Casting belongs to a kind of molten metal mold molding technology, its our common casting methods are: sand casting;There are some special casting method, for example: metal mold casting, investment casting, plaster mold casting, etc.The foundry method must meet the following four points.
1, the priority using sand mold casting, the main reason is sand mold casting compared with other casting method of low cost, simple production process, short production cycle.When wet can't meet the requirements to consider using clay sand table dry sand, dry sand mold or other mould.Coatings for green sand mold casting can be from a few kilograms to tens of kilograms of weight, and clay dry production castings can weigh up to dozens of tons.
2, casting method with the production batch.Low pressure casting, die casting, centrifugal casting and other casting method, for equipment and mold is expensive, so only suitable for mass production.
3, modelling method should be suitable for factory conditions.
Also is the production of large machine tool lathe bed casting, such as, for example, generally USES the core modelling method, don't make shape and sand box, core in a hole in the ground;While other factories use sand box modelling method, production.Different enterprise production conditions (including equipment, sites, staff quality, etc.), production habits, accumulated the experience of each different, what should be considered according to these conditions suitable for products and is not suitable for (or not) to do the product.
4, to take into account the precision casting, and the cost.
Is about casting methods need to meet the above four points related introduction, hope can help to you.
