Understanding the underlying reasons why aluminum casting techniques are so diverse and present in so many aspects of our daily lives is essential to properly meet industry requirements. The study of low-pressure casting methods is crucial for the production of high-quality aluminum products and in this report we will provide an overview of these methods and their advantages. To better understand the impact and importance of this process in industrial applications, we detail the uses and functionalities of aluminum die casting.

The Place of Aluminum in Casting Methods

Aluminum casting is one of the most fundamental methods of manufacturing metal parts. In industrial processes, we apply various techniques to realize the casting of this lightweight and durable metal. In general, aluminum casting methods can be grouped under the following headings:

• Sand Casting: Aluminum sand casting is widely preferred because it is flexible and economical. This method is particularly suitable for producing parts with complex geometries.
• Mold Casting: In aluminum die casting, the metal is injected into the mold under high pressure. High production speed and good surface quality are among the advantages of this method.
• Coclay Casting: The aluminum gravity casting technique is made using reusable metal molds. It is ideal for obtaining good thermal conductivity and high mechanical properties.
• Pressure Casting: It is a method used especially for the production of high-volume aluminum parts. It is possible to obtain parts with excellent surface finish.
• Low Pressure Casting: Low pressure casting method has a special place among aluminum casting techniques. Aluminum transferred to the mold with low pressure makes it possible to produce high quality castings.

We understand the unique position of aluminum among casting methods and the importance of producing according to the requirements of each of these techniques. Low pressure casting is a method that offers excellent results, especially in the manufacture of parts that require precision and control. We prefer low pressure casting to achieve high strength, low porosity and excellent surface details. This process also has the advantages of reducing material waste and lowering production costs.

Fundamentals of Low Pressure Casting Technique

The low pressure die casting technique is a popular method used in industrial casting processes, especially when working with aluminum and other light metals. We use this method in detail to ensure the production of high quality parts in the industrial field.

The low-pressure casting technique is based on slowly pushing molten metal into the mold under pressure. This process improves casting quality and minimizes the formation of air voids. Here are the basic steps of this technique:

1. Melting and Holding:
   • First, metals such as aluminum are melted and kept liquid in a holding container.
2. Pressure Application:
   • By applying a little pressure on the molten metal, the metal is pushed into the casting mold.
3. Mold Transfer:
   • The metal is molded slowly and in a controlled manner, with gravity contributing to the process.
4. Cooling and Solidification:
   • It cools and solidifies in the metal mold.
5. Subtraction and Final Operations:
   • After cooling and solidification is complete, the part is removed from the mold and the necessary finishing work is carried out.

Among the advantages of this process:

• Less material waste,
• Lower energy consumption,
• This includes the easy production of thin-walled parts and parts with complex geometries.

The most important point to be considered in the low pressure casting technique is the control of the applied pressure. If the pressure is too high, the metal flows too fast into the mold, which can lead to air voids and other casting defects. Therefore, setting the right pressure and casting at the appropriate speed determines the quality standard of the parts we produce. This is a technique that requires careful control and precision, but ultimately delivers superior quality castings.

Advantages of Low Pressure Die Casting Technology

Low pressure die casting technology is a prominent method among industrial aluminum casting processes and offers a number of advantages. Here are some of the key benefits of this technology:

• Better Material Utilization: Low pressure die casting maximizes material utilization and minimizes waste. This is a significant benefit in terms of cost effectiveness and sustainable production practices.
• High Product Quality: The technique improves the surface finish and mechanical properties of castings. Parts produced by low pressure die casting have low porosity, which increases the strength and durability of the product.
• Less Machine Maintenance: Low pressure die casting machines require less maintenance than their high pressure equivalents, thus reducing operating costs.
• Labor Reduction: This method reduces labor costs because most of the operations are automated and there is less need for human intervention.
• Energy Saving: The casting process can be completed using less energy, which saves energy and directly affects production costs.
• Allows Variable Wall Thickness: The low pressure casting method makes it possible to work with variable wall thicknesses in parts, which allows for design flexibility and facilitates casting of complex shapes.
• Environmental Impact: With low gas emissions and waste material generation, the impact on the environment is reduced, making this method an environmentally friendly option.

