Mold Design

Spark Plasma Sintering (SPS) technologies mainly use three types of molds: graphite, metallic and composite molds.

Each has its own characteristics and is used for different reasons.

The graphite mold, for example, is the most used for its ability to resist heat, which can reach over 2200°C.

With Engemini, increase mold life, design the perfect parts and increase manufacturing productivity.


Mold size is critical to production cost and part performance. Graphite molds are fragile and can break if not adapted to the SPS recipe and application, thus generating unnecessary costs and additional project lead-time.

Depending on the quantity of powder, the material used, and the pressure required to densify it, the mechanical and thermal constraints of the molds will be more or less important.

These stresses can easily cause breakage or poor thermal homogeneity which will have a direct impact on the sample and can quickly become costly.


The Mold Design module enables digital FAST/SPS mold design and automatically calculates the optimal trade-off between mold size (height and wall thickness), power consumption and thermal homogeneity for any given combination of material and sample size.

Engemini's Mold Design Module strengthens your tool design while reducing thermal gradients within your parts.

By digitally simulating the thermal, electrical and mechanical physics used during the sintering cycle of your sample, ENGEMINI calculates and predicts the optimal dimensions of the graphite mold to use to obtain the strongest, most thermally homogeneous and most conductive tooling. .
