Additional, die casting aluminum are used both in the pivotal military sector as well as commercial. The reason for this is easy – they are cost-friendly solutions and provide amazing outcomes.

Apart from being cost effect, the parts made from die casting aluminum are additionally prepared to endure extreme weather situations and increased damages. Another vital reason for using aluminum products in aircraft is that the meal is comparatively affordable than other metals that are die casted. Additional,  aluminum has the potential to get with other metals in order to provide durability and much flexible.

die casting parts

With aluminum casted products, you do not have to compromise on the standard yet can them at much affordable production cost. Further, all the standards that have been set for using of metal components, aluminum relax the need to the utmost. Hence, they are certified secure for use in planes, affordable and have all the qualities that are needed for flying crafts. So casting aluminum is on the boost like never before. Further, the top thing about an aluminum die cast part is that its weight is favorable for the aircraft works.

So, how actually is casting Aluminum done and what are the processes involved? Well, the reply is simple. Aluminum alloy is first forced into a top-grade steel at high speed and force in a high temperature. This outcomes in superior standard products that are very light and thin walled perfect for use as aircraft components.

It is to be mentioned here that Aluminum diet casting is a hard technique. Only a truly experienced and top standard team of engineers can make sure that the parts come with top volumes or with excellent tolerances and surface finish. Actually, this type of force casting is far more famous than gravity die casting or sand casting. This is because the need for machining is this type weather for Zinc or aluminum casting is extremely low due to the close casting tolerances. Though the tooling cost in casting Aluminum or rather any metal are considerably higher than the other 2 types yet, the mechanical properties achieved thus are far excellent in terms of functionality.

Zinc die casting

What is Die Casting?

Die casting is a metal casting process which is characterized by pressing molten metal into the mold cavity. The mold cavity is made using two hardened tool steel molds that are worked on during processing and work similarly to injection molds. Most die-casting is made from non-ferrous metals, especially zinc, copper, aluminum, magnesium, tin, lead, and tin-based alloys. Depending on the type of metal being thrown, a thermal or cold engine is used.

Zinc die casting

Zinc die casting

The zinc die casting process is very popular for making parts in building and industrial fields, but the most common application is in the automotive industry. In fact, cars have different parts that can be made through die casting, in such a way that the modern process of die casting was originally started for the automotive industry.

With the casting process often no further machining is needed after casting: not only is the accuracy up to 99.8%, but the casted products can also be used raw because they have a pleasant finish. The use of zinc die casting is almost 28% in the automotive industry, followed by the building and hardware sector.

Zinc has become one of the most important metals in the auto parts industry, especially for products such as door lock housing, pawl, gears and retractor pulleys in seat belt systems, but also for camshaft and sensor components. By using this metal and its alloys, it is possible to achieve strength, ductility, and flexibility that would not be possible with other materials.

In addition, zinc can be the right choice to get high-quality aesthetic components, with tight tolerances that are not possible with other materials, and to get embossing and grooves for mechanical components or gears.

Zinc Die Casting Mechanisms in Automotive

As said before, the automotive industry is the most common die casting application: using zinc and its alloys makes it possible to produce components that are able to achieve high aesthetic quality, with tight and narrow tolerance for shape morphology. Zinc alloys are also used for coatings because of its many benefits, such as improving the anti-corrosion properties of zinc which are already impressive.

The climbing phase:

  • The 1st step is to prepare the die halves for casting by cleaning the faces of each die then applying lubrication or release agent.
  • Once the die has been prepared, the die halves are closed and clamped together with pressure applied from the die-cast machine.
  • The clamping force will depend upon the size of the machine but must be more than the opposing force trying to open the die during the casting process.Die Casting manufacture company

The injection phase:

  • The ingots are added to the furnace and kept molten at a set temperature according to the metal being used.
  • The molten metal is transferred to an injection chamber and injected into the closed die pressure ranging from 1000 to 20,000 psi.
  • The pressure is maintained while the metal solidifies.
  • The amount is injected into the die is known as the ‘shot’
  • The injection of metal into the die is very short, this ensures the metals do not start to solidify before the die is completely filled.

