When it comes to metal casting, both squeeze casting and die casting offer unique advantages depending on the requirements of your project. These widely used processes share some similarities, but key differences set them apart in terms of performance, product quality, and applications.
In this guide, we’ll explore the principles, benefits, and differences of squeeze casting and die casting to help you make an informed decision on which process best suits your manufacturing needs.
Die Casting
The “die casting” mentioned in this article refers specifically to high-pressure die casting. Its principle is to use high pressure to inject molten metal into a precise mold cavity, and then the molten metal cools and solidifies under the pressure to form a casting. The typical characteristics of die casting are high pressure and high speed.
Squeeze Casting
Squeeze casting, also known as liquid forging, is a manufacturing technology that combines casting and forging. It is an improvement over traditional die casting and can effectively eliminate common casting defects such as shrinkage and porosity. Its typical characteristics are low-speed filling and high-pressure feeding and solidification.
Similarities Between Squeeze Casting And Die Casting
Squeeze casting is an improvement on the traditional die casting process and there are some similarities between them.
The same working principle. The basic principles of squeeze casting and die casting are both based on liquid metal molding, and both involve the process of filling and solidification of liquid metal under pressure.
Both are highly efficient. Because of their efficient production processes, both squeeze casting and die casting are suitable for casting large quantities of parts. Both processes can further improve production efficiency through automation and intelligence.
Both can cast precision parts. Squeeze casting and die casting parts are produced with high dimensional accuracy, thanks to the precise mold. Consistency and reliability of parts can be ensured through the design, machining, and maintenance of molds, as well as the control of process parameters.
Both are widely used. The applications of squeeze casting and die casting involve automotive, electronics, telecommunications, aerospace, medical, and other industries.
Differences Between Squeeze Casting And Die Casting
Although squeeze casting and die casting have certain similarities, they have obvious differences in the following five aspects.
Different filling speed. Die casting filling speeds up to dozens of meters per second (usually 30-60 m / s), while the squeeze casting filling speed is only 0.4-0.7 m / s. The reason for this is that squeeze casting requires the molten metal to fill the mold in a laminar flow state, which can reduce entrained air.
Different pressure standards. Squeeze casting pressure is generally close to or even more than 100 MPa, while die casting is generally only a few tens of MPa. This is because squeeze casting requires the realization of high-pressure shrinkage and dense internal grain.
Different pressure purposes and transfer methods. In die casting, the main function of pressure is mold filling. In the subsequent pressure holding process, the gate solidifies first due to its small area, and the pressure cannot fully act on the parts during the pressure holding period; while the gate of squeeze casting is larger, so the pressure transmission is smoother. The parts solidify and form under more pressure.
Different product quality. Die-cast products are characterized by complex shapes and high dimensional accuracy, but there are pores inside that cannot be heat treated. However, there are no casting defects such as pores, shrinkage porosity, cracks, etc. inside the squeeze casting products. Their mechanical properties far exceed those of die castings and are close to or even exceed those of forgings.
Different applications. Die casting is mainly used to solve the forming problems of thin-walled complex parts, so it is mainly used to produce complex, thin-walled parts, and people do not have excessive requirements for the mechanical properties of die-casting parts. Squeeze casting is mainly used to solve the density problem of thick-walled and important parts and to produce castings with high-performance requirements.
