Process
· In die casting, mainly non-ferrous alloys are cast at high-speed and under high-pressure in permanent molds made of steel where they quickly solidify.
· The metal melt is introduced into the mold by a piston at pressures of up to about 1200 bar. For this purpose, form-closing forces in the range of several tens of thousands of kN are required.
· Due to the high-pressure even the finest details are formed.
· The cost-intensive molds enable economical die casting only if the volume is sufficiently high.
The method is used when a large number of uniform parts with a fine surface finish are to be manufactured (serial production). The die casting machine makes this process extremely economical, since besides the high dimensional stability of the cast part time-saving and cost-effective mass production is possible. Depending on the material several ten thousand to one hundred thousands of castings can be produced with one die casting mold.
The die casting process consists of 5 basic steps
Clamping
The first step in die casting is clamping. The dies are cleaned and lubricated to aid in step two, injection. Once the dies have been properly cleaned and lubricated, the die halves are closed and clamped together with high pressure.
Injection
The molten metal is transferred from a furnace into a ladle. The ladle then pours the molten metal into shot chamber where it is ready to be injected into the clamped die. The molten metal is then forced into the die using extremely high pressure. The high pressure then holds the metal in the die until it has time to solidify.
Cooling
The third step in the process is cooling. After the molten metal is injected into the die, it must have time to solidify and cool. During this time the die cannot be unclamped. Once the metal has completely cooled it takes on its final shape of the casting.
Ejection
Once the cooling process has finished, the die halves can be unclamped and an ejection mechanism pushes the solidified casting out of the die.
Trimming
The final step in the die casting process is trimming. While the metal is cooling, the excess metal in the sprue and runner must be removed along with any flash that has transpired. This extra material is then trimmed away from the final casting. The trimmed sprue, runners, and flash can then be recycled and reused in the die casting process.
