Cold Chamber Die Casting

Cold Chamber Pressure Die Casting

When it comes to manufacturing precise and accurate castings, precision die casting is one of the most efficient ways to ensure a consistent and high-quality end result. Cold chamber pressure die casting is a form of precision die casting that is preferred when working with metals that have a high melting point, including copper, brass, and aluminum.

The process helps to create stronger parts than those made out of plastic injection moldings with the same directions, ensuring durability and strength in your equipment. Cold chamber die casting is also known for producing stronger and denser metal casings that are suitable for long-lasting use such as for the automotive industry.

How Cold Chamber Die Casting Works

Cold chamber die casting is a process where metal is injected into a cold chamber, or cylinder, that is attached to the injection system of a die casting machine. The first step in the cold chamber die casting process is to heat the metal to its melting point. The melted metal is then poured into a cold chamber, where it is injected into the mold under high pressure. Once the metal has cooled and solidified, the part is ejected from the mold. 

Cold chamber die casting can be a complex process, and only the best materials will be able to withstand the high temperatures and pressures involved. If you are looking to produce parts with tight tolerances and smooth finishes, be sure to get a quote from EKO.

    Frequently Asked Questions About Cold Chamber Pressure Die Casting

    In hot chamber die casting, the injection mechanism’s cylinder chamber is completely immersed in the molten metal. This direct immersion into the metal enables a fast, convenient mould injection process that leads to higher production rates. In comparison, during cold chamber pressure die casting, the metal is heated separately in a furnace outside the machine before being fed into the casting chamber and being pressure cast into the mould.

    The process is a little slower compared to hot chamber die casting, as new material must be brought in from an external furnace at the start of each production cycle. The cold chamber process also requires much more pressure applied in order to fill the cold chamber with the right amount of molten metal.

    While there are some disadvantages compared to hot chamber die casting, the main advantage of cold chamber die casting is that the machinery stays cooler and can thus handle metals at a much higher melting point. This makes it suitable for die casting metals including zinc, aluminum, brass, and copper. Cold chamber process castings also have superior mechanical properties, with a smooth finish and thin falls. Both hot and cold chamber die casting are suitable for manufacturing precise castings depending on your specific industrial needs. Get in touch with us for more information.
