Varnishing Machines

Varnishing Machines

Normally Impregnation is done in following manner

1. Insulating & mechanical properties of varnish.

2. Proper filling of gaps & voids.

To achieve & ensure the above two points during varnishing one should use the appropriate varnish & method depending on the geometry of the job. In the modern world the mainly resin impregnation method is used because of better mechanical & insulation strength of resin. Normally the resin & hardener mixture is used.


Normally Impregnation is done in following manner.

  • Metered quantity of varnishing machines is trickled on preheated rotating job.
  • Preheated rotating job is dipped in varnish.
  • By vacuum / pressure impregnation method.

Considering the geometry & quantity of the jobs required we have developed following types of varnishing machines. All machines are automatic with manual loading & unloading.

1. BATCH TYPE MACHINES

With heating by passing DC current through electrical winding and varnishing with trickle or dip n roll method.

2. INDEX TYPE MACHINES

Heating with Ceramic radiation heaters or hot air circulation and varnishing machines by trickle and/or dip n roll method.
