Engineered for extreme dimensional accuracy, high structural integration, and stable continuous performance.
Founded in 2002, BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) is a state-of-the-art enterprise dedicated to the design, manufacturing, and global sales of advanced plastic extrusion equipment. Our engineering DNA traces back to our parent group, KINGSWEL GROUP, which established a world-class manufacturing center in Shanghai in 1999, leveraging decades of top-tier extrusion technology design from Taiwan.
For more than 25 years, our elite engineering teams have focused on the research, mechanical validation, and system integration of:
Understanding layer adhesion, thermal parameters, and barrier optimization for mission-critical industrial applications.
Our custom multi-layer die heads feature optimized flow channels calculated via 3D melt flow simulation (CFD). This ensures uniform layer distribution, eradicates weld lines, and prevents delamination between highly dissimilar materials like Polyamide (PA) and Fluoropolymers (PVDF).
By continuously monitoring the weight-per-meter output of each individual extruder, our systems maintain layer consistency down to ±0.01mm. The closed-loop control system automatically adjusts screw speeds relative to line haul-off velocity to minimize raw material waste.
Downstream integration of ultrasonic scanning systems continuously monitors total wall thickness, layer concentricity, and outer diameter dimensions. Real-time feedback loops correct centering offsets instantly without stopping the production line.
In high-pressure fluid transfer systems, single-layer extrusions often fail to meet compound specifications. Modern automotive standards require low hydrocarbon permeation (Euro 6d/EPA regulations), high mechanical stiffness, and chemical resistance to aggressive fuels and battery coolants. A customized multi-layer line resolves this by co-extruding up to 3, 5, or even 7 layers of distinct polymers (such as PA11/PA12, EVOH, PVDF, and tie layers/adhesives) into a single, cohesive tube wall.
A critical engineering challenge in co-extrusion is matching the viscoelastic behavior of different melt streams inside the feedblock and die. Dissimilar viscosity curves can lead to interfacial instability, causing wavy interfaces and compromised mechanical strength. BAOD solve this by applying custom screw design profiles (L/D ratios, mixing elements) customized for specific polymer characteristics and utilizing thermal isolation within the multi-flow die head to prevent thermal degradation of temperature-sensitive barrier materials like EVOH.
How leading OEMs and Tier-1 automotive and industrial system integrators source custom extrusion lines.
For industrial buyers, purchasing an extrusion line is not merely buying machinery; it is investing in a turn-key production system designed to meet strict regulatory audits. BAOD provides custom configurations for various global application matrices:
Procurement teams must carefully verify localized compliance requirements (UL, OSHA, CE, FDA) and evaluate the total cost of ownership (TCO). High-efficiency extrusion technologies from BAOD reduce energy consumption by up to 20% compared to traditional models, drastically lowering utility bills during 24/7 continuous runs.
