWh, the electricity consumption difference is 99 yuan/ton, and the total energy consumption difference between coal and electricity is 359. Yuan / ton. In addition, in the case of relative water shortage in North China, Jincheng is rich in water, and the average annual rainfall is about 700 milliliters. In some years, it reaches 1000 milliliters, and the rainfall in the south of the Yangtze River is about the same. Furthermore, according to the new “Road Traffic Lawâ€, the increase in automobile freight after limited load is up to 20% to 100%, and the relative lack of capacity will affect the operating rate and push up the cost of nitrogen fertilizer. The Jincheng chemical products are exported to the railway line after being produced in raw materials, which has the advantage of low-cost transportation.
Huge policy orientation, resource advantages and economic interests are attracting huge amounts of social funds to continue to invest in Jincheng coal chemical industry. The reporter asked the investor about the risk of investing in Jincheng. The investor said that in the fierce market competition, if the domestic coal chemical companies fall, Jincheng's enterprises should be the last batch. According to incomplete statistics, Jincheng’s enterprises and cities have participated in various types of trade fairs in the past four years and have signed hundreds of investment, technology, and trade contractual agreements. The total investment amounts to more than 100 billion yuan, and the amount of investment in the agreement exceeds 6 billion US dollars. It is expected that through hard work, Jincheng will become the world's largest high-concentration nitrogen fertilizer base using coal as raw materials and an important coal chemical base with methanol and dimethyl ether as the key nationwide. At the same time, it will provide huge business opportunities and profits for domestic and foreign consortia and enterprises. Space.
In recent years, Shanxi Jincheng's coal chemical industry has entered a frenzy of “great leap forward†era, and huge amounts of domestic and foreign capital are rushing to participate in the coal chemical industry here.
