Industry Applications
PVC Pipe Extrusion
Used in the production of rigid PVC pipes for water supply, drainage, irrigation, and electrical conduit applications. Our conical twin screw barrels provide gentle, low-shear plastication that prevents thermal degradation of sensitive PVC compounds, ensuring smooth pipe surfaces, consistent wall thickness, and high output efficiency.
WPC Profile Extrusion
Applied in manufacturing wood-plastic composite (WPC) decking, fencing, railing, and window profiles. Our bimetallic screw and barrel assemblies offer exceptional abrasion resistance against wood fibers and mineral fillers, delivering homogeneous melt quality, reduced downtime, and extended component service life.
Sheet & Foam Board Extrusion
Commonly used in the production of PVC sheet, foam board (e.g., Celuka or free-foam), and rigid film. Our conical twin screw systems ensure uniform melt temperature and consistent thickness control, delivering smooth surface finish and dimensional stability for construction signage, interior decoration panels, and packaging sheets.
