Metal Die Cast in the Cold Chamber. In the field of metallurgy, the cold chamber process is known as one of the two major types of die casting methods. The other one is called the hot chamber process. If you see molded metal parts with a high melting point, they are most probably produced by a cold chamber machine. Cold chamber die castings might be made out of aluminum, magnesium, and copper.

These cold chamber die castings go through external furnaces. The metals are then poured into a cold chamber in the machine. The cylinder and plunger are not submerged in molten metal as is the process with low melting point metal alloys in a hot chamber process. These huge machines use hydraulic power to force the poured metal into the die mold. It is a slower process but the machines used for cold chamber die castings generally last longer. This and its ability to produce metals with a high melting point into precision parts make it useful for machinists, metallurgists, metalworkers, engineers, and manufacturers of our modern gadgets.

Die casting is only one of the processes used to shape metal to our needs. There is also forging, rolling, sintering, machining, fabrication, metalworking, and a number of different casting methods. Then there are the techniques of joining one metal to another which are soldering, welding, and brazing. There are also other techniques such as annealing, tempering, quenching, plating, thermal spraying, and case hardening. All these metalworking processes have contributed to the development of our world as we know it today.
