3. Electroforming bars
3.1. Prepare the bars as described in the manual on
dental procedures.
3.2. Assembling the AGC MicroVision bar fork
The AGC MicroVision bar fork is a universal fork
suitable for any size of bar. The bar is connected to the
AGC bar fork.
The AGC bar fork connects positions 6, 7 and 8 of the
AGC MicroVision electroforming head ensuring
adequate stability and the current required.
Use a 1.2 mm carbide twist drill to drill a 3 - 4 mm long
channel in the base. Glue the AGC MicroVision bar fork
into the hole with a small amount of contact
adhesive (Loctite
®
).
Be sure to remove any excess glue since this could
have an insulating effect. The recommended
contact adhesive (Loctite
®
) is a special adhesive for
stainless steel, so please do not use any other.
3.3. Applying AGC Switch conductive silver lacquer
Clean the surface to be electroformed with compressed
air to ensure it is free of loose plaster and pattern resin
particles and degrease thoroughly with AGC degreaser
before applying AGC conductive silver lacquer.
Shake the AGC Switch conductive silver lacquer
well.
Apply the AGC Switch conductive silver lacquer evenly
up to the end of the milled surface or shoulder, making
a sufficiently wide (4 mm) connection to the contact
rod. Cover the AGC MicroVision contact rod completely
right up to the shrink-fit tubing.
About 1-2 mm of the alveolar ridge can also be electro-
formed to achieve a neat junction between the bar
sleeve and the plastic. To do this, apply the conductive
silver lacquer 1-2 mm over the alveolar ridge.
