electroform การใช้

Because aluminum can easily be chemically dissolved, a complex electroform can be produced with near exactness.
In order to facilitate the removal of the electroform from the mandrel, a mandrel is often made of aluminum.
The " father " is then used as a mandrel to electroform a positive disc known as a " mother ".
In most cases multiple copies are required and these can be formed by electroform using the master lens array as a mandrel.
In cases where hundreds of stampers may be required, the DMM disc is often used as a mandrel to electroform a master and mother, from which many stampers are then made.
