Casting
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.
Molding
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.
Pouring
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.
Finishing
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
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.
