Explore our engineering capabilities across high-speed custom lines, medical grade tubing, and precise coating solutions.
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) founded in 2002, is dedicated to designing, manufacturing and sales of plastic extrusion equipment. Based on 18 years experience of designing and fabricating high quality machines in Taiwan, the original parent company (KINGSWEL GROUP) invested in establishing extrusion machines manufacturing base in Shanghai in 1999. Today, we are proud to offer advanced technology that serves clients across five continents.
With a quarter-century of focus on research and development, we specialize in high-precision and high-efficiency extrusion systems. Our commitment is backed by strict quality inspection, custom engineering systems, and automated software integration designed to support Industry 4.0 paradigms.
Low-Density Polyethylene (LDPE) is one of the most widely deployed thermoplastics globally. Its unique combination of flexibility, chemical resistance, low moisture absorption, and excellent impact toughness makes it indispensable for diverse applications including medical devices, automotive fluid handling, micro-drip irrigation systems, and electrical insulation. However, achieving high-speed, high-precision extrusion of LDPE requires deep technical mastery of the polymer's thermal and rheological behaviors.
To prevent structural defects like wall thickness variation, inner surface roughness, or dimensional drift, an extrusion line must control melt temperature distribution, screw shear rate, and vacuum calibration pressure with absolute precision.
The global market is witnessing an unprecedented transition towards automated, multi-layer, and high-efficiency extrusion lines. Procurement officers from North America, Europe, and Southeast Asia are shifting away from standalone machinery in favor of fully integrated extrusion systems. The demand is heavily focused on reducing operational complexity and raw material waste.
Today's procurement strategies prioritize equipment that guarantees a high return on investment (ROI) through energy efficiency, minimized scrap rates during startups, and remote diagnostic capabilities. Key requirements include gravimetric dosing systems to control material consumption, closed-loop outer diameter (OD) and wall thickness monitoring with automatic feedback to the puller and extruder, and rapid changeover systems.
Operating from Jiangsu, the manufacturing hub of China, BAOD EXTRUSION leverages the depth of our localized component supply chain to deliver high-performance systems. Our 16,000 m² facility utilizes modern CNC machining, precise assembly, and automated software integration.
Our factory integration of the "Industry 4.0" framework provides key competitive advantages:
Engineered solutions designed for high speed, stability, and precise dimensional control.
Different regions present unique environmental and regulatory conditions that necessitate customized extruder designs. BAOD EXTRUSION specializes in tailoring lines to these diverse scenarios:
For medical device manufacturers producing IV tubes, catheters, and multi-lumen tubes, our systems feature sanitary stainless-steel cooling tables, closed-loop ultra-precise vacuum sizing systems, and cleanroom compatibility (Class 10,000 / ISO 7). These measures prevent contamination and ensure strict compliance with international medical standards.
Modern automotive components demand multi-layer nylon (PA) and TPV/PVC co-extrusion for under-the-hood fluid lines, fuel vapors, and door seals. Our systems integrate precise die heads that support continuous, co-extruded layers with excellent adhesion properties, helping vehicles meet stringent emissions and noise reduction requirements.
In mining, infrastructure, and controlled demolitions, safety and consistency are paramount. Our detonating tube extrusion lines produce highly uniform micro-diameter tubes designed to perform reliably under extreme pressures and temperatures.
Agricultural deployments require long-term UV resistance and consistent flow rates. Our lines process recycled or virgin LDPE and LLDPE polymers into precise tubes with embedded emitter configurations, providing durable irrigation networks worldwide.

From April 21–24, CHINAPLAS 2026 was successfully held at the National Exhibition and Convention Center (Shanghai, Hongqiao). BAOD EXTRUSION showcased its latest R&D achievements at Booth 7.1C04, presenting "Smart Extrusion · High-Efficiency Innovation" solutions that address global sustainability demands.
In modern industrial facilities, thin plastic detonating tubes wound onto reels might seem simple, but their consistency is critical for safe mining, quarrying, and infrastructure demolition. BAOD designs custom systems to meet these high-reliability requirements.
Medical multi-lumen catheters require ultra-precise internal channels. We compare China's advanced manufacturing capabilities with European standards, showing how our local supply chain delivers global compliance and high precision at competitive price points.
As electric and lightweight vehicles demand more specialized components, BAOD maintains absolute compliance with global quality standards to ensure our automotive tubing systems perform reliably in demanding vehicle environments.
Automobile manufacturers are demanding quieter cabins and better insulation. Discover how BAOD's automated TPV and PVC sealing strip extrusion systems utilize advanced co-extrusion technology to improve automotive sealing performance.
Find answers to common technical, metallurgical, and structural questions about our polymer extrusion solutions.
For LDPE materials, we typically design screws with a Length-to-Diameter (L/D) ratio of 28:1 or 30:1, and sometimes up to 33:1 for high-speed systems. This ensures optimal melt homogeneity and effective shear control, preventing thermal degradation of the polymer.
Our extrusion lines integrate high-precision vacuum calibration tanks with multi-chamber water level and temperature control, paired with closed-loop laser diameter gauges. If the gauge detects a drift in outer diameter (OD), it sends real-time adjustments to the puller speed and extruder output to correct the deviation.
Yes. By adjusting the melt contact surfaces to high-polish stainless steel, upgrading to medical-grade vacuum tanks, and deploying cleanroom-compatible fly-knife cutter units, our systems reliably produce medical-grade tubing.
We primarily use Siemens PLC control platforms integrated with user-friendly HMI touchscreens. This provides comprehensive control over heating zones, motor speeds, vacuum pressures, and downstream synchronization, while enabling remote diagnostics and industrial IoT integrations.
Depending on complexity, custom extrusion lines are typically delivered within 60 to 90 days. This timeline includes design approvals, components sourcing, precision assembly, and pre-shipment testing at our factory.
