Description
The following is an Introduction To Sand Casting. Sand casting is one of the most popular and simple casting types, which has been used for several centuries. The sand casting cost is very reasonable, which greatly saves costs for manufacturers. Sand casting also has other advantages, such as the casting size can be varied, small enough to be placed in the palm of the hand, large enough to accommodate train carriages. With this method, most metals can also be cast. Of course, it depends on the type of mold and sand.

Knowing the Introduction To Sand Casting, there are other knowledges you should know about this method. Sand casting requires only a few days or even weeks of lead time. This method makes high productivity (1-20 molds/hour) possible, which is a very good choice for large part manufacturers. Wet sand is black, with almost no weight limit, while the actual weight of dry sand is limited to 2300 – 2700 kg (5100 – 6000 lbs). The minimum part weight range is 0.075 – 0.1 kg (0.17 – 0.22 lb). Sand is bonded with clay, chemical adhesive or polymer oil (such as engine oil). In most operations, sand can be recycled multiple times with little maintenance.
