Heating container for preventing leakage of high-temperature metal material and manufacturing method thereof

Abstract

The invention relates to a heating container for preventing leakage of a high-temperature metal material and a manufacturing method thereof. The heating container comprises an internal heating container for containing a metal material, an external heating container for accepting the heating of a heating device, and an upper cover with an air hole for escaping of the metal material after evaporation, wherein the internal heating container is completely contained in the external heating container, and is fixed at a position relative to the external heating container; a gap is formed between the side wall of the internal heating container and the side wall of the external heating container; the upper cover is fixed above the internal heating container and the external heating container, and is used for covering openings of the internal heating container and the external heating container. The invention also provides the manufacturing method of the heating container. By adopting the heating container disclosed by the invention, the problems of abnormal material loss and production schedule interruption caused by cracks of the heating container generated in daily use can be solved; the continuous and stable operation cycle of the heating device can be effectively prolonged, and the product quality can be ensured.

Description

technical field [0001] The invention relates to a heating container, in particular to a heating container for preventing leakage of high-temperature metal materials and a manufacturing method thereof. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) has the advantages of all solid state, ultra-thin, no viewing angle limitation, fast response, room temperature operation, easy realization of flexible display and 3D display, etc., and is unanimously recognized as the mainstream technology of next-generation display. At present, the main method of OLED device production is heating evaporation coating, which mainly uses a heating container to heat the evaporation material in a vacuum environment, so that the sublimation or molten evaporation material is vaporized at a high temperature and deposited on a TFT structure or an anode. structure on the substrate. [0003] In the existing evaporation process, the mode of heating and evapor...
