This sizing sleeve adopts high-density material with solid integral structure, resisting cracking, damage and deformation under long-term high-temperature operation.
Mirror polished inner wall prevents material adhesion, producing pipes free of scratches and pits with excellent surface finish.
Optimized spiral cooling channels deliver uniform heat conduction and high cooling efficiency, greatly boosting the output of extrusion lines.
CNC integrated precision machining ensures tiny dimensional tolerance, stable pipe outer diameter, perfect roundness and uniform wall thickness.
Wear-resistant and anti-corrosion surface treatment fits PVC, HDPE, ABS, PPR and other materials, extending long service life.
Customizable multiple calibers with easy disassembly and cleaning, perfectly matching all automatic plastic pipe extrusion mold production lines.
