Design of aluminium die-casting molds


Our internal design office is the first and most important step to produce a die-casting mould. Our technicians work together to study and realize the most suitable solutions to satisfy our clients’ demands. In order to achieve these competences, Pialorsi Stampi keeps investing on their capability to quickly intervene in solving problems that can occur. The know-how acquired is for us a valuable resource to support our clients during the feasibility analysis of product and process, and to offer an after-sales technical support.

We use the best hardware and software technologies to produce our die-casting molds.

Not only we use our knowledge learnt with the experience, but we make use of notions acquired during focused training courses as well.
In particular, these courses have been made at the HPDC School.
Through them our staff is specialized in handling the entire process, from the design to the use of the mould in the foundry.


Before starting with the design of the mold, it is necessary to analyse the feasibility of the project through the study of some important aspects.


The dimensions of the part to produce is one of the first aspect that we have to consider, even during the quotation and feasibility phase. It is indeed relevant to be able to calculate the injection gate and the dimensions of the mould.


An important characteristic of the die-casted part is its geometry. During our mould-maker’s history we produced molds for components that had both simple and complex geometries. Both of them requires focused and in-depth studies and the tools are developed and checked in the same way during the whole production process.


The number of cavities mostly depends on the forecasted quantities: based on this information it can be decided if the best solution is a one-cavity or a multi-cavity mould.

During the production of a multi-cavity die-casting mold it is necessaty to pay more attention to the filling phase and the position of the cavities. To offer the best possible result we use a filling simulation software.


As we produce moulds for different sectors, it is important to do analysis before realizing the tools, so that we can offer the best product. The final use of the component for which the mould is produced is relevant during the analysis and design phase: our technical office evaluates the criticalities of the part, that can vary depending on whether it is e.g. an aesthetical o a functional component. Furthermore, thanks to our experience and our formation, we conduct studies to consider which steel would be more suitable for one mold, as well as its specific treatments and coating.

The analysis phase described above is fundamental to organise the project in the best possible way.

Once a first analysis is done, the very first step of the design begins. Our technicians set the 3D project of the mould, constantly keeping in touch with the client, sharing the developments and discussing with the foundry in order to produce the mold basing on its needs.
When the project is finished and we receive the client’s approval, a specialist person creates the tools’ programs with a CAM software, basing on the data created by the technical office.
