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.

GALVANICA

Il processo galvanico prevede l’immersione del pezzo metallico da trattare in una serie di bagni.
Dapprima il pezzo viene sgrassato e pulito perfettamente.
Successivamente nella vasca che costituisce il bagno galvanico, contenente una soluzione acquosa del sale del metallo da depositare, sono immersi due elettrodi ai quali viene applicata una differenza di potenziale elettrico. Il bagno principale è quello della soluzione elettrolitica di nichel. Qui si deposita sul pezzo uno strato di nichel che uniforma il più possibile la superficie metallica e la protegge dalla corrosione. Dopo un ulteriore lavaggio avviene l’immersione nella vasca della soluzione elettrolitica del cromo o di altri metalli che conferiscono l’aspetto estetico tipico del metallo stesso (cromo, cromo nero, rutenio, oro, rame..).

COATING

POWDER COATING
Powder coating is a process of painting metal surfaces with an organic film. It’s made for a practical and resistant decoration and against corrosion and aggressive agents. The pieces being processed are covered with a powder coating based on synthetic resins adhered by electrostatic effect. Then they pass into an oven at 140°-180°C where the paint first melts and then polymerizes forming an adherent film.

LIQUID PAINTING
Liquid painting is a coating treatment that creates a protective barrier between the surface and the atmosphere, and which give a finishing characterized by unique effects.
Liquid painting can be used for special surfaces, metallic or non-metallic and allows to obtain a high quality design. The oven temperature of 60°-80°C degrees guarantees the complete drying of the film.

LASER CUTTING

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.

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.
