Aluminum Tile Trim Production Processes:
Check our production processes and see how it happens in our factory for your products.
From raw materials to delivery, we take quality as our life.
No accept NG product, No produce NG product, No pass NG product.
Melting
The main raw material AL99.70 or higher quality aluminum ingots (GB / T1196),add Aluminum-Silicon alloy ingots and magnesium ingots for heating and melting, the melting temperature is 730 ℃ ~ 750 ℃, stirring, refining, slagging, etc.
Casting
Adopt the same level of the hot top casting process and use different molds to produce aluminum billets of different sizes.
Extrusion
The aluminum billets are heated to about 450 ° C, using an extrusion die, extruding various profiles with an aluminum extrusion machine, and quickly air-cooled or water-cooled, straightened, sawed and loaded them into the frame.
Aging
Adopt 190 ℃ ~ 195 ℃ for about 3.5 hours, and then use the forced air cooling process.
Polishing
Mechanical polishing for mirror effect, with certificated 6463 alloy aluminum billets, polish tile trim profiles with aluminum profile polishing machine. Tile trim profiles will be mirror look like after the mechanical polishing.
Brushing
Brush the pattern for the decoration, aluminum tile trim profiles will be brushed through aluminum profile brushing machine for hair line effect, the brushing effect can be heavy and light according to the request.
Anodizing (coloring)
The aluminum profile substrate is used as the anode and placed in the electrolyte to energize. The anode generates oxygen atoms and oxygen atoms have strong oxidizability. A layer of Al2O3 protective layer with excellent performance is formed on the surface of the aluminum substrate. Metal ions (nickel ions, stannous ions) are filled into the Al2O3 protective layer, so that the anodizing film shows different colors.
Powder Coating
Mill finish aluminum profile material is pre-treated by chromizing and powdered by electrostatic spraying. Curing: Bake the coated aluminum profile at 200 ° C for 10 minutes.
