In this stage, you need to spray a lubricant within the die cavity.

The lubricant assists in controlling the temperature level of the mold.

Also, it will enable the easy removal of the magnesium cast before closing the mold.

Step 2: Filling

Here, you will fill the molten magnesium metal in a mold at high pressures.

The pressure range can vary between 10 MPa to 175 MPa.

After filling the molten magnesium metal, you will maintain the pressure level until the magnesium cast solidifies.

Step 3: Injection

Here, you will open the die and then eject the shots using ejector pins.

The shots vary from one casting to another since they may have several cavities within the die.

This feature allows you to make several castings for every shot.

Step 4: Shake Out

This process entails the separation of the scraps.

These include rubbers, flash, gates, and spures.

Shake out process happens through the extrusion of the casting via specialized dressing dies.

Alternative sand falling techniques entail grinding and sawing.

Step 5: Defect Inspection

Once you complete the shake-out stage, you can check for any defects on the magnesium cast.

Some of the common types of defects include cold heading and stagnation.

Besides, hot-chamber magnesium die casting has a short casting duration that lasts about 1 second.

Also, it is costly to maintain this version than to maintain the cold chamber version.

Illustration Of Hot Chamber magnesium Die Casting

 Illustration Of Hot Chamber Magnesium Die Casting

The hot-chamber magnesium die casting entails the following:

  1. The plunger moves upwards thus enabling the molten metal to fill the cylindrical void
  2. After that, you will close the die
  3. The plunger moves downwards forcing the molten metal via a gooseneck to the cavity die
  4. Afterward, you will hold the plunger under pressure until the metal solidifies once you fill the die
  5. Open the die and the magnesium cast will remain in the die that contains ejectors
  6. The plunger moves upwards and the surplus molten metal moves through the gooseneck to the holding vessel
  7. Ejectors will push the magnesium die cast out from the die

Cold Chamber Magnesium Die Casting

Here, the temperature of the chamber where you will introduce the molten metal is cold.

The chamber is maintained at room temperature before introducing the molten metal.

Here is the process of cold chamber magnesium die casting:

  1. Start by filling the pressure chamber with molten magnesium metal
  2. Force the plunger to move forward to increase the pressure that will make the molten metal flow via the spruce
  3. The molten metal moves via the spruce to the cavity
  4. Once the metal cools and solidifies, the plunger will retract to the original position
  5. This allows you to get ready for filling fresh molten metal within the cavity
  6. The die will open and the ejector pins will remove the magnesium die cast from the die
  7. The magnesium die casting process can now be repeated

 Illustration Of The Cold Chamber Magnesium Die Casting

Components Of Cold Chamber Die casting

What Are Some Variations Of Magnesium Die Casting?

These variations are meant to overcome any errors, flaws, or other problems that you may encounter in a magnesium die casting.

The variants include:

Pore Free

Here, you will fill the die cavity with oxygen before pouring the molten magnesium metal.

The oxygen will combine with the metal chemically hence preventing the formation of gas pores within the casting.


This variation will combine a stable fill and a directional solidification process to form rapid cycle times.

It entails the following:

  1. Heat treatable casting
  2. Thermal analysis
  3. Indirect squeezing


Here, you will pour and fill molten magnesium metal in a permanent die.

The parts are stiff, high quality, strong, and with good mechanical traits.


This is a labor-intensive method that shapes the mold from a wax template that you will dip in a ceramic liquid substance.

Besides, you will pour molten metal into the ceramic cavity once the ceramic hardens and the wax melts off.


Here, you will swirl, pour, then send the slurry molten metal to a shot sleeve.

Then you will force it using pressure to go within a die cavity.

Vacuum-assisted High Pressure

Here, you will place the die in an airtight system.

Afterward, you will create pressure to draw the molten metal where you will eject it after solidification.

Low Pressure

Here, the chamber is below the magnesium die which will push upwards via an inlet port to the die chamber.

Also, you will maintain pressure until it will solidify.

What Types Of Dies Can You Use In Magnesium Die Casting?

A die caster will use different dies to cast numerous components containing various features and characteristics.

The types of dies you can use include the following:

Single Cavity

This type has one cavity and can therefore form one cast per unit time.

Also, you will use a single cavity die when the die-cast equipment can make single cavity dies.

Besides, it will address the following:

  1. Locking force
  2. Shot height
  3. Dimension of the die

Single cavity dies are suitable in scenarios where the production capacity is low.

Also, this process is suitable for making parts that require center gating and complex parts requiring multidirectional side cores.

Multiple Cavity

These dies use more than one cavity to produce identical components.

Besides, they are suitable for the following:

  1. When there is a need to produce more magnesium die casting per unit time
  2. Economically feasible when considering the cost of purchasing the equipment and making the magnesium die cast
  3. When the machine can accommodate dies with several cavities

Combination Die

These dies have several cavities and can make several parts as opposed to multiple cavity die.

Combination dies are suitable when you need to lower the magnesium die casting costs.

Unit Die

These are small independent dies that you can insert within a main holding die, which is fixed.

Besides, you can alter the unit dies to make various magnesium die casting parts.

A majority of unit dies are single cavity dies.

How Does Magnesium Die Casting Compare To Aluminum Die Casting?

Aluminum die casting alloys happen within a cold chamber while magnesium die casting alloys happen in hot chamber equipment.

The magnesium alloy components are lightweight than the aluminum die casting components.

Also, the cost of performing aluminum die casting is less than that of magnesium die casting.

The casting cycle duration of aluminum die casting is lower than that of magnesium die casting.

Magnesium die casting has lower stability than aluminum die casting.

Besides, the magnesium die casts are easy to machine.

Magnesium die casting can form thinner walls than aluminum die casting.

Aluminum die casting has a better corrosion resistance than magnesium die casting.

