【正文】 y cave die casting machine equally every eight hours but die casting 3000000。 Easy to realize mechanizing and automizing. economic result is fine Because the die casting is accurate in size, the form is suffused with the advantage such as being bright and clean. Generally no longer carry on machining and use directly, or the processing amount is very small, so has not only improve the metal utilization ratio but also reduced a large number of processing equipment and manhour。 Can adopt and make die casting up with other metal or nonmetallic materials . Assemble manhour save metal also sparingly. There are a lot of advantages in though die casting, but there are some shortings, to be solved. For instance: 1) Because one of speeds is high in the liquid metal filling with type at the time of die casting, the flow state is unstable, so adopt and generally press the casting method, the 南通職業(yè)大學(xué)畢業(yè)設(shè)計 (論文 ) 39 casting is apt to produce the air vent, not Can heattreat 。 3)High point alloy (such as the copper, ferrous metal), it is relatively low to press the lifespan of casting mould。 Weight can be from several grams to several dozen kilograms. But the diameter of die casting is 2m abroad, weight i
