Automatic coating line for automobile aluminum wheel hub


coating process:
High - grade cars use aluminum alloy wheels nowadays . According to different requirements of the products , different technological methods are adopted .The main development trend of the global aluminum wheel is coating hub, bright surface wheel hub, polishing wheel hub, electroplating wheel hub and so on.。The main coating patterns are as follows:
low-end product :pretreatment →Metal paint coating→Mask varnish coating
medium-end product:pretreatment →Bottom powder coating→Metal paint coating→Mask varnish coating
high-end product:pretreatment →Bottom powder coating→Metal paint coating→Mask varnish coating→Bright powder coating
① Medium product coating:  pretreatment→Bottom powder coating→Coloring (silver, white)→Finish paint ( automatic electrostatic shield photo - coating )
② High - end product coating:  pretreatment→Bottom powder coating→Coloring (silver, white)→Finish paint ( automatic electrostatic shield photo - coating )→Bright powder coating(Powder cover light coating)
Mechanical transmission mode:
Two types of conveyance are generally adopted。Ordinary type suspension conveyor and common ground ring conveyor。The manipulator is used when the large quantity of transshipment is needed on the way, and the manual is used in the small batch.
1.Annular ground conveyor
The international popular aluminum wheel transmission, suitable for painting or powder, with automatic spraying can guarantee the product quality of spraying。The process layout is flexible and convenient。the drying room can adopt a multi - stroke drying chamber or a drying chamber which runs parallel to the wheel hub。
2.Open type suspension conveyer
The international fashionable aluminum hub transport mode is suitable for the pre treatment cleaning process. 2-3 pieces can be hung according to the different output. The cleaning effect is good. The sling is simple and applicable.
