Czochralski Crystal Puller from Japan
A machine used to grow monocrystalline silicon boules by slowly pulling a seed crystal from molten silicon, involving precise temperature control for crystallization. Classified under HTS 8419.39.0280 as industrial drying equipment due to the heating and controlled cooling processes essential for crystal formation. This equipment is critical for semiconductor wafer production.