The cooling phase:

  • After the injection is complete, the molten metal needs to solidify before the die is opened.
  • The cooling time will depend upon the part geometry as well as the metal thermodynamic properties.
  • The wall thickness of the parts plays a big factor in the cooling time, the thicker the wall section the longer the cooling time required.

The ejection phase:

  • After the cooling time has elapsed, the two die halves can be opened.
  • An ejection mechanism then pushes the solidified casting out of the die.
  • The force of the ejection will be determined by the size of the part, bearing in mind, the part shrink during the cooling process and tends to stick to the die surface.
  • Once the part has been ejected, the die can be closed ready for the next injection cycle.

The trimming phase

  • During the cooling and solidification phase, the casting will solidify as a complete cast unit which includes the part, flash, and any runner system
  • This excess material must be trimmed off to leave just the main cast product.
  • Method of trimming includes trim tools, band saw are manually clipping.
  • Any trimmed metal is either scrapped or recycled if permitted.

Advantages of die casting:

  • Die casting is fast

Die casting can be produced in seconds each part and quantities of hundreds to thousands of metal parts each day.

  • Near net shape

Die casting are produced “near net shapes” no matter how complex the shape are how tight the tolerances are.

  • Lighter weights

Die casting are stronger because of the material surface skin not the thickness of materials so parts can weigh less with thinner casting wall thicknesses.

  • Die casting is versatile

Many more part shapes and sizes can be produced using the die casting manufacturing process.

  • Die casting are durable

Die castings parts are metal and have a long service life.

  • Die castings are inexpensive

Die castings are fast to produce and useless material. Die casting are typically less expensive than most other metal parts manufacturing processes.



Zinc die casting

The process of die casting with pressure injection can be followed until mid-1800. The components used were tin and lead, but the use has disappeared with the introduction of zinc and Aluminium alloys. This process has evolved over the years, from low-pressure injection molds to casting molds at pressures of up to 4,500 psi. The process can create high-quality products with excellent end surfaces.

Die Casting is an economical and efficient process for making various shapes. Considered superior to other manufacturing techniques, it is durable and aesthetic and combines perfectly with other parts of the machine that are part thereof. Dying has many advantages. Among these, the main is its ability to produce complex forms with a higher tolerance level than other mass-production methods. Thousands of identical prints can be produced before you need to add new mold tools.

Zinc die casting

High Die-pressure is a manufacturing process where aluminum that has been melted is injected by a casting machine under extreme pressure on steel or molds to make the design and detail parts of the model you want to make. Casting in tons of universal tightening. This record reflects the amount of pressure given on the matrix. The engine size varies from 400 to 4000 tons.

There are many advantages to using the die casting process compared to others. Die casting produces parts with thinner walls, narrower size limits and processes can be accelerated. Labor costs and finishing are the lowest with the dice. This process facilitates to obtain intricate forms with narrower tolerances. Unlike the forgery process, you can insert the kernel into the product created by this process.

Forms that cannot be obtained from rods or tubes can be easily achieved with casting. The number of operational processes is smaller, which leads to the reduction of waste materials.

Die casting is used when you need a stable, dimensional and durable component. They withstand heat and maintain a good level of tolerance, an important condition for each part of a good machine. They are stronger and lighter than the part made by other printing methods. Its parts are not welded or screwed, which greatly increases its efficiency. Another advantage is the many workarounds that you can get with the launch. Surfaces can be smooth or textured, which facilitates the application and its use.

Hopefully, this information can help you and thank you for reading the article about Zinc Die casting.

aluminum casting and machining

Metal casting is highly crucial in modern manufacturing. It is technically shaping the whole world. As you know, you can create a wide range of metal parts from this method. High Pressure Die Casting is one of the most popular metal casting methods here.

A typical metal casting method pours molten metal into a mold to create complex and precise shapes. Every industry needs these casting parts for many applications. They may need them for structural support or in their main products.

One popular way to shape metal is through die-casting, and high pressure die casting is one of the most common die-casting methods. This method is what this article is mostly about. You will learn about how they are made, their benefits, and how they can be used. You will also find out how HPDC and LPDC are different.

high pressure die casting

Overview of High Pressure Die Casting (HPDC)

HPDC stands for High-Pressure Die Casting. As the name suggests, this metal casting method needs high pressure. HPDC casting is suitable for making many metal parts with high tolerances.

