我厂于1987年从西德BMD公司引进了BMD空气脉冲造型机。该机不需震捣、压制及其它机械、物理和化学的方法,而是靠压缩空气的膨胀力压紧砂型。其主要优点:砂型均匀,铸件尺寸稳定,与震实造型机相比可节省铸件重量8％,余砂和散砂少,型砂密实度容许公差范围大,能源消耗少,生产成本低。 主要技术数据如下: 造型机 CHL80·60 造型箱 800×600×300/300 输出 80～120箱/h,可调 循环时间 30s 浇铸时间 26s I plant in 1987 from West Germany BMD introduced BMD air pulse molding machine. The machine does not need to vibrate, suppress and other mechanical, physical and chemical methods, but by the expansion of compressed air compression sand. Its main advantages: uniform sand, casting size and stability, compared with the shock molding machine can save casting weight of 8%, less sand and sand, sand tight tolerance tolerance range, less energy consumption, low production costs. The main technical data are as follows: Molding machine CHL80 · 60 Modeling box 800 × 600 × 300/300 Output 80 ~ 120 boxes / h, adjustable cycle time 30s Casting time 26s
