This article is a complete Frequently Asked Questions (FAQ) guide for pressure die castings manufacturers. The goal of this guide is to provide you with answers to all the questions you have about pressure die casting manufacturers. It will guide you to make the best decision in choosing a reliable manufacturer for the success of your business.

What Is Pressure Die Casting?

Pressure die casting is a manufacturing process whereby a metal is melted and pumped into a die under high pressure. Then the metal takes the shape of the die upon cooling.

The melted metal fills very small cavities or spaces of the die. This makes it possible for parts of smaller thicknesses or sizes to be molded. In general, high-pressure casting is suitable for molding parts that are less thick and have a smaller size. Below are some advantages of pressure die casting:

  • High-pressure die casting ensures accuracy and precision in the manufacturing of parts or equipment.
  • Pressure die casting is a cost-effective and highly efficient production process in the industrial sector.
  • It also enables higher volumes of production to take place within a short time using the same mold or cast.

What Does Pressure Die Casting Manufacturer Mean?

Pressure die casting manufacturer is a company that uses pressure die casting machines and processes to produce parts, equipment, or tools.

China has some of the world’s leading pressure die casting manufacturers that produce high-quality products for different markets.

Sunrise Metal is your No.1 pressure die casting manufacturer in China and you can trust us with all your die cast needs.

What Are The Types Of Die Castings Used By Pressure Die Cast Manufacturers?

There are two basic types of pressure die castings that manufacturers use. It is important to note that there are other die casting types for different purposes.

Most manufacturers in China and the world at large use the hot chamber and cold chamber pressure die casting.

Hot Chamber Die Casting

Hot chamber pressure die casting-Sunrise Metal

The hot chamber pressure die casting is for metals such as zinc, lead, and copper alloys that have low melting points and high fluidity.

The cylinder of the injector is dipped into the melted metal. The plunger then pushes the metal with pressure into the die. The metal fills the die and takes its shape when it solidifies.

The advantage of this process is that it minimizes the possibility or risk of air getting in touch with the metal.

The disadvantage however is that the rate of corrosion increases.

Cold Chamber Die Casting

Cold chamber pressure die casting-Sunrise Metal

The cold chamber pressure die casting is suitable for metals such as aluminum and magnesium which has high melting points.

In this process, the aluminum or magnesium melted metal is introduced into a cold chamber. The metal is then pushed into the mold by a hydraulic plunger and takes the shape of the mold after it solidifies.

Sunrise Metals is your reliable manufacturer in China to provide your company with the best pressure die castings solutions.

How Does Pressure Die Casting Manufacturers Die Cast Aluminum?

Aluminum die casting uses the cold chamber method of casting due to its high melting temperature.

The heating component of the cold chamber die casting method is separated from the die casting machine.

The aluminum metal is put into a holding or melting container. The holding container is placed on a furnace. The aluminum metal is then heated at a higher temperature until it becomes liquid.

A ladle is used to fetch the aluminum liquid and then poured into the chamber of the die casting machine.

The aluminum liquid is then pumped at high pressure into a mold cavity or die using a hydraulic press system.

The aluminum fills all the mold cavity at a higher pressure. The aluminum in the mold cavity is allowed to cool and become solid. It takes the shape of the mold cavity when it becomes solid.

When the aluminum liquid becomes solid, the die chamber is opened. The solid aluminum is taken out of the die chamber using an ejector.

The solidified aluminum is then sawed to take away unwanted parts. This is because some parts of the die get attached to the aluminum in the process of solidification.

When the aluminum cast is trimmed, it is polished. Some finishing work is also done on the aluminum.

The aluminum cast goes through various degrees of test and inspection to ensure it has no defects. This is also to make sure it meets the desired quality standards.

As the leading pressure casting manufacturer in China, Sunrise has well-equipped laboratories and machines. This helps us to conduct all the relevant tests to ensure our products meet the highest quality standards.

your company can count on us for all your aluminum cast product needs.

What Are The Advantages Of Die Casting To Manufacturers And Their Clients?

Most manufacturers in China and the world at large use die casting for production for a number of good reasons.

First of all, die casting is chosen over other manufacturing processes because it has a high degree of accuracy. Equipment of very complex shapes can be produced by die casting.

The die casting process can be repeated and automated.  Large volumes of products can be obtained within a short time.

Waste is reduced during die casting manufacturing. Die cast products have better product life. There is the stability of tools.

What Materials Are Used By High-Pressure Die Casting Manufacturers?

The materials used for die casting are mostly nonferrous metals. Nonferrous metals are metals with little or no amount of iron.

These include zinc, magnesium, lead, aluminum, pewter, tin, etc.

Aluminum alloy is the most widely used material in die casting. Pressure die casting manufacturers choose aluminum over other materials because it possesses some unique properties and properties.

