¿Qué es la fundición a alta presión?

If you’re considering investing in a new machine to produce your own parts, you may be wondering what is high pressure die casting. In this article, we’ll discuss what this process can do for you and how it can improve your bottom line. High pressure die casting produces smooth surfaces that can accept a variety of finishes. The quality of the die finish determines the type of finish you’ll be able to apply, ranging from paints to coatings. Although it’s a highly efficient process, it is also costly, and there are a variety of disadvantages to consider, including high investment costs and low start-up costs.


High pressure die casting is the most common method for manufacturing large quantities of aluminum or zinc parts. Although this method is fast, it has some drawbacks. For one, it is very expensive, so it is best reserved for very large production runs. Secondly, this method is more complex, and therefore should only be used in very high volumes. However, there are some benefits to it. Below, we’ll examine some of those.


Among the many advantages of high pressure die casting, one of the most important is the ability to produce large volumes of identical parts at a low cost. This method is especially useful for large-scale production runs, as it reduces labour costs and improves product quality. CMP offers comprehensive solutions in aluminum and zinc pressure die casting. These two base alloys are the easiest to die cast, and they also offer outstanding impact strength and ductility.


Precision die casting is an effective method for manufacturing complex parts. It uses a process known as high pressure die casting. It produces parts with high accuracy and reliability, and can be used in virtually any engineering machine. A high-pressure die is an important part of the production process, as it helps to prevent cracking and splintering during the manufacturing process. High-pressure die casting is one of several processes for precision engineering parts.

Inhomogeneous microstructures

Inhomogeneous microstructures are the result of the onset of deformation during high pressure die casting. In this study, we investigated the influence of HB hardness values on the microstructure of die casting by comparing three working cycles. The results showed that there was no difference in the hardness of the parts exhibited by the two casting cycles. In addition, we explored the correlation between the location of the cavities and their size.

Dies that can compensate for turbulent filling

In direct SC, melt quantity is the main driving force. The lack of turbulent filling can be compensated for by reducing the thickness of plate walls. High-pressure die casting processes also require precision control systems that help achieve the desired dimensional accuracy. For example, Lynch proposed using a compensating hydraulic piston, which controls the exact volume of metal in the die. Other solutions include overflows. For complex geometries, the direct SC process can be used to compensate for turbulent filling.

Types of machines

High pressure die casting machines can be divided into three basic types. These machines are used for the production of high-precision parts, such as fasteners and attachment devices. The different types of die casting machines include hot-chamber machines and cold-chamber machines. The former is known as a gooseneck machine because the pressure chamber is directly connected to the mold cavity, which feeds molten metal into the casting die continuously. These machines are generally faster than cold-chamber ones.

Alloys used

High pressure die casting is the process of pouring metal into a mould at extremely high pressure. This technique provides thinner parts than other casting processes, and is particularly good for applications requiring corrosion resistance. High-pressure die casting typically consists of an alloy consisting of 90 percent tin, six percent antimony, and four percent copper. Copper is included to make the alloy more durable. Tin alloy die castings generally weigh less than ten pounds and seldom exceed one-third of an inch thick. These parts are valued for their high resistance to alkalis, acids, and water.
