Device and method for production of dental molded parts

A method for production of dental molded parts from a polymerizable plastic, comprising the following steps:

• providing:
• a housing;
• a flask mounted to the housing including two shells that can be filled with polymerizable plastic, the flask having opposed sides, one of the opposed sides having an inlet opening, and the other of the opposed sides having a heatable top outer face,
• an injection device,
• a clamping device for pressing the shells firmly onto one another before injection of the polymerizable plastic, and
• a heating device mounted to the housing for heating the polymerizable plastic in the flask, the heating device and the flask being movable relative to each other;
• pressing the polymerizable plastic with the injection device into the flask through the inlet opening of the flask with a suitable injection pressure until the flask is filled while the flask is mounted to the housing;
• moving the heating device and the flask relative to one another while the flask is mounted to the housing after the flask is filled with the polymerizable plastic from a rest position where the flask is spaced away from the heating device to a heating position where the flask is in contact with the heating device, wherein the heating device encloses the heatable top outer face of the flask while the flask is in contact with the heating device and has a shape that matches a shape of the heatable top outer face;
• and
• heating the flask with the heating device when the flask is in the heating position to cause the polymerizable plastic within the flask to polymerize by heat radiation.
