Explore our premium grade extrusion lines engineered for high precision, mechanical reliability, and structural integrity across diverse materials and composite specifications.
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) is dedicated to designing, manufacturing, and supporting advanced plastic extrusion equipment globally.
Leveraging over 25 years of engineering and design expertise in high-precision plastic machinery originating from the Kingswel Group investment in Shanghai (1999) and Taiwan-based technological heritage, BAOD EXTRUSION specializes in fabricating high-end extrusion lines. With a focus on process automation, mechanical reliability, and structural innovation, we deliver tailor-made configurations to help downstream processors optimize production costs and product yields.
Providing custom multi-layer and single-wall corrugated tubing systems designed for rigorous operational environments in modern automotive, chemical, and solar engineering.
Utilizes multi-manifold die heads and co-extrusion feedblocks designed with CFD flow analysis. This secures precise thickness distribution across individual layers, preventing thin spots that cause barrier leaks or structural failure.
Continuous corrugating blocks featuring forced water-cooling or air-vacuum mechanisms. This enables fast forming of single-wall and multi-layer corrugated profiles without deformation at high extrusion rates.
Siemens/Beckhoff PLC architecture coordinating the extruder output, melt pump pressure, corrugator forming speed, and puller tension dynamically. This ensures batch-to-batch repeatability and minimal scrap rates.
A comprehensive breakdown of BAOD's engineering capabilities and specialized machinery components for multi-layer and high-precision extrusion applications.
Manufacturing multilayer corrugated tubes (typically 3, 5, or even 7 layers) requires precise synchronization of several distinct machinery components. BAOD EXTRUSION designs and fabricates every component in-house to ensure high operational integration.

How BAOD EXTRUSION bridges the gap between cost-efficient Chinese manufacturing and stringent global safety standards.
Industrial components manufactured for international markets must comply with various regional safety and performance directives. At BAOD EXTRUSION, all export machines are designed to meet European CE directives, UL electrical safety standards, and global ISO guidelines.
This compliance strategy allows machinery buyers in Europe, North America, and South America to integrate our extrusion systems seamlessly into their plants. By choosing our machines, you get European-level engineering precision along with the logistical agility and cost advantages of our 16,000 m² factory in China.
Driving the next generation of plastic extrusion through automated quality controls and smart factory integrations.
Integrating downstream laser gauging and ultrasonic scanners with the central PLC allows the system to auto-adjust screw speeds and melt pump pressure in real-time, keeping wall thicknesses consistent.
Optimizing screw designs to process PCR (Post-Consumer Recycled) polymers and bio-based polyamides (like PA11) without sacrificing mechanical performance or barrier reliability.
By using direct-drive motors, high-efficiency induction heating bands, and closed-loop cooling circuits, we reduce energy consumption per kilogram of extruded product by up to 25%.

Expert answers to common engineering questions about multi-layer co-extrusion systems.
EVOH (Ethylene Vinyl Alcohol copolymer) acts as a highly effective gas and hydrocarbon barrier. In automotive fuel lines, it prevents volatile hydrocarbons from permeating through the plastic walls, helping the vehicle meet strict emissions standards. In EV cooling lines, it prevents oxygen permeation, helping maintain coolant fluid balance and protecting electronics.
We use custom co-extrusion flow distributors and spiral mandrel dies designed using computational fluid dynamics (CFD). This ensures that polymers with different melt indexes distribute evenly around the tooling. We also integrate gravimetric dosing systems and online ultrasonic thickness gauges to monitor and control layer thickness in real time.
Depending on the polymer (PA, PE, PP, or PVC) and the pipe diameter, our lines can operate at speeds up to 30 meters per minute. This is achieved by utilizing an optimized corrugator design with continuous vacuum forming blocks and high-capacity cooling systems.
All our machinery is built to meet CE and UL safety specifications. We supply complete bilingual document packages and provide remote diagnostics. For installations, we send senior engineers to set up the equipment, optimize the extrusion dies, and train local staff at your facility.
Yes, our SJ series single-screw extruders are available with customized bimetallic barrels and wear-resistant screw geometries. These are designed specifically to handle abrasive materials, highly filled flame-retardant polymers, or glass-fiber reinforced compounds without accelerated wear.
