The information presented in this chapter is of general interest and is background information for material presented in following chapters.

In the previous information you learned general information about the die casting industry in China.  In this chapter you will learn specific information about the die casting.

The following new terms are used in this chapter.

  • Die casting “shot”      Defined as a noun in this chapter, not a verb.
  • Sprue                       Cone-shaped metal part of the shot that connects the nozzle and runner.
  • Overflows    Small pockets of metal around the perimeter of the part and also in openings.
  • Runner  The path the metal must flow through to get from the sprue or biscuit to the casting.

The Die Casting Advantage

Die casting produces components at high speed from a range of durable zinc, magnesium , and aluminum alloys while faithfully capturing the most intricate design details.

This capability makes it a prime production option for high volume production components. The ability to maintain close tolerances, often eliminating all machining, can make the process the optimum choice for lower-volume production as well.

Modern process technology that insures consistent qualityComputer control of the significant process variables has led to consistent dimensional control and internal integrity.  The process responds to statistical control and statistical problem solving techniques.
Freedom to design intricate configurationsDesign configuration is only limited to the designer’s imagination and the mold maker’s ingenuity to build the casting die.  A typical example of an intricate configuration is the automotive transmission valve body.
Net-shape casting economies, even at lower volumesElimination of machining and secondary operations can make die casting competitive at low production volumes.
Wide variety of available alloys and alloy propertiesRecall that the typical metals are alloys of aluminum, magnesium and zinc.  Small volumes of alloys made from copper and lead are also routinely die cast.  Iron and titanium materials have also been die cast.  Current alloy development includes the use of composite materials, aluminum and silicon carbide for example.
The rigidity, look and feel of metalThe perceived quality of a metal component is higher than that made from a non-metallic material. Rigidity is analogous to strength, and is based on the modulus of elasticity, and configuration.  Good rigidity also reduces vibration.
Meets moderate to high strength performanceDie cast alloy strengths are above plastics and slightly below those of sheet steels.
Moderate to high impact and dent resistanceSelected alloys have very high-energy absorption capability.
Documented fatigue strength characteristicsPublished values of fatigue strength are conservative.  High density casting processes minimize defects, such as porosity, that initiate fatigue.
Excellent sound damping propertiesStudies indicate zinc and ZA alloys are good at sound damping. Magnesium has demonstrated sound damping in drive train components.
Bearing properties that often eliminate separate bearingsZA alloys have good bearing properties.  Aluminum 390 alloy shows good wear resistance.
Inherent EMI shielding for electronic applicationsHigh conductivity provides inherent shielding
Pressure tightness for hydraulic and pneumatic componentsAlloy selection, gating technology and vacuum systems greatly reduce trapped gases and shrinkage porosity.
High quality surface finishes for decorative applicationsGood surface finish is relatively easy to achieve.  A variety of surface treatments are easy to apply.
Meets criteria for serviceability and recyclabilityAlloys are “green”, easily recycled.  The aluminum alloys are usually produced from recycled materials. The die casting alloy recycling stream is based on a worldwide metal reclamation infrastructure that has been operative for more than 50 years.

Today, with the introduction of new, higher performing die casting alloys and new process technologies, many of the old design assumptions about process limitations have become obsolete.

  • New specifications for dimensional control, draft and flatness have been issued. These specifications are reviewed and updated on a periodic basis.
  • New process enhancements including vacuum technology, squeeze casting, semi-solid casting and thixotropic molding have been developed and have led to significantly reduced levels of porosity.

The Optimum Die Casting Configuration

Before a die casting project is undertaken, the casting design should be evaluated in terms of manufacturability.  In other words, can the casting be manufactured?  Is the casting design optimum?

The optimum die casting configuration will:

  • Fill completely with metal.
  • Solidify quickly without defects.
  • Eject readily from the die.

The optimum casting configuration does not just happen.

Engineers and designers must work together to make sure the casting design fulfills the product requirements and can be manufactured.  To achieve both of these goals, the die casting must be designed with features that capitalize on the characteristics of the die casting process.  The following six principles should be used in working toward and developing the optimum die casting configuration.

Aluminum Aerospace parts

Aluminum die casting items are of remarkable use in different industry sectors and more so in the aerospace engineering where precision and top standard items is of greatest significance. These items are used in building both little as well as the big components in the aviation industry. 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.

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
  • Parts in the seat belt system
  • Components of climate control
  • Fuel system

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.

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

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.

Aluminium die casting

Capacity To Meet Your Aluminum, Magnesium, Zinc and Vacuum Die Casting Needs.

Aluminum Die Casting

Providing high-quality Aluminum die casting parts at competitive prices requires modem die casting equipment. To reduce the effects that extreme cooling temperatures have on dies CNM TECH is converting its die cooling system from water to oil. Oil maintains a warmer die temperature that contributes to a more uniform casting and extends die life, an important factor in part costs.

CNM TECH Die Casting company is adapting robotic controls to the operation of die casting machines. This permits a substantial increase in production rates, important in both controlling costs and meeting delivery requirements. It also allows us to use our people in ways which make better use of their skills and experience.

