Compared with sand casting, what are the advantages and disadvantages of investment casting?
The applicability is relatively small, the cost should be higher than the casting sand casting method. So the choice of more casting Ask for it
But the casting and casting is casting precision casting and higher machining allowance can be smaller. The surface roughness, better plating, small and medium sized castings suitable for high precision casting production.
Sand casting in general, low cost of product structure, complexity, casting material, weight, no what special constraints, is the most extensive casting method is universal, can meet the requirements of machine tool parts, mechanical hardware, auto parts production and so on all kinds of castings, and can realize the mechanization and automation of production mode, with the the development of continuous casting technology, the use of high precision casting moulds, the precision sand casting have been greatly improved, so the sand casting in the world is still the most widely used method.
