Product Name: Vacuum Calibration Extruder of Black HDPE Protective Jacket Pipe for Pre-Insulated Pipe Model NO.: PE-960/1680 Computerized: Computerized Automation: Automatic Exhaust: Don't Exhaust Screw Channel Structure: Deep Screw Engagement System: Full Intermeshing Screw: Single-Screw Assembly Structure: Integral Type Extruder Feeding Mode: One Feed Product Type: Extrusion Molding Machine Plastic Processed: PE Type: Pipe Extruder Pipe Diameter: 960-1680mm Raw Material: PE Producing Method: Vacuum Calibrating Method Trademark: HSD Transport Package: Standard Export Packing Specification: PIPE DIAMETER: 960-1680MM Origin: Qingdao, China HS Code: 8477209000 Product Description Vacuum Calibration Extruder of Black HDPE protective Jacket Pipe for Pre-Insulated PipeIt is high-efficiency equipment with high speed and energy savingfor producing HDPE pipe used as a protective cover of PU foam thermal Pre-insulatedPipe.Itis small in size,easy to operate with the automatic control system and has long service life.Production line composition:-1set Vacuum loader-1set Hopper dryer-1set High-efficiency single screw extruder-1set Vacuum calibration table-1set Water spraying tank-1set Hauling machine-1set Cutting machine-1set Stacker---Pipe Usage: outer casing of thermal insulating pipe, which is widely used in central heating, oil, gas and other industrial areas.---Pipe/jacket diameter range: 110-1680mmMachine Advantages---High-efficiency extruder gives larger output, stable performance.---Pipe wall is average and smooth, to reduce waste of raw material, and pipe thickness is adjustable.---No need trim edge, once forming.---High degree of automation, can be operated by one person, saving labor costs.1. High-efficiency single screw extruder---Single screw is with barrier & mixing head; new model barrel with slotting (channel), Both make the security of good jellification, large output and stable performance.2.Die-HeadDie-head is mainly composed of mandril, neck mold, spiral body, cover, die-head body, bolts, and heating rings. The inside surface touching with plastic materials is polished and chrome plated to ensure plastic materials flow smoothly and to ensure no rusting. The uniformity of pipe wall thickness can be adjusted by bolts. The copper calibrating sleeve fixed in die-head is mainly used to cool down the fresh pipe and to calibrate the pipe outer diameter.3.Vacuum CalibrationTankVacuum calibrationtank is mainly composed of a frame, stainless steel tank, vacuum system, spray cooling system, position adjustment device. The vacuum pump exhausts the air from the sealed tank to pressurize the fresh pipe cling to calibrating copper sleeve and to calibratethe outer diameter. Spray nozzles spray cooling water from all directions on the pipe surface to cool down the pipe promptly.4.Caterpillar Haul-off MachineHaul-off machine is mainly composed of driving device, caterpillar, clamping structure, adjusting system, side plateand foundationbed. Haul-off caterpillars aredrivenbyAC motorwith frequency conversioncontrol to adapt to different extrusion speed.Automatic length measuring device realizescutting at a set length.5. No-Dust CutterIt adopts the blade punching principle to realize no-dust cutting. It is mainly composed of cutting devices, clamping devices, structure synchronous movement device and frames.6.ControlsystemThe complete line could be controlled by PLC, with good human-machine interface, all technical parameters could be set and indicated by touching the screen. The controlling system can bedesigned according to customers'requirements.7.Discharging frameThe table surface is made of stainless steel. It adopts pneumatic overturn and discharging automatically.Overseas clients
