The Jinwei Machinery developed PP+stone powder eco-friendly sheet material production line uses a three-extruder three or four-layer co-extrusion method, featuring Jinwei's newly designed PP+stone powder exhaust screw structure. It is controlled by a PLC computer and equipped with an automatic thickness gauge for detection, effectively utilizing the stone powder ratio. This not only reduces the raw material cost of the sheet material but also ensures its comprehensive physical properties and subsequent processability. The production line's capacity index reaches an optimal state, making it one of the most advanced sheet material units in the domestic market.
