杭州汽车发动机厂的6130柴油机机体铸件原用Ｚ2316造型机加风舂紧实造型,由于砂型紧实度低且不均匀,外形尺寸精度差,铸件经常出现严重的涨砂、粘砂现象,铸件表面粗糙,外形尺寸超差较大,废品率较高。同时还存在生产效率低,机器损坏快,维修工作量大等一系列问题。随着生产发展,要 Hangzhou Automobile Engine Factory 6130 diesel engine body casting Z2316 original molding machine with wind 舂 compact shape, due to low and uneven sand compactness, poor dimensional accuracy, castings often appear serious up sand, sticky sand phenomenon, the casting surface Rough, large size tolerance, rejection rate higher. At the same time there are also a series of problems such as low production efficiency, rapid damage to the machine and heavy maintenance work. With the development of production, we must
