Dingxiang Liantai Flange Co., Ltd.-Workers forging flange production technology-Our workers will select the appropriate billet material according to the flange size specifications, and use cutting equipment (such as sawing machines) to cut the billet into roughly appropriate sizes. The billet is placed in a heating furnace and heated to the appropriate forging temperature range, which varies depending on the type of steel, usually around 1000 - 1200℃.-Workers casting flange production technology-Workers first make the mold for casting. For sand casting, a sand mold is made, including an upper and lower sand box, in which the flange cavity is made; if it is metal mold casting, the metal mold must be processed first. The selected metal material (such as cast iron, cast steel) is placed in a furnace for smelting. For example, cast iron flanges are generally smelted in a cupola or electric furnace, where the cast iron material is heated to a molten state, and the temperature and chemical composition must be controlled during the process.-Workers cut and roll flanges using production technology-First, workers will cut the general shape of the flange on the middle plate by flame cutting or plasma cutting according to the flange size, and reserve a certain amount of processing allowance. The cut flange blank will be processed on the machine tool for bolt holes, water lines, etc., and the flange will meet the finished product standards through drilling on the drilling machine and processing of water lines on the lathe.-Innovative forging products lead the industry development-Recently, as a company specializing in the manufacture of forged products, our company has once again launched a series of innovative products based on years of technical accumulation and industry experience, further consolidating its leading position in the industry. The company is committed to providing customers with high-quality forged products, which are widely used in aerospace, automobile, petrochemical, energy and other fields.-Innovation drives the development of forging industry-Dingxiang County, Xinzhou City, Shanxi Province - Dingxiang Liantai Flange Co., Ltd. has been committed to technological innovation and market expansion in the forging industry since its establishment in 2012. With years of technical accumulation and industry experience, the company has continued to grow and develop, rapidly growing from a start-up factory to a leading forging product manufacturer in the industry.

Our workers will use forging tools such as air hammers or electro-hydraulic hammers to perform operations such as upsetting and drawing on the heated billet. For example, upsetting is first used to reduce the height of the billet and increase the diameter, and then drawing is used to adjust the size of the flange. For flanges with holes, punching operations are also required. If it is die forging, workers will first put the heated billet into a pre-made mold, and apply pressure through a press to form the billet in the mold. The die-forged flange has higher dimensional accuracy.

For the forged flange blank, use a cutting device to cut off the excess burrs. For flanges with holes, precise punching operations are also required to ensure that the size and position of the holes meet the requirements.

Workers put the flange into a heat treatment furnace for heat treatment such as normalizing and tempering to improve the mechanical properties of the flange, such as improving strength and toughness. The sealing surface, bolt holes and other parts of the flange are processed on the machine tool. The sealing surface of the flange can be processed by a lathe to achieve the specified flatness and finish; the bolt holes are processed by a drilling machine to ensure the accuracy of the holes.
