In the field of electric power and energy equipment manufacturing, large castings are facing the double challenge of \"both rapid innovation and stable batch production\". This kind of \"big, fine, difficult\" castings are not only huge size, but also on the airtightness, strength and dimensional accuracy has nearly demanding requirements. The traditional manufacturing method is caught in a dilemma: if the pursuit of rapid innovation, the use of wooden mold trial period is shorter (about 40 days), but can not meet the stringent precision requirements of the product, but also can not meet the requirements of mass production of the quality and stability; if the direct opening of the metal mold, it is a huge investment in the early stage (mold costs more than 500,000 yuan), and the design of the high cost of change. This contradiction seriously restricts the iterative speed of power equipment, especially in the current industry to accelerate the green, intelligent transformation of the background, the traditional process has been difficult to meet the market demand for rapid product upgrading.<\/p>\n\n\n\n
