For decades, our company has been digging in the plastic pipe extrusion field. Oriented by the customers’needs, our company has developed plastic pipe extrusion equipments with complete categories and specifications through the cooperation with the German company, Graewe, and all of these have accum......
Read MoreThe production process of large diameter HDPE winding pipe is unique and novel, which can meet the production needs of different products. It adopts a unique hot winding welding process, and can produce products with different inner diameters and different structural forms on the same production lin......
Read MoreDue to the limitations of materials and structures, simple wall plastic pipes are mainly used in small-diameter pipes, while large-diameter pipes mainly use various structural wall plastic pipes, such as double wall corrugated pipe, clara winding pipe and hollow wall winding pipe. Among all kinds of......
Read MoreDefects in extruded products occur predominantly due to friction and non-homogeneous material flow. Further, temperature variations across the billet during hot extrusion can also lead to inhomogeneous deformation. Three types of defects are prominent in extrusion. They are: extrusion defect, surfac......
Read MoreDue to the high brittleness, low melt strength and poor processing fluidity of UPVC materials, modifiers usually need to be added in the processing to improve the fluidity of UPVC, melt strength and material toughness. ACR or chlorinated polyethylene (CPE) and MBS are the modifiers of UPVC.
