BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.), founded in 2002, is a premier enterprise dedicated to designing, manufacturing, and sales of high-performance plastic extrusion equipment. Based on 18 years of experience in designing and fabricating high-quality machines in Taiwan, our original parent company (KINGSWEL GROUP) invested in establishing a state-of-the-art extrusion machinery manufacturing base in Shanghai in 1999.
Our company focuses on continuous technological improvements, leveraging engineering expertise from Taiwan combined with mainland China's robust industrial supply chain. Over the years, BAOD EXTRUSION has emerged as an industry leader in customized engineering, delivering highly robust, automated, and safe extrusion lines for complex coatings, pipes, and profiling.
With decades of experience spanning diverse international regulatory environments, we have developed manufacturing workflows that meet rigorous ISO 9001 certifications. Our dedication to safety and stability ensures that every extrusion coating line operating under the BAOD brand delivers consistent performance with minimum downtime.
Analysis of Polymer Coating Technologies, Structural Pipe Coating Lines, and Global Industrial Trends.
Extrusion coating and sheathing lines represent one of the most critical technology verticals in modern polymer processing. These complex, integrated lines facilitate the continuous application of plasticized polymers onto linear substrates—ranging from steel wires, automotive metal brake lines, and multi-layer PA hoses, to compensation chains and flexible corrugated pipes.
Historically driven by simple corrosion prevention, the global commercial sector now demands multifunctional barriers. Industries like automotive manufacturing, construction, energy distribution, and medical technology require extrusion lines capable of co-extruding specialized engineering plastics (such as Polyamide 11/12, Thermoplastic Vulcanizates (TPV), Polyurethane (PU), and Fluoropolymers) onto moving substrates with sub-micron precision.
As a leading manufacturer in China, BAOD Extrusion addresses this global demand by implementing Taiwan-engineered high-precision mechanics with advanced sensor matrices, ensuring process stability at high linear speeds.
A standard extrusion coating line requires seamless synchronization across multiple dynamic subsystems:
Modern automotive architectures require multi-layer PA (Nylon) smooth and corrugated hoses. These structures must withstand fluctuating heat zones, high pressures, and chemical fuel degradation. By using co-extrusion technology, BAOD lines apply external protective barriers (like TPV or PVC) onto internal PA cores, meeting demanding global automotive safety standards.
In infrastructure projects, elevator compensation chains and structural steel wire strands are subject to mechanical abrasion and environmental oxidation. Extrusion coating lines apply heavy-duty polyethylene (HDPE) or PVC sheaths onto these metal surfaces. The process requires precise temperature controls at the metal-polymer interface to ensure proper adhesion.
Medical tubes, including multi-lumen catheters, demand strict cleanroom compliance and highly precise manufacturing tolerances. BAOD’s high-speed PVC medical tube extrusion lines feature ultra-precise laser diameter measurement systems that adjust screw output and line speeds in real-time, preventing micro-deviations.
Looking towards 2026 and beyond, BAOD Extrusion is focusing on three main development paths:
