Aluminium High Pressure Casting in its simplest definition is the pouring of molten aluminium raw material via a runner at high pressure (400-1,000 bar) and speed (30-100 m/s) into a mould made of metal. The process of applying high pressure is continued until the solidification process is completed. Thereafter, the mould is opened and the process is finished off by removing the part from the mould using forceps. After the process of spraying the mould with separator oil, the mould is sealed and locked again in preparation for the next cycle.

The part taken from the mould is cut off from the runner area and processed, heat treated, coated, etc. as needed to create the finished product.

There are two types of applications of the die casting process. The first of these is the Hot Chamber and the second is called theCold Chamber application. The Aluminium Material‘s structure and characteristics play a decisive role in which application should be chosen.

Hot Chamber Machines:

In the production of materials with a low melting point, such as lead, zinc and tin, Hot Chamber Machines are used. When using the hot chamber casting method, the accuracy rate for the finished product is ±0.05 mm at completion. There are two types of hot chamber casting machines which vary according to how they operate.

  1. Plunger Machines; The material in the crucible is melted and the construction comprises a cylinder which plunges into the crucible and which has a plunger inserted into it. This is how the process works for Plunger Machines. After the mould is closed, the plunger moves downwards, and the material that enters the cylinder is pushed into the mould.After the material solidifies in the mould, the plunger is pulled back and the mould is opened.
  2. Pressure Machines; The material that melts in the crucible is filled into the mould with a plunge cell and a lever system. Pressure Machines these are usually not the preferred method for aluminium casting.

Cold Chamber Machines:

Cold Chamber Machines are commonly used for the casting of high melting point alloys such as aluminium, copper, magnesium. In these machines, the melting furnace is located in a separate section. Molten metal can be removed manually with a hand scoop or an automatic scoop and a larger amount is poured into “the cold chamber” of the part to be produced. It is compressed with a plunger to fill the mould cavity.

Advantages of the Aluminium Casting Method;

Constituting an indispensable method in the production process, the Method of Casting Aluminium has the following advantages.

  • An Efficient Process: After investing in the mould, you can produce hundreds of thousands of identical parts using machining and additional labour. Particularly in the automotive industry, the Aluminium Casting Method is the answer to the problem of mass producing units.
  • Stable and Repeat Production: With the precision in die casting, you can repeat orders especially engineering parts and make high-spec products.
  • Special Finishing Operations: In line with customer requests, you can obtain parts with the desired surface roughness.
  • Flexibility of Production: In addition to the surface quality, you can carry out the production of complex-shaped parts of different cross-sectional sizes.
  • Longevity: Welding, riveting, etc. of complex-shaped parts can be produced without the need for a joining process. The production of parts in a single procedure increases the part’s strength. One other reason why parts produced in this way are durable is that they are heat resistant and dimensionally stable.
  • Low Cost: Aluminium Cast Parts are cheaper than parts made with other metal alloys.

Drawbacks of the Aluminium Casting Method;

Although it has many advantages,the drawbacks to the Aluminium Casting Method also exist. These drawbacks, that may cause an engineer or manufacturer to think again when choosing casting processes when determining their preferred production method, are as follows.

  • Casting sizes are limited. Very large pieces can not be cast.
  • The design of their moulds is difficult.
  • The investment cost of the casting machine and the associated auxiliary equipment is high.
  • The cost of mould maintenance is high.
  • The high degree of porosity in the casting complicates the heat treatment and welding processes.

Developments in Aluminium Casting

Continuous process improvements are made to increase the mechanic properties and sealing strength of the parts produced.

  • The use of vacuum systems to expel gas trapped in the mould during casting,
  • Heat treatment applications,
  • The application of a semi-solid metal process,

The improvements made to Aluminium Alloys and to the pressure treatments are ongoing, and Aluminium Die Casting applications are spreading as an alternative material in every sector.

