How many kinds of metal forming process

Common metal material forming process is the process of producing parts, for cold and hot forming, the common process is divided into the following categories, casting, forging, welding and cutting! Today, we will summarize these processes with diagrams and explanations.

Die casting (note that die casting is not the abbreviation of pressure casting) is a kind of metal casting process, which is characterized by using the mold cavity to exert high pressure on the molten metal. Molds are usually made of higher strength alloys, a process somewhat similar to injection molding.

Sand mold casting is to make mold with sand. Sand mold casting needs to put the finished part model or wooden model (pattern) into the sand, and then fill the mold with sand at the weekend. After the mold is taken out of the box, the sand forms the mold.

In order to remove the mold before casting the metal, the mold should be made into two or more parts; during the mold making process, holes and vent holes for pouring metal into the mold must be reserved to synthesize the gating system. After pouring the liquid metal into the mold, it is kept for a proper time until the metal solidifies. After the part is removed, the mold is destroyed, so a new mold must be made for each casting.

Stamping is a kind of forming processing method which uses press and die to exert external force on sheet, strip, pipe and profile to produce plastic deformation or separation, so as to obtain the required shape and size of the workpiece (stamping part).

The roll forming method is to use a set of continuous stands to roll stainless steel into complex shapes. The order of the rollers is such that the roll profile of each frame can continuously deform the metal until the desired final shape is obtained. If the shape of the parts is complex, up to 36 racks can be used, but for simple parts, three or four racks are enough.
