Abstract

The object, in a device and a method for separating a shaped substrate from a stamping tool, is to make demolding more functionally reliable and to substantially prevent damage to expensive components. A closeable chamber, the mutually moveable chamber parts of which are the support for the stamping tool and for the shapeable substrate, contains a substrate holder which, when the chamber is closed, fixes. the substrate to its support outside the stamping area, with the result that the substrate is detached from the stamping tool when the chamber is opened. The device and method can be used for the production of microengineered components.
