CTPR has its own foundry to produce highest quality gray and nodular cast iron piston ring blanks.Iron melting is done by an induction furnace for proper control of temperature. High-tech equipment including metallurgical laboratory with spectrometers that are used to control composition.
Our engineers use computer-based programs to design products according to the operation plans and technical drawings. All production operations are prepared following ISO and DIN Standards. Custom-tailored production according to drawings of customers is also within our capabilty.
CTPR always uses cutting-edge technology machines for the best possible machining tolerances. Our machines have technologies such as CNC , automatic loading/unloading, automatic measuring and compensation for constant quality production. The periphery of all rings is lapped by special machines for r
PHOSPHATING ( P ) : PHOSPHATE COATING ON ALL SURFACES With phosphating, crystalline phosphates are deposited on all surfaces of the piston rings except chrome – plated areas. The phosphate layer has a thickness of 0.002 – 0.005 mm. and improves the running in behaviour of the piston ring by increas
