Aluminum Die Casting: The Ultimate FAQ Guide

In today’s guide, I will answer all your questions on aluminum die casting.

To be precise, this guide will help you become an expert in aluminum die casting industry.

Let’s get started:

What Is Aluminum Die Casting?

It is a metal-casting process for making relatively complex aluminum parts.

The entire process involves heating aluminum ingots to extremely high temperatures until they become entirely molten.

In the molten state, the liquid is injected under high pressure into a mold.

It solidifies to form a smooth surface, which hardly requires a machining process.

You can repeat the process severally using the mold before it deteriorates, thus an ideal technique for mass production of aluminum components.

What Are The Advantages Of Aluminum Die Casting?

Die casting offers several advantages over other available metal-forming processes such as the following;

  1. Allows you to produce comparatively complex shapes, which are not easily attainable when you use extrusion or machining methods.Moreover, it allows you to attain smooth surfaces consistently and gives capacity to accommodate large and small parts.
  2. It is the most affordable technique for producing different aluminum parts in mass volume.
  3. The aluminum parts it produces are generally hardy, exhibit incredible dimensional stability, and visually attractive.
  4. Aluminum die-casting creates lightweight parts and offers more surface finishing options.

Which Are The Different Aluminum Die Casting Tooling Available?

They are quite several, but the main tooling options used widely include the following;

Multi-Slide Die Casting

This process uses four perpendicular slides in the tool to allow for production of more accurate and complex castings.

There are some occasions where the process can use up to about six slides at different angles other than 90°.

The advantage of multi-slide die casting is that it offers consistent part quality.

It also lowers tooling costs, provides rapid cycle speeds, and eliminates need for secondary operations.

Hot Chamber Die Casting

This tooling process involves use of different alloys with relatively low melting temperatures.

Essentially, in this die casting process, metal is heated inside the casting machine instead of a different furnace to attain the molten state.

A hydraulic-powered piston is used to force molten metal out of the furnace and into the die.

It is relatively fast and often lasts for a typical cycle that would last for about 15-20 minutes.

Cold Chamber Die Casting

In this die casting process, metal is heated in a separate furnace then molten metal is transferred to mold cavity.

The molten material is forced into the mold cavity by a pressurized plunger.

What Is The Difference Between Conventional Hot Chamber Die Casting And Multi-Slide Dies Casting?

Conventional hot chamber die casting process is a tooling method, which comes in one part per cycle or multiple parts per cycle.

The tool’s design in conventional chamber dies casting is relatively efficient and often eliminates the need for secondary operations.

It is a suitable method for managing volume production and produces relatively durable tools.

On the other hand, multi-slide die casting uses at least four perpendicular slides in the tool.

This allows for creation of more complex and accurate castings.

Multi-slide die casting produces minimum part-to-part variation and offers tooling, which is less susceptible to parting line variation.

Which Are Die Casting Techniques Applied In Aluminum Die Casting Process?

Often, there are two main techniques used in the aluminum die casting process, and they include the following;

Die casting process

Die casting process

Low-Pressure Injection

This technique involves use of air pressure to force molten aluminum material upwards into a closed die cavity.

It is a suitable aluminum die casting process for creating circular part designs and pressure-tight vessels.

High-Pressure Casting

This process involves injection of molten aluminum into mold or die casting machine under force by using a significant pressure to create form products.

It produces excellent dimensional accuracy and smooth surfaces; thus, the parts hardly require machining.

This technique is fast and more affordable than other casting processes.

How Does Hot Chamber Aluminum Die Casting Process Vs. Cold Chamber Aluminum Die Casting Process Compare?

Hot chamber vs cold chamber die casting

Hot chamber vs cold chamber die casting

In hot chamber aluminum die casting, the injection mechanism is immersed in the molten metal.

The furnace is attached to the machine by a specific metal feed system often referred to as gooseneck.

When the die closes, the piston rises, opens the port, and allowing the molten material to fill up the cylinder.

What follows is the plunger seals the port and pushes the molten metal through nozzle and gooseneck into die cavity.

The die opens, cores retract, and casting stays in one die half of the ejector side.

Ejector pins force casting out of ejector dies. Metal flows through inlet to refill the gooseneck once the plunger uncovers the filling hole.

On the other hand, in cold chamber die casting process, the molten material is ladled from a crucible into a short-sleeve.

This is where a plunger that is hydraulically operated forces the molten metal into the die.

