It is a computer controlled lining technology using rotational movement of equipment along with sintering process. This process creates seamless lining with virtually uniform lining thickness from 500 microns to 6mm Roto lining of HDPE, PP, PVDF, HALAR , ETFE , FEP, PFA is available in natural, FDA or Antistatic Conductive fnish.
The parts to be processed are checked before being lined according to the construction guidelines DIN EN 14879-1. The radiuses have to be properly rounded off and welding seams have to be cleanly ground. No welding beads are allowed to remain.
Before the lining process, greasy or oily residues have to be removed, as these can influence the adhesion of the lining onto the carrier material.
In order to achieve adhesion, the parts are first sandblasted with highly purified aluminium oxide.
The components are fixed into a clamping device and filled with the appropriate material. The lining temperature and rotational speed are individually set.
Mechanical processing of the sealed surface.
The components are inspected visually for appearance, layer thickness, pore impermeability and, if necessary, electrical conductivity, and an inspection certificate 3.1 according to DIN EN 10204 is issued. All test procedures are documented.
