Production Process
-Pre-Treatment:
All the pipes are treated by sandblasting to clean rust in order to make pipe surface to be rough, easy for paint spraying.
-Pipe Cutting:
After the treatment, the pipes are cut into fixed length.
-End Boring:
It is a process to enlarge inner diameter of pipes. By using automatic double end boring machine, roller pipe can be treated coaxially to make sure perfect fit with bearing house.
-Bearing House Welding:
Two bearing houses are pressed into the pipe, and welded together with the pipe.
-Painting & Surface Treatment:
Electrostatic painting, or customized painting demands.
-Shaft Cutting:
The shafts are cut into fixed length.
-Flat Milling:
The shaft is treated at two ends, making into the flat ends.
-Final Assembling:
The pipe and the shaft are press-fitted together with bearing, seal, seal cover, circlip, making into a steel tube conveyor roller with the automatic press assembling machine.
Packaging
Conveyor rollers are packed with plastic cloth, or plywood box or as per your specific requirements.
