Method for casting machine casting method is commonly used in sand casting, followed by the special casting method, such as: metal mold casting, investment casting, plaster casting... Etc.. But the sand casting can be divided into clay sand, sand, organic binder resin self hardening sand EPC, etc..

Casting method selection principle:

1, give priority to the mold casting, the main reason is that the cost of the casting mould casting method than other low, simple production process, short production period. When the wet type can not meet the requirement to consider using clay sand table dry sand, dry sand mold or other. The clay wet sand castings casting weight from a few kilograms until tens of kilograms, but the clay does the production of castings can be weighed dozens of tons.

2, casting method and the production batch should be adapt to. Low pressure casting, die casting, centrifugal casting foundry method, because the equipment and tooling is expensive, so only suitable for mass production. 3, the modeling method should be suitable for factory conditions.

For example, the same is the production of large machine tool bed casting, the general use of cores modelling method, don't make shape and sand box, in the pit of cores; and another factory used the sand box modelling method, and making the appearance. Enterprises in different production conditions (including equipment, site, the quality of the staff, etc.) production habits, experiences of each different, according to these conditions should be considered for what products and is not suitable for (or not) do what products.

4, machine tool castings casting method to balance the precision casting and cost requirements.
