Defects in the Aluminium Die Casting Design

Die casting is a manufacturing process that involves production of geometrically complex parts using molten metal and reusable die casts. A simple and highly cost-effective process, die casting has been one of the most important reasons for the industrial revolution. In this manufacturing process, a die casting design is first created based on the size, shape and function of the final produced part. After the design is created, the non-ferrous metal perfect for the procedure will be chosen. The properties of the metal will be taken into serious consideration as it will affect the design and construction of the finished product.

As with all manufacturing processes, sometimes there may be errors and defects in the aluminium die castings, which will ultimately affect the final product. Some of the defects that could be seen in the die casting design are explained in this blog.

Bubbles

When the molten metal is poured into the cast at high pressure, there are chances for bubbles to appear in the aluminium die castings. This defect appears if the injection temperature of the metal is too high above the standard levels. Another reason is the un-uniform cooling rate of the molten metal.

If the metal is injected into the cast with a very high pressure or if the clamp pressure of the cast is too low, the molten metal will overflow and solidify outside the cast. In most cases, a thin layer of metal will solidify and cover the parting line, which will make it difficult to open the cast to release the product.

Unfilled sections

If proper care is not taken during the die casting design process, then there could be hindrances in the cast that will not allow proper flow of the molten metal. In such cases there may be unfilled sections in the cast. So, the final product will not be what is exactly required. The other reasons for the appearance of the unfilled sections include slow injection, low temperature of the molten metal when it is poured and insufficient shot volume. In all these conditions, the flow of the liquid metal is reduced, and will not completely fill all the sections of the cast.

Ejector Marks

During the aluminium die casting process, if the ejection force of the liquid metal is very high, it could create ejector marks. These defects happen because the force of the molten metal pushes out a part of the mould. So, the mould will change shape, and so will your finished product.

How is the Metal Selected for the Die casting Process?

Die casting is a process that is used for mass production of products. The process which was greatly responsible for the industrial revolution is actually very simple in terms of material and process requirements. In this manufacturing process, hot molten metal is poured into a pre designed cast. The shape of the cast is designed exactly according to the specifications of the end product. Once the molten metal is cooled, the cast is broken to release the completed product. The different metals used in die casting are magnesium, zinc, tin, aluminum and more.

The manufacturers check out many of the features of the metal before choosing the right one for the required product. A great deal of thought is put into picking the perfect zinc alloy for die casting. Slight differences in the characteristics of the alloys can give you great differences in the end products obtained. The manufacturers and cast designer consider various features of the metal before it is chosen for die casting. They will compare features such as melting point, tensile strength, yield strength, hardness, impact strength, sheer strength and more to pick the right metal alloy for the product manufacturing.

To elaborate, in zinc alloy die casting, the various alloys of this metal such as Zamak, 2, Zamak 3, Zamak 7, ZA8, EZAC, ZA 27 and other are carefully studied. The attributes are compared based on the quality of the end product. After all these background work is done, then the cast design is prepared. It is because the properties of the alloy chosen for the magnesium die casting process will determine the cast design result. The finishing properties of the metal are also carefully considered before selecting the metal alloy. If the metal has good finishing properties, then the time and effort required for post-production processes can be greatly reduced.

The manufacturers will also decide whether to cast the metal using hot chamber die casting process or cold chamber die casting process based on the metal alloy chosen. The manufacturing process needs to be tailored according to the zinc alloy decided for die casting.

The most important factor, however, is the availability of the raw material. The metal alloy should be easily available and should be in a form that is easily accessible for production. Manufacturers don’t randomly choose zinc or magnesium for die casting just because it is cheaply available or easy to get. They consider the features and functions of the end product in order to choose the best raw material.

What is Hot Chamber Die Casting?

One manufacturing technique that revolutionized the industrial world is die casting. Though this technique may sound very simple, it has been effective in reducing production expenses and increasing production count. Die casting is a process in which metal is melted in to its liquid form and then poured into the cast. The design of the cast is created based on the final product design. After the metal is poured into the cast, it is allowed to cool. The liquid metal solidifies into the particular shape. This concept is the basis for zinc alloy die casting and magnesium die casting.

