China Drying Network News Air Products announced on July 18 that it has obtained an important contract from Samsung Electronics Co., Ltd. to supply ultra-high purity nitrogen and other bulk gases for Samsung Electronics' chip factory in Xi'an High-tech Zone, including oxygen and argon. Gas, hydrogen, helium, and compressed dry air . The first phase of the Samsung Electronics Project is scheduled to be put into operation in the second half of 2013. The project is Samsung Electronics’ largest foreign investment project to date and the most advanced chip factory in China. According to the contract, Air Products will invest in the construction of a number of large air separation plants. While providing gas to Samsung Electronics, liquid gas products will also serve the commercial gas market in the region.
Power spinning is also called thinning spinning. Power spinning is a non-cutting processing method developed on the basis of ordinary spinning. When spinning, use the tail top to fix the blank on the mold. When the mold rotates, the rotating wheel makes a feeding motion, so that the blank continuously becomes thinner point by point and abuts against the mold to form a part of the required shape. Power spinning realizes the forming of the workpiece by changing the thickness and shape of the blank.
On airplanes, various nose covers, auxiliary fuel tanks, air intakes, gas cylinders, tie rods, slide rails, and actuators are all formed by spinning. In the engine, most of the propeller cap, casing, lip, intake cone, nozzle, nozzle, etc. are also formed by spinning. Such parts have complex structures, special raw materials, and large product sizes. The use of spinning forming can improve the integrity of structural components, reduce welds and component deformation, and reduce the workload of manual calibration. More importantly, due to the increased strength of the material after spinning, the design wall thickness of the parts can be reduced, thereby reducing the weight of the whole machine and improving the reliability of the whole machine.
