Metal casting services involve the shaping of free-flowing liquid metals through the use of dies, molds, or patterns. Castings are generally roughly finished due to the nature of their production. In many cases, additional finishing is required to remove burrs and other artefacts of the casting process. Metal castings services are used to design a wide range of components and finished products. Everything from simple nails and fasteners to engine blocks can be fabricated using metal casting services. Common metal casting processes include sand casting, die casting, permanent mold casting, investment casting, centrifugal casting, and lost foam casting.
Sand casting is used to make large parts (typically iron, but also bronze, brass, aluminum). Molten metal is poured into a mold cavity formed out of sand (natural or synthetic). Sand castings generally have a rough surface, sometimes with surface impurities and surface variations.
zinc Die Casting
Die-casting includes a number of processes in which reusable dies or molds are used to produce casting. The die contains an impression of the finished product together with it’s running, feeding and venting systems. The die is capable of a regular cycle and of (quickly) dissipating the heat of the metal poured into it. Once the liquid metal has cooled sufficiently, the mold is opened and the casting can be removed and finished.
In permanent mold casting, molten metal is poured into cast iron molds, coated with a ceramic mold wash. Cores can be a metal, sand, sand shell, or other materials. When completed, the molds are opened and the castings are ejected.
Investment casting services involve molding patterns by the injection of a special wax into a metal die. The patterns are assembled into a cluster around a wax runner system. The ‘tree’ of patterns is then coated with 8-10 layers of refractory material. The assembly is heated to remove the wax. The hot mold is cast, and when cool, the mold material is removed by impact, vibration, grit blasting, high-pressure water blasting or chemical dissolution leaving the castings, which are then removed from the runner system.
Centrifugal casting
Centrifugal casting services are used to produce castings that are cylindrical in shape. In centrifugal casting, a permanent mold is rotated about its axis at high speeds as the molten metal is poured. The molten metal is centrifugally thrown towards the inside mold wall, where it solidifies. The casting is usually a fine grain casting with a very fine-grained outer diameter, which is resistant to atmospheric corrosion, a typical need with pipes. The inside diameter has more impurities and inclusions, which can be machined away.
magnesium die casting
Lost foam casting
Lost foam casting (LFC) is metal casting services that use foam filled patterns to produce castings. Foam is injected into a pattern, filling all areas, leaving no cavities. When molten metal is injected into the pattern, the foam is burned off allowing the casting to take shape.
Die casting
Die casting and metal casting includes a number of processes in which reusable dies or molds are used to produce casting. The die is capable of a regular cycle and of (quickly) dissipating the heat of the metal poured into it. Once the liquid metal has cooled sufficiently, the mold or is opened and the casting can be removed and finished.
In the die casting process, molten metal is injected under pressure into a reusable mold or die. The die contains an impression of the casting together with it’s running, feeding and venting systems. The die is capable of a regular cycle and of (quickly) dissipating the heat of the metal poured into them. Once the liquid metal has cooled sufficiently, the mold or is opened and the metal casting can be removed and finished.
The high pressure die casting process is the most widely used, representing about 50% of all light alloy casting production. Low pressure die casting currently accounts for about 20% of production and its use is increasing. Gravity die casting accounts for the rest, with the exception of a small but growing contribution from the recently introduced vacuum die casting and squeeze casting process. the design of low pressure and gravity die casting dies for improved die filling, optimized solidification pattern and maximum yield. Gravity die-casting is suitable for mass production and for fully mechanized casting. Low-pressure die casting is especially suited to
Aluminum Die Casting
the production of components that are symmetric about an axis of rotation. Light automotive wheels are normally manufactured by this technique.
Die casting metals can vary widely, and different die casting companies may have the ability to work with anyone or number of them. Some of the most common metal casting types include aluminum die casting, brass die casting, lead die casting (the most popular for model die casting), magnesium die casting, and zinc die casting.

Metal casting is highly crucial in modern manufacturing. It is technically shaping the whole world. As you know, you can create a wide range of metal parts from this method. High Pressure Die Casting is one of the most popular metal casting methods here.
A typical metal casting method pours molten metal into a mold to create complex and precise shapes. Every industry needs these casting parts for many applications. They may need them for structural support or in their main products.
One popular way to shape metal is through die-casting, and high pressure die casting is one of the most common die-casting methods. This method is what this article is mostly about. You will learn about how they are made, their benefits, and how they can be used. You will also find out how HPDC and LPDC are different.
Overview of High Pressure Die Casting (HPDC)
HPDC stands for High-Pressure Die Casting. As the name suggests, this metal casting method needs high pressure. HPDC casting is suitable for making many metal parts with high tolerances.
In HPDC die casting, molten metal is injected into a steel mold or die at high speeds and pressure. As a result, you can create hundreds of casting parts in less time. The pressure needed here is to ensure that the molten metal fills the detailed feature of the die. Because of this, high-pressure die casting is suitable for high-volume production.
An high pressure die casting machine is made up of several primary components. All of them are very important to the system. You might also find other parts, though. However, these four parts are the most important things in high pressure die casting process. They usually decide how good the casting parts are in the end.
Die Cast Molds
Die-cast molds, or dies, are high pressure die casting machine parts that generally determine the final shape. They have two main halves: stationery and movable. They are usually made from high-strength steel. Making these HPDC die-cast molds is called high pressure die casting tooling. Note that HPDC tooling is crucial for the best quality of metal casting.
Ejector Pins
Ejector Pins are another important components in high pressure die casting mold. They facilitate the removal of the solidified cast from the die. You can find these pins within the movable die half. Once your metal casting is cooled and solidified, you can actuate these pins to remove it. It mainly plays a crucial role in the production cycle.
