High pressure die casting, or hpdc die casting, makes metal parts by pushing melted metal into steel molds with high pressure. This way, the parts are strong and very exact. They also look smooth and nice. Many industries use aluminum hpdc die casting. For example, car makers use it for engine blocks. People who make planes use it for light but strong parts. Electronics companies use it for laptop cases and other items. Medical equipment makers use it for things like surgical tools. Telecom die-casting uses this method too. It helps make tough cases for their devices.
Industry | Applications |

HPDC Die Casting Explained
What Is High Pressure Die Casting?
High pressure die casting is a process that shapes metal parts by forcing melted metal into a steel mold. The machine uses very high pressure to push the metal into every corner of the mold. This method creates parts that have smooth surfaces and exact shapes. Many factories use high pressure die casting to make parts for cars, electronics, and other products. The process works well for making many parts quickly. It also helps companies save material because the molds can be used again and again.
Note: High pressure die casting works best with metals like aluminum, zinc, and copper alloys. These metals melt easily and fill the molds well.
Key Features of HPDC
HPDC die casting stands out because of its special features. Here are some key points:
Speed: The process makes parts fast. Machines can produce thousands of pieces in a short time.
Accuracy: Each part comes out with the same size and shape. This helps when parts must fit together perfectly.
Surface Finish: The parts look smooth and shiny. Many do not need extra work after casting.
Complex Shapes: HPDC die casting can create parts with small details and thin walls. Designers can make shapes that are hard to produce with other methods.
Strength: The parts are strong and last a long time. They work well in machines and devices that need tough materials.
A table below shows how HPDC die casting compares to other casting methods:
Feature | HPDC Die Casting | Sand Casting | Investment Casting |
|---|---|---|---|
Speed | High | Low | Medium |
Surface Finish | Excellent | Rough | Good |
Detail Accuracy | High | Low | High |
Part Strength | High | Medium | Medium |
HPDC die casting gives companies a way to make strong, detailed, and smooth parts in large numbers. This process supports many industries that need reliable and high-quality components.
High Pressure Die Casting Process Steps
High-pressure die casting has several careful steps to make metal parts. Companies like MORELUX use robots and check quality at every step. This makes sure each part is made well. Here are the main steps in the process.
Mold Preparation
Mold preparation comes first in hpdc die casting. The machine uses steel molds called dies to shape the metal. Workers or robots spray a special oil inside the mold. This oil keeps the mold cool and helps the part come out easily. The way the mold is made is very important. It affects how strong and accurate the mold is. A good mold can be used between 80,000 and 150,000 times.
Some important things in mold preparation are:
The gate and runner system helps metal flow smoothly.
Vents let air out so bubbles do not form.
Cooling keeps the metal hardening fast and stops mistakes.
The ejection system helps remove the part easily.
The right wall thickness and draft angles help the mold work better.
A good mold design also stops problems like holes or cracks. MORELUX’s engineers use special die-casting to make sure each mold is perfect.
Key Consideration | Description |
|---|---|
Mold Design | Controls accuracy, durability, and efficiency |
Cooling System | Helps metal solidify quickly and reduces defects |
Gate and Runner System | Guides metal flow and helps with part ejection |
Venting | Lets air escape to avoid bubbles or weak spots |
Wall Thickness & Draft | Makes part removal easier and improves mold life |
Metal Injection Methods
After the mold is ready, metal injection starts. The machine melts metals like aluminum, zinc, or copper alloys. Each metal is good for different reasons. Aluminum is light and moves heat well. Magnesium is strong and not heavy. Zinc is easy to melt and flows well.
The machine pushes the melted metal into the mold with high pressure. This makes the metal fill every small space and shape. The pressure stays high until the metal cools and gets hard. This step makes the part smooth and strong.
The main steps in high-pressure die casting are:
Prepare the die: Spray oil and close the mold.
Fill: Push melted metal in with high pressure.
Solidify: Keep pressure until the metal cools.
Eject: Open the mold and take out the part.
Shakeout: Remove extra metal from the part.
Hot vs. Cold Chamber
There are two main types of machines: hot chamber and cold chamber. The type depends on the metal used.
Aspect | Hot Chamber | Cold Chamber |
|---|---|---|
Molten Metal Source | Metal stays in a heated chamber | Metal is melted in a separate furnace |
Metal Temperature | Always kept hot | Injected only when needed |
Cycle Time | Faster, less than 60 seconds | Slower, about 60-120 seconds |
Metal Alloys | Best for low melting point metals | Good for high-melting-point metals |
Hot chamber machines are good for zinc because it melts at a low temperature. Cold chamber machines are better for aluminum and copper alloys because they need more heat.
Part Removal and Trimming
When the metal cools, the machine opens the mold. Ejector pins push the part out. This is called part removal. The part may have extra metal called flash or runners. Workers or robots cut off this extra metal with a trim die or saw. Robots help make this step fast and correct.
Sometimes, the part needs more work like grinding or sanding to make it smooth. Any leftover metal can be melted and used again. This saves money and helps the environment.
MORELUX uses robots and machines for part removal and trimming. This makes sure each part is high quality and ready to use.
Tip: Checking quality is important at every step. Inspections, material checks, and watching the process help stop mistakes and make sure each part is right.

Advantages of High-Pressure Die Casting
Speed and Efficiency
High-pressure die casting is very fast. Machines make parts in seconds or about one minute. This is much quicker than other ways to cast metal. Factories using this process can make twice as many parts as low-pressure die casting. Short cycle times help companies save money. They also help fill big orders quickly.
Cycle times are just seconds or up to one minute.
Productivity is double compared to low-pressure die casting.
Companies save money because production is faster.
Less manual work is needed.
Complex shapes are made in one step, so less assembly is needed.
Precision and Surface Finish
This process makes parts very accurate. High-pressure die casting is one of the most exact ways to cast metal. It is good for parts that need tight sizes. The smooth walls inside the die and high pressure make a nice surface. Parts often need little or no extra work after casting.
Die cast parts have smoother surfaces than sand cast parts.
Sand casting leaves rough surfaces that need more work.
Die casting makes parts ready to use with little extra work.
Machining, deburring, and polishing can make the finish even better.
Complex Shapes and Strength
Factories use high-pressure die casting to make parts with thin walls and small details. This process can make shapes that are hard to do with other methods. The parts are strong and work well for tough jobs.
Characteristic | Description |
