Compared with sand casting, what are the advantages and disadvantages of investment casting?
Generally speaking, sand casting is low in cost, and has no special restrictions on product structure, complexity, casting material, and weight. It is the most versatile casting method and can meet machine tool accessories, mechanical hardware, automobile and motorcycle accessories, etc. The production of all kinds of castings can realize mechanization and automatic production mode. With the continuous development of casting technology and the use of high-precision casting molds, the precision level of sand casting has also been greatly improved. Therefore, in the world Sand casting is still the most widely used casting method. However, compared with investment casting, investment casting has higher casting precision, smaller machining allowance, and better surface rough plating. Investment casting is suitable for the production of high-precision small and medium-sized castings. The applicability is relatively small, and the cost is higher than sand casting. Therefore, the choice of casting method should be based on the actual requirements of the casting.
