COMPLETE REBUILDING SERVICES
Rebuilding screws and relining barrels are more than just cost saving services. They often provide better wear resistance than when the components were new. Save money and bring your screw or barrel back to like new, or better condition, with Concor's remanufacturing services.
SCREW REBUILDING: Screw flights are repaired and rebuilt to SPI standards. A variety of hard surfacing materials are available. Broken drive end can be replaced and new hot ends can be installed should the tip threads be damaged. The screw’s compression ratio can be modified for specific processing applications. Mixing sections can be added or modified. Concor pioneered the process of rebuilding CPM 9V through-hardened tool steel screws in the '90's and we are experts in the process.
BARREL REBUILDING: Barrel relining eliminates the need for a new replacement barrel. Most barrels can be relined full length or partially relined. Several liner grades are available. Barrels can be modified to accept a bolt on end cap should the thread on design become a problem.
TIP REBUILDING: A tip assembly can have its sealing surfaces reground if the valve is through hardened and the check ring OD is still to size. In addition, the valve is cleaned and polished. There is a minimal cost associated with valve resurfacing.
END CAP REBUILDING: End caps can be "rebuilt" by inserting a through-hardened tool steel insert that provides a wear resistant surface on the ID angle and through hole.