Aluminum is strong, hard, and light. Aluminum’s strength and hardness increase the lifetime of aluminum die cast products. Its light nature makes it a favorable material for manufacturing lightweight parts or products.

Aluminum is a good conductor of electricity and heat. It is flexible and can be easily molded into different shapes. It is resistant to corrosion and gives cast products an excellent finish.

The most common aluminum alloys used by pressure die casting manufacturers are A380,383, Alsi12, Alsi9CU. A380 is the most commonly used aluminum alloy and considered to be the best among the rest.

What Is The Difference Between Cast Aluminum And Die Cast Aluminum?

Cast aluminum and die-cast aluminum are not the same. For you to understand the difference between the two, we will explain both of them.

Cast Aluminum

In cast aluminum, the aluminum metal is heated using a furnace. It is then poured into a mold and allowed to cool on its own. When it cools, it takes the shape of the mold.

Cast aluminum is used for manufacturing aluminum products on a smaller scale. It does not involve any industrial process.

Die-Cast Aluminum

Unlike cast aluminum, die-cast aluminum is an industrial method of producing aluminum products.

The aluminum metal is melted and injected into a mold or die by applying high pressure to it. Because of the high pressure involved, the melted aluminum is able to fill all the cavities of the mold.

Through this manufacturing process, high precision and complex products are been produced.

High volume production is achieved within a short time through this process.

Die cast aluminum products are stronger than that of cast aluminum. This is because the aluminum is injected into the mold and not poured.

What Are The Major Testing Tools Used By Pressure Die Casting Manufacturers?

As a leading pressure die cast manufacturer in China, we have quality and customer satisfaction as our main goals.

Sunrise has a premium laboratory facility equipped with standard testing instruments, which helps us to achieve these goals.

Some of the equipment at our laboratory are:

What Is The Difference Between Gravity Die Casting And Pressure Die Casting Manufacturing?

Die casting is basically categorized into 3 different forms. They are:

  • High pressure
  • low pressure
  • gravity casting.

The three forms of die casting involve introducing melted metal into a mold to produce equipment or material of specific shape.

They all use non-ferrous metals like aluminum, magnesium, lead, zinc, etc.

The major difference between pressure and gravity die casting is the way the metal is introduced into the mold.

In gravity sand casting, the metal is poured into the mold from the top of the vessel containing the mold. This ensures the mold is filled bottom-up by the force of gravity.

Gravity die casting is used for the production of less complex products. It is also suitable for products with a bigger thickness.

In pressure die casting, the metal is introduced into a mold with pressure. The pressure ranges from 1500-24500 psi.

Due to the high pressure in this type of casting, it is suitable for complex and less thick products or materials. The high pressure forces the molten metal into the cavities of the mold with speed.


What Is The Importance Of Advanced Equipment  In Die Casting Manufacturing?

What Machines Are Used Pressure Die Casting Manufacturers?

There are two types of machines that are used in high-pressure casting manufacturing. They are cold chamber casting machines and hot-chamber casting machine.

Cold Chamber Casting Machine

The cold chamber pressure casting machine is used for casting metals with high melting temperatures like Aluminum.

Cold Chamber Casting

The cold chamber pressure casting machine has the following components:

  • Cold chamber where the melted metal is poured into the Hydraulic system with a cylinder and a piston. This pushes the molten metal into the mold cavity.
  • Mold cavity that is made of steel. The melted metal takes the shape of the mold cavity after it’s been introduced into it.
  • Ejector that is operated to eject or remove the die cast or solidified metal.

How it operates

  • The melted metal is poured into the cold chamber. The mold or die at this stage is closed
  • The plunger in the cold chamber pushes the metal into the mold cavity under high pressure. The mold is opened during this process. The metal is held in position by the piston until it becomes solid.
  • The mold cavity opens. The plunger further pushes forward to keep the cast metal in the ejector die.
  • The ejector opens and the cast metal is released. The piston withdraws back to its original position.

Hot Chamber Casting Machine

The hot chamber pressure casting is used for casting metals with low melting temperatures.  The hot chamber casting machine has a melting container connected to it. The metal is put into the melting container and placed on a furnace for it to melt into liquid.

How it operates

The injection system is lowered into the melted metal. The plunger pushes the melted metal into the die through a feeding system connected to the metal container.  The melted metal is held in position by the plunger until it solidifies. The ejector is operated to release the die cast metal.

Why Do Manufacturers Choose Die Casting Over Other Casting Methods?

Die casting manufacturers choose die casting over other casting methods because of a number of good reasons.

Let’s take the manufacturing of gears as an example.  Gears are very complex in nature and have complex internal structures. It is very difficult to manufacture gears and other complex equipment with other casting methods.

This is where pressure die casting comes in. With pressure die casting, almost any complex machine part or equipment can be manufactured easily with speed, accuracy, and precision.

In summary, die casting is the most preferred manufacturing process because of the following reasons:
