The conical twin-screw barrel is specially designed for the production of WPC boards, doors, foam boards, SPC flooring, and all PVC products. The advanced bimetallic and SKD inner lining technology can handle both virgin and recycled materials, with the raw material capable of incorporating 5%–300% calcium carbonate. In environments with any calcium carbonate ratio, we have extended the screw lifespan by over 30%.
SKD inner lining technology: Installed in different areas as needed to reduce internal wear of the barrel.
Tungsten carbide alloy combined with ceramic dual-layer alloy coating technology in the discharge and mixing zones, focusing on protecting the high-wear areas of the screw, extending its service life.
Various structural designs for high calcium, medium calcium, and low calcium: Due to the diversity of PVC raw materials, each company uses different calcium carbonate ratios, which vary greatly. We offer over 10 different screw structural designs to accommodate varying raw material ratios, improving output and plasticizing efficiency.
