About Us
The aluminum liquid distribution bag produced by Shandong Ningjin Bohan Machinery Co., Ltd. has been specially selected, designed and woven to ensure that the yarn and mesh of the distribution bag are uniform and prevent the pressure or flattening caused by the contact Deformation, especially suitable for splitting and filtering of molten aluminum in large furnace slabs. The company has passed ISO9001 certification. Each batch of products is tested to check its burning loss, stiffness and mesh size to ensure the stability of product quality.