There are two types of die casting used in the manufacturing world. One is hot chamber die casting and the other is cold chamber die casting. If you look at the set up for the hot chamber zinc alloy die casting, you will see the following components. It will have a gas/oil accumulator, piston, mold, casting cavity, gooseneck passage, hot chamber and toggle clamp.

First, the molten metal is filled in the cylinder. Next, a plunger forces the liquid metal in the cylinder into the die cavity through the goose neck passage. This passage allows the fluid metal to slowly start cooling. The shape, size and length of this passage will have a direct influence on the outcome of the magnesium die casting. The molten metal in the passage then flows into the cavity. A nozzle is placed at the end of the passage, so a consistent level of pressure is maintained when the liquid metal is poured into the cavity. This pressure is important for the fluid metal to completely spread inside the cavity of the cast. It also allows for uniform distribution of the molten metal. Once the mold is filled, the plunger is brought back to its original position. So, any remaining molten metal flows back into the cylinder. This prevents overfilling of the cast, which could damage the design and the final product.

This metal is allowed to cool, and the cast is broken to remove the finished product. The cooling time depends on whether you are working on zinc alloy die casting or magnesium die casting. The melting points and other properties of the metals are different, and the cast design and process will be modified to suit each type of metal. Careful planning and design will give you consistent results in hot chamber die casting process.

Reduce Fabrication Costs with Precision Castings

Product manufacturers are constantly looking for ways they can use to reduce the manufacturing casts. Precision castings offer an efficient technique to decrease expenses related to fabrication and machining. Wondering how this process can be economical in the long run?

You can save a lot of money, if you are clear about what you want when the cast design is being prepared. By incorporating many features of the tool design in the casting design, you will be able to save on a lot of extra work and resource. Discuss the design with the engineers to find ways in which the cast design can be optimized to give you better results and stronger casts. In case you want to have the logo or date on the part produced, you can incorporate it in the design itself. So, you don’t have to separately stamp the details on the product after it comes out of the cast.

The metal alloy you choose for the precision castings will also play a major role in determining your production expenses. You will have to choose the best metal alloy for the product based on the features of the element and the purpose of the finished product. If the finished product has to withstand a lot of stress and pressure, then you can choose aluminium alloy for casting. On the other hand, if the finished product has to be lightweight, then magnesium or tin alloys will be perfect for the job. Based on the metal alloy selected, you can alter the temperature, pressure and other conditions during precision castings. By determining the conditions in which the casting is done, the cast can be customized for optimum results. Also, for some metal alloys like zinc and aluminium, you don’t need to spend a lot on finishing. It is because the metal alloy itself has a good finishing, which will be reflected in the metal cast you make. So, you get maximum returns for the money you put in.

Unused casts can be recycled and used again. This is one way in which precision casting helps save you more money. If a cast has come out wrong or broke while removing from the cast, you don’t have to throw it into the bin. Again while finishing or polishing, some pieces of cast may fall. Put all the wastes in the kiln, melt the metal and reuse it again. In a production process, where there is absolutely no chance of wastage, how can one not save money?

This die casting process is efficient and economical as it saves time, effort and also decreases wastage at the same time. Different metals such as zinc, tin, magnesium and aluminium as well as their alloys are used in the die casting process.

There are small steps that you can take to further reduce aluminium die casting process expenses. The entire production process can be made less costly by making subtle changes in the die casting design.

Reduce the Weight

When you reduce the volume of components required for die casting, you can proportionately decrease the weight and cost of die casting. If you pour more metal into the cast, then it will take more time to set and cool, which will eat up into your production time. So, you can go for slight alterations in the die casting design like designing pockets to make thinner cross sections or use ribs to strengthen the cast product. Care should be taken while designing the location of the pockets because the wrong positioning of the pockets can affect the product’s accuracy and strength.

Parting Lines and Ejector Pins

While designing the aluminium die castings, careful consideration should be given to the parting lines and ejector pins. The parting line should preferably be straight or flat, so removal becomes easy. Ejector pins are used to remove the cast products from the mould. If the pins are neatly designed, then they will not leave any marks on the cast when it is removed from the mould. So, you finished product will not have any unnecessary marks and scratches which could then require another finishing touch.

