About Jiangsu Baodie

25 Years of Engineering Prowess in Polymer Customization

BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) established its foundational core in 2002. Since inception, our operational model has revolved around designing, engineering, and manufacturing robust plastic extrusion equipment. Expanding on a solid legacy of 18 years of design and manufacturing in Taiwan, the original parent enterprise (KINGSWEL GROUP) laid structural investments in Shanghai in 1999, which later bloomed into our state-of-the-art Jiangsu manufacturing base.

Our long-term developmental focus anchors onto high precision, ultra-efficiency, automation integration, and protective structural engineering. Our capabilities bridge the gap between high-viscosity polymer processing and micron-level accuracy, giving global manufacturers a competitive toolset to succeed.

  • Precision micrometric extrusion technologies for high-demand applications.
  • Energy-efficient drive motors with specialized L/D screw geometries.
  • Closed-loop smart process automation for lights-out manufacturing.
  • Multi-tier active machinery safety measures and fail-safe logic.

The Evolution of Polymer Extrusion & Market Dynamics

The modern industrial polymer tube extrusion sector is undergoing an unprecedented technological paradigm shift. As industries like healthcare, electric vehicles (EV), telecommunications, and aerospace demand increasingly strict mechanical tolerance parameters, conventional extrusion setups are reaching their limits. High-performance polymers, including Fluoropolymers (PTFE, FEP, PFA), Polyamides (PA11, PA12), Polyurethanes (TPU), and customized Thermoplastic Elastomers (TPE/TPV), require specialized thermodynamic and mechanical processing environments.

Global supply networks demand robust mechanical output paired with resource-conscious energy designs. System integrity is no longer just about the extruder; it spans the auxiliary line from gravimetric dosing units to advanced pullers and servo-driven rotary cutters. Jiangsu Baodie remains at the forefront of this evolution by offering fully engineered downstream integrations, enabling manufacturers to reduce scrap rates, optimize melt uniformity, and maintain continuous run-times.

Key Drivers in Today's Global Polymer Tube Processing:

  • Multilayer Co-extrusion: The necessity for fuel barriers, abrasion-resistant outer jackets, and low-friction inner layers requires multi-extruder setups feeding a single, highly specialized spiral or radial die head.
  • Dimensional Stability: For applications like medical catheters or microducts, concentricity tolerances must be controlled down to ±0.02 mm, necessitating ultra-stable vacuum sizing and non-contact laser measurement systems.
  • Smart Control Systems: Integration of PLC networks running proprietary software loops to dynamically adjust puller speeds based on real-time OD/ID feedback.

Supply Chain & Localized Support

China Factory Supply Chain Resiliency & Technical Advantages

Operating a 16,000 m² advanced manufacturing facility in China allows Jiangsu Baodie to construct premium equipment solutions at competitive capital expenditures. Our industrial ecosystem integrates high-grade raw metal supply, specialized precision CNC milling facilities, and state-of-the-art thermal treatment facilities under a single operational blanket. This tight integration ensures our engineering cycle from blueprinting to assembly occurs without quality drop-offs.

By maintaining reliable local supplier partnerships, BAOD mitigates the component lead-time shocks that currently disrupt global machinery builders. This localized synergy ensures that critical spares (such as nitrided barrels, custom screw assemblies, complex co-extrusion feedblocks, and vacuum dies) are fabricated to strict tolerances and shipped out with minimal delays.

Key Localized Application Scenarios:

  • Automotive Fluid Systems: High-tolerance multilayer lines for EV battery cooling loops, PA11/PA12 fuel lines, and high-performance TPV window weatherstrip profiles.
  • Medical Grade Micro-Tubing: Ultra-precision extrusion of medical catheters, surgical tubes, and multi-lumen pediatric airways in cleanrooms.
  • Telecom Microduct Infrastructure: Sub-surface HDPE silicone-core conduit systems for fiber-optic cabling, facilitating dense long-haul telecommunication grids.

FAQ Desk

Technical & Commercial Inquiries

Q1: What materials can Jiangsu Baodie's extrusion lines process?
Our systems process a wide range of thermoplastics, specializing in technical resins like Polyamides (PA6, PA11, PA12), Thermoplastic Vulcanizates (TPV), Thermoplastic Polyurethanes (TPU), Polyethylene variants (LDPE, HDPE), Polypropylene (PP), Fluorinated Ethylene Propylene (FEP), and Plasticized Polyvinyl Chloride (PVC) for medical usage.
Q2: How does the closed-loop feedback mechanism maintain precision tolerances?
Our systems integrate multi-axis laser measuring gauges at the exit of the cooling tank. This sensor matrix feeds dimensional values back to the PLC controller, dynamically adjusting the screw RPM and caterpillar puller speed to keep wall thicknesses and outer diameters within strict tolerances (±0.02mm).
Q3: Can BAOD design extrusion lines for cleanroom compliance?
Yes, our medical-grade tube extrusion lines feature oil-free components, enclosed vacuum systems, and stainless steel housing options to minimize particulate generation, aligning with ISO Class 7 and Class 8 cleanroom requirements.
Q4: What is the typical lead time for a custom co-extrusion line?
Standard systems require 60 to 90 days from technical approval to factory acceptance testing (FAT). Highly customized multi-layer lines or automated co-extrusion lines take 90 to 120 days, depending on auxiliary configurations.
