Precision OEM & Custom Screw Extrusion Machinery
Macro-Level Manufacturing Architecture & Precision Engineering
The global plastic screw extrusion process is undergoing a paradigm shift driven by smart manufacturing, material science advancements, and high-tolerance design standards. Originally developed to shape polymer compounds continuously, contemporary extrusion technology must handle advanced thermoplastic elastomers (TPV, TPU), engineering fluoropolymers, and multi-layer composites (PA/PE/PP/PVC).
For global procurement managers, identifying top-tier China screw extrusion process factories is no longer just about cost reduction. It is about locating suppliers who integrate Taiwanese engineering precision with Chinese mainland manufacturing speed and scale, ensuring compliance with strict European and American safety directives (CE, ISO, RoHS).
Who We Are
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.), founded in 2002, is dedicated to designing, manufacturing, and sales of high-performance plastic extrusion equipment. Based on 18 years of experience designing and fabricating high-quality machinery in Taiwan, the original parent company (KINGSWEL GROUP) invested in establishing our primary extrusion machines manufacturing base in Shanghai in 1999.
With a comprehensive 25 years of research, design, and manufacturing experience in plastic extrusion, our R&D focus remains dedicated to:

Melt Homogeneity, Die Design, and Calibration Technology
The core challenge in precision screw extrusion lies in maintaining structural and dimensional integrity under high throughput pressures. At the heart of the system is the SJ Series Single Screw Extruder. Understanding polymer rheology under shear stress allows BAOD designers to optimize screw geometries (L/D ratios ranging from 25:1 to 33:1) for specific applications:
Real-time calculation of material density ensures exact polymer weight per meter, minimizing material loss and keeping inner and outer diameter tolerances within ±0.05 mm.
By using auto-vacuum control sizing tanks, the extrudate undergoes immediate solidification. This is critical for medical tubes and micro-ducts requiring zero structural distortion.
Synchronized pulling systems (TKB and QYP Series Belt Pullers) prevent stretching during pull-off, while fly-knife cutters guarantee clean, perpendicular cuts.

Solving Complex Global Supply Chain & Operational Pain Points
Purchasing screw extrusion equipment from overseas involves significant technical and financial decisions. Industrial buyers frequently report challenges regarding dimensional precision, mechanical wear, energy waste, and lack of technical support.
BAOD addresses these pain points by offering modular, turnkey extrusion systems. Whether you are sourcing components for automotive sealing systems, detonating tubes for mining, or high-speed telecommunications micro-ducts, BAOD's localized design ensures rapid integration into existing factory lines.
Our screw designs are customized with specialized coatings (like bimetallic liners) that prevent degradation when processing aggressive raw materials or corrosive fluoropolymers.
The Path Towards Autonomous Closed-Loop Extrusion Systems
The future of the screw extrusion process relies on intelligence and decarbonization. Over the next decade, BAOD Extrusion is transitioning its equipment portfolio towards three primary developmental pillars:
Integrating predictive algorithms to control barrel temperatures based on feed rates and melt pressure changes, cutting energy consumption by up to 20%.
Automated adjustment of calibration sleeves and vacuum levels in real-time, eliminating off-spec start-up scrap during tooling changes.
Custom-engineered screws designed to process post-consumer recycled (PCR) plastics without suffering raw material output fluctuations.
