ABSTRACT:
An improved method for producing a ceramic resistor is disclosed. The method comprises the steps of charging ceramic batch into a longitudinally extending die, pressing the batch in the die between opposing plungers, removing one plunger from the die, ejecting the blank by moving the other plunger relative to the blank and firing the blank. The improvement constitutes imparting rotational motion to the removable plunger as applied pressure thereon is being released to remove the plunger from the die, whereby the surface of the plunger in contact with the blank separates therefrom without sticking.
