A Case History:

A DELICATE MATTER




 


Problem Solved

A manufacturer of electronic parts was faced with a very difficult assembly application.

The fragile stamped copper connectors were of exceptionally delicate design.

The Manufacturer had originally attempted to swage-form the small pins into two of the thin fingers of the piece with a pneumatic press but, unfortunately the amount of down-force required to form the pins pushed the heads off center and deformed the blanked contact parts; the rejection rate was unacceptable.

Taumel suggested that their Orbital process would use only a fraction of the press's operational force and could form the contact pins gently and incrementally.

A special jig was designed to hold the die-stamped copper contacts firmly and securely while recesses in its base kept the pins perfectly upright and straight during the forming process.

A standard off-the-shelf orbital forming tool could be used to form the heads of the inserted pins smoothly and safely over the blanked-out contact parts without deforming the assembly in the slightest degree
.

Taumel's approach eliminated both the deformation and the consequential high rejection-rate which the electronic parts Manufacturer had experienced previously.


This custom Fixture and Slider were designed especially to handle these delicate parts.
The tiny pins and the delicate stamped contact fingers are carefully protected
and accurately positioned during the Orbital Forming process.
This special equipment was designed and manufactured by Taumel to meet
the tight specifications necessary for this particular operation

Taumel's Orbital Forming has the advantage
that it accomplishes tasks by using much less
forming pressure than a conventional press.
