Plastic Sheet Extrusion Machine

The Jiuyimachine Plastic Sheet Extrusion Machine is an industrial processing line for continuous conversion of thermoplastic resins (PP, PE, ABS, HIPS, PC, PMMA) into uniform flat sheets. Built under ISO9001 and CE standards, the system integrates a single or twin-screw extruder, a coat-hanger T-die, a three-roll vertical or inclined calendering stack, a cooling bracket, a trimming unit, a haul-off, and an automated cross-cut saw or winder. It processes virgin, regrind, and heavily filled masterbatches under multi-shift production cycles.

Melt Homogeneity: Barrier-type screw geometries combined with multi-zone barrel heating prevent local polymer degradation and eliminate surging.
Structural Rigidity: Annealed steel frames absorb gearbox vibrations, maintaining alignment between the extruder discharge and the roll nip under high-torque loads.
Energy Efficiency: Inverter-controlled Siemens/ABB main drives paired with ceramic infrared heaters reduce electrical draw per kilogram processed.
Line Synchronization: PLC-controlled master architecture links line speed across the extruder, calender, haul-off, and cutter to prevent web tension fluctuation.

Refrigerator Liners: HIPS and ABS co-extrusion for inner door panels and thermal-formed liners.
Packaging & Boxes: PP and HDPE sheets for foldable turnover boxes and industrial pallet pads.
Signage & Glazing: PC and PMMA solid sheets for light boxes and optical protective shields.
Geotechnical Membranes: Heavy-gauge HDPE sheets for landfill lining and tunnel waterproofing.

Co-Extrusion Integration: Satellite extruders added for functional skin layers, UV caps, or recycled cores (A-B-A).
Specialized T-Dies: Adjustable lip geometries and internal choke bars for high-viscosity or ultra-wide webs.
Temperature Control Units: Dedicated multi-circuit oil chillers and heaters matching specific roll thermal demands.
Downstream Automation: Automatic width-adjustment slitters, sheet stackers, or heavy-duty turret winders.

Barrels: Forged from 38CrMoALA alloy steel, deep-gun drilled, quenched, and plasma-nitrided to HV950 hardness with 0.5 - 0.8 mm case depth.
Gearboxes: Hardened helical gears (20CrMnTi) carburized, ground to DIN class 6, and bench-tested under full load for 4 hours.
Rolls: Forged alloy steel, induction-hardened, precision ground, hard chrome-plated (0.08 mm), and dynamically balanced to G2.5.
Electrics: Schneider contactors, Siemens PLCs, and Omron temperature controllers wired to CE standards.
FAT: 72-hour dry and wet trial runs using customer-specified resins to output, melt pressure stability, and gauge tolerance. Jiuyimachine systems maintain an average operational uptime exceeding 95 percent across 30 countries.

Civil Layouts: Foundation drawings provided 4 weeks prior to shipment specifying concrete loads, anchor points, 3-phase power drops (380V/480V, 50/60Hz), cooling water flow rates, and air lines.
Commissioning: Mechanical and electrical engineers supervise machine positioning, optical alignment, and dry-cycle testing on-site.
Process Tuning: Resident engineers calibrate screw speed profiles, die bolt adjustments, and haul-off synchronization during initial resin startup.

Remote Diagnostics: Integrated VPN access modules allow remote parameter diagnosis and logic modification within 2 hours of notification.
Spare Parts: Critical wear items-heater bands, thermocouples, melt pressure transducers, and filter screens-stocked regionally for immediate dispatch.
Maintenance Tracking: Structured service intervals monitor gearbox oil degradation, screw clearance reduction, and bearing wear.
