Main Features:

Air shaft:

1. The air shaft introducing foreign advanced production equipment and fabrication technology,   using imported balloon, the shaft is casting by aluminum alloy, shaft body plating chromium, accurate assembly, convenient to use and long operate life. When used with my companys professional configuration of the air gun mouth filling gas, to make the shaft of off-axle apperance uniform expansion, thereby lock nitrogen-treated barrel, when unloading, press on deflated mouth to deflated, then nitrogen-treated barrel can be unloaded.

2.Performance and advantages: air shaft in practical applications, it has advantages of convenient operation, quick, without damage rolls etc.

3.Mechanically Expanded shafts were made of aluminum alloy or steel construction,all air expansion shaft we can according to customer's drawing.
