What is Aluminum Die Casting?

Aluminum Die Casting is a widely used metalworking process for producing metal parts with great accuracy and durability. It is one of the most common production methods used by manufacturers all over the world.

Aluminum Die casting is mostly done in a cold chamber machine. The parts are made by injecting fluid aluminum into a die casting mold under high pressure using a plunger. However, there are several steps involved before and after casting the parts.

In order to ensure the highest quality for your parts, it is necessary to execute all the steps involved in mold castings with proper quality control. It is where an experienced and inexperienced manufacturer can play a big role in your project.

Why Should I Choose Aluminum Die Casting?

There are various facts that make aluminum die casting an excellent solution for your products. Let’s have a look at its multitudes of benefits that can greatly enhance your experience with the manufacturing industry.

It’s Economical

Aluminum is the third most abundant element and the most abundant metal on earth. About eight percent of the earth’s crust consists of aluminum. Due to the abundance in nature, aluminum is very cheap and available all over the world.

Due to the low cost of raw material, aluminum has become extremely popular in the metalworking industry in a relatively short period.

Lightweight Parts

Aluminum is almost three times lighter than cast iron. This fact alone has been a major driver for preferring aluminum parts. Now developers can make fuel-efficient vehicles. The use of metal in portable goods also became a common scenario as well.

The aerospace industry, in particular, has shown more interest in aluminum die cast parts. Its excellent strength-to-weight ratio makes it the ideal material for this job.

Corrosion Resistance and Wear Resistance

Aluminum die cast parts have exceptional protection against corrosion. It has good wear resistance too. So they are suitable for the corrosive environment and heavy loading conditions. It also minimizes the need for costly surface protection measures.

Increases Production Capacity

Modern die casting methods have made the production of huge volume parts easier than ever. It can produce more parts at a particular time frame when compared against other methods of metalworking. So, it can significantly shorten the project lead time and increase your production capacity.

Enhanced Conductive Properties

Aluminum die castings offer great electrical and thermal conductivity. Aluminum parts exhibit exceptional heat dissipation characteristics, RMI-EFI shielding properties. So, they are extensively used for heat sinks, enclosures of many consumer electronic products.

Why Should I look for an Aluminum Die Casting Supplier Instead of a Zinc or Magnesium Die Casting Supplier?

Aluminum is a more commonly used cast metal for production compared to other non-ferrous metals such as zinc and magnesium. Here I have explained the features of zinc and magnesium die casting to help you decide when aluminum might be a better choice.

Zinc has material properties similar to that of aluminum. It has excellent strength, corrosion, and wear resistance. The raw material cost of zinc is almost equal to that of aluminum. It has a lower melting temperature and easier to cast than aluminum.

But zinc is several times heavier than aluminum. And zinc die casting parts can’t retain strength under high temperatures. So, even with some benefits, zinc is a less preferable option for production. However, zinc is used for producing small parts with intricate details.

Magnesium alloy products are lighter than aluminum, which is a desirable feature for any product. Magnesium parts have excellent machinability as well. But magnesium die casting manufacturers face some production difficulties.

First of all, magnesium parts are costlier than both zinc and aluminum. They are lightweight but tend to buckle under heavy loads. Magnesium is very susceptible to corrosion and wear as well. So, expensive coatings are required for magnesium die-cast parts.

Although there are some special applications for magnesium die cast products in aircraft and sports equipment. But, the slight reduction in weight accompanied by significantly higher production cost and durability issues is not something most preferable by a die casting company.

What are the Technologies Used by Aluminum Die Casting Manufacturer?

There are different aluminum die casting technologies available. Each has its pros and cons. And not all of them are suitable for every task. Different die casting machines may offer better precision, faster production, or support casting of specific materials.

Some of the common aluminum die casting technologies are,

1. Low-Pressure die casting
2. High-Pressure die casting (Cold Chamber)
3. Semi-solid die casting
4. Vacuum die casting
5. Squeeze die casting

Low-Pressure Die Casting

Porosity is an annoying issue for any die-cast parts. Low pressure die casting is a way of making aluminum parts with reduced porosity. Low-pressure die casting applies additional pressure during the casting. It allows more compact and defect-free parts

But its use is rather limited due to its slower casting cycle, which hampers the production capacity. So, most of the aluminum die casting vendors focus on its faster alternative, the high-pressure die casting.

High-Pressure Die Casting (Cold Chamber)

When you demand high-quality parts and need them fast, high-pressure die casting is what you are looking for. It is more like a standard for aluminum die casting all over the world. That’s why mainly focused on this method in the rest of the guide.

