FAQ
VirtualDieCasting is a web portal owned by TF s.a.s. that deals with mechanical design in the world of molds in Villa Carcina (Brescia).
Our job is to design components and molds and to make filling analysis to obtain the maximum quality of the diecasting part.
We have 4 workstations with a total of 50+ cores available to calculate your filling and solidification processes.
We use simulation software that has the particularity of being bi-phasic, that is to simulate both air and metal in every cell of the mesh. During filling only the relative percentage changes but both will always be present. This allows us to be particularly precise in predicting the distribution of trapped air at the end of filling.
The result of our work is one or more reports.
A report will be produced for each analysis requested

Analytical moldable analysis.
Calculation of the theoretical and optimized values taking into account the dynamic performance of the machine, the geometries and the casting requirements, providing an excellent starting point from which to set the parameters in production.
The output is expressed in common language and indicates which problems have been encountered and what corrections can be made to solve them. Production of the PQ2 diagram and simulation of the influence of working conditions on the process, such as, for example, particularly low mold temperatures or simulating the effect of a variation in the number of figures.
Full casting simulation with biphasic die casting simulator.
Metal and air are modeled simultaneously from a mathematical and fluid-dynamic point of view. This feature allows extreme accuracy in the simulation of the filling, including metal pulverization phenomena and movement of air inclusions, allows the correct analysis of vacuum casting, calculation of air speeds and validation of air vents. Parallel to this, analysis and visualization of the filling through animation and images of the distribution of the main variables (speed, temperatures, pressures, etc.) are also available, highlighting the areas where it is possible to have critical speeds, the filling path, the cold points and the cold junctions, the areas where there is the incorporation of air. This information allows to optimize the geometry of the branch and of the casting connections, the position of the overflows and of any air vents or of the vacuum circuits.
At the end the simulation is completed with the simulation of the solidification with virtual mold and heat map deriving from the filling, taking into account the thermophysical properties of the alloy depending on the temperature. Display of solidification times and shrinkage porosities expected.
Simulation of the solidification with virtual mold with uniform temperature equal to that set, taking into account the thermophysical properties of the alloy depending on the temperature.
Display of solidification times and shrinkage porosities expected.
You will have low prices because we use highly efficient machines that allow us to reduce the calculation times together with the use of standardized procedures and formats for analysis and reporting.
The thickness of the part is the most critical parameter to assign. It represents the predominant thickness and/or what we have to obtain with the set quality
VirtualDieCasting is completely Italian and all activity take place in our only Headquarters located in Italy in Villa Carcina (Bs) in via Italia 85.
FILE FORMATS
.STL – Only files with SINGLE parts are accepted, that is the whole casting
MAXIMUM NUMBER OF ELEMENTS FILE.STL: 1 MILLION ELEMENTS
WALL THICKNESS
The nominal thickness of your piece must be greater than 1mm. Pay attention to details less than 1 mm because they usually do not survive to the mesh phase.
CHARACTERS AND LOGOS
If you can, remove all the logos, brands or writings from your model. These usually do not affect the filling fluid dynamics but only complicate the mesh of the part.
If it is not possible, we will delete them and then we will ask you to confirm the operation.
FILETTATURE INTERNE ED ESTERNE
Model threads only if actually present and necessary for the geometric description of the part.
If in doubt, do not hesitate to contact us by clicking here
We accept the .stl formats
MAXIMUM NUMBER OF ELEMENTS FILE.STL: 1 MILLION ELEMENTS
The maximum size is 100Mb per single file or 1 million of elements
If you wish, you can upload the compressed file to a .ZIP file
These export format is present in almost all the most used 3D mechanical CAD: Solidworks, Rhino 3d, Creo, NX, CATIA, Autocad mechanical and many others.

Once the 3D geometry has been loaded and your order has been sent, we will examine it and within one working day you will receive a contact from an expert VirtualDieCasting who will confirm the correctness of the information provided or suggest any changes. So it will always be possible to submit to the VirtualDieCasting experts any questions about the diecasting process and the relationship between it and the geometry of the part, so you can make any changes that may be necessary.
Together with the technical approval of the geometry you will receive a schedule with the expected delivery of the report.
There are 2 fast solutions:
1) By clicking here you can download FreeCAD which is an excellent 3D CAD easy to use but at the same time will allow you to create a professional 3D file: it is a open souce project and it is completely free.
