Die casting of metals is one of the most complex casting methods, both technically and technologically, where there is a multitude of factors influencing the production of quality castings.
Use PoligonSoft to identify potential defects at an early stage of technological design and to achieve an effective technology, as well as to reduce testing and expedite the implementation of casting into production.

Prevent and correct casting defects, such as porosity, air inclusions, or solidification issues.
Experiment with different variables of the casting process to find the most efficient configuration.
Injection point of the molten metal
Gating system
Inserts (Steel 40ХМФ)
Internal feeders
Aluminum Alloy - AK7ch (AL9)
Mold - Steel 12Х18Н10Т
Mold Preheating - 150°C
Insert Preheating - 200°C
Pouring Temperature - 700°C
Metal Supply Speed - 1.5 m/s
In this experiment, the metal supply is performed at a constant speed. However, the system allows for the configuration of any supply dynamics or setting the dynamics based on the speed of the injection piston's movement.

Porosity of 1% and higher
Porosity of 10% and higher
Porosity of 50% and higher
As a result of the calculation, we observe the formation of porosity reaching the surface of the casting, as well as the presence of shrinkage cavities in the body of the casting.
This defect is due to the metal in the feeders solidifying before the complete solidification in the body of the casting.
By modifying the volume of the feeders or introducing changes in the preheating scheme, it is possible to alter the dynamics of solidification.
PoligonSoft allows for the calculation of all possible modes and achieving a positive result already at the design stage.