However, there are two high-pressure casting processes, namely the hot-chamber and cold-chamber process. Aluminum has a high melting point. Due to this, it needs to die cast in a separate furnace and carry into the machine with a cold chamber setup.

Semi-solid Die Casting

This aluminum die casting method handles metals that are in between a state of solid and liquid. Metals with such fluidity are called thixotropic fluids. This state of the metal is commonly known as semi-solid. It allows casting aluminum with higher precision.

The semi-solid casting procedure is used for making parts that have delicate applications. Mainly aircraft, medical devices, defense equipment, etc. are produced using the semi-solid die casting method.

Vacuum Die Casting

Vacuum die casting is an improved process. A pressure die casting equipment is often equipped with a vacuum mechanism to deal with the gas pores trapped inside a mold.

That’s why it is also known as vacuum-assisted high-pressure die casting too. It significantly minimizes casting defects involved during die casting and helps to reduce wastage.

Squeeze Die Casting

It is a simpler form of the high-pressure die casting process. It is often a cheaper alternative for making certain types of parts. It works by pouring a preheated die with molten aluminum and pressing it with another die to form the casting.

Squeeze die casting’s capabilities are rather limited. The casting cycle is usually slower than other methods.

What are Your Material Options for Aluminum Die Casting?

The aluminum alloy used for casting is different from those used in machining or forging. Casting requires the materials to have good fluidity. Aluminum is alloyed with some elements to increase its fluidity properties and make it more suitable for die casting.

Some of the aluminum alloys we recommend and use ourselves are,

1. A380
2. ADC12
3. AlSi10
4. AlSi9Cu3 etc.

There are many other aluminum alloys available in the market too. You are welcome if you want us to use a particular alloy. We shall assess its suitability and arrange it for you if possible.

How Can Your Company Reduce the Aluminum Die Casting Cost?

A significant cost associated with aluminum die casting is due to the high tooling cost. Because die casting tooling is done using CNC Machines. And CNC machining can be pretty expensive based on the complexity of the parts you are producing.

Certain design tips can greatly reduce machining time and cost for you. Some of them are discussed below.

Maintain Adequate Draft Angle

Draft Angle is the vertical inclination of outer walls along the parting line. It is provided to allow easier removal of casting from the die. You can see a similar feature in cupcakes as well. They have a larger diameter at the top and a smaller diameter on the bottom.

Keep Undercuts Minimum

Avoid undercuts in your custom designed casting parts. If your product must include some undercuts, at least keep them aligned with the parting line. If undercuts are not appropriately placed, they complicate the casting process. Thus make it too expensive or impossible to cast.

Avoid Sharp Edges

Any sharp edges in your dies make both machining and casting difficult. Machining sharp edges require CNC machines with high accuracy, which are also more expensive. And sharp edges in dies makes it difficult to remove a casting and often damage the edges.

Avoid Intricate Features

The tooling cost will drastically increase with the rise in complexity. Keep your design simple, and avoid unnecessary details. Try not to keep any deep pockets and avoid thick walls in your designs. Maintaining a uniform wall thickness is advised as well.

Following these guidelines can significantly simplify the machining process and reduce the production cost of aluminum die casting.

Why Aluminum Die Casting Process is Most Popular in China?

Compared with aluminum die casting manufacturer in India, China has the largest share in the production industry. And Chinese manufacturers are racing against each other to develop cost-effective and efficient production methods. High pressure die casting is by far the most widely used die casting technology in China.

As we stepped into the modern era, our demand for high-quality products kept on increasing. In order to meet the growing demand of end-users and manufacturers need a faster and economical production approach.

With so many die casting companies available right now, assurance of the highest quality is of prime importance. High-pressure die casting is the most viable process for the mass production of aluminum parts. Some manufacturers are also adopting vacuum-assisted machines for better quality.

We maintain optimum quality control in all stages of production. The complete quality control process of Sunrise Metal is explained below.

Inspection of Raw Material

The incoming raw material properties are thoroughly tested with the help of a spectrometer. It helps us verify the raw material specifications by identifying the parameters such as,

• Grade of the Alloy
• Chemical Composition
• Purity, etc.

No matter how good quality control measures are in motion in the later stages of production, optimum structural integrity and performance can’t be achieved without good raw material.

FAI and LAI for Die Casting

Many suppliers will only conduct an FAI for die casting. But Sunrise Metal runs both First Article Inspection (FAI) and Last Article Inspection (LAI) during the manufacturing process. The FAI allows us to verify whether or not the manufactured part can meet your requirement.