Cold chamber die casting machine
Cold chamber die casting machine is a most important machinie which has injection system, press system, ejection systems and so on. all of die casting process will be done by this cold chamber die casting machine.
Heating Components
Heating components may include furnaces and heating elements. They typically do not melt the metal but keep the temperature constant. The main goal of this high pressure die casting machine part is to ensure the metal is in liquid form. Note that consistent heating is crucial for the quality and consistency of the final castings.
How DoesHigh Pressure Die Casting Work?
Generally, high pressure die casting works in five steps. Each step is crucial for the final quality of the castings. Therefore, when starting a die-casting process, always inspect the device. Check for any defects or loose screws. Always tune your device to its optimal settings. Check whether the cooling system is properly working or not.
Once you have checked your device correctly, you can proceed to the primary high pressure die casting process. Always wear safety gear, such as gloves, clothes, and glasses.
Step #1 Preparing the Die Cast Mold
You can prepare the high pressure die casting mold in two main steps. First, if it has already been made, check it for defects and contamination before using it. Second, designing the mold is necessary for customized products.
Designing a die-cast mold has several stages. First, you can draw your design using 3D software like SolidWorks, AutoCAD, and more. Ensure you have properly organized the gate runner and mold base when designing it. The cooling system is also a crucial part of this design process. Finally, check the venting & ejection system.
Once you are done with the design, proceed with the draft analysis. You can check its functionality on various simulation software. After testing and quality inspection, you can use the die casting tooling for your final production.
Step #2 Molten Metal Injection
In this HPDC casting process, the machine injects molten metal into the die cavity. Unlike other methods, high-pressure casting uses high pressure and speed for this job, which is why it is called high-pressure die casting.
First, tightly connect the two halves of the die-casting mold. Then, with a button push, the HPDC machine forces the molten metal into the chamber. This pressure technically ensures that the molten metal fills the entire cavity. Once the injection is done, the molten metal is allowed to cool and solidify.
Two primary injection methods are used in the HPDC die-casting system. You can choose the correct method for the job based on your project needs.
Hot Chamber Injection
When your injection mechanism is immersed in the molten metal reservoir, it is called hot chamber injection. When the plunger moves, it draws the molten metal into the chamber and injects it into the die cavity. This type of injection is suitable for metals with low melting points. You may often find this hot chamber die casting machine is used zinc and magnesium alloys.
Cold Chamber Injection
Cold chamber injection, on the other hand, uses a separate melting furnace. You can pour the molten metal using a manual or automated system. In manufacturing, the automatic system is generally operated by a hydraulic plunger. It forces the molten metal to insert into the mold cavity. Cold chamber injection is a common technique for aluminum HPDC casting.
Step #3 Cooling & Solidification
After injection, the molten metal quickly cools within the die cavity. Some factories, like CNM TECH, use controlled cooling. During this time, you must ensure proper solidification.
Note that adequate cooling is mainly necessary to avoid defects. As you know, several defects occur due to inappropriate cooling. Some defects are hot spots, cold shuts or misruns, shrinkage, and porosity.
Cooling channels within the die typically stabilize the temperature. You must ensure these cavities are correctly designed when designing a die-cast mold. At CNM high pressure die casting Factory, our experienced engineers always test these cooling systems. Thus, our metal casting has almost zero defects.
Step #4 Ejection
Once the metal alloy part has cooled and solidified within the die, eject it using the ejector pins. Carefully do this step to avoid any external damage. The ejector pins usually facilitate this removal process. They are on the movable part of the die-cast mold.
Step #5 Trimming & Finishing
After removing the metal part, you may find some extra material on the body. You may need some additional finishing processes to get it in good shape. You can perform trimming, grinding, or other surface treatment methods.
The trimming method usually removes excess material from the metal part. It can be manual or automated. However, a smooth surface may need grinding, sanding, or machining. These methods can help you achieve the desired dimensions.
If you need more finishing, you can use different aluminum surface treatments. There are many ways to do this. These techniques can help your HPDC casting parts be more robust and less likely to rust. The most common methods are black or clear anodized aluminum, painting, powder coating, e-coating, and more.
After all this, your HPDC casting parts may need testing for certifications. Note that certifications create customer trust and reliability in real applications.
What are the Key Features of High-Pressure Die Casting?
In the previous section, we discussed the HPDC die-casting process in detail. As you know, in the HPDC casting process, the machine pours molten metal into the die or mold cavity at high pressure and speed. This technically provides several advantages. Let’s check them one by one.

Feature #3 Better Surface Finish
The HPDC casting process also produces a better surface finish. The molten metal fills every corner of the mold cavity under high pressure. Because of this pressure, the density of the metal part also remains the same. Because of this, the surface gets a better result after it cools.
Feature #4 Increased Productivity
The high-pressure die-casting process works very fast. In some manufacturing, this process is fully automated. However, whether manual or automated, it is still faster than other methods. Because of this, you can make hundreds of metal parts in less time. This increases your productivity and reduces costs.
Feature #5 Work with Thinner Wall Products
Again, the high-pressure molten metal fills every corner of the mold cavity. This technology allows you to work with thinner-walled products. Some typical examples are engine components, housings, and heat sinks.
Feature #6 Better Quality
High-pressure casting parts are famous for their high quality and consistency. The controlled process parameters and precise molds always give you uniform castings. This consistent quality ensures better mechanical properties. Specifically, the casting metal parts can have more strength and durability.
Feature #7 Durable Dies
Finally, the tools used in HPDC casting are usually made of good steel. These molds or dies can easily handle high pressure repeatedly. Overall, durable dies eliminate the need for frequent replacement. Once created, they can make thousands of metal parts repeatedly, reducing production costs.
