Sapphire Crystal Growth Furnace CZ method Czochralski Furnace produces high quality sapphire crystals

ZMSH's CZ Puller furnaces are available in a wide range of sizes, heating power elements and strengths. According to the process requirements, the heating technology of the direct-drawn furnace can be inductive or resistive. Crucible sizes up to 400 mm in diameter and operating temperatures up to 2300°C.

The pull-through furnaces are equipped with precise and stable pull-out heads with conversion rates ranging from 0.01 to 100 mm/hour. Intuitive, user-friendly crystal pulling software for complete monitoring and control of the growth process. In this way, after dipping into the seed, the crystal can be grown automatically, and the seed growth is based on the predefined crystal geometry created by the user in the software-specific geometry definition window. The variety of Czochra furnace designs makes it ideal for use in laboratories, universities and research and development centers.