In HPDC die casting, molten metal is injected into a steel mold or die at high speeds and pressure. As a result, you can create hundreds of casting parts in less time. The pressure needed here is to ensure that the molten metal fills the detailed feature of the die. Because of this, high-pressure die casting is suitable for high-volume production.

An high pressure die casting machine is made up of several primary components. All of them are very important to the system. You might also find other parts, though. However, these four parts are the most important things in high pressure die casting process. They usually decide how good the casting parts are in the end.

Die Cast Molds

Die-cast molds, or dies, are high pressure die casting machine parts that generally determine the final shape. They have two main halves: stationery and movable. They are usually made from high-strength steel. Making these HPDC die-cast molds is called high pressure die casting tooling. Note that HPDC tooling is crucial for the best quality of metal casting.

Ejector Pins

Ejector Pins are another important components in high pressure die casting mold. They facilitate the removal of the solidified cast from the die. You can find these pins within the movable die half. Once your metal casting is cooled and solidified, you can actuate these pins to remove it. It mainly plays a crucial role in the production cycle.

Cold chamber die casting machine

Cold chamber die casting machine is a most important machinie which has injection system, press system, ejection systems and so on. all of die casting process will be done by this cold chamber die casting machine.

Heating Components

Heating components may include furnaces and heating elements. They typically do not melt the metal but keep the temperature constant. The main goal of this high pressure die casting machine part is to ensure the metal is in liquid form. Note that consistent heating is crucial for the quality and consistency of the final castings.

How DoesHigh Pressure Die Casting Work?

Generally, high pressure die casting works in five steps. Each step is crucial for the final quality of the castings. Therefore, when starting a die-casting process, always inspect the device. Check for any defects or loose screws. Always tune your device to its optimal settings. Check whether the cooling system is properly working or not.

Once you have checked your device correctly, you can proceed to the primary high pressure die casting process. Always wear safety gear, such as gloves, clothes, and glasses.

Step #1 Preparing the Die Cast Mold

You can prepare the high pressure die casting mold in two main steps. First, if it has already been made, check it for defects and contamination before using it. Second, designing the mold is necessary for customized products.

Designing a die-cast mold has several stages. First, you can draw your design using 3D software like SolidWorks, AutoCAD, and more. Ensure you have properly organized the gate runner and mold base when designing it. The cooling system is also a crucial part of this design process. Finally, check the venting & ejection system.

Once you are done with the design, proceed with the draft analysis. You can check its functionality on various simulation software. After testing and quality inspection, you can use the die casting tooling for your final production.

Step #2 Molten Metal Injection

In this HPDC casting process, the machine injects molten metal into the die cavity. Unlike other methods, high-pressure casting uses high pressure and speed for this job, which is why it is called high-pressure die casting.

First, tightly connect the two halves of the die-casting mold. Then, with a button push, the HPDC machine forces the molten metal into the chamber. This pressure technically ensures that the molten metal fills the entire cavity. Once the injection is done, the molten metal is allowed to cool and solidify.

Two primary injection methods are used in the HPDC die-casting system. You can choose the correct method for the job based on your project needs.

Hot Chamber Injection

When your injection mechanism is immersed in the molten metal reservoir, it is called hot chamber injection. When the plunger moves, it draws the molten metal into the chamber and injects it into the die cavity. This type of injection is suitable for metals with low melting points. You may often find this hot chamber die casting machine is used zinc and magnesium alloys.

Cold Chamber Injection

Cold chamber injection, on the other hand, uses a separate melting furnace. You can pour the molten metal using a manual or automated system. In manufacturing, the automatic system is generally operated by a hydraulic plunger. It forces the molten metal to insert into the mold cavity. Cold chamber injection is a common technique for aluminum HPDC casting.

prototyping CNC machining

Step #3 Cooling & Solidification

After injection, the molten metal quickly cools within the die cavity. Some factories, like CNM TECH, use controlled cooling. During this time, you must ensure proper solidification.

