The engineering technology brief introduction that nicety casts
Science and technology is the first productivity, as the reforming and opening that comes nearly 30 years, industry got developing quickly, because this also had good development opportunity,nicety is cast, nicety casts wide application to be carried at spaceflight, electron, oil, chemical industry, traffic, instrument, shipbuilding and in each industries, no matter be the demand of modern industry, the demand that still is agricultural machinery and the need that live daily cannot have done not have the existence that nicety casts.
Opposite at conventional foundry technology, nicety is cast can obtain well and truly appearance and taller cast precision. Alleged and accurate foundry technology, say simply even if make model of Cheng Kerong with Yi Rong material, on its Tu Fure does a tailor-made fireproof painting, the course is dry after forming a whole hard surface with sclerosis, reoccupy vapour or hot water from model the frit in housing drops a model, next model in housing park sandbox, in its all around fill does arenaceous model, put casting mould into roast furnace to pass high temperature roast finally, casting mould or model after housing classics roast, at among them pouring melt metal and receive cast.
