With over 25 years of experience in mechanical machining
We, S.C. ELUR IMPEX S.R.L., have become remarked by the quality of new or refurbished products, especially for injection/extrusion plastics machines (screws, barrels, flanges, end caps, nozzles, anti-return valves, air ring systems, etc.).
Rebuilding a screw is warranted when its wear is normal, if it only affects the top of the thread, not the bottom or sides. The repair involves reloading the top of the thread with a stellite alloy with a hardness of 52-56 HRC. After the load has been corrected, the screw is nitrated.
REBUILDING THE CYLINDERS
It consists of rehoning the cylinder by fastening to the maximum of wear. The screw must be recharged to the new dimension as well, and the anti-return valve must be replaced (in the case of injection assemblies). After reconditioning the cylinder is nitrated (when the material is known).
REBUILDING THE ANTI-RETURN VALVE (TORPEDO)
Anti-return valves are reconditioning by weld loading of plunger wings with stellite and possibly replacing bushings and/or valve seats.