Note that adequate cooling is mainly necessary to avoid defects. As you know, several defects occur due to inappropriate cooling. Some defects are hot spots, cold shuts or misruns, shrinkage, and porosity.

Cooling channels within the die typically stabilize the temperature. You must ensure these cavities are correctly designed when designing a die-cast mold. At CNM high pressure die casting Factory, our experienced engineers always test these cooling systems. Thus, our metal casting has almost zero defects.

Step #4 Ejection

Once the metal alloy part has cooled and solidified within the die, eject it using the ejector pins. Carefully do this step to avoid any external damage. The ejector pins usually facilitate this removal process. They are on the movable part of the die-cast mold.

Step #5 Trimming & Finishing

After removing the metal part, you may find some extra material on the body. You may need some additional finishing processes to get it in good shape. You can perform trimming, grinding, or other surface treatment methods.

The trimming method usually removes excess material from the metal part. It can be manual or automated. However, a smooth surface may need grinding, sanding, or machining. These methods can help you achieve the desired dimensions.

If you need more finishing, you can use different aluminum surface treatments. There are many ways to do this. These techniques can help your HPDC casting parts be more robust and less likely to rust. The most common methods are black or clear anodized aluminum, painting, powder coating, e-coating, and more.

After all this, your HPDC casting parts may need testing for certifications. Note that certifications create customer trust and reliability in real applications.

What are the Key Features of High-Pressure Die Casting?

In the previous section, we discussed the HPDC die-casting process in detail. As you know, in the HPDC casting process, the machine pours molten metal into the die or mold cavity at high pressure and speed. This technically provides several advantages. Let’s check them one by one.

This means that these molten metals can reach every detail of the design. Most aluminum intricate metal parts are made through the HPDC casting process.

Feature #3 Better Surface Finish

The HPDC casting process also produces a better surface finish. The molten metal fills every corner of the mold cavity under high pressure. Because of this pressure, the density of the metal part also remains the same. Because of this, the surface gets a better result after it cools.

Feature #4 Increased Productivity

The high-pressure die-casting process works very fast. In some manufacturing, this process is fully automated. However, whether manual or automated, it is still faster than other methods. Because of this, you can make hundreds of metal parts in less time. This increases your productivity and reduces costs.

Feature #5 Work with Thinner Wall Products

Again, the high-pressure molten metal fills every corner of the mold cavity. This technology allows you to work with thinner-walled products. Some typical examples are engine components, housings, and heat sinks.

Feature #6 Better Quality

High-pressure casting parts are famous for their high quality and consistency. The controlled process parameters and precise molds always give you uniform castings. This consistent quality ensures better mechanical properties. Specifically, the casting metal parts can have more strength and durability.

Feature #7 Durable Dies

Finally, the tools used in HPDC casting are usually made of good steel. These molds or dies can easily handle high pressure repeatedly. Overall, durable dies eliminate the need for frequent replacement. Once created, they can make thousands of metal parts repeatedly, reducing production costs.

Different Between Aluminum Die Casting and Gravity Casting

Aluminium Die Casting is more than just an excuse to play with the molten metal it is actually a great way to create art and complicated pieces of machinery or other items that would otherwise be nearly impossible to make. Aluminum die Casting is really a great way to save money…while playing with molten metal.

The reason that aluminum die Casting has survived the test of time is a matter of efficiency. Some of the earliest casting examples have been found in China dating back thousands and thousands of years. In fact, every major civilization from the Egyptians to the Romans practised aluminum casting. This skill came back into vogue during the Renaissance and has continued to advance and evolve from there. While Sand Casting is the most popular casting process there are many, many more processes available to the backyard foundries.

Not everyone is going to be casting heavy pieces like engine parts or cast their own motorcycles. So for those that just want to make decorative pieces, you will not be using the same casting process as these heavy duty casters.  For artists creating small scale statues or embellishes and for hobbyists that need a decorative touch to their model plane or boat might want to consider using gravity casting for their needs.