Both the magnesium and aluminum die casting employ a high-pressure casting process.

Also, both of these processes are non-ferrous and are sturdier than most of the other metals.

What is Magnesium Die Casting Tooling?

Magnesium die casting tooling is an equipment that will assist with shaping the magnesium die casting component to a specific shape.

It represents a block with a cavity that forms dimensionally accurate components and allows for quick production.

The tooling has two halves, the feeding, and ejector portions.

Besides, you can use either permanent tooling that you can use repeatedly or temporary tooling that you will discard after use.

How Does Moving Die And Fixed Die Compare In Magnesium Die Casting?

Magnesium die casting uses two hardened dies that assist in forming suitable magnesium die castings.

Here is how these two compare:

Fixed Die

This die portion does not move and enables molten magnesium metal to move within it.

It will float towards the moving die once the molten metal is shaped.

Also, you will secure the fixed die to a stationary part of the mould.

Moving Die

Here, the ejection portion of the mould attaches to the die.

The ejector pins assist in ejecting the magnesium cast component and the runner.

Also, it will uniformly drive the pins to eject the molded portion effectively while maintaining its properties.

Which Defects Are Common During Magnesium Die Casting?

These include the following:


This happens when you use an extremely high injection pressure and the force of the clamps is very low.

Unfilled Sections

This occurs when you have an insufficient shot capacity.

Also, it may happen due to a slow injection or when you use a low pouring temperature level.


This will occur when you use an extremely high injection temperature or the rate of cooling is non-uniform.

Hot Tearing

This will happen when the rate of cooling the molten metal is non-uniform.

Ejector Marks

This will happen if the cooling duration is short or when the force of ejection is very high.

What Are Some Design Rules In Magnesium Die Casting?

These include the following:

Wall Thickness

Lower the maximum thickness of the wall of the component to minimize the cycle time and part volume.

Also, you will minimize defects when you have a uniform wall thickness as it will ensure the cooling rate happens uniformly.


Use round corners to minimize the concentration of stress and fracture.

Also, the thickness of the inner radius should be equal to or more than the wall thickness.


Ensure you use draft angles to all the walls in a parallel direction to the parting direction.

This will enhance the removal process of the component from the dies.


Here, you will lower the number of external undercuts.

External undercuts need side-cores that will increase the die casting cost.

Also, you can relocate the parting line to form a simple external undercut.

What Factors Will Affect The Cost Of Magnesium Die Casting?

These include the following:

Tooling Cost

The tooling cost contains two parts, the cavity machining and die sets.

Besides, the price of the die set is determined by the dimension of the envelope component.

Material Cost

Here, the cost is influenced by the material weight needed and unit cost.

The weight is determined by the volume and the density of the material.

Production Cost

This is a calculation of the cycle duration and the hourly rate.

Besides, the hourly rate and the dimension of the die casting equipment are proportional.

How Does Multi-Slide Tooling And Conventional Tooling Compare In Magnesium Die Casting?

Here is how these two compare:

Multi-slide Tooling

This tooling has several benefits such as:

  1. First-time net shape
  2. Complex shape and tight tolerance at a high speed
  3. Less part-to-part alteration than conventional tooling
  4. It will eliminate secondary processes such as machining and assembly
  5. The compact tooling is less prone to the parting-line variety

Conventional Tooling

This tooling is made with several or single cavities.

Besides, it is efficient and reduces secondary processes that minimize cost.

Other advantages include:

  1. Steel dies that are braced to increase their longevity
  2. The dies are efficient enough to manage high productions
  3. Effective production with cooling and the water lines that are suitably planned
  4. Net die casting shape avoids secondary processes

What Is High Pressure Magnesium Die Casting?

This is a rapid and accurate technique of forming parts that you can make from magnesium.

Besides, it will offer the quickest way from molten magnesium to the final cast.

Also, it injects the molten magnesium into a steel mould enabling it to solidify in high pressure before conducting ejection.

What Are Some Types Of Cold And Hot Chamber Magnesium Die Casting Processes?

These include:

Low Pressure

This is suitable for magnesium alloys with low melting points and will enhance accuracy and utilization.


This process improves strength and causes minimal porosity.

It uses a cylindrical vacuum that forces molten magnesium in a mould cavity.

Squeeze Casting

Here, you will cast the molten magnesium alloy with no turbulence or trapping the gas.

Also, it happens under high pressure to form dense, high quality, and heat treatable parts.

Semi-solid Casting

In this process, you will use semi-solid billets to produce dense and heat treatable magnesium die casting.

Also, the cast has low porosity.

What Is Draft Angle In Magnesium Die Casting?

This is the angle or slope that you will include on the walls of the magnesium die casting mould.

Also, it will make the opening of the magnesium die casting wider than the base.

What Factors Affect The Lifespan Die Cast Magnesium Parts?

These entail the following:

Stress Concentration

The stress endurance of the mold needs to withstand the pressure levels.


For the machine to ensure different stress concentrations, you need to perform suitable finishing.

If you fail to perform this, the mold will deteriorate quickly.

Heat Treatment

When heat treatment and stress surpass the yield limit, the mold will occur.

Besides, thermal stress can make the mold fail early or quenching of the components.

Grinding And EDM

If you fail to conduct the grinding time properly, grinding cracks occur due to high surface stress and tissue alteration.

Production Operation

Ensure you perform injection and ejection at suitable time frames so as not to affect the molds.

What Are The Benefits Of Heat Treatment In Magnesium Die Casting?

These include:

  • Minimal surface oxidation that causes minimal deformation
  • Highly durable molds offer case hardening causing minimal fracturing
  • Increase the machinability of molds
  • Minimal surface decarburization
  • Low operation costs as mold become flexible
  • Increase in resistance to heat, wear, and corrosion