The excess material is used to push additional metal into the die cavity to compensate for shrinkage occurring during solidification.

Contrary to hot chamber die casting, cold chamber deals with corrosion issues by separating melt pot from injector parts.

What Are The Components Of Hot Chamber Aluminum Die Casting Machine?

A typical hot chamber die casting machine is made of several parts and components, which include the following;

  • Piston
  • Gooseneck
  • Die
  • Toggle clamp
  • Plunger
  • Ejector pin

How Do You Perform The Aluminum Die Casting Process?

In this process, the die is created in at least two sections to ease casting removal.

The casting cycle begins with clamping of two-die halves tightly by the die casting press.

What follows is injection of molten aluminum into the die cavity, where it solidifies relatively fast.

The sections are mounted tightly in a machine and assembled such that one stays stationary and the other remains moveable.

Ejection of casting takes place once the die halves are drawn apart.

The specific die casting can be simple or complex based on the simplicity or complexity of the casting.

They can also have moveable cores, slides, or other sections depending on nature of casting.

To attain the locking, most machines use mechanisms actuated by hydraulic cylinders, whereas others use direct-acting hydraulic pressure.

Die casting machines, whether small or large, come in handy only when injecting molten metal into the die.

What Are The Key Considerations During Aluminum Die Casting Part Design?

Aluminum die cast components

Aluminum die cast components

It is fundamental to consider a few core elements when designing a part to be cast.

Some of these factors include the following;

The mold design should enable it to separate and allow the solidified aluminum to come out easily.

Parting line, which is the mark where two mold halves come apart, should be considered in early stages of die part design.

The other vital consideration to have in mind is thickness of part walls. Technically, there is no restriction to minimum wall thickness.

However, it is essential to develop parts with uniform thickness.

Injection points’ location is another fundamental consideration in aluminum die casting part design.

An ideal way of attaining this is by surrounding the points using aluminum and still allow the part to come off when mold is separated.

Which One Should You Use In Aluminum Die Casting: Primary Aluminum Or Secondary Aluminum?

Ideally, there is marginal functional difference between primary and secondary aluminum as far as to die casting is concerned.

However, it is more economical to produce secondary aluminum than primary aluminum.

Essentially, it needs about 5% as much energy to produce, making it a relatively cost-effective option.

In a typical aluminum die casting process, a higher percentage of energy consumption is used in heating and re-melting the material.

Therefore, using secondary aluminum gives value for money hence a better choice to consider in aluminum die casting.

How Do You Minimize Aluminum Die Casting Part Porosity?

It starts with early planning when designing die-cast parts and communication with our engineering.

In such instances, it becomes easier to outline whether porosity in specific areas shall be detrimental to product function by outlining design begins.

Acceptable modifications in part designs are also fundamental to suggest in a bid to reduce possible porosity issues.

After undertaking this step, we can utilize mold flow simulation.

It can also optimize gating, overflow design, and complex process control and monitoring to restrict porosity to non-critical spots of the part.

What Are The Components Of Die Construction In Aluminum Die Casting?

They include the following;

  • Die sets, shoes, and plates
  • Bushings and guide pins
  • Heel plates and heel blocks
  • Pads
  • Dowels, keys, and screws
  • Spools and shoulder bolts
  • Retainers
  • Punch holder
  • Bolster plate
  • Stripper plate

Which Are The Different Ways Of Activating Cores Slides In The Aluminum Die Casting Die?

Core slides are also referred to as moving die components.

Ideally, they can be activated using several methods, but the most common ones include the following;

Angle Pins

This refers to a mechanical source of motion often activate by closing and opening of the die.

Angle pin method hardly requires limit switches or hydraulics. Besides, it is relatively economical to manufacture.

However, it does not have control over the cycle of slide pull.

Hydraulic Cylinders

It is a technique of slide motion, which allows selection of cycles and placement of slides on any side of the die.

This is vital since it avoids interference when removing the casting from the particular die.

Whether to use it or not is dependent on numerous factors such as die size, production volume, and specific part configuration among others.

How Many Types Of Dies Are Used In The Production Of Aluminum Die Casting Parts?

They usually come in four major types such as follows;

  1. Single cavity for producing one component
  2. Multiple cavities for producing several identical components
  3. Unit die for production of different parts simultaneously
  4. Combination die for production of numerous different parts for an assembly.

Thus, when the molten metal is injected into the die, the material cools and becomes solid faster.

