What principles should be applied when do casting?
2018-05-17 04:05:05

1 The better choice is to use sand casting. The main reason is that sand casting has lower cost, simpler production process and shorter production cycle than other casting methods. When the wet type can not meet the requirements, consider using a dry sand type, dry sand type, or other sand type. Clay wet sand castings can weigh from a few kilograms up to tens of kilograms, whereas clay dry type castings can weigh up to tens of tons.

2 The casting method should be compatible with the production batch. Low-pressure casting, die-casting, centrifugal casting and other casting methods are only suitable for mass production because the equipment and molds are expensive. 

3 Modeling methods should be suitable for factory conditions. For example, castings such as large-scale machine tool beds are generally produced by using a core assembly method. Patterns and sand boxes are not produced, and cores are placed in pits. In other factories, sand box modeling methods are used to make patterns. Different companies' production conditions (including equipment, site, and staff quality, etc.), production habits, and accumulated experience are all different. Based on these conditions, we should consider what products are suitable and what products are not suitable.

4 It is necessary to take precision requirements and costs of castings into consideration.
