This technique is suitable for making large batches of small or large individual parts.
Die casting in the automotive industry enables the manufacturing of lightweight, strong parts with thin walls and complex shapes. It also reduces the stress often found in parts made through other methods, like CNC milling, giving engineers and designers more flexibility during the design process.
There are two main die-casting methods for making automotive parts: hot chamber and cold chamber die-casting machines. The choice of process depends on the material, size, shape, and complexity of the part. Let’s explore both methods to understand the difference between them:
In this technique, a gooseneck machine uses an internal furnace to melt the metal. A hydraulically powered piston then pushes the molten metal through a nozzle and gooseneck from the furnace into the die chamber. The molten metal is held under pressure in the die cavity until it solidifies. It involves heating metal until it melts, then forcing the liquid metal into a mold. This method is perfect for metals with low melting points, like zinc or magnesium. Aluminum is unsuitable for this process because it has a high melting point.
To fill a die cavity with molten metal, the operator pours the metal into a shot sleeve over the injection cylinder. The plunger then pushes the molten metal into the die cavity without heating the sleeve. Cold chamber die casting operates with 30 MPa to 150 MPa pressures. This method is ideal for high melting point aluminum alloys. Cold chamber die casting effectively makes automotive parts, producing dense metal castings and more vital components. It is easy to perform, requires less maintenance than other methods, and offers excellent dimensional accuracy.

Die casting methods are classified into two types: hot and cold die casting. Aside from the obvious temperature difference, these processes differ in setup and operating pressure. Each procedure is described in full below:
This die casting method is also known as hot die casting. The furnaces built into the gooseneck machines heat the metal until it melts. The nozzle and gooseneck of a hydraulically propelled piston are used to push molten metal from the furnace into the die casting chamber. The molten metal is then maintained under pressure in the die cavity until it solidifies.
This type of die casting has an inherent melting point. As a result, it is more effective with metals with lower melting points. Aluminum has a high melting point of 1,220°F. Thus, it is unsuitable for this method. Zinc and magnesium, on the other hand, are ideal for this technique due to their low melting points.
Hot die casting has a high production rate of over 18,000 shots per hour for small automobile components. Metals are melted within the casting machine, resulting in minimal material waste. Because it is a low melting point method, the die life is longer, which helps to reduce overall die casting costs. However, the technique is only cost-effective for large-volume productions. There is also poor metal fluidity, which limits the complexity of the goods.
During this technique, an operator pours the molten metal into the injection cylinder’s shot sleeve. Following the pour, a hydraulic plunger forces the molten metal into the cavity without scorching the sleeve. This procedure uses pressures ranging from 30 MPa to 150 MPa. Since heat is not employed, this approach works well with aluminum alloys.
Cold die casting produces automotive die casting components with exceptional dimensional accuracy. Because of the higher pressure, thicker metal castings and stronger vehicle parts are produced. The technique is simple to carry out and less expensive to maintain.
However, due to the transfer procedure, the cycle time is longer than the hot chamber method. There is also the possibility of excessive amounts of pollutants, which could compromise the quality of the final vehicle parts.
Here’s a table of comparison between the two die casting techniques:
hot chamber die casting vs. cold chamber die casting
