| Variable Valve Timing ComponentsThis group of variable valve timing components is an excellent
use of powder metal technology. The complicated geometry on all of
the parts can be formed with compacting tooling, and further
qualified with coining tooling to establish even tighter
tolerances.
- In almost all cases, these parts are ground to extremely
tight length, flatness, and parallelism tolerances, typically no
more than 20 micron
- Material selections are generally Iron-Copper or Iron-Nickel,
with heat treatment of critical areas
- With the exception of grinding and tapping stock for threaded
holes, there is zero material loss in the process for these
parts
|
 | Non-Magnetic CollarsThese non-magnetic collars are utilized in electronic locking
rear differential assemblies. The powder metal blank part is
reasonably simple, but when complete every surface has been
machined to an extremely tight tolerance.
- Austenitic stainless steel (303) is an excellent material
choice as it is both non-magnetic and stronger than other options
such as aluminum or brass
- Material loss during the machining process is relatively
minimal, since the blank size is tightly controlled in all
axes
- The collar is press fit into a housing on the OD interface
and has a bearing installed in the ID interface
|
 | Bearing Adjuster AssemblyThis Bearing Adjuster Assembly for a Front Wheel Drivetrain is
comprised of two powder metal blanks that are machined to final
configuration prior to assembly.
- The material utilized is a Chromium Steel (FL-5208), sintered
in a high temperature ceramic furnace
- The properties achieved are superior to those possible in
metal belt furnace at conventional temperatures, resulting in a
more robust assembly
- With the exception of the ID and OD threading, all of the
features on these two parts are created in the compacting
tooling, resulting in minimal machining waste
|
 | Four Wheel Drive Transfer CaseThese two components are utilized in a Four Wheel Drive Transfer
Case for light trucks, and work in concert to transfer power to the
front wheels once 4WD is engaged.
Fork Assembly
- An excellent candidate for the powder metal process, produced
off tools with no secondary operations
- The purchased pin is pressed in, providing a functional
component ready to install at the customer site
Connector
- A great candidate for powder metal as well, with the small
and large splines built into the compacting and coining
tools
- This part is produced to minimum density of 7.4 g/cm3 , and
heat treated for additional strength
