Material:
The most common used aluminium alloys to produce profiles are alloys from the series 6xxx. The most used to produce aluminium profiles to construction are 6060 and 6063 with heat treatment T5. We also produce profiles with other alloys as 5xxx or 7xxx series according to the customer needs.
Treatment
The three more common heat treatments applied to aluminium profiles are:
T4: Tempered from the solution temperature by forced air, natural aging.
T5: Tempering treatment from the extrusion temperature using forced air, then artificial aging. It is the most common heat treatment on aluminum profiles to doors and windows profiles.
T6: Tempered from the solution temperature by water (under 40ºC) and artificial aging.
The followings are the most common surface treatments of our aluminum profiles.
Polished: is the process of creating a smooth and shiny surface by rubbing it or using a chemical action.
Anodized: is a characteristic aluminium coating, this method consist on increase the thickness of the natural oxide layer on the surface of aluminium parts, to obtain greater strength and durability components.
Powder coating: it can produce thicker coatings than conventional liquid coatings without running or sagging.
We also work with another coating methods such as electrophoresis paint or PVDF paint.
Advantages:
High comprehensive quality of products.
Extrusion molding can improve the structure and mechanical properties of aluminum. After quenching and aging, mechanical properties of longitudinal (extrusion direction) of extruded products are much higher than those of similar products produced by other processing methods. Compared with rolling, forging and other processing methods, extrusion products have high dimensional accuracy and good surface quality.
Wide range of products.
Extrusion can not only production profile is simple tube, rod, wire, and can also produce the section shape is very complex, solid and hollow profile products section along the length direction of the phase change and gradual change of variable cross-section profiles, many of the products in the shape of a cross section is beyond the forming of other plastic processing methods. The size range of extruded products is also very wide, ranging from the extra-large pipe and profile with a diameter of 500-1000mm to the ultra-small precision profile with the size of matchstick.
Simple process and less equipment investment.
Compared with pipe and profile production processes such as perforated rolling and groove rolling, extrusion molding has the advantages of short technological process, less equipment quantity and less investment.
