Title
Steatite Chip Pressing
Description

3. Granulated steatite is compressed into substrate form by high-speed presses. These machines automatically fill the die cavity with a predetermined amount of powder and under regulated pressure (1 to 40 tons, depending on model) press a punch into the cavity to form the substrate. A complete pressing cycle takes only 1 second. During the pressing operations, holes for the terminal pins are formed. Substrates are then placed on special trays for firing.