In other words, the time it takes while in a molten state before it changes into a solid state is relatively short.

It, therefore, implies that for a thin wall part of 0.5-1mm to form, it requires less than 30 milliseconds.

Thus, it requires meticulous precision to make a thin-walled aluminum die casting part.

What Are The Advantages Of Thin-Walled Aluminum Die Casting?

  1. It forms lightweight parts, which is vital in tooling industry since it makes it easy to handle the part in different applications.
  2. Mostly, thin-walled parts tend to create a wide range of surface finishing options.
  3. Increases versatility since you can easily use it in different applications where surface thickness is a concern.
  4. Thin-walled aluminum parts retain high dimensional stability, which is a vital feature in many applications.

How Does Squeeze Casting And Semi-Solid Molding Compare In Aluminum Die Casting Process?

Squeeze casting involves casting molten metal without any gas turbulence or entrapment under high pressure to attain quality, dense and treatable material components.

Semi-solid molding, on the other hand, entails casting the metal billets to produce heat treatable aluminum castings with low consistency.

Are Aluminum Die Casting Parts Corrosion Resistant?

Yes.

Aluminum alloy can withstand harsh conditions lasts longer than other alloy materials as far as corrosion resistance is concerned.

Essentially, aluminum die casting part has the natural ability to “heal” itself over a period even when the exterior part is corroded.

Is Machining Of Aluminum Die Casting Part Possible?

Yes.

Aluminum die casting parts can be machined from billet or sheet stock using CNC machining process.

This machining method is faster and offers incredible precision, thus ideal for aluminum parts.

What Are The Post-Casting Operations In Aluminum Die Casting Process?

Some of the most common operations include:

CNC Precision Machining

It is often used when the unit machining trade-off is cheaper than investing in complex automated die casting die slides to attain net-shape components.

However, it requires a higher level of experience in CNC pre-planning and metal machining center fixture design to attain best results.

Surface Treatments And Finishing

Several surface treatments and finishing are used on aluminum die casting parts.

The essence is to provide a decorative finish, coating against galvanic corrosion, achieve pressure tightness and enhance part’s resistance to wear, etc.

There are many finishing operations such as powder coating, anodizing, polishing, painting and chrome plating, amongst others.

Do The Features Of Aluminum Die Casting Part Affect The Surface Finishing?

  10. Print a note containing all relevant part specs for casting process and other important information. It is vital in ensuring production repeatability and reducing inspection time.

Are There Alternatives To Aluminum Die Casting?

Yes.

Sand Casting

It is an ideal method you may consider as an alternative for producing different aluminum parts.

Sand casting involves using a pattern, which is a replica of the finished casting.

You can press any pattern into a fine sand mixture to create mold where the molten aluminum is poured.

Even so, the pattern formed by sand casting is marginally larger than the actual part to be made.

Of course, this allows aluminum to shrink during solidification and cooling.

Nevertheless, sand casting is relatively slow than die permanent mold casting, but it is cost-effective for small-scale production.

It is also an ideal alternative for making complex designs or when you need large casting.

Investment Casting

In some instances, it is known as precision casting or lost wax casting.

This method creates parts from molten aluminum metal.

Ideally, it involves forming a wax pattern to resemble the shape of desired final product.

The wax shape is then attached to a tool repeatedly dipped in liquid ceramic until it hardens.

Molten aluminum hardens within a mold before it is shattered, creating a whole cast metal part.

This process is an ideal aluminum casting alternative for lower volume production. In essence, its part prices tend to be higher than ordinary die casting techniques.

What Are The Important Tolerance Guidelines For Aluminum Die Casting Process?

The design engineer must understand the needed precision dimensions for each feature of a part is hardly possible in production.

Precision tolerances should be specified in agreed-upon crucial areas

Consultation with the design engineering in final part design stage is crucial in determining affordable production and part quality assurance.

Which Are The Various Techniques Of Prototyping Aluminum Die Casting Design?

  • 3D printing – This technology allows for the production of rapid prototypes in sturdy ABS plastic materials directly from STL design files.
  • Machined Prototype – It produces parts to almost identical part weights and indicated die casting tolerances with accurate details.
  • Gravity Cast Prototype – This technique needs thicker walls and comparatively large tolerances.
  • Die Cast Prototype – It is the most appropriate approach to undertake if you want to attain exact specifications and geometry to be in place during production.
