What is the purpose of casting?

Purpose of casting. The molding technique most often aims to manufacture objects in more or less large series. In pressure casting, the object once solidified can be released (demolding) without damaging the mould, and in sand casting, as many molds as parts are made (case of sand casting).

What is molding?

Molding is the action of taking an impression which will then serve as a mold in which a material will be placed and which will allow the printing or production of several copies of a model.

the most widespread techniques are, for the oldest, that of lost wax casting and for the most modern, polystyrene model casting known as the Lost Foam or PMP process.

What is the difference between die casting and sand casting?

In pressure casting, the object once solidified can be released (demolding) without damaging the mould, and in sand casting, as many molds as parts are made (case of sand casting). The casting workshop of the Cinquantenaire museum (Brussels).
