rock wool stitching machine

The rock wool felt sewing machine is specialized sewing equipment for the further processing of rock wool products. It can continuously sew and reinforce rock wool felt with facing materials such as galvanized wire mesh, fiberglass cloth, and aluminum foil cloth. The equipment features a stable chain-stitch mechanism and supports single-sided or double-sided stitching. The resulting rock wool felt exhibits significantly enhanced tensile strength, resistance to airflow erosion, and resistance to delamination. It is widely used in high-temperature insulation applications such as industrial furnaces, thermal pipelines, and chemical tanks, offering easy installation and superior durability.
