METALLURGY

Since 1980, Metallurgy has been our main activity and passion until today. It is it that makes us seek excellence and maximum quality in our products, the complete satisfaction of our customers, this is the driving force that constantly challenges us. Over the years, we have acquired experiences with our customers and international suppliers that differentiate us from other companies, both in production and service, making us an absolute reference in Brazil in the manufacture of products and metalworking parts.

PUNCHIONING

Process that allows high productivity with repeatability, besides allowing the execution of operations that maintain the integrity of the treatment in pre-treated parts, such as reamings, edge cuts, recesses, reinforcements, etc.

LASER CUT

Process that allows dimensional and geometric flexibility with high standard of quality and precision, in addition to expanding the possibilities of meeting the specifications of projects and customers, having seen the low level of cutting limitations that the machinery presents.

MACHINING

We have the most complete structure for manufacturing, testing and production of parts and tools in southern Brazil.

Our machining machinery park has more than twenty machines including wire electro erosions, penetration and quick hole, grinding, lathes and various machining and CNC milling plants with the most diverse sizes, from 300mm to 2000mm with a maximum capacity of 2.5 tons. Versatile machines for manufacturing molds, templates and prototypes as well as for the production of serial parts. Our most recent investment made in 2020 was a vertical double column machining machine of high precision and high productivity with advanced performance, intelligent functions and rigid construction. Special double-column design ensures accuracy of extremely high machining through extensive periods of operation, tool magazine with independent input of operation, spindle of 18 000 rpm gives a great finish to the parts and its table with high capacity and access allows to machine large items.

PRESS SHOP

A wide range of mechanical forming processes by means of presses and bending machines (turntables), all with CNC control, guaranteeing precision and high quality. Presses from 40 to 150 ton and benders from 1.2 to 3.0m, which meet the most different demands.

PROGRESSIVE STAMPING PROCESS – HIGH VOLUME

For high production volumes, we have presses with automatic feeding and progressive tools capable of performing stamping, bending and forming operations. They are equipment with high production capacity and repeatability for great demands.

INSERT

We have laser guided equipment for crimping pins, bushings and inserts, with greater agility thanks to the system of automatic feeding and constant pressure of crimping thus avoiding variations.

TURNERY

We have developed in our structure a turning sector of small fasteners, spacers, bushings, weldable pins and similar components. Our park is able to produce serial parts with high productivity, large volume of small- and medium-sized, and small volumes with dedicated designs.

WELDING AND FINISHING

We have highly qualified professionals to perform the most diverse processes of MIG/TIG welding and spot welding, these are our specialties. We also have robots for MIG welding processes that guarantee total control and quality of the process.

FINISHING BY ROUGHING

We have several finishing technologies, with emphasis on brushed finishing on automatic or manual brushing machines in cases where there is a need to finish weld, complex brushing or polishing for parts with more complex geometries.

MIG/TIG WELDING

Welding process with experienced and skilled operators, who have reliable machines and devices.

WELDING BY PROJECTION (SPOT WELDING)

It allows the union between plates without the presence of welding strings with mechanical and structural high resistance.
