From design to production, every detail of our manufacturing process is carefully managed.
MANUFACTURING
State-of-the-art mold and pattern manufacturing
Since 1968, we have refined a production strategy that enables us to manufacture high-performance, durable molds, patterns, and core boxes that meet our clients’ specific needs.
From the very first contact, we create a tailored synergy to maximize production efficiency, aiming to eliminate the need for interventions during the manufacturing process.
Modelleria Zanchettin collaborates with about fifteen professionals, masters of traditional craftsmanship, who ensure the design and fabrication of equipment using modern 5- and 3-axis CNC machining centers, including the production of prototypes and small batches.
What we develop
Molds and patterns for green sand, resin sand, Disamatic, and shell molding foundries
We manufacture foundry molds and patterns for various processes in the foundry industry, developing custom solutions for green sand, resin sand, Disamatic, and shell molding systems.
Each part is designed by evaluating the required characteristics and tolerances, the clamping system, and the plant’s production conditions, with the goal of ensuring dimensional accuracy, stability during molding, and production continuity.
For green sand molding, we produce patterns designed to work with sands bound primarily with clay and water—a process that requires particular attention to demolding, geometric stability, and proper management of casting shrinkage.
For resin-bonded sand processes, we develop molds and patterns for productions that require greater surface precision, mechanical strength of the mold, and tolerance control—even when dealing with technically complex geometries.
We also manufacture molds for Disamatic systems—high-productivity automated systems that require high repeatability, consistent precision, and perfect compatibility with vertical molding cycles.
For shell molding processes, we produce components designed to ensure surface quality of the casting, thermal stability, and consistency in mass production, while paying particular attention to the precision of mating surfaces and functional surfaces.
Custom Core Boxes
Core boxes for shell molding and shell boxes
Modelleria Zanchettin manufactures core boxes for shell molding processes, designed to ensure geometric precision, production continuity, and the quality of the final casting.
The core boxes are designed based on the characteristics of the casting, the internal geometries to be achieved, and the type of equipment used by the foundry, with particular attention to the stability of the production process and the surface quality of the core.
In the shell molding process, the core is produced using sand pre-coated with thermosetting resins which, thanks to the heating of the core box, allow for the creation of precise, compact, and mechanically strong structures. This technology enables the production of cores with tight tolerances and uniform surfaces, making them particularly suitable for technical machining and mass production.
The design of the shell boxes is developed with the following in mind:
- dimensional accuracy
- ease of coreremoval
- mechanical strength
- surface quality of the casting
- compatibility with the foundry’sproduction process
Using CAD-CAM systems, 3D scanners, and CNC machining, we manufacture custom core boxes for various applications in the foundry industry, combining technological precision with our extensive experience in foundry pattern making.
Where We Operate
Sectors of Application
The experience we have gained in foundry pattern making enables us to handle production for a wide range of industrial applications, while maintaining high standards of precision and production consistency.
The sectors in which we primarily operate are:
- General Mechanics
- Pumps
- Engineering
- Earthmoving
- Hydraulics
- Prototyping
- Furniture
Preserving our artisanal expertise has also allowed usto expand into the design sector, which joins the sectors mentioned above—all of which have relied on our model-making shop as a trusted partner for over fifty years.
