There are three types of remanufacturing activities. each
with different operational challenges.
Remanufacturing without identity loss with this-method, a
current machine is built on yesterday’s base, receiving all of the
enhancements, expected life and warranty of a new machine. The physical
structure (the chassis or frame) is inspected for soundness. The whole product
is refurbished and critical modules are overhauled, upgraded or replaced. If
there are defects in the original design, they are eliminated. This is the case
for customized remanufacturing of machine tools-airplanes, computer mainframes,
large medical equipment and other capital goods. Because of its uniqueness,
this product recovery is characterized as a project.
Remanufacturing by recoating of worn engine parts; many
engine parts, components are large and expensive and after a period of use
become worn. An example of such a part is the engine block, in particular the
cylinder engine bores, which must withstand explosions during piston firing.
Instead of disposing of large engine blocks, remanufacturing has resulted in
re-use of the parts by coating them with plasma transferred wire arc spraying
(PTWA) Caterpillar known for manufacturing very large industrial trucks and
machinery has started such remanufacturing programs of equipment parts using
PTWA, resulting in a greener environment. Remanufacturing by recoating of parts
is very popular in the aircraft field, the geothermal pipe field and the
automotive engine field.
Repetitive remanufacturing without identity loss; in this
method, there is the additional challenge of scheduling the sequence of
dependent processes and identifying the location of inventory buffers. There is
a fine line between repetitive remanufacturing without loss of identity and
product overhaul. Again, the critical difference is that remanufacturing is a
complete process. The final output has a like-new appearance and is covered by
a warranty comparable to that of a new product.
