This UPVC Double Wall Corrugated Pipe Extrusion Line is the latest study achievement in the plastic in the plastic extrusion field. This extrusion line is suitable for the high speed extrusion of UPVC material. UPVC Double Wall Corrugated Pipe Extrusion Line adopts one conical twin screw extruder directly extruding and forming technology, human-machine interface control system. It makes high automation degree, reliable quality and stable production become true. And this Corrugated Pipe production line wins our home and abroad customers’ good reputation.
Extruder: High speed and efficiency conical twin screw extruder is specially designed for extrude PVC material, equipped with forced fixed-quantity feeding system, automatic temperature control system, vacuum exhaust system and automatic speed control system. This structure assures accurate controlling for the material temperature, plasticization stability and greatly improving corrugated pipe quality.

Corrugator: Corrugator is adopted horizontal structure with shuttle type transmission, SEIMENS control system, airtight water cooling system and vacuumizing forming, which assured very quick cooling and high output in production process. Professionally designed and fine made auxiliary equipments make the complete line running steadily.
Die head: it is composite die head and made of made of 40Cr, plating chrome and polishing. This die head makes the inner and outer layer wall thickness even and forming stability.
Mold blocks: Double Wall Corrugated Pipe forming molds which are formed by special aluminum alloy material through precision casting. They have high precision and strength, and excellent heat dissipation.
Cutting machine: High-strength alloy steel blade, Rotary cutting, smooth pipe incision, dustless cutting. The tracking device makes the cutting location precision. Germany SIEMENS professional PLC programmed controlling system makes operation easy and sensitive.
Control system: it adopts SIEMENS professional PLC control system, 15 "large color touch screen human-machine interface, high automation, reliable running, easy operation, remote communication function which can realize remote fault diagnosis and rule out the possibility.
