The two types of casting machines are hot-chamber machines and cold-chamber machines.
Hot-chamber machines have a pressure chamber connected directly to the mold cavity, allowing for the continuous flow of molten metal into the pressurized compartment. These machines are also known as "gooseneck machines" due to the shape of their metal feeding system. They are commonly used for casting materials that have a low melting point, such as zinc and magnesium alloys.
On the other hand, cold-chamber machines do not have a direct connection between the pressure chamber and the mold cavity. Instead, the molten metal is ladled into a separate cold chamber and then injected into the mold cavity under high pressure. These machines are used for casting materials with higher melting points, such as aluminum and copper alloys.
Each type of casting machine has its own advantages and disadvantages, and the choice between them depends on factors such as the type of material being cast, the desired production volume, and cost considerations.
