The productive process is initiated in our foundry starting with recycled metal shavings and first-quality scrap metal obtaining brass bars of great proportions for stamping as well as brass ingots (also of great proportions) for faucets and pipe connectors and adaptors. After the elimination of the brass metal shaving unwanted particles, by means of automatic separators, it is dried and introduced in an induction furnace of continuous movement.
Once melted, according to the laboratory instructions, the alignment is corrected by adding copper and zinc, which, in the case of the impression bar, the composition is adjusted to the European norm of 12.165.
This continuously produces three solid bars of great proportions (called “billet” in the professional argot), which are cut to the desired size to be adapted to the extrusion necessities.
In order to proceed with the extrusion, the billet should be preheated to an adequate temperature. Once the temperature of 670 degrees c is reached, it is introduced in the extrusion press to shape the billet. In a totally automatic process, the billet extracted is deposited on a work surface where it is cut to the desired size.
In the last step, the billet is straightened and calibrated until a final diameter is obtained with the corresponding tolerance norms.

The production of the ingot for faucets is carried out in a mobile crucible. The furnace pours the melted metal at a pace synchronized with the velocity of the ingot chain. This velocity permits the ingot to cool sufficiently to proceed to remove from the mold. Metalgrup has all of the necessary means to stop off the waste from the smelting so as not to harm the environment.
Qualified personnel with the most adequate means, such as high precision mass spectrographs, carry out the adjustment control of the composition to the specified norms.
All of the products manufactured by Metalgrup have been previously studied or designed in our technical office which has a design system assisted by a new generation computer where all the necessary plans are designed. Likewise, we also have process and costs software programmed especially for our needs.
Having one of the most modern quality control methods, Metalgrup meets the precision demands of the current market. We also have direct communication with the production control department, achieving a homogeneous and flexible management and control bloc between both departments.

Metalgrup has a workshop for the manufacture and maintenance of molds and matrixes or stamps able to develop any project and cover all the needs of our client manufacture requirements having a team of highly specialized professionals and the depot of machinery necessary.

Our daily process has as a 1st phase the cut of brass blocks with automatic state-of-the- art power saws, each one able to cut up to 10,000 pieces an hour with the precision of 0,5 grams.
In the 2nd phase (stamping), the pieces are heated in natural gas furnaces until the adequate temperature is obtained, between 650 and 750 degrees c. These furnaces automatically and continuously feed each one of the presses to give the necessary shape to the blocks in closed chamber molds, achieving, in this manner, great precision and performance from the machines as well as the molds used. These molds are manufactured with special steel for high temperature work. This steel can maintain mechanical properties up to 550 degrees c, which permits an optimum duration of punches and stamps.
More than 90% of our presses are totally automatic and are especially prepared to rapidly be able to change its mold with a minimum of stop-time.
The 3rd phase (superficial granulating) the remainder of the burned oil is pulled off leaving the pieces clean of impurities and with a granulated matt surface. Upon achieving this necessary superficial finish, we go ahead to the 4th phase: mechanical. The mechanical section is equipped with the most modern state-of-the art machinery on the market due to the elevated production in our previous phase.

Metalgrup S.A. has become part of the world of robotics with the installation of a parts manipulator system that allows us a great production schedule able to maintain a lineal production cycle with a minimum of non-productive times and waiting materials. One hundred per cent of our mechanized machines are equipped with automatic feeders maintaining a constant and sufficient productive rate to obtain the shortest possible production time and the preparation time can be reduced to an acceptable minimum.

Metalgrup S.A. is a company committed to quality and certified according to the iso 9001/2000 norm by APPLUS. All of the personnel at Metalgrup guarantees the quality of the product as well as the supervision. Thus, in the manufacturing process, the primary function of all the personnel is quality control by periodic testing in all the production phases of the dimensions of the product as well as its treatment and aspect. This implanted system allows us to detect any anomaly almost at the exact moment it takes place, being able to correct it with a minimum of internal rejections, in the order of 0,45% over the verification of the product and practically with a non-existent external rejection.
Totally automatic machines perform the packing process leaving the product prepared for transfer to and stocking in the central warehouse.
Despite constant quality control to which we subject our manufactured products, we later control resistance and water tightness of those products requiring it. Some of them, such as the temporized faucets “novo tempus”, are subjected to a process of testing the duration in normal conditions following the European norm that regulates said product. Ninety per cent of our production is normally made against stock, since our clients demand a rapid supply response. This requires us to have available a massive warehouse in order to satisfy the client with a product of the best quality and the most efficient service, as rapid and responsible as possible. Manufacturing of our products is varied so as to fulfill the maximum possible needs of our clients.
Among our multiple lines of production are shower handles and flexible shower hoses in diverse materials that we also market in a high frequency blister. The presentation in a blister is achieved through a system of bubbles created by air absorption and then sealing by means of high frequency welding electrodes.
Once the product has been tested and accepted, it is ready to be shipped to our clients. We personalize the conditioning of the bags if so required, following the client’s instructions, adapting the number of parts, the bar codes and the language of the text to meet the needs of the client.
In this way then, starting from the selected raw materials and with the modern systems of production herein described, the effort of all the manpower team of Metalgrup S.A. is centered on following the day-to-day improvement of quality for each and every one of our processes and services.

Our objective is still the same as the first day: “client confidence and satisfaction on a job well done".
