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.

Below you can find a number of possible examples of zinc plating:

  • Interior aesthetic section
  • Sunroofs Section
  • Mechanical parts
  • Engine and other underhood components
  • Power steering system
  • Parts and brake system
  • Air conditioning components and systems
  • Chassis hardware

Advantages for Zinc Die Casting:

  • An efficient & economical process offering various forms & forms possible.
  • High-Speed ​​Production
  • Dimension Accuracy & Stability
  • Strength & weight
  • Several finishing techniques are available
  • Simple Assembly

The Die Casting process began with the use of lead and lead alloys, magnesium and copper alloys which were quickly followed, and in the 1930s, many modern alloys still in use today are available. This process evolved from casting low-pressure injection to modern high-pressure injection of 4,500 pounds per square inch. The modern process is capable of producing high integrity, clean casting forms with excellent surface finishes.

Zinc casting alloy is a strong, durable and cost-effective engineering material. Their mechanical properties are competitive and are usually higher than cast aluminum, magnesium, bronze, plastic and most cast iron.

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.

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 https://www.aludiecasting.com/ 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
Magnesium.

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.

Challenges and Limitations of Aluminum Die Casting

Although aluminum die casting offers many benefits, it also has some limitations and challenges, including the following:

  1. Production cost and complexity: The production cost of aluminum die casting can be relatively high compared to other manufacturing methods, mainly due to the high cost of molds and casting machines. The complexity of the process can also make it difficult to manufacture small quantities of parts efficiently.
  2. Environmental concerns: The process can generate significant amounts of waste by-products, such as emissions and wastewater. Manufacturers must implement appropriate environmental controls to minimize the impact.
  3. Limited alloy options: Unlike other processes such as investment casting, which can produce a range of alloys, die casting is limited to producing only a few aluminum alloys.

How to make aluminum die casting prototypes?

Aluminum die casting prototypes can be made by following these steps:

  1. Design the part: The first step is to create a 3D design of the part using computer-aided design (CAD) software. This design will be used to create the mold for the die casting process.
  2. Create the mold: Once the design is complete, a mold must be created. This can be done using a CNC machine to create the mold out of steel or aluminum.
  3. Select the appropriate aluminum alloy: Different aluminum alloys have different properties. Select the appropriate alloy based on the properties needed for the specific prototype.
  4. Prepare the furnace: Prepare the furnace and fill it with the selected aluminum alloy. Heat it to the optimal temperature, which will vary depending on the alloy used.
  5. Inject the metal: Once the temperature has been reached, the molten metal is injected into the mold cavity under high pressure. The high pressure helps to ensure that the metal is distributed evenly and accurately within the mold.
  6. Cool and eject the part: After the metal has been injected into the mold, it is allowed to cool and harden. Once it has cooled and hardened, the part is ejected from the mold.
  7. Finish the prototype: After the part is ejected from the mold, any additional finishing or machining can be done as needed to create a fully functional prototype.

The process of creating an aluminum die cast prototype is similar to the process used for creating a full production run. The main difference is that a more basic mold is used for the prototype, allowing for a much quicker turnaround time.

How to control the tight tolerance of aluminum die casting machining?

Controlling tight tolerances in aluminum die casting machining is crucial for producing high-quality and consistent parts. Here are some steps that can help control the tight tolerance of aluminum die casting machining:

  1. Proper equipment: Select the right machine tools and equipment that can achieve tight tolerances. High precision machines with advanced programming capabilities are necessary for maintaining tight tolerances.
  2. Process control: Maintain consistent process control by using a statistical process control (SPC) system that can detect variations in the process. The use of SPC will help identify and diagnose the sources of variation and control them.
  3. Material selection: Use high-quality materials that have consistent and predictable properties that will not interfere with the machining process.
  4. Tool selection: Select appropriate cutting tools, such as carbide, as they have excellent wear and heat resistance, and they are more precise than other materials.
  5. Tool maintenance: Regular maintenance of the cutting tools and CNC equipment is necessary for maintaining tight tolerances. The tools must be kept in good condition through frequent maintenance to prevent wear that may interfere with the tolerance of the parts.
  6. Quality Checks: Regular quality checks are essential to maintaining tight tolerances. Each part must be closely inspected to ensure that the required tolerances are met.
  7. Continuous Improvement: Continuously look for opportunities for improvement in the process. Apply the lessons learned from each part to improve future production, which will lead to better precision.

By following these steps, you can maintain tight tolerances in aluminum die casting machining, which can lead to the production of high-quality and consistent parts.
