Seamless pipe & seam pipe-Indirect &direct extrusion press
 

These days many new inquirers want an extrusion press to produce aluminum pipe or aluminum tube or copper pipe or copper tube. My first question to asked them: "will you produce seamless pipe or seam pipe? " Some of them were impatient.

Becauseseamless aluminum/copper pipes or seamless  aluminum/ copper tubes are applied to industry, they can stand high pressure, like the pipe of refrigerator, air conditioning, etc. It need more strict extrusion process to control the quality. So these pipe need to use the indirect extrusion press to produce them. Currently China indirect technology is not perfect enough, after use a certain time, the mandrel may deviate, it will influence the extrusion quality. If you want to use our direct extrusion press, you need to make an extra process to drill the hole into the billet, it can work for it.

For the quenching system, some aluminum pipe or aluminum tube will adopts 6061 alloy, so the quenching system will adopt water quenching.

And the aging process of 6061alloy also is different from 6063 alloy, these need to be pay attention on it.
