Furnace VARIO PRESS 330 .e ZR

The ADVANCED PRESS™ process ensures a homogeneous temperature distribution from the thermocouple of the press furnace to the interior of the press muffle and guarantees the ideal temperature range when pressing lithium disilicate. As a result, this technology ensures perfect surfaces, minimal reaction layers and extremely short pressing times.

The exceptional software and lift technology enable a linear cooling process in TTC mode: In this program, the user determines the freely selectable cooling rate after firing. Cracks in the ceramic or the dreaded “chipping” are a thing of the past.

The electronically controlled pressing pressure control recognizes the required forces during the work process depending on the geometry of the pressed objects. With different volumes or wall thicknesses, the VARIOPRESS 330 automatically and dynamically regulates the pressure during the entire work process. Premature termination of the pressing with resulting defects in the pressed objects are almost impossible.

A virtual sensor calculates the lift position at short intervals depending on the current temperature inside the firing chamber for a constant temperature of approx. 150°C over the entire surface of the tray. This process prevents the ceramic from cracking or blistering.
