Process:- Clamping: The first step is the preparation and clamping of the two halves of the die. Each die half is first cleaned from the previous Injection and then lubricated to facilitate the ejection of the next part. Also, lubrication may not be required after each cycle, but after 2 or 3 cycles, depending upon the material. After lubrication, the two die halves, which are attached Inside the die casting machine, are closed and securely clamped together.
- Injection: The molten metal, which is maintained at a set temperature in the furnace, is next transferred into a chamber where it can be injected into the die. The method of transferring the molten metal is dependent upon the type of die casting machine, whether a hot chamber or cold chamber machine is being used. The amount of metal that is injected into the die is referred to as the shot. The injection time is the time required for the molten metal to fill all of the channels and cavities in the die.
- Cooling: The molten metal that is injected into the the will begin to cool and solidify once it enters the die cavity. When the entire cavity is filled and the molten metal solidifies, the final shape of the casting is formed. The the can not he opened until the cooling time has elapsed and the c.ting is solidified. The cooling time can be estimated from several thermodynamic properties of the metal, the maximum wall thickness of the casting, and the complexity of the die. A greater wall thickness will require a longer coding time. The geometric complexity of the die also requires a longer coding time because the additional resistance to the flow of heat.
- Ejection: After the predetermined cooling time has passed, the die halves can be opened and an ejection mechanism can push the casting out of the die cavity. The ejection mechanism must apply some force to eject the part because during cooling the part shrinks and adheres to the die. Once the casting is ejected, the die can be damped shut for the next injection.
