Featured Precision Extrusion Lines & Turnkey Downstream Units
Explore our custom-engineered extrusion platforms, designed for ultra-low wall-thickness variation, energy-conserving thermal control, and high linear output.
Comprehensive Engineering of Custom PE Straw Tube Extrusion Lines
Delivering micron-level dimensional stability through optimized screw shear dynamics, closed-loop vacuum calibration, and high-speed servo cutting synchronization.
Melt Plasticization & L/D Ratio
Precision polyolefin processing demands dedicated screw geometry. Our PE straw extrusion lines utilize a custom 30:1 to 33:1 L/D ratio barrel with barrier mixing flights. This mitigates polymer degradation, homogenizes melt temperatures across low-density (LDPE), high-density (HDPE), and linear low-density (LLDPE) feedstocks, and eliminates un-melted gels at extreme line speeds exceeding 300 m/min.
Thermal & Vacuum Sizing Dynamics
Constructed from anti-corrosion SS316 stainless steel, our dual-chamber vacuum calibration tanks feature high-precision water level and PID vacuum degree controllers. Variable speed circulating vortex pumps maintain laminar fluid contact along the forming sleeve, preventing ovality and wall collapse during sudden thermal shrinkage transitions.
Ultra-High-Speed Servo Cutting
Equipped with either rotary fly knives or brushless servo-driven guillotine cut-off heads, our downstream units produce burr-free, zero-dust square or angled bevel cuts. Integrated with dual-axis infrared sensors, cutting accuracy is kept within ±0.05 mm, fully compliant with high-speed automated packaging and medical insertion lines.
Localized Global Support & Regulatory Compliance
Ensuring that your tube manufacturing plant passes rigorous international food safety, medical hygiene, and electrical machinery audits seamlessly.
FDA & EU Food Contact Compliance
For drinking straws, confectionery applicator tubes, and liquid dispense tubes, contact material hygiene is paramount. All material-contacting zones across our barrels, feed throat liners, crossheads, die mandrels, and vacuum calibrators are machined from certified food-grade stainless steels and non-migratory lubricants conforming directly to US FDA 21 CFR 177.1520 and European Union Regulation (EU) No 10/2011.
CE Machinery & UL/CSA Electrical Standards
Export configurations come fully validated under European Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU, with complete dual-channel emergency stop circuits, pneumatic safety interlocking guards, and CE-marked components. For North American buyers, optional UL 508A-certified and CSA-standard electrical control cabinets are built with premium Schneider, Siemens, and Omron automation hardware.
Rapid Field Service & SLA Guarantees
Our specialized Global Service initiative guarantees remote telemetry diagnostic response within 2 hours and rapid on-site commissioning engineer dispatch across major manufacturing hubs in Southeast Asia, the Middle East, Europe, and the Americas. Comprehensive wear-part kits, including bimetallic screw tips, thermocouples, heater bands, and cut blades, are stocked for immediate international air shipment.
Cleanroom-Ready Architecture for Medical Straws & Catheter Tubing
When configured for cleanroom deployment (Class 10,000 / ISO Class 7), our extrusion lines utilize totally enclosed air-cooled AC servo drives, oil-free vacuum pumps, HEPA filtered positive-pressure cooling cabinets, and mirror-polished stainless frames to eliminate airborne particulates and cross-contamination.
The Strategic Advantage of China’s Precision Manufacturing Ecosystem
Capitalize on the world’s most agile industrial manufacturing cluster located in Jiangsu, combining advanced metallurgy, CNC fabrication, and unbeatable capital expenditure efficiencies.
16,000 m² Integrated Manufacturing Base
Situated in Haian, Nantong, Jiangsu, our state-of-the-art facility integrates raw alloy processing, 5-axis CNC machining centers, nitriding heat treatment furnaces, and synchronized assembly lines. Having all core manufacturing processes in-house gives us total oversight of metallurgy tolerances, surface roughness (Ra < 0.04 µm), and delivery schedule adherence.
Agile Vertical Component Sourcing
The Yangtze River Delta industrial belt enables rapid co-development with premium domestic and international Tier-1 vendors. From high-torque gearboxes with synthetic cooling circuits to ultra-pure 38CrMoAlA alloy steel treated via 72-hour plasma ion nitriding (HV950-1100), our supply chain delivers high durability at substantially reduced procurement lead times.
Optimal CAPEX/OPEX Ratio
Global converters benefit from a 35% to 55% reduction in total capital expenditure compared to European-built machinery without sacrificing performance. Low total energy consumption (kWh per kg throughput) alongside standard non-proprietary replacement components ensures lowest lifecycle operating expenditures.

Emerging Trends: Biopolymer Blends & AI Smart Factory Integration
Positioning your processing plant for upcoming single-use plastic restrictions, sustainable resin conversions, and Industry 4.0 data traceability.
PLA, PHA & Bio-PE Extrusion Processing
With increasing global regulations targeting non-degradable single-use plastics, modern extrusion lines must handle versatile formulations. Our systems feature multi-zone temperature profiling and custom low-shear barrier screws capable of extruding bio-based Polyethylene (Bio-PE), Polylactic Acid (PLA), Polyhydroxyalkanoates (PHA), and starch-filled compounds without premature polymer cross-linking or thermal degradation.
Multi-Layer Co-Extrusion (A/B, A/B/A)
To reduce virgin resin costs or implement functional inner barriers, our co-extrusion technology enables 2-layer and 3-layer configurations. Manufacturers can encapsulate up to 60% post-consumer recycled (PCR) PE in the core layer while preserving pristine virgin resin on the outer and inner contact surfaces for food and medical security.
Edge-AI Quality Control & Predictive Telemetry
By streaming telemetry from screw torque, melt pressure transducers, and laser gauges directly to an onboard industrial edge controller, our lines predict out-of-spec dimensions before scrap occurs. Industrial Ethernet protocols (OPC-UA, Profinet, Modbus TCP) allow plant MES systems to track batch OEE, energy consumption, and scheduled preventive maintenance schedules effortlessly.