We optimize our production processes taking into account the above advantages of using low pressure techniques in industrial aluminum casting and aim to achieve maximum efficiency from these technological applications.

Disadvantages of Low Pressure Die Casting Technology

The low-pressure casting process is often preferred in industrial aluminum casting, but it also has some disadvantages. When considering industrial applications, it is important to take these limitations into account.

• Investment Costs: Significant initial investment is required for the low pressure die casting machines and system. Production line setup and maintenance can be costly compared to other casting techniques.
• Production Speed: In the low pressure casting process, the rate at which the metal fills the mold is relatively low. This can be a barrier for applications that require high volume production.
• Mold Costs: Molds are usually quite complex and made of high quality materials, which increases mold costs. Also, molds require special design and craftsmanship for long life under low pressure.
• Limited Use for Large Parts: Low pressure die casting offers limited use, especially for producing large and complex parts. These parts are often more efficiently produced by high-pressure die casting or other methods.
• System Complexity: The system contains complex components that require precise control to improve casting quality and efficiency. This necessitates operator training and continuous monitoring of the system.
• Alloy Restrictions: The use of the low pressure casting method may not be suitable for some alloys. These alloys may not have the appropriate fluidity or strength properties at low pressure.

These disadvantages are among the factors that play a role in the choice of low pressure casting technology and should be taken into account in determining the most suitable casting method for each application. Although this technique presents some limitations, it can be preferred, especially where complex geometries and a high level of surface quality are required.

Stages of the Low Pressure Casting Process

Before starting the low-pressure die casting process, let's review four important phases that are fundamentally focused on reliability and quality. Each stage needs to be carefully planned and executed in order to run the process efficiently and effectively.

1. Mold Preparation:
   • The design and manufacture of the mold is based on the form in which the aluminum alloy will be cast.
   • Mold surfaces are ensured to be smooth and clean.
   • The required heating processes are adjusted so that the casting material flows fully into the mold and cools down.
2. Alloy Preparation:
   • Selected aluminum alloys are melted in the specified composition.
   • During the melting process, any additives and gases that may affect the quality of the casting are removed.
3. Low Pressure Casting:
   • The melted aluminum is guided into the mold using low pressure.
   • The pressure ensures that the melt is filled into the mold slowly and under control.
   • This minimizes the mixing of air into the casting and results in smoother surfaces.
4. Cooling and Extraction:
   • The cast part is cooled slowly before being removed from the mold.
   • The timing of cooling depends on material properties and thicknesses.
   • Careful cooling prevents internal stresses and distortions.

The successful completion of each stage directly affects the quality of the end product. We meticulously monitor and continuously control every step of the low pressure casting process. In this way, we are able to offer high standards in industrial aluminum casting, as well as the flexibility and precision to meet customer needs.

Low Pressure Casting Equipment and Components

In the low pressure casting process, the equipment and components used directly affect the quality, efficiency and economy of the casting. When using these techniques, we carefully select and utilize the following equipment and components to achieve optimal results in terms of both operational excellence and product quality:

• Casting Unit: Low pressure casting units are equipment in which the metal is kept in molten state and the casting pressure is controlled. It consists of a crucible for the casting process, pressure control system and heating elements.
• Mold System: Aluminum casting molds are usually made of high-grade steel and determine the shape of the product. Mold design, cooling channels and surface treatment have a great influence on product quality.
• Rotary Table: Rotary tables, which can accommodate a variety of molds and speed up the casting cycle, are ideal for mass production.
• Microprocessor Control Systems: Microprocessors are used to increase the precision of casting processes. Precise control of variables such as temperature, pressure and timing is achieved.
• Degassing Equipment: Equipment for degassing molten metal is critical to minimize post-casting air bubbles and installation defects.
• Cooling Systems: Cooling systems, which allow the aluminum in the mold to cool rapidly after the casting process, not only improve the mechanical properties of the part, but also reduce production time.
• Feeding System: With the feeding system, which increases the effectiveness of the low pressure method, the flow rate and pressure of the melt into the mold are properly managed.
• Removal Equipment: Robotic removal equipment for demolding cast aluminum parts provides both speed and consistency.

For us, ensuring quality and consistent castings of each part is only possible through the correct selection and management of this equipment and components.
