Explore our premium machinery components and configurations, engineered for continuous operation and strict dimensional tolerances.
Established in 2002, BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) has developed a strong global reputation for designing, manufacturing, and supporting advanced plastic extrusion systems. Drawing on 18 years of prior design and manufacturing experience in Taiwan through our parent firm, KINGSWEL GROUP, our manufacturing capabilities were formally established in Shanghai in 1999.
Over decades of targeted design and machinery builds, our engineering department has maintained a long-term research focus on high-efficiency output, absolute automated process controls, precision calibration, and safety engineering. This focus delivers repeatable, high-output production lines for automotive, medical, and specialized industrial applications globally.
Certified workflows and in-house CNC machining centers secure repeatable mechanical builds.
A global outlook on engineering requirements, smart controls, and sustainable plastic materials.
Modern manufacturing sectors demand increasingly strict dimensional tolerances. Industries such as automotive manufacturing and medical therapeutics no longer accept the variance profiles common in traditional extrusion runs. The global plastic extrusion machinery market is transitioning from simple volume-based throughput to precision-centric, intelligent manufacturing lines.
This change is driven by the growing use of engineering polymers (such as Fluoroplastics, PU, PA, and UHMWPE) that require precise thermal controls. The processing window for these polymers is extremely narrow, making mechanical configuration critical. China's manufacturing sector has evolved from copying designs to developing its own technology. Manufacturers now supply systems with European-standard precision at competitive price points.
The integration of the Industrial Internet of Things (IIoT) is changing the extrusion plant floor. Modern lines use ultrasonic wall-thickness monitors, gravimetric material feed controls, and automatic vacuum adjustment systems.
By continuously measuring the tube profile downstream, the puller speed and vacuum pressure can be adjusted dynamically in real time. This closed-loop configuration minimizes human intervention, reduces scrap rates during start-up, and guarantees consistency across miles of continuous extrusion.
Extrusion lines must perform reliably under varied environmental and local conditions. In high-humidity climates, advanced raw-material drying and dehumidifying systems are integrated directly into the feeding system. For high-altitude regions, vacuum pump motors are resized to compensate for lower ambient atmospheric pressures, protecting the integrity of the tube sizing process.
In medical cleanrooms (ISO Class 7/8), extrusion systems are built with stainless steel framing, zero-emission lubricant-free vacuum lines, and integrated exhaust management systems to prevent raw material outgassing from contaminating the workspace.
Industrial scale-up requires more than standalone extruders. BAOD provides comprehensive turnkey solutions that manage the entire process line. This includes raw material pneumatic feeding, centralized PLC controls, extrusion, calibration, coiling, and packing.
Coordinating the speed of the single-screw extruder with the melt pump, puller speed, and automatic coiler controls avoids tension-induced deformation. This integration ensures the extrusion line runs reliably at maximum capacity.
How specialized engineering addresses the physical challenges of processing complex polymers.
Processing fluoroplastics requires specialized metallurgy. FEP and PVDF release highly corrosive gases when heated to molten state. BAOD utilizes custom nickel-alloy screws and barrels (e.g., Hastelloy or Xaloy) alongside precise multi-zone heating bands to prevent corrosion and thermal degradation.
TPV and TPU display highly elastic behaviors but are sensitive to shear forces. Custom screw profiles are engineered to avoid material degradation while ensuring uniform color dispersion. Specialized cooling channels within the vacuum sizing tank prevent post-extrusion shrinkage.
Industrial fuel and brake lines require multi-layer hoses (e.g., PA/Adhesive/EVOH/Adhesive/PA) to prevent fuel vapor leakage. BAOD's multi-layer crosshead dies control layer distribution precisely down to the micron level, ensuring consistent adhesion and layer thickness.

Essential guidance and engineering support for selecting, installing, and running precision extrusion lines.
We integrate high-frequency ultrasonic thickness monitoring systems with closed-loop Siemens PLC processors. If the dimensions deviate, the line automatically adjusts the vacuum sizing tank pressure and puller speed to bring the profile back within tolerance.
For corrosive fluoropolymers, we use dedicated nickel-based alloys (such as Hastelloy or Xaloy) for the barrel and screw. This setup resists chemical corrosion at processing temperatures up to 400°C, ensuring reliable operation.
Standard single-layer extrusion lines generally take 60 to 90 days to manufacture and test. Custom multi-layer lines or automated turnkey setups require 90 to 120 days, which includes factory acceptance testing (FAT) before shipment.
Yes, all BAOD extrusion lines are engineered and manufactured in compliance with international CE directives. Electrical panels use UL or CE-certified components (such as Siemens, Schneider, and Omron) to ensure compliance with global industrial safety codes.
