Czochralski Crystal Puller
A machine used to produce monocrystalline silicon boules by pulling a seed crystal from molten silicon in a controlled temperature environment. It is classified under 8419.39.00 as other industrial dryers because the process involves controlled heating and cooling essential for crystal formation, which is a temperature-change treatment of materials.