Aluminium Alloys Used in Die Casting

Aluminium Alloys Used in Die Casting

Aluminium Alloys Used in Die Casting 1024 500 Aluminum High Pressure Die Casting | Kalkancı Aluminum Die Casting and Mold

As a consequence of the fiercely competitive nature of this new century and because we face an increase in environmental protection requirements, car manufacturers have begun developing materials as alternatives to steel and iron. While efficiency and costs are prioritised in production, vehicles that consume less fuel, and which have higher and simpler recycling combined with driving safety and comfort are produced. For these reasons, aluminium alloys have become an indispensable material for the automotive industry.

Features that lead to aluminium being the most preferred material are:

  • It is the second most widely available metal on earth
  • It is highly recyclable; it can be re-melted using only 5% of the energy required for production from its raw state
  • Aluminium alloys can be worked at high temperatures
  • Its use in the production of low weight/high strength products: aluminium is three times lighter than iron
  • It can be produced to a thickness of thin wall panels.
  • Resistant to corrosion
  • High thermal and electrical conductivity
  • Easy to shape and format
  • It is environmentally friendly: replacing every kilogram of steel with 500g of aluminium will result in ten kilograms fewer emissions over the life of the vehicle.

High-strength alloys can be formed by adding elements such as copper, silicon, zinc, magnesium, manganese, etc. to pure aluminium, which is soft and low in strength.

The classification according to alloying elements in EN standards is as follows

AlloyingFeatureAreas of use
1XXXPure aluminiumDrawn tubes (pipes), chemical equipment, foil, electrical conductors, aircraft parts
2XXXAluminium-copper alloysAircraft parts, aluminium coated sheets, cryogenic equipment, space shuttle, various tanks
3XXXAluminium-manganese alloysSheets, rigid sheets, decorative products, beverage cans
4XXXAluminium-silicon alloysAutomotive, white goods, lighting, architectural products
5XXXAluminium-magnesium alloysAutomotive, marine, cryogenic products, aircraft
6XXXAluminium-magnesium-silicon alloysAutomotive products, products manufactured by heat treatment and extrusion technology
7XXXAluminium-zinc-magnesium alloysMoulds, aircraft parts, parts where great toughness is required
8XXXLithium, iron, etc. alloys from elementsProducts which need to withstand high temperatures, electrical cables

Al-Si, Al-Mg, Al-Cu, Al-Zn alloys are widely preferred, although different alloys are prepared according to place of use and product requirements.

Material density, desired mechanical properties, melting temperatures are important factors in selecting the alloy to suit your design needs.

Aluminium Silicon Alloys

Al-Si Alloys: This type is the most commonly used aluminium alloy. When the ratio of silicon in aluminium alloys approaches 11.7%:

  • The fluidity of the liquid metal therefore its castability increases
  • Solidification resistance is reduced
  • Increases sealing under pressure
  • Reduced tendency to crack or tear during solidification
  • Hardness increases
  • The specific weight decreases
  • Thermal expansion is reduced
  • Resistance to corrosion is improved

Al-Si alloys are used in the production of welded structures, sheet production, cylinder heads, engine blocks and valve bodies.

 

Aluminium Manganese Alloys

Al-Mg Alloys : Manganese is the element that contributes to co-proportional deformation in aluminium alloys.

In aluminium alloys, when manganese rises above 0.5%, it significantly increases yield and tensile strength without reducing ductility

The addition of manganese also improves corrosion resistance and welding outcomes.

Magnesium is light in weight and has a durable structure for certain cast parts. The use of magnesium components instead of heavier aluminium components can contribute to lower fuel costs in vehicles and car manufacturers are developing new technologies to exploit the unique properties of magnesium.

But magnesium is difficult to cast because it is used at high temperatures and oxidizes quickly. It is selected for structural products, boilers and tanks, land and rail vehicles.

 

Aluminium Copper Alloys

Al-Cu Alloys: Copper is the oldest element used as an alloying element for aluminium.

