What is Auto Die Cast
One way in which manufacturers are achieving this goal is by using die castings. Automotive die casting uses a metal molding process to produce parts from molten metal (die). They then cool the metal and solidify it into parts such as engine blocks or gearboxes machined into shape.
Die casting is a method of metal fabrication in which the manufacturers press a piece of molten metal into a mold designed to produce the desired shape. Die casting uses two main components: a die and a cavity. The die is made from steel, aluminum, or other alloy and has a series of holes and channels machined into it to form the object that will be cast.
Benefits of Auto Die Cast
Manufacture of Lightweight Components
Manufacturing lightweight components are one of the most important reasons for automotive die casting. The use of die casting in manufacturing lightweight components has made it possible to reduce the weight of these components, which means that they can function in various applications such as cars and other vehicles.
Increased Automation and Flexibility
Manufacturers can produce die castings in large quantities, making them ideal for the mass production of vehicles. In addition to standard vehicle models, die castings are used to create components such as wheels, chassis, suspension systems, and body panels. These automotive die casting components can function in multiple vehicles or be sold as spare parts if their production runs exceed a manufacturer's needs for its inventory.
Enhanced Productivity
Die castings are more efficient than traditional manufacturing methods because they require less labor input per unit of product produced than those processes do. For example, one die casting machine can produce four times as many wheel hubs as another machine with the same number of operators working on it at any given time.
Multiple finishing techniques
Automotive parts of smooth and textured surfaces can be created with die casting. The parts can be quickly finished or plated with minimum surface penetration.
Automotive parts have different parts which could require different types of lightweight metals. The variety of die casting to work on various metals makes it a prime choice for machining these automotive parts. We've highlighted examples of the metals suitable for the process below:
Zinc
Zinc is the most common metal alloy used in die casting. In addition to its high strength and good corrosion resistance, zinc provides a good surface finish. Machinists use zinc to make dies that are suitable for use on many different types of molding machines.
Aluminum
Aluminum is another commonly used metal alloy for die casting. Alumina (aluminum oxide) is one of the major components of aluminum. It can serve as an additive to other metals to make them more durable or stronger. Aluminum alloys are common raw materials in the production of dies because they have excellent heat transfer properties and provide an excellent surface finish.
Magnesium
Magnesium is another commonly used metal for die casting. It has excellent strength characteristics and is an additive to other metals to create stronger parts. Alloys containing magnesium are also often used in producing dies because they have good thermal conductivity properties. This makes them ideal for use with high-temperature tools that require rapid cooling after completing machining operations.
The Die Casting Process Explained
There are two types of die casting processes; namely, the hot and cold die casting processes. Apart from the apparent temperature difference, these two processes also differ in their setup and operating pressure. We've explained each process in detail below:
Hot Die Casting
Hot die casting is another name for the hot chamber die casting method. The furnaces integrated inside the gooseneck machines used in this technique heat the metal till it melts. A hydraulically powered piston uses the nozzle and gooseneck to push the molten metal from the furnace into the die chamber. The molten metal is then kept in the die cavity under pressure until it solidifies.
There is an intrinsic melting point to this kind of die casting. As a result, it works better with metals with lower melting points. Aluminum is inappropriate for this process because of its high melting point of 1,220 degrees Fahrenheit. On the other hand, zinc and magnesium are suitable for this process because of their comparatively low melting points.
Cold Die Casting
The machinist pours the molten metal into the injection cylinder's shot sleeve during this procedure. After pouring, a hydraulic plunger pushes molten metal into the mold cavity without heating the sleeve. This technique uses pressure ranging from 30 MPa to 150 MPa. The method is known as "cold chamber die casting" since heat is not used. Aluminum alloys with high melting points work well using this method.
Automotive die casting components produced by cold chamber die casting have outstanding dimensional accuracy. Because the increased pressure, it also results in denser metal castings and automobile parts with greater strength. The procedure is simple to complete and costs less to maintain.
Application of Auto Die Cast
Manufacture of Lightweight Components
The automotive industry now has more stringent fuel economy standards. There is growing pressure to create more efficient vehicles. Therefore, automotive manufacturers employ aluminum die-casting to achieve this goal.
Aluminum is a lightweight metal with an excellent strength-to-weight ratio
As a result, it is the leading metal used for casting engine parts and wheels. Therefore, manufacturers now make lighter and safer vehicles by ensuring the quality of external and internal components.
Increased Automation and Flexibility
The popularity of automotive die casting continues to increase due to the growing use of advanced technology. Automation of the production process makes die casting more effective and productive, ensuring the creation of higher numbers of automotive die cast components.
Increased Sustainability of Components
Die casting for automotive parts also ensures the manufacture of eco-friendly and sustainable vehicle parts. Consequently, we can be sure of auto parts casting without causing damage to the environment. In addition, the ability to recycle the materials used for these components makes them even more valuable. For example, it is possible to recycle reclaimed aluminum indefinitely.
Steps of Auto Die Cast Process
The first step in auto die castis clamping. However, before then, clean the die to remove any impurities and lubricate the die for better injection and removal of the solidified product. After cleaning and lubrication, clamp and close the die with high pressure.
Melt the metal you want to inject and pour it into the shot chamber. The procedure depends on the process you are using. For example, the shot chamber is cold in the cold chamber die casting, while it is hot in the hot chamber die casting. After that, inject the metal into the die under high pressure generated by a hydraulic system.
While clamped, allow the metal to cool for solidification. The solidified material will have a shape similar to the design of the mold.
After unclamping the die mold, an ejection mechanism will push the solid casting out of the die. Ensure proper solidification before ejecting the final product.
This is the final step, and it involves the removal of the excess metal in the sprue and runner found on the finished product. Trimming is achievable using a trim die, saw, or other procedures. The removed metal parts are recyclable and reusable in the process.