To lower production costs, CNM TECH Die Casting manufacturer has developed and patented, new, low volume, energy efficient aluminum melting furnaces. Since aluminum can be melted efficiently in small quantities, it allows the company to supply casting machines with different alloys of aluminum simultaneously. Casting machines don’t have to stand to wait for a large furnace to supply the proper alloy. Schedules aren’t built around what alloy is in the furnace.

Zinc Die Casting

For applications where high impact strength, low cost anZinc Die Castingd close dimensional limits are important design considerations, zinc die casting plays an important role. Zinc normally permits higher production rates than aluminum and parts can be designed with thinner cross-sections. The resulting parts are highly resistant to corrosion and receptive to a variety of beautiful finishes.

High rates of production and uniform quality are maintained by die casting machines with automatic extractors.

Vacuum Die Casting

Vacuum die casting is preferred by many casting buyers because it results in a less porous part. CNM TECH’s Vert-a-Cast machines, with a clamping force of 400 tons, are capable of producing castings automatically at a much faster pace than manually-operated horizontal machines.

Vacuum die casting, a CNM TECH capability for ten years, is often the only economical way to meet critical porosity specifications.

Maintenance, repair, changes and corrections on dies are accomplished promptly in CNM TECH’s fully-equipped tool and die shop.

Alloy materials are melted, fluxed and cleaned in the central furnace before being transferred to die casting equipment.

Metal casting services involve the shaping of free-flowing liquid metals through the use of dies, molds, or patterns.  Castings are generally roughly finished due to the nature of their production.  In many cases, additional finishing is required to remove burrs and other artefacts of the casting process.  Metal castings services are used to design a wide range of components and finished products.  Everything from simple nails and fasteners to engine blocks can be fabricated using metal casting services.  Common metal casting processes include sand casting, die casting, permanent mold casting, investment casting, centrifugal casting, and lost foam casting.

Sand Casting

Sand casting is used to make large parts (typically iron, but also bronze, brass, aluminum). Molten metal is poured into a mold cavity formed out of sand (natural or synthetic). Sand castings generally have a rough surface, sometimes with surface impurities and surface variations.

zinc Die Casting

zinc Die Casting

Die-casting includes a number of processes in which reusable dies or molds are used to produce casting.  The die contains an impression of the finished product together with it’s running, feeding and venting systems.  The die is capable of a regular cycle and of (quickly) dissipating the heat of the metal poured into it.  Once the liquid metal has cooled sufficiently, the mold is opened and the casting can be removed and finished.

Permanent Mold Casting

In permanent mold casting, molten metal is poured into cast iron molds, coated with a ceramic mold wash. Cores can be a metal, sand, sand shell, or other materials. When completed, the molds are opened and the castings are ejected.


Investment casting services involve molding patterns by the injection of a special wax into a metal die.  The patterns are assembled into a cluster around a wax runner system. The ‘tree’ of patterns is then coated with 8-10 layers of refractory material. The assembly is heated to remove the wax.  The hot mold is cast, and when cool, the mold material is removed by impact, vibration, grit blasting, high-pressure water blasting or chemical dissolution leaving the castings, which are then removed from the runner system.

Centrifugal casting

Centrifugal casting services are used to produce castings that are cylindrical in shape.  In centrifugal casting, a permanent mold is rotated about its axis at high speeds as the molten metal is poured. The molten metal is centrifugally thrown towards the inside mold wall, where it solidifies. The casting is usually a fine grain casting with a very fine-grained outer diameter, which is resistant to atmospheric corrosion, a typical need with pipes. The inside diameter has more impurities and inclusions, which can be machined away.

magnesium die casting

magnesium die casting

Lost foam casting

Lost foam casting (LFC) is metal casting services that use foam filled patterns to produce castings.  Foam is injected into a pattern, filling all areas, leaving no cavities.  When molten metal is injected into the pattern, the foam is burned off allowing the casting to take shape.

Die casting

Die casting and metal casting includes a number of processes in which reusable dies or molds are used to produce casting. The die is capable of a regular cycle and of (quickly) dissipating the heat of the metal poured into it. Once the liquid metal has cooled sufficiently, the mold or is opened and the casting can be removed and finished.

Once the liquid metal has cooled sufficiently, the mold or is opened and the metal casting can be removed and finished.

high pressure die casting

The high pressure die casting process is the most widely used, representing about 50% of all light alloy casting production. Low pressure die casting currently accounts for about 20% of production and its use is increasing. Gravity die casting accounts for the rest, with the exception of a small but growing contribution from the recently introduced vacuum die casting and squeeze casting process. the design of low pressure and gravity die casting dies for improved die filling, optimized solidification pattern and maximum yield. Gravity die-casting is suitable for mass production and for fully mechanized casting. Low-pressure die casting is especially suited to

High pressure die casting process

In this process, the liquid metal is injected at high speed and high pressure into a metal mold. A schematic view of high pressure die casting is given in Figure.

This equipment consists of two vertical plates on which bolsters are located which hold the die halves. One plate is fixed and the other can move so that the die can be opened and closed. A measured amount of metal is poured into the shot sleeve and then introduced into the mould cavity using a hydraulically-driven piston. Once the metal has solidified, the die is opened and the casting removed. Compared to Gravity die casting, both the machine and its dies are very expensive, and for this reason, high pressure die casting is economical only for high-volume production.

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.
