Manufacturing metal mold is much more expensive than manufacturing sand molds or investment casting process mold. Minimum number of castings for profitable use of a permanent mold is dependent on the complexity of its shape. Ferrous and noferrous metals and alloys are cast by the permanent mold casting process.

metal forming operation can always be, from the conceptual point of view, divided in two stages: • A first stage where the volume of the part is generated • A second stage where the geometrical details are formed (reverse drawing) In the first stage, deformation and material flow are mostly controlled by runoffs (die addendum or dieface). In the second stage, however, most of the

Pressing is the method of product manufacturing by means of metal extrusion through the die hole (Fig. 1.1, g). It is mainly used in nonferrous metallurgy and aviation industry where the shaped sections are produced from such materials as Al and Tibased hardtodeform and lowplasticity alloys. Sheet stamping is the method of metal plastic processing in which the sheet and strip bars are

Although this seems rather simple, the manufacturing process of metal casting is both a science and an art. Let's begin our study of metal casting with the mold. First, molds can be classified as either open or closed. An open mold is a container, like a cup, that has only the shape of the desired part. The molten material is poured directly into the mold cavity which is exposed to the open

Manufacturing – Casting methods using clean metal. The purification of the metal is implemented by permanent degassing and the use of filters. In order to prevent impurities during mold filling (in particular oxide inclusions), attention has to be paid to a uniform filling rate.
