Paper tube or cylinder liners are cast exclusively centrifugal method for obtaining controlled brain-grain material
in the casting. Depending on the type of application requester, we are able to influence the so-called "pearl structure"
controlled "C" (carbon). This method of drainage, chemical controlled mass, we get a composition that can be compared
to ensembles of many leading manufacturers of cylinder bores of all kinds. After the first, rough machining lathes,
all of our shirts go to the first heat treatment at a later date, after the second heat treatment given the pre-defined
rigidity (RC), to say the paper tube marine engines "SULCER" or "PIELSTICK" warranty for the paper tube of 6000 hours.
