On the basis of many years design and production experience, we absorbed in the Europen advanced technlogy of pipe industry, and have developed this integrated multifunctional co-extrusion production line. This complete line from extruder to the down-stream line, from the raw material to the finished product, every steps is automation. The compound co-extrusion standard series from Ф 10 to Ф 630. The spiral distribution type or basket distribution type spindle assure enough flow space and time for the melt material with a low temperature, which will assure the finished pipe with smaller innerstress and smooth surface. The flexibile design is suitable for PP ,PE ,PP-R,EVOH,PA. ABS, various kinds of polyolefin material for co- extrusion two layers, three layers, four ayers and five layers. Application