Radii and Fillets

While creating the Die Casting Design, care should be taken to avoid sharp corners. If there are less sharp corners in the Aluminium Die Castings, the finished product will be stronger and have a cleaner finish. Also, there should not be quick ups and downs in the cross section, which will lead to erratic flow of molten metal in the cast, and finally lead to an irregular finish.

There are lots of the other techniques that can be used while designing the cast. These techniques will not only ensure product strength, but also reduce production time and decrease manufacturing costs.

Types of Die Casting Processes

A metal casting process used in most manufacturing processes, die casting offers an efficient and cost-effective method to produce large volumes of high-quality products. This technique is used in the manufacture of small to mid-sized metal spare parts. Die casting is basically a simple process that involves pouring molten metal into a pre-designed cast. As the metal solidifies, it moulds into the shape of the cast, which can then be easily removed from the cast and used. The important factors that determine the quality of the finished product of die casting are the raw material, temperature, solidification time and die casting process. The two popular metal alloys used for die casting are zinc alloy and aluminium. Let’s take a look at the different processes of die casting and how they affect the quality of finished product. Cold-Chamber Die Casting Process This process is commonly used for aluminium die casting. In this method, metal alloy is first melted in a furnace, and then it is manually or automatically poured into the injection system, which then passes on to the cast. It is a very slow method, which may be its only disadvantage. But, on the other hand, this technique is very effective for corrosive applications and for casting metal alloys with high melting points. Hot-Chamber Die Casting Process Also known as gooseneck casting, the hot-chamber die casting process is popularly used in most manufacturing units. It is called as gooseneck casting process because the technique involves the injected molten metal flowing through a gooseneck feed system into the cavity of the cast. This technique is best suited for metal alloys with high fluidity and low melting point. It is most commonly used for zinc metal casting, though other metals such as copper, lead and magnesium are also cast using this technique. Low-Pressure Die Casting Process This aluminium die casting technique is used when large volumes of parts have to be manufactured. In this process the mould is placed above the metal bath, and a riser tube connects the two. Pressure is applied in the chamber, which pushes the molten metal towards the cast on top. Vacuum Die Casting Process A die casting process similar to low-pressure die casting, this technique involves creating a vacuum in the cavity to force the molten metal into the riser tube and the cast placed on top. An advantage of this technique is that it prevents the formation of gas inclusions during the zinc die casting process.

Why Zinc Alloy Precision Die Casting is Suitable for Manufacturing Small Gears?

Die casting is a manufacturing process in which molten metal is poured into a cast and then cooled till it achieves the right shape. Die casting has brought about a huge change in the entire manufacturing cycle by speeding up the process and enhancing product quality. Zinc alloy die casting gives manufacturers great potential for manufacturing products in large volumes at reduced prices. Moreover with precision castings even complex shapes and designs can be created with apparent ease. The castings are also very sturdy, which enhances their performance and durability.

As with most manufacturing processes, precision die casting also greatly reduces production costs and time in the manufacturing of small gears. Using zinc alloy die casting, one can manufacture spur, helical or worm gears, all using a single type of casting. From simple to complex sizes and shapes, die casting can be used to produce almost any type of gear. It may sound impossible, but die casting makes it possible as it has the ability to bring together the unique components of all gears into one cast.

When the tool design is created, four side cores can be put together to create the worm gear cavity. The molten metal is poured into the bore at the centre, which then evenly spreads across all the tooth casts and slowly sets into the right shape. As zinc alloy has great strength even when it is made into thin walls, you can be assured of the sturdiness and durability of the finished product. The exact amount of metal required to produce the gear is used, so you will be able to reduce a lot of metal waste.

Another reason why zinc alloy die casting is an affordable option for manufacturing of small gears is that it reduces the need for the secondary finishing options. Precision castings decrease the need for secondary tasks that are generally carried out after the product is manufactured. To illustrate:

Indicator, timing marks, date, part number or other details can be carved or embossed in the casting. So when the metal is cast, the details are automatically embedded into the gear. You don’t need a separate process to mark all these details.

Also, if you need a parting line in the gear, while die casting zinc, simply mark the exact position in the mould. The parting line will accurately appear in all the gears.

There are lots of other ways in which zinc alloy die casting proves to be beneficial in the manufacture of small gears, which is why it is used in precision castings of gears.
