The difference and connection between hot chamber die casting and cold chamber die casting Cold chamber die casting and hot chamber die casting are variations of high pressure die casting process. Therefore, the hot chamber casting and cold chamber casting processes are very similar. However, their scope of application is different. This article briefly discusses the differences between these two processes in detail. Temperature range of hot chamber die casting and cold chamber die casting Hot chamber equipment for processing low-temperature non-ferrous alloys. The maximum temperature of alloys that can be safely die-cast in a hot chamber machine is around 450°C, including alloys such as zinc, magnesium and lead. In contrast, cold chamber equipment deals with high temperature non-ferrous alloys. It usually handles metal alloys with temperatures of 600°C or above, including alloys such as aluminum, copper, and brass. The position of the furnace The alloy melting furnaces are located in different locations and are used for both processes. The hot chamber device has a built-in furnace to melt the metal. Therefore, the metal is delivered directly through the gooseneck to the mold cavity. In the cold chamber die-casting plant, the melting furnace is located externally. The molten metal must be delivered to the machine using either automatic or manually operated ladles. Production time Hot chamber machines provide significantly higher casting cycles than cold chamber machines. Although both devices work very similarly, cold chamber casting has a longer cycle due to manual handling of melted metal. Die life The hot and cold room machines are built of the same materials. Low melting point alloy is used in hot chamber casting, which has little influence on the die. So, it lasts longer. In contrast, die conditions for cold chamber machines degrade faster because the molten metal has a higher temperature. The die casting alloy is melted in the furnace located inside the equipment, and the die casting alloy is melted in a separate furnace located outside the equipment. The melting and casting cycle of the die casting alloy is significantly shortened, so it has a higher production capacity. Therefore, the production capacity is smaller, suitable for high melting point alloys, has a shorter tool life and requires least safety measures requiring more safety measures. Commonly used metal alloys are zinc, lead and so on. Commonly used metal alloys are aluminum, copper, brass, magnesium and so on.