What is Gravity Casting

Gravity Casting seems to be especially useful when dealing with aluminum and other light alloys. The basic idea behind this casting process is pretty much exactly what the name suggests. The metal is introduced into the mold by the force of gravity. Most other casting process either use natural pressure difference like the kind in certain sand casting procedures or they use forced pressure like in centrifugal casting to get the molten metal into the mold.

One of the most common uses for gravity casting is when permanent molds are going to be used. Also called a die, the permanent mold is really only economical for those planning on using the same mold numerous times and will need to keep the quality at a constant level. While some temporary molds can be repeatedly used the quality of the finished product will begin to suffer over time. With die molds the quality will remain the same. Die molds should be seen as an investment. Yes, they will be more costly than other molds; however, they will outlast cheaper options for molds. With Permanent molds, they are created using cast iron, steel, and other metals.gravity-casting

Gravity casting is used for the permanent mold process with pleasing results. Gravity casting is usually used when the finished product is more visually based then structurally based which is why this method is a favourite of artists and even some jewellers. The loss of strength is due to the lack of pressure used in this process. For those that need the strength but still want to use gravity casting, more of the molten metal will need to be used which will increase the weight. go to to know more about gravity casting

Relying on gravity will take patience, although it will be needed for larger products.

Magnesium Die Casting

Casting is a process in which molten metal is poured into a mould that contains the intended shape. High pressure die casting (HPDC) is the most common method of Magnesium Die Casting and its alloys.

Magnesium is melted at a temperature of 923K and poured into crucibles where it is cooled under high pressure. The cooled magnesium solidifies and takes the shape of the crucible.

Magnesium has an inflexible hexagonal structure at its basic atomic level which makes it difficult to roll, stretch and shape. HPDC overcomes this limitation by offering an alternative, less difficult and faster method for manipulating

Uses of Magnesium die casting

Magnesium is increasingly used in automotive and airplane manufacturers. This is due to its lightweight per unit volume. Casted Magnesium is also used in the manufacture of lightweight car seats, car bodies, and fuselage parts. The use is attributed to Magnesium is the lightest structural metal which can withstand greater column loading per unit weight.

Magnesium and its alloys are being used to manufacture chassis for appliances such as laptops, cameras, and phones.

Magnesium castings are also used in the manufacture of power tools such as chain saws, electric drills, and electric nail guns. The use of electrical appliances is gaining ground owing to its ability to conduct heat and electricity.

Advantages of high pressure die casting

Magnesium casting offers good finishing characteristics as minute details can be impressed onto the final product. High pressure dies casting is more economical compared to other methods of shaping Magnesium.

In this green era, the ability to recycle Magnesium makes High pressure die casting an environmentally friendly process. Magnesium metal is almost 100% recyclable thus reduces industrial junk.

Casted Magnesium alloys have high conductivity. There is marked improvement in the electrical and thermal conduction capabilities in Magnesium alloys making them suitable for use in electrical and thermal appliances.

Magnesium and its alloys can be cast into various shapes suited for different uses; Casting into thin walls can be achieved. Since Magnesium saves on weight without reducing durability, Magnesium thin walls are relatively stronger and lighter as compared to other metals of the same volume.

It has been noted that molten Magnesium has reduced affinity to iron thus can be cast in iron crucibles with a reduced risk in the final product acquiring iron impurities.

Casted Magnesium is resistant to corrosion by the elements, most notably, is the reduced susceptibility to Hydrogen porosity.

Disadvantages of high pressure die casting

Due to its very high melting point, melting Magnesium is both dangerous in safety and expensive process. A lot of energy is required to melt the Magnesium thus increasing the cost of production.

Moreover, the very high molten temperature of Magnesium can cause the liquid metal to take some of the iron from the crucible. Acquiring iron from the crucible is often undesirable as it would make the final product relatively impure.

Molten Magnesium is more viscous than other metals such as Aluminum. As a result, more pressure is required in the cooling process in an attempt to acquire the intended casting detail since cooling is often done under pressure.

To produce Magnesium die casting has high risk than producing Aluminium die casting, Magnesium is easy to get on fire since the ignition point is very low and it is hard to control this. this is why the cost is more expensive than Aluminum die casting. contact us to know more info.