But sometimes the die casting setup may deter from the initial condition. So, we carry out LAI and do random sampling of parts every two hours to ensure that the quality remains the same for the entire batch of parts.

Optimization and Inspection of the Machining Process

Proper assessment of the parts is needed to ensure its manufacturability. Certain geometric features in a design can make it impossible or very difficult to machine. We provide effective design for manufacturing to avoid such issues.

We simulate the whole machining process beforehand to minimize the chances of errors during production. We also inspect the completed parts using CMM to measure the dimensions.

Surface Treatment Quality Inspection

The surface finishing provided to the parts is inspected using multiple inspection equipment. The color of the parts is assessed with a color meter. Thickness testing machines are used to verify the uniformity of coating thickness. We also have salt spray testers to assess the durability of the surface finishing.

Outgoing Inspection

The finished parts are given a final check before they leave our premises. Performance and reliability assessment of the parts is carried out to ensure that the parts meet the specifications required by the customer.

Finally, the parts are given identification marks for ease of traceability. So, we can deal with product quality issues if any arises during usage. It allows us to deal with defective products faster and creates scope to enhance and predict quality for future production.

What Kind of Quality Control Instruments are Used at Sunrise Metal?

Sunrise Metal has dedicated instruments to ensure the optimum quality of any machined or cast parts along with the surface finishing. Some of the fundamental types of instruments available at Sunrise Metal are as follows.

Dimension Measuring Instruments

Coordinate Measuring Machine (CMM): CMM’s can accurately measure any geometric features by sensing discrete points on its surface with a probe. We have the leading-edge Zeiss Contura G2 CMM from the widely renowned Carl Zeiss brand at your service.

It allows us to take high-speed measurements with excellent accuracy. It also has an automatic scanning function. Its flexibility promotes better quality control of complex casting parts. Here’s a video of our employee operating the Zeiss CMM.

Caliper: We have calipers for taking measurements of standard tolerances. This allows us to take quick measurements that involve less time and labor.

Integrity Assessment Instruments

X-ray Detector: We can identify any internal defects present in the casting parts with the X-ray detector. It allows us to deal with critical issues like cracks and porosity. So, we can maintain optimum quality control and ensure maximum structural integrity.

Spectrometer: We can measure the spectral elements to verify the chemical composition of raw material and casting parts. This we can confirm the structural integrity of parts.

Hardness Testing Machine: It is a very useful instrument for measuring the mechanical strength of parts. So, we can ensure that our parts meet your required specifications.

Surface Finishing Testing Devices

Salt Spray Testing Equipment: We use this instrument for getting a relative measure of the corrosion resistance of surface finishes. It allows us to provide an estimation of the durability.

Thickness Testing Machine: We use a non-evasive testing device to check the thickness of the surface finishing. And we ensure that there are no irregularities in the parts.

There are many other quality control instruments available here as well such as,

• Color Meter
• Microscope
• Leakage Test Equipment
• Cleanliness Test Equipment
• Projector, etc.

These help us assess the different physical and mechanical properties of the casting parts and the quality of the surface finishing.

How Does Sunrise Control the Part’s Traceability?

Traceability is a prerequisite for the quality management system of any company. It is a company’s ability to uniquely identify and track all processes from raw material collection to production, supply, sales, and consumption of their manufactured goods.

It allows the manufacturer to trace a part back to its origin from any stage of the production or distribution process. So, the company can acknowledge valid claims to recall their products in case the consumer encounters a defective product.

This helps build trust for a company as the consumer is aware of the source and quality control measures involved in manufacturing. It also increases the transparency and credibility of warranty terms of a part.

So, Sunrise metal values part’s traceability and treats it as an inherent element of the quality management system. We ensure proper traceability of parts through the following procedures.

Assign Batch Control Card

We have a Batch Control Card for every batch of production. All traceability parameters of that particular batch are recorded in the card. It allows us to keep track of important things such as,

• Time of production
• Shift leader in charge
• Operators working on that batch
• Production quantity, etc.

Lettering and Labeling of Individual Parts

Being able to uniquely identify each part is also important. So, we provide the parts with a unique identification number. For tracing die casting parts, we usually include lettering in the mold. We ensure traceability through labeling, printing, and laser etching as well.

The following details are usually included for traceability,

• An ID no. for each part
• Work details
• Part dimension
• Inspection results, etc.

Is Sunrise Metal a Continually Improved Company?
