Hubei Wuhan Economic Development Zone has developed from a wasteland hillock into a modern manufacturing highland development zone in central China. The pace has grown steadily, and the output value growth rate has remained at around 50% for several years. The person in charge of the Management Committee of the Development Zone stated that the development zone conscientiously implements the scientific concept of development, relies on many well-known corporate brands, promotes the development of industrial clusters, and achieves high quality investment promotion. Being built by car is a unique feature of the Wuhan Economic Development Zone. The development of a 300,000-sedle sedan joint venture between China and France 15 years ago gave birth to a development zone. Since its completion, it has become a major automobile and parts industrial base in the Midwest, tying up the two major automobile clusters of “Dragon†and “Dongfeng†and bringing together PSA, Nissan, and Honda. In the adjustment and change of previous industrial policies in the development zone, the main line of cluster development of the automobile industry has been clear.
In June last year, after Dongfeng’s two major headquarters were stationed in succession, Dongfeng Co., Ltd.’s headquarters officially moved to the development zone. Following this, Shenlong’s “Second Plant†investment project was also settled. Recently, the development zone also won the national award and became a One of the six “auto and auto parts export bases†in the country. At present, it has become China's most important automobile and auto parts production base, national electric vehicle R&D, demonstration operation, and achievement industrialization base. By the end of the “Eleventh Five-Year Plan†period, the development zone will have an annual production capacity of 800,000 vehicles, becoming a truly “automobile cityâ€.
The strong growth of vehicle companies has led to the demand for auto parts and automotive logistics. Wuhan Economic Development Zone has set a low threshold for these industries, and a large number of well-known auto parts and logistics companies such as Cummins, Quanxing, and Aiji have heard about it. As a result, a large number of automotive industry chains from R&D to sales are formed.
The shift from a single industrial cluster to an industrial integrated cluster is the only way to build a first-class industrial park brand.
The powerful “herd-effect†generated by the booming development of the automobile and parts industry in the Wuhan Economic Development Zone constitutes a huge attraction for other industries. Wuhan Economic Development Zone has formulated guidelines: vigorously introduce "leading" projects to build several industrial bases. They use leading enterprises to gather upstream and downstream companies, from large projects to industrial chains, and then to industrial clusters. The introduction of investment in development zones has always revolved around large and dominant enterprises. The clustering of industries and the degree of correlation between industries have been continuously enhanced. Many industries From scratch, from there to further grow. Among them, well-known computer shows that TPV and Proview have successively settled in the development zone.
Nowadays, the development zone gradually gathers into five dominant industrial clusters: the food and beverage industry represented by Coca Cola, Dingyi, and Dingjin, and the paper-making printing and packaging industry represented by Chenming Paper, Nanyang Printing, Huidian Packaging, etc. The electrical machinery and equipment industries represented by Haier, Midea, and McQuay are represented by the biomedical industry represented by Tung Shing Pharmaceuticals, Hite Biology and Tongji Modern Medicine.
What is the advantage of Wuhan Economic Development Zone? The person in charge of the Development Zone Management Committee believes that many first-rate enterprises are concentrated in the development zone and attract multinational companies' R&D centers so that Chinese and foreign enterprises can fully realize technological exchanges and resource sharing. This has saved the development zone a strong potential for sustainable development. The strength of independent innovation continues to grow through the power of clusters.
In the 15 years since the establishment of the zone, the total investment in the zone has been more than 7 billion yuan, and ten ports and one level have been achieved within a range of 40 square kilometers. The functional departments of the Development Zone have continuously enhanced their service awareness and gradually established a management system and operating mechanism that are compatible with the requirements of internationalization and marketization. In the comprehensive evaluation of the investment environment of the 54 national-level economic and technological development zones announced by the Ministry of Commerce in 2006, the Wuhan Development Zone ranked first in the Central and Western Development Zone.
The Introduction of PCD
The PCD (Polycrystalline diamond) is a composite material, consisting of sintered diamond particles with a metallic binder. Diamond is the hardest material in absolute terms and therefore also the most resistant to abrasion. Used as a cutting tool, it has a good wear resistance, and a yield superior to traditional sharp carbide. The machined surface roughness with the PCD can reach comparable to the adjustment.
Main applications
â–²Processing of non-ferrous
â–²Aluminum alloys with high or low silicon content (pistons, engine blocks engine, wheels, carburetors, connecting rods, gear boxes, cylinders for brakes, etc.).
â–²Bronze and copper alloys (copper manifolds, engine bearings, bushings, connecting rods eyes, locations pumps etc.).
â–²Tungsten carbide (trafilatori rollers and other components sintered etc).
â–²Pieces composed of aluminum and lead, aluminum engine blocks with cast iron pipes reported
â–²Processing of non-metallic materials
â–²Very abrasive materials, such as ceramics industrial uncooked.
â–²Some fired ceramic: zirconia aluminum oxide, such as spark plugs and insulators.
â–²Glass, plastics with glass fibers, carbon fibers.
The Introduction of PCBN
PCBN has the characteristics of high thermal stability, high hardness, high wear resistance and. It`s inert to iron family element, hence PCBN is mainly used for the machining of high hardness and hard processed ferrous materials, such as d facing alloys, harden steel, pearlitic gray cast iron, high temperature alloy, high-speed steel, hard facing alloys, Ni-Cr alloy, powder metallurgy metals.
