Incoming solenoids are inspected for signs of cracking or excessive wear.  If they are candidates for rebuild, they are fully disassembled and component tolerances are checked.

Solenoid windings are removed from the bobbins and the bobbins are replaced with vacuum/pressure impregnated coils wound on non-conductive bobbins. with Welbor�s proprietary encapsulation process.  Internal plungers and shafts are discarded and replaced with special magnetic alloys that improve pull-in performance, and provide better straightness and fit.

Re-assembled solenoids are tested to original specifications using the original manufacturer�s hardware before shipment.  Solenoids are tested for both electrical and mechanical properties and a record of their performance is included with each solenoid.
