Czochralski Crystal Puller from Japan

A Czochralski crystal puller is specialized machinery used to produce extremely pure monocrystalline silicon boules by pulling a seed crystal from molten silicon. These boules are then sliced into wafers for semiconductor fabrication. Classified under HTS 8442.30.0150 as other machinery for preparing printing components, though primarily serving semiconductor boule preparation analogous to printing plate production.
