Hot Pressing
TA&T has 30- and 600-ton vacuum hot presses that are available in sizes from 2” to 36” in diameter.
TA&T can adjust heating and pressure profiles to meet customer requirements as well as both circular and rectangular sizes using graphite inserts in larger graphite dies. If desired, TA&T can provide post processing steps including part density, hot isostatic pressing, grinding and polishing and optical property measurements in the case of transparent materials. The size and temperature capability of the presses are in the table below.
| Press | Max Temperature | Max. Die Size* |
|---|---|---|
| 30-ton | 1650°C | 5” diameter |
| 600-ton | 1650°C | 36” diameter |
