ALUMINIUM DIECASTING

Diecasting process is highly automated and it’s indicated for high quantity productions of aluminum parts. The melted metal is injected through high pressure hydraulic presses into a metal mold. The mold is made from two half parts (semi-molds) to allow the extraction of the cast piece, once solidified. Thanks to the high technological and quality standards of equipment and machinery, the pieces produced by die-casting ensure very precise dimensional tolerances and excellent surface finishes.

ALUMINIUM SHELL CASTING

The gravity-cast aluminum casting is the ideal solution to produce medium quantities lots. This aluminum melting process consists in using steel molds made from two half parts that form the “shell mold”. The aluminum, previously arrived to the liquid state (680°C) is poured into the molds from which, after the necessary cooling time, the semi-finished products are extracted. Shell casting guarantees a good surface finish, a good dimensional accuracy and excellent mechanical characteristics.

ALUMINIUM SAND CASTING

Sand casting or ground casting is one of the most traditional casting processes that is still used for the production of the pre-series or small series of a metal products. It consists in casting the melted metal inside a mold composed of a special sand (foundry sand), which will be dismantled at the end of the process to be able to extract the piece. This process, which is versatile and extremely basic, allows a finishing product conform at the design that usually need to evaluate the piece for the eventual die casting series.

POLISHING

Before the polishing the aluminum cast article generally requires a cutting operation of the exceeding material. After this first activity, the piece is placed on the automatic robot for the brushing steps with abrasive papers and polishing pastes. The number of the steps depends on the type of finishing you want to obtain: from matt to mirror polished. The automatic robots handle with extreme precision pieces of few kilos as well as pieces over 130 kilos.

LASER

Laser technology provides high accuracy, speed and versatility. In laser cutting the beam of electromagnetic radiation coming from the source is focused on the surface of the sheet to be cut which heats up and quickly reaches melting. At the same time a flow of gas removes the molten material generating the cutting groove. The processing proceeds moving the laser beam and the sheet metal along the programmed cutting path. 2D laser cutting is used to obtain shaped sheets of flat sheet.

LASER CUTTING

Machinery for processing metal pipes of different shapes and sections.The tube laser allows precise and quality operations: cutting, drilling, and sectioning for inserts.

TUBES BENDER

Machinery able to bend tubes and rods of various sizes. This process allows the production of structures with high quality and precise curvatures in mass production.

WELDING

Manual and robotic welding to build structures of different sizes and design.

GALVANIC

The galvanic process involves immersing the metal piece to be treated in a series of baths.
First the piece is degreased and cleaned perfectly.
After that, two electrodes are immersed in the tank that constitutes the galvanic bath,
containing an aqueous solution of the salt of the metal to be deposited, to which an electrical potential difference is applied.
The main bath is that of the electrolytic nickel solution. Here a layer of nickel is deposited on the piece which makes the metal surface as uniform as possible and protects it from corrosion.
After a further washing, the electrolytic solution of chromium or other metals is immersed in the tank which gives the typical aesthetic appearance of the metal itself (chrome, black chrome, ruthenium, gold, copper…).

COATING

Painting is a coating treatment that creates a protective barrier between the surface and the atmosphere.
Its function is to protect the artifact and to represent an aesthetic finish. Liquid painting can be used for multiple surfaces, powder coating is reserved for metals.
Drying the paint in the oven optimizes drying, improving performance. Then they pass into an oven at 140°-180°C where the paint first melts and then polymerizes forming an adherent film. This painting allows to obtain remarkable aesthetic, visual and tactile effects.

PLASTIC INJECTION

Injection molding is an industrial production process in which a plastic material is melted and injected through a high-pressure press into a closed mold, which is opened after the solidification of the product. This technology is particularly suitable for high production volumes. The thicknesses and finishes that the product must have are established during the mold design phase.
