美国IIT研究院研究成功一种新工艺,叫做针料等温热压.等温热压工艺是将废金属熔化后形成针形材料,然后用普通的压机等温压制成零件或压坯.这种工艺的优点是原材料便宜、工序少、设备成本低、无污染、耗能少、制品质地好.可用于生产汽车、农机等的小零件.废料可在空气中熔化,然后浇注在旋转的杯中,杯体上有许多小孔,金属液在离心力下 The United States IIT Institute of successful study of a new technology, called the hot isothermal pressing needle.Isothermal hot pressing process is to form a scrap metal melting needle material, and then use ordinary isothermal pressing into parts or compact. The advantage of this kind of craft is that the raw material is cheap, the procedure is few, the equipment cost is low, it is non-polluting, consumes less energy, the product quality is good. Can be used for producing small parts such as car, agricultural machinery, In the cup body has many small holes, the liquid under centrifugal force
