Welcome to the section dedicated to the models (molds) required by foundries to obtain raw castings in iron, aluminum, bronze, or other metals. Here, you can explore a wide range of options made with high-quality materials such as aluminum, cast iron, steel, and resin.

To ensure the highest product quality, we collaborate with the customer and the foundry in all phases of model design and production. We are responsible for the calculations required for the correct realization of the model, for example:

  • The enlargement of the model is achieved by applying a scaling factor that varies based on the type of casting we intend to produce and the type of molding system used.
  • The application of the necessary draft angles for the removal of the pattern from the sand mold for each casting performed in the foundry.
  • Adding excess material for subsequent mechanical processes.
  • Creating desired logos and texts on raw castings, seamlessly integrated into the production process.
  • Placing the model or multiple models onto the plates designated by the foundry.
  • The creation of pouring channels, with dimensions and specifications provided by the foundry for the proper metal delivery to the casting.

The choice of the most suitable material for model fabrication is a collaborative endeavor between the client and the foundry.

Aluminum models and core boxes

Our cast iron models represent the ideal option for applications that require long-term robustness and durability. This material boasts exceptional dimensional stability and excellent resistance to high temperatures, making it the perfect solution for molds intended for demanding industrial productions.

Moreover, foundries appreciate aluminum models as they can be slightly heated, a feature advantageous in specific atmospheric conditions during the demolding phase.

Models and core boxes in cast iron and steel

Our cast iron models represent the ideal choice for applications requiring durability and long-term resilience. This material boasts exceptional dimensional stability and remarkable high-temperature support, making it the perfect solution for molds intended for demanding industrial production challenges.

Cast iron core boxes are essential for obtaining cores through the “hot” shell molding process, as they can be heated. This approach allows for the production of cores with significantly reduced thickness and an extremely fine and smooth surface finish compared to cores obtained through the “cold” method using aluminum or resin core boxes.

For projects demanding increased abrasion resistance and superior hardness, we offer steel models. These molds exhibit an exceptionally robust structure, ensuring highly precise molding results and even greater long-term durability.

Models and core boxes in resin

In conclusion, our range of resin models offers an ideal solution for those seeking an excellent balance between equipment durability and cost. Especially on larger-sized models, the use of resin allows for optimal utilization of raw material costs and reduction in CNC processing times during model creation, owing to its greater ease of milling compared to metals.

However, it’s important to note that the lifespan of equipment crafted from resin is shorter compared to that of equipment made from metal. Therefore, resin is typically chosen for projects involving relatively moderate production volumes.

Prototypes

We can create physical prototypes in wood, resin, aluminum, cast iron, and steel to assess their geometry, aesthetics, functionality, and integration with other components.

We are confident that our wide range of models in these materials will allow you to find the ideal solution for your molding projects.
