Explore our leading precision machinery designed to achieve optimal dimensional stability, rapid throughput, and operational safety.
Founded in 2002, BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) has positioned itself at the cutting edge of precision plastic extrusion engineering. Our industrial expertise traces its roots back to 1999 when our original parent company, KINGSWEL GROUP, brought 18 years of elite Taiwanese engineering and design capabilities to establish a world-class manufacturing facility in Shanghai. Over the course of the subsequent two decades, BAOD has specialized in the high-fidelity manufacturing and customization of advanced polymer extrusion systems.
Today, working from our 16,000-square-meter facility with a team of more than 100 experienced technicians and engineers, we serve global buyers seeking high reliability, strict mechanical tolerances, and extensive automation. Our R&D priorities consistently center around:
Achieving micron-level tolerance with smart melt distribution channels and high-stability calibration systems.
Optimized screw geometry ensuring complete plasticization and rapid output rates with reduced power consumption.
Integrating state-of-the-art PLC interfaces and remote control networks for unified, closed-loop plant operation.
The global demand for high-performance polymeric tubing has shifted drastically over the past decade. Driven by both strict environmental legislation against single-use plastics and the growing requirement for high-durability polymer conduits in telecommunication, automotive, and industrial engineering, manufacturers face a double challenge: maximizing dimensional output consistency while integrating alternative resins (such as bio-based Polyethylene and post-consumer recycled PE).
The manufacturing of Polyethylene (PE) straw tubes is no longer limited to simple consumer drinking straws. Specialized PE tubes now function as structural sub-elements, medical pathways, paint delivery channels, and micro-conduits for delicate optical fibers. Achieving reliable wall thickness parity, perfect circularity, and high-frequency clean cuts at speed is a complex physical challenge involving melt temperature controls, high-speed pull-off calibration, and accurate pressure differentials.
Unlike polymers with low shear-sensitivity, PE exhibits pronounced shear-thinning characteristics under high-pressure processing conditions. This means the screw profile of the extrusion line must be engineered specifically to balance melt temperatures and avoid material degradation. BAOD Extrusion systems feature barriers and mixing elements on the screw to ensure homogenous temperature profiles across the melt before it enters the extrusion die.
To produce a consistent tube from Polyethylene, a series of precisely calibrated operations must occur in a continuous, synchronized sequence. The standard BAOD PE Straw Tube Extrusion Line incorporates several advanced stages:
Industrial clients across different global territories deploy the PE Straw and Tube Extrusion Line to meet highly distinct local market demands:
Micro-Ducts and Silicone Core Conduits: Used heavily in Europe and North America. Extrusion lines produce multi-layer HDPE conduits with an inner low-friction silicone layer for blowing fiber-optic cables over long distances.
Fluid & Gas Delivery Lines: Precision micro-tubing manufactured under ISO Class 8 cleanrooms. The extrusion line must support strict dimensional stability controls down to ±0.02mm tolerances.
Sustainable Eco-Straws: Adaptable systems that run both LDPE/HDPE and PLA/PHA biodegradable compounds. Features custom cutter geometries to support angle cuts for aseptic juice carton packaging.
The future of polymer extrusion lies in full-process digital twins and closed-loop feedback systems. By integrating high-frequency ultrasonic wall-thickness monitors immediately downstream of the cooling tank, BAOD Extrusion systems can dynamically adjust the position of the calibration tooling or change the screw speed in real time.
Additionally, the rise of industrial Internet of Things (IoT) protocols, such as OPC UA, allows BAOD machines to transmit telemetry data—such as melt pressure, motor torque, heater power draw, and cooling water flow rates—directly to enterprise resource planning (ERP) software. This level of oversight ensures predictive maintenance schedules can be executed before physical failure occurs, limiting unexpected downtime to zero.
Based in Jiangsu, BAOD Extrusion leverages the robust industrial clusters of the Yangtze River Delta. This location grants direct access to specialized metallurgical treatment centers, high-grade motor manufacturers, and advanced electrical component providers. By combining Taiwanese precision design heritage with the sheer scale and efficiency of China’s supply chain, BAOD delivers high-durability machines at a highly competitive total cost of ownership (TCO).
Our vertical integration ensures that critical mechanical parts—such as screws, barrels, and die heads—are machined in-house on high-precision CNC tool centers. This reduces reliance on external vendors, enables rapid adaptation to custom client requests, and guarantees long-term spare parts availability.
To operate safely in environments such as Europe, the Americas, and Southeast Asia, BAOD Extrusion systems comply with international standards including CE directives and ISO 9001:2015 quality frameworks. Electrical panels are built using internationally recognized components (such as Siemens, Schneider, and Omron) to make sure local maintenance teams can source parts easily.
Our service engineers assist during site preparation, mechanical installation, electrical connection, and trial runs. We also provide online diagnostics to troubleshoot sensor readings and PLC configurations, helping to keep operations running smoothly without the need for onsite visits.
