High Frequency Car Radiator Aluminum Tube Mill
I Description of car radiator aluminum tube mill
This machine is specially designed for producing below flat aluminum tubes used in car radiators. 
Tube rolling moulds are designed in quick-changeable cassette type. By changing this kind of cassette, other size flat aluminum tubes can be produced as well.
This machine can 100% replace those aluminum pipe mill from Schoeler Germany, Millmaster USA or Japan.
Production flow:
- Aluminum strip reel loading by vacuum absorber loading device (optional)
- Aluminum strip decoiling by active decoiler
- Aluminum strip feeding by synchronization feeder with buffer
- Pre-forming by pre-forming mould section
- Welding by solid-state high-frequency welder
- Squeezing by ceramic rollers
- Burr removing
- Size fixing by size-fixing mould section
- Cutting to length by non-stop flying saw cutter
II Main features of car radiator aluminum tube mill
- Special roller designing and adjusting technology for various aluminum tube forming.
- Max. production speed 150m/min
- High quality solid state high-frequency welder, less electric consumption, smaller internal burr
- Online cut-to-length, no need secondary processing
- Special cutting device, supper high speed cutting catching the whole line speed
300~375 cuts/min @400mm length
160~200 cuts/min @750mm length
120~150 cuts/min @1000mm length
40~50 cuts/min @3000mm length
20~25 cuts/min @6000mm length
