Is the casting suitable for pressure casting production?

Casting methods, casting methods of different castings are also different, commonly used is sand casting, followed by special casting methods, such as: metal casting, investment casting, gypsum casting, etc. Sand casting can be divided into clay sand type, organic binder sand type, resin self-hardening sand type, lost mold and the like.

Principles of casting method selection:

1 Sand casting is preferred, mainly because sand casting has lower cost, simple production process and shorter production cycle than other casting methods. When the wet type does not meet the requirements, consider using a clay sand table 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, while clay dry castings can weigh up to tens of tons.

2 The casting method should be compatible with the production batch. Casting methods such as low pressure casting, die casting, and centrifugal casting are only suitable for mass production because of the high cost of equipment and molds.

3 modeling methods should be suitable for factory conditions. For example, it is also the production of castings such as large machine bed, generally using the core forming method, not making the pattern and the sand box, and assembling the core in the pit; while the other factory adopts the sand box modeling method to make the appearance. Different enterprise production conditions (including equipment, site, staff quality, etc.), production habits, and accumulated experience are different. It should be considered according to these conditions what products are suitable and what products are not suitable (or not).

4 must pay attention to the precision requirements and costs of castings.