Copper content in the range of 2 % – 3 % increases tensile strength and hardness at high temperatures and improves mechanical properties

Copper also improves the machinability of alloys.

But copper has a negative effect on aluminium’s ductility and corrosion resistance. During solidification its sensitivity to cracking is high.

Al-Cu alloys are especially chosen for where high strength and heat treatment is needed particularly in high-tensile parts, aircraft structural elements, fringe forged parts, heavy-duty vehicle wheels, cylinder heads and pistons.

 

Aluminium Zinc Magnesium Alloys

Al-Zn Alloys: Zinc-aluminium alloys are favoured for casting parts with narrow tolerance and thin walled cross-section parts. Like magnesium and aluminium, zinc has good corrosion resistance and dimensional stability, high strength and electrical conductivity.  Zinc alloys are generally referred to as ZAMAK in the market.

Aluminium Die Casting

Aluminium Die Casting 1920 500 Aluminum High Pressure Die Casting | Kalkancı Aluminum Die Casting and Mold

Aluminium Die Casting is a preferred casting technique with its many features. In the technique used for the application of metal castingmachines, aluminium is preferred for its corrosion resistance and great strength. At the root of this process is the fact that molten aluminiumis resilient to being poured into a metal mould under pressure. This process is executed in two different ways as follows: hot chamber die cast and cold chamber die cast. It offers a more affordable production in comparison with precision casting and metal working methods.

What is Aluminium Die Casting?

Aluminium Die Casting it is a widely used method of casting. It is one of the most utilised methods, ranking commonly after iron and steel. It is the preferred method for the production of unit aluminium parts. At a very high pressure, the copper piston pushes liquid aluminium to the mouth of the runner. The incoming liquid spreads into the aluminiumdie cast and is finally compressed. It is a technique that consists of these three stages described. A high quality alloy is used to produce Aluminium Die Casts. Consequently, all these processes take place in seconds, producing aluminium material that is resistant to wear, fatigue and high temperatures.

When applying the aluminiumdie casting method, two different metal die casting machines are used depending on the material to be produced. Cold Chamber Die Casting Machinesare generally preferred in the production of aluminium parts. Zamak Casting is the name given to the types of parts produced in Hot Chamber Die Casting Machines. Machines with a hot chamber run faster than those with a cold chamber. The method in which the plunger cylinder mechanism is installed in the crucible and the molten metal is pushed through this mechanism and injected into the mould takes place using Hot Chamber Die Casting machines. In this system, the internal structure of the casting part is near perfect, as the molten metal almost never comes into contact with air. Cold Chamber Die Casting machines use independent stove and injection systems. The molten metal bucket is automatically transmitted to the hopper. The raw material moves into the mould by means of the push of the castingpiston. The rapid nature of this castingsystem can cause air mixing and unwanted gas porosity in the casting part.

Aluminium Die Casting Companies and Their Areas of Expertise

Aluminium used in the production of aluminium die casting, though difficult to cast, is a preferred product as it is a material of great strength and lightness. Additionally, preference is given because it is easy to form, has high conductivity, and is recyclable. Aluminium die casting is suitable for casting smaller parts with complex structures.

In terms of quality controls, after the casting process aluminium is put through many tests such as X-Ray inspection, materials analysis, compression tests, smoothness test, microscope tests, CMM test, gauge/visual inspections. Each test phase is performed in order not to receive negative feedback from the customer. Used commonly in both domestic and foreign sectors, it is also used by different sectors in Istanbul. It has uses in many different sectors such as automotive, orthodontics, medical and dental devices, firearm components, hardware, lock parts, computers, electronics, and energy. It can be used either as a part, as the entire component part, or in the production of thousands of parts such as sunroofs, seating mechanisms, fuel injectors, steering columns, braces, trigger, sight, shallots, lock cylinders, etc.
