Precision casting technology in China has a big heat, in the case of imported before the people trying to make their own technology, have their own casting industry, so in the future we should know more precision casting technology to gradually improve and refine, below is for everyone to analysis precision casting need some technical conditions.Precision casting accuracy requirement and cost:All kinds of casting method for precision casting, initial investment and productivity is not consistent, the economic effect Yi also have differences.Therefore, to do more, faster, better, the province, all aspects should give attention to two or morethings arrives.To cope with the selected by casting method carries on the preliminary cost estimate, to determine the economic benefit is high and can ensure the requirements of the casting foundry method.
