Manifesto · Prosekon

Our word,
kept
since 1994.

In 1994, a newspaper ad changed everything. A small trophy foundry in Novo Hamburgo became one of the most agile foundries in Brazil. One promise that never changes: meet the deadline.

We are the ones who keep their word — every day, for three decades.
"The basics, done right."

Products

Three decades turning
steel into parts.

Centrifugally cast tubes, rotors, blocks, rods — and everything else made to order in our foundry in Novo Hamburgo, Brazil. For industrial applications where the part cannot fail.

Processes

From design to
finished part.

Five integrated production lines under one roof, with our own metallurgical lab.

01

Gravity casting

From design to final inspection: pattern, cold-cure mold, induction-furnace melting, pouring, cooling, and testing.

02

Centrifugal casting

Seamless tubes via rotating molds. Up to 1,600 kg, Ø 78 to 920 mm — in carbon steel, stainless steel and special alloys.

03

Heat treatment

Controlled cycles for quenching, stress relief, normalization and solution annealing — properties tailored to each project.

04

Pre-machining

In-house lathes for centrifugally cast tubes — pre-machined or final-machined and ready for assembly.

05

Testing in our own lab

Dimensional inspection, hardness, dye-penetrant testing and spectrometry — full traceability part by part, no third parties.

Available alloys

The raw material
of our foundry.

Eight families of alloys certified in our own lab. From carbon steel to 310 stainless, from naval bronzes to special alloys for heat treatment — every part produced with full traceability.
