Smelt: Main raw material for above AL99.70 aluminum ingots (GB / T1196) add aluminum silicon alloy ingot, magnesium ingot heating melting, melting temperature between 730 ℃ ~ 750 ℃, to stir, refining, slag etc.
Casting: Uses at top casting process, using different mould, produce different diameter specifications of the aluminum rods.
Ingot homogenizing: Rapid cooling is 575 ℃ heat 6 hours.
Compression: Aluminum bar heated to 450 ℃, using the mould, with extrusion press all kinds of extruded aluminium profiles, and rapid air cooling or water cooling, straightening, cutting, frame.
Ageing: The 190 ℃ ~ 190 ℃ heat preservation 3.5 hours, then adopts the forced air cooling technology.
Anodic oxidation (color) : With aluminum base material for the anode, put in the electrolyte electricity, anode produce oxygen, oxygen atoms have strong oxidizing, iIn the aluminum base material surface generates a layer excellent performance of Al2O3 protective layer, coloring using electrolytic coloring process, the metal ions (nickel ion, stannous ions) to fill Al2O3 protective layer, made the oxide film showing different color.
Hole sealing: the Ni2 +, F - cold hole sealing technology.
Electrophoresis paint: after anodic oxidation (coloring) profile in the electrophoresis tank, electricity make acrylic resin adhesive on the surface of aluminium profiles.
Curing: the electrophoresis paint of profile at 180 + 20 ℃ temperature, drying curing for 30 minutes.
Powder spraying: aluminum substrate through before chromium processing, through the electrostatic spraying powder coatings.
To curing powder coatings profile baking at a temperature of 200 ℃ for 10 minutes.
Hob, wear, pressing: the article in the craft production heat insulation aluminium extrusion profiles, first produced aluminum extrusions with slot, with dedicated gear hobbing device on the slot opened a tooth of 0.5 ~ 1.0 mm deep. Article through nylon insulation PA66, GF, will feature two aluminum composite with pressing equipment together, issue the energy-saving performance of insulation aluminum production.
