The first order is jdl series parallel twin screw.The twin screw speed , high shear, strong hybrid advantage , make the material fully completed plasticizing mixing , because there is no head back, so that we can arrange for screw combination of different materials and flexible, achieve the best mixing. In order for the jdl series single screw extruder.Low speed characteristics of the deep groove screw provides processing environment of low shear, at the same time with the barrel cooling, prevent the plasticized material produce the phenomenon of thermal decomposition at high pressure extrusion ;is conducive to the realization of process different, to maximize the advantage of equipment , improve production efficiency; Suitable for processing all types of heat -sensitive materials , such as pvc, xlpe, low smoke halogen -free flame retardent cables, shielding material.
