The specially designed DKM basket die head and spiral die head for the DKM series single screw extruder, fits well with the DKM high speed vacuum calibrator and guarantees the high output with excellent article quality. The max producible pipe diameter isΦ1600mm. Regardless of material viscosity variation, widely applicable for HDPE/MDPE, PERT, PP/PP-R, PB, PS/ABS and HMW-PE pipe production, with reliable processing property. High output but rather low pressure drop and melt temperature. Small pipe stress due to the low melting pressure and temperature. Capacious and smooth runner reduces the pipe stress to the minimum. High quality ceramic heater with longer service life. Pipe with scratch-free smooth surface finishing.
