Compacted Graphite Iron – CGI

Tupy is the first casting plant in the world to produce Compacted Graphite Iron (CGI) iron in large scale. CGI provides higher mechanical strength than gray cast iron, traditionally used in engine blocks.

Tupy Tracker + Artificial Intelligence

The Tupy traceability project has the aim of detailing the history of process variables which are important for the final result of the product, thus assuring speed and precision in decision-making:

  • Process control system in each phase;

  • Integration of technologies for process traceability with the cast part;

  • Full traceability of products and processes;

  • Follow-up and monitoring of production process variables on time;

  • Integration between process variables and the final result of the product;

  • Improvement and evolution of the product and quality processes using Artificial Intelligence concepts and technology

Our production process in details

Before production, the Engineering and R&D teams develop projects together with our customers.



Casting is the transformation of the major inputs in cast iron alloys. Raw materials are inserted into cupola, induction and arc furnaces, where they are changed to molten metal at temperatures above 1500ºC.


Core shop

Making cores means the obtainment of sand and resin (“core”) agglomerates, which are molds that shape the part cavities and recesses. “Cores” are fitted in a single set, which will receive the molten metal upon pouring.



It is the process for preparing the sand mold (silica, bentonite, powdered coal, water) by compression against a die (“tooling”) resulting in a negative replica, which will provide the outer shape of the part.



Once the flask is obtained with the “core” and mold prepared, pouring process starts. The metal alloy is “poured” in the core-mold set, where it fills all the cavities, reaching the “tooling” form.



In this stage, the cast part is submitted to steel shot blasting to remove sand and minor metallic burrs. Next, it passes by quality control inspection according to the customers’ specifications.



Machining is a phase carried out after finishing, Where the final dimensions and geometry of the product are checked, enabling its interfaces and assemblies. This stage can be performed at the customer or Tupy premises.


Tupy not only searches for knowledge, especially with universities and research centers, but also generates knowledge. Listed below are some works published or disclosed by professionals that are members of the technological areas in the company, which can be accessed in PDF or DOC format.
