packing
Home protective film is made when profiles coming through the machine. heat shrink film is packed by hand, then to make it tight through the machine.
wood grain
Home packing with wooden texture paper and ready for heat transfer. wood grain vaccum machine will transfer the wooden texture from paper to aluminum profile surface in stove at high temperature.
powder coating
Home powder coating thickness is 40-120um, which is durable for different weather condition.https://www.intop-alu.com/wp-content/uploads/2023/05/video_1714028485.mp4 we not only have horizontal coating lines, but also have vertical coating lines powder coating colors are various for customer choices
anodizing
Home anodizing is the main surface treatment for aluminum profiles, national standard coating thickness is AA10https://www.intop-alu.com/wp-content/uploads/2023/05/VID_20240516_105330-1.mp4 coloring is made like champagne, bronze, black by sinking the aluminum profiles in tanks for minutes. sealing and drying is also important for lifetime, then for packaging
polishing
Home polishing can remove the extrusion lines and get a bright mirror surface by mechanical forces some profiles for bathroom need chemical polishing after this processment
sand blasting
Home sand blasting will create matt surface and eliminate the extrusion lineshttps://www.intop-alu.com/wp-content/uploads/2023/05/video_1714029532.mp4 sand blasting is a pre-treatment before anodizing or powder coating
aging
Home Aging and curing will make the profiles has better physical strength and hardness aging stove will keep the temperature at about 300 degree for hours
saw cutting
Home cut the aluminum profiles at the demanded length at 3m, 5.8m or 6mhttps://www.intop-alu.com/wp-content/uploads/2023/05/VID_20240418_164826.mp4 many aluminum chips when cutting profiles
stretching
Home stretching machine clamp the aluminum profile end then pull at a pressure stretching is a necessary process to pull the profile straight
extrusion
Home shear the log for the extrusionhttps://www.intop-alu.com/wp-content/uploads/2023/05/VID_20240418_164223.mp4 extrusion machine supply the pressure and force the liquid aluminum going through the mould profiles come out from the output, the puller will take it to the other end of the table move the profiles waiting for stretching
