Featured precise extruders, downstream systems, calibration units, and pullers designed for high stability.
Founded in 2002, BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) has positioned itself at the global forefront of high-precision plastic extrusion technology. Backed by 18 years of prior design and manufacturing experience in Taiwan through the original parent company KINGSWEL GROUP, which established its primary extrusion engineering base in Shanghai in 1999, our organization represents a rich heritage of top-tier manufacturing excellence.
Over the past 25 years, we have maintained a strict focus on the research, development, and engineering of customized polymer extrusion lines. Our dedicated team is continuously pushing the boundaries of:
Deciphering the physics, material characteristics, and mechanical configurations of Thermoplastic Vulcanizate extrusion.
TPV (Thermoplastic Vulcanizate) exhibits a complex rheological profile requiring low-shear, highly homogeneous melting. Our SJ-series single-screw extruders deploy customized L/D ratios of 28:1 to 33:1, barrier screws with mixing elements, and multi-zone heating barrels to ensure zero degradation of the crosslinked EPDM phase within the PP matrix.
To secure tight dimensional tolerances (±0.05 mm) in automotive fluid hoses, we engineer dynamic auto-vacuum sizing tanks. Featuring closed-loop vacuum regulation, micro-adjustable 3D calibrator tables, and high-volume spray cooling, our system prevents cross-sectional ovality and tube collapse during high-speed production cycles.
The synchronization of the puller and cutting units dictates the physical consistency of finished automotive tubes. BAOD integrates multi-belt traction pullers managed by servo drives alongside intelligent rotary fly cutters. This maintains linear speeds without tube slippage, ensuring clean, perpendicular cuts for post-processing assembly.
"The shift towards Thermoplastic Elastomers (TPEs) like TPV in the automotive space is heavily driven by vehicle light-weighting goals and strict ESG mandates. Modern OEMs require extrusion equipment capable of handling highly sensitive thermal windows while running uninterrupted 24/7 cycles." - Kingwel Group Engineering Whitepaper
Addressing the paradigm shift in smart manufacturing, digitalization, and material science adaptation.
To eliminate manual inspection and downstream waste, future BAOD TPV lines incorporate real-time multi-axis laser gauging systems. Located immediately after the sizing tank, these sensors monitor outer diameter (OD), inner diameter (ID), and wall thickness. Feedback signals are instantly processed by the central PLC, dynamically adjusting screw RPM and puller speeds to maintain structural integrity.
Through our proprietary Smart Extrusion Architecture, temperature sensors, pressure transducers, and motor vibration monitors stream diagnostic data directly to local SCADA networks or cloud servers. Using machine learning models, our systems predict bearing failures or heater band outages days before they manifest, guaranteeing unprecedented levels of OEE (Overall Equipment Effectiveness) to global tier-1 automotive suppliers.
As cooling requirements for EV (Electric Vehicle) battery packs become more complex, multi-layered tubes (e.g., TPV + PA + Adhesives) are increasingly necessary. BAOD's technology roadmap features proprietary multi-layer co-extrusion crossheads, optimized with computational fluid dynamics (CFD) software to ensure balanced polymer flow distribution and flawless layer adhesion without thickness variations.
How BAOD Extrusion solves critical global manufacturing requirements for the automotive supply chain.
Electric vehicles demand vast arrays of thermal management coolant tubes. These hoses must resist glycol degradation and high pressures while maintaining flexibility. BAOD’s TPV tube extrusion lines allow manufacturers to form tight-tolerance, lightweight EV coolant lines that easily replace heavy metal pipe assemblies or expensive silicone rubber alternatives.
High temperatures and petrochemical exposure require under-the-hood tubes to meet strict criteria. Our lines produce TPV vacuum lines, windshield washer hoses, and cabin ventilation tubes that withstand extreme environmental stress, showing zero deterioration under continuous cyclic heat up to 135°C.
All extrusion machinery is engineered to integrate seamlessly into plants operating under ISO 9001 and IATF 16949 quality frameworks. Data logging capabilities allow complete traceability of melt pressures, extrusion speeds, and temperature logs for every production batch, making OEM audits trouble-free.
Combining competitive operational costs with rigorous engineering control and direct localized support.
Operating a 16,000 square meter state-of-the-art facility in Jiangsu, China, BAOD Extrusion combines the manufacturing efficiency of China’s mature industrial clusters with precision Taiwanese engineering legacy. Our proximity to premium steel foundries, high-end motor suppliers, and digital control system developers enables us to shorten equipment manufacturing times while providing superior mechanical resilience.
For international buyers concerned with geopolitical and supply chain risks, BAOD addresses compliance directly. We use top-tier global components (such as Siemens PLC modules, Schneider electricals, ABB drives, and Omron temperature controllers) as standard, ensuring that replacements and service parts can be procured locally in North America, Europe, or Southeast Asia. Additionally, our pre-shipment FAT (Factory Acceptance Test) protocol includes digital live-streaming of testing trials, letting client engineers verify machine tolerances remotely before shipping.
