Yaoan Brand 65/65 Single Screw TPU Braided Hose Extrusion Production Line

—Professional Solution for High-Strength, High-Precision, and High-Stability Reinforced Hose Manufacturing

I. Core Line Configuration

This production line is designed for manufacturing high-end TPU (Thermoplastic Polyurethane) braided reinforced hose. It features a classic "65mm inner layer extruder + 65mm outer layer extruder" dual-extruder configuration and a high-precision braiding reinforcement system, enabling integrated, automated production from raw material to finished product.

1. Precision Extrusion System

• Dual 65mm Single Screw Extruders:

  • Main Extruder: For extruding the smooth, dimensionally accurate TPU inner tube.

  • Co-extruder: For coating the TPU outer layer, perfectly impregnating and encapsulating the braid.

  • Key Features:

    • High-Efficiency Screw: Optimized for TPU material characteristics, ensuring uniform plasticization, stable output, and resistance to hydrolytic degradation.

    • Temperature Control System: Utilizes imported PID modules and cast aluminum heaters paired with high-capacity cooling fans, achieving precise control within ±1°C across barrel, flange, and die zones.

    • Gearbox: Heavy-duty design for high load capacity, smooth operation, and low noise.

2. High-Dynamics Braiding Reinforcement System (Core of "Braiding")

• High-Speed Precision Braider: Standard 16 or 24 carriers (more optional) for producing hoses with different pressure ratings.

  • Magnetic Tension Control System: Independent, adjustable tension per carrier ensures uniform yarn tension and consistent reinforcement structure, eliminating "snaking" or pressure instability.

  • Optimized Yarn Path: Ceramic guides minimize wear and protect yarns (polyester, aramid, etc.) from damage.

  • Synchronized Drive: Linked to the main PLC, allowing stepless adjustment of braid pitch and perfect synchronization with extrusion speed.

3. Core Forming Module – Composite Co-extrusion Die Head

• Multi-Layer Flow Composite Die: Features Yaoan's patented basket-style design.

  • Inner Layer Flow: Guarantees uniform wall thickness of the inner TPU tube.

  • Braid Positioning Inlet: Precisely guides the braid between the inner and outer layers.

  • Outer Layer Flow: Achieves complete 360° encapsulation and impregnation of the braid by TPU melt, ensuring strong interlayer adhesion and no exposed yarns.

  • Construction: High-quality alloy steel, chrome-plated and polished for smooth, dead-zone-free flow paths that prevent TPU stagnation and degradation.

4. Efficient Cooling & Sizing System

• Stepped Cooling Tank: Customizable length (typically 6-12m) with multi-zone temperature control.

  • Initial zones use warm water for gradual cooling to reduce internal stress; middle/final zones use chilled water for rapid sizing.

  • Equipped with water level/temperature regulators and multi-level guide rollers to ensure straightness, perfect roundness, and no deformation.

5. Precision Haul-off & Take-up System

• Four-Belt Haul-off Unit: Two upper and two lower belts provide evenly adjustable gripping force. Speed is fully closed-loop synchronized with extrusion and braiding, preventing slippage and ensuring consistent hose OD and wall thickness.

• Dual-Station Automatic Take-up / Cut-to-Length Unit:

  • Take-up Mode: Torque motor control ensures constant winding tension and neat coils.

  • Cutting Mode: Integrated with high-precision length counter and flying saw/swing cutter for automatic cut-to-length, dumping, and optional inkjet printing.

6. Intelligent Central Control System

• Industrial PLC + Color Touchscreen: Centralized control for the entire line.

  • One-Touch Start/Stop & Synchronized Speed Adjustment: Simple operation.

  • Full-Parameter Monitoring: Real-time display and logging of all key parameters (temperatures, speeds, tensions, length, etc.).

  • Fault Self-Diagnosis & Alarm: Automatic alerts and shutdown protection for overloads, overtemperature, yarn breakage, etc.

  • Recipe Storage: Stores multiple product parameter sets for quick changeovers

II. Key Advantages of the Production Line

1. Exceptional Product Performance

• High Strength & Pressure Resistance: Precise tension control and braid angle maximize reinforcement efficiency, yielding hoses with high burst pressure and long pulse life.

• Superior Interlayer Adhesion: Patented die design combined with optimized process ensures molecular-level bonding between TPU and yarn, preventing delamination and offering excellent flex fatigue resistance.

  • High Dimensional Accuracy: Stable extrusion, synchronized haul-off, and uniform cooling guarantee hose ID, OD, roundness, and wall thickness tolerances far exceed industry standards.

2. Outstanding Production Efficiency & Stability

• High-Output Dual 65 Configuration: Ideal for mainstream TPU braided hose sizes from Φ6mm to Φ25mm (and larger), offering high output and line speed.

• High Synchronization Precision: Full servo or inverter-based sync control ensures perfect speed matching between extrusion, braiding, and haul-off, significantly reducing scrap rates.

• Strong Continuous Operation Capability: Robust construction of key components ensures reliable, long-duration uninterrupted production, minimizing downtime and maintenance costs.

3. High Level of Intelligence & Ease of Use

• "User-Friendly" Operation: Intuitive HMI with visual process flow and one-touch setting of key parameters reduces dependency on highly experienced operators.

• Process Traceability: Automatic production data logging facilitates quality tracing and process optimization.

• Quick Changeover: Modular design allows for easy changes in braider carriers, dies, and take-up methods. Combined with recipe storage, this drastically reduces setup time.

4. Excellent Cost Control & Energy Efficiency

• Low Reject Rate: High stability and precise control minimize raw material waste from the source.

• Energy-Saving Design: Extruders use high-efficiency motors and heaters with good insulation; optimized power system matching results in lower overall energy consumption compared to similar lines.

• Low Maintenance Cost: Easy-clean design and readily available standard parts contribute to long service life and low upkeep.

5. Strong Brand Service & Support

• Yaoan Dedicated Service: Provides a "turnkey" service package covering plant layout planning, installation & commissioning, process training, and lifelong technical support.

• Adequate Spare Parts Supply: Critical spare parts are kept in stock year-round to ensure uninterrupted production for customers.
