The Products Of Hot Chamber Die Casting Machines

There are many ways that you can work metals today but one of the most popular processes still in use has to be die casting. There are two ways to go about die casting. One of them is with the use of cold chamber die casting machines while the other one is with the use of the hot chamber die casting machines. Each machine and process will have its own sets of pros and cons but for now, hot chamber die casting machines and methods are what you will be reading about. This is a very interesting method that produces a lot of great results.

A little Intro on Die Casting in General

Generally speaking, die casting is a type of metal casing which functions with molten metal and gives them shape. Metal that has been heated from solid to liquid is as hot as lava and extreme caution must be taken during the whole die casting process. When engaged in die casting, there are some very important safety regulations that need to be followed so people and machines are kept safe and protected at all times. Die casting is a bit different than other metal casting processes since it needs a huge amount of pressure to be able to force the melted metal into the mold cavity.

Machines for Die Casting

You already know that there are two machines used for die casting. The cold and the hot chamber die casting machines but it is the hot chamber die casting machine that will be discussed here. The first thing you have to know about the hot chamber die casting machine is that it has a number of parts that get it to work the way it does. You will find a burner and a combustion area within the machine which generate heat intense enough to turn solid metal into molten steel. The liquefied metal then sits in a pool in what they call a pot or sometimes a crucible. These hot chamber die casting machines have an intake port which lets the molten metal get transferred into the cylinder which is situated under a plunger. On top of this plunger is the power cylinder which is where the pressure for the process comes from. These machines make use of either hydraulic or pneumatic pistons in their processes are also rated by the amount of force they are able to create. Hot chamber die casting machines use between 700 psi and 5000 psi or force which takes quite a lot of electricity to produce. These machines are also referred to as gooseneck machines, which is in reference to the shape of their nozzles.

Metals Suited for the Hot Chamber Process

You also need to know that only certain metals can be used in hot die-casting machines. One example of a metal suited for the hot chamber process happens to be zinc but other metals that have low melting points and do not attack or erode the metal components of the machines can be casted using this process as well. Some developments in technology and the use of advanced materials also mean this process can be used for some magnesium alloys as well.
