The company has innovatively developed a fully needle punched carbon/charcoal crucible holder using carbon fiber integral imitation needle punching technology, which not only shortens the needle punching cycle, but also solves the problem of central over piercing, ensuring the uniformity and controllability of needle punching. The fully needle punched product enhances the interlayer strength of the prefabricated body, allowing the processed crucible holder to maintain excellent stability and durability in alternating cold and hot environments, extending the average service life.
