Explore our primary selection of high-precision small scale extrusion lines, vacuum calibration systems, and downstream winding accessories engineered to meet strict CE compliance standards.
Founded in 2002, BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) has positioned itself as an industry pioneer dedicated to the design, manufacturing, and global distribution of advanced plastic extrusion machinery. Leveraging 25 years of technical expertise inherited from Taiwan's precision engineering sectors—sparked by the initial investment of the parent company (KINGSWEL GROUP) in Shanghai in 1999—we maintain state-of-the-art production infrastructures.
Our commitment lies in delivering high-efficiency extrusion technologies that reduce overall energy consumption while maximizing dimensional stability in micro-tubing. From medical-grade cleanroom setups to heavy-duty industrial coatings, BAOD systems are optimized for absolute process reliability and automated manufacturing workflows.
For more than two decades, we have bridged the gap between cost-efficiency and technical mastery. Our facility spans multiple advanced workshops equipped with digital machining tools, assuring that every single assembly component undergoes rigorous quality control.
Small scale plastic extruders (typically defined by screw diameters ranging from 12mm to 45mm) have evolved from simple laboratory tools into core manufacturing assets. The global push for miniaturization, medical tubing, and custom color masterbatch development has generated huge demand for agile, high-precision extrusion systems.
Traditional large-volume extruders struggle with the thermal degradation of premium engineering polymers (such as PEEK, fluoropolymers, and bio-absorbables) during long residence times. Small scale systems mitigate this by maintaining tight control over shear rates and material throughput, enabling high-value, small-batch manufacturing.
Chinese manufacturers, spearheaded by specialized hubs like Jiangsu, offer a compelling balance of cost-efficiency and engineering quality. At BAOD Extrusion, we achieve this by locating our 16,000 square meter factory in close proximity to major domestic tooling, steel casting, and automation component supply chains.
Our streamlined workflow combines proprietary Taiwanese structural design standards with local production efficiency. This enables us to provide custom-tailored barrel zones, premium wear-resistant coatings, and integrated vacuum sizing tables at significantly reduced lead times compared to North American or European counterparts.
The applicability of small scale extrusion technology spans diverse industries. In North America and Europe, our extruders are commonly utilized in clinical-grade cleanrooms for medical catheter production, where diameter tolerances are measured in microns.
In highly industrial manufacturing regions, these extruders are configured for automotive applications, producing PA (Nylon) fuel lines and TPV multi-layer weather strips. The flexibility to quickly swap modular dies makes these systems ideal for university laboratories conducting material research.
The core performance of any custom small-scale extruder depends on its screw geometry. Standard single-screw units require customized Length-to-Diameter (L/D) ratios (usually ranging from 25:1 to 30:1) to guarantee complete melting and uniform blending without causing degradation in heat-sensitive resins like PVC or TPU.
By utilizing advanced simulation software, our engineering team optimizes compression ratios and shear zones. This process customizes the hardware for specialized applications such as fluoropolymers (FEP/PTFE) used in high-frequency signal cables, or biodegradable PLA composites used in medical implants.
Our specialized product groups are built for extreme durability, combining high-speed automated output with user-friendly touchscreen HMI control.
Key parameters and technical requirements that procurement officers and design engineers must consider when sourcing small-scale industrial extrusion lines.
In micro-scale applications, particularly in medical lumen tubing and automotive fuel tubes, maintaining a consistent wall thickness is critical. Modern specifications require online laser measurement sensors that feed back to the puller unit, stabilizing the Outer Diameter (OD) and Inner Diameter (ID) in real time.
High-viscosity engineering plastics require heavy-duty gearboxes with high torque ratios. We source and implement high-efficiency AC motors driven by precision frequency inverters, ensuring steady torque output even at low-speed operations to prevent melt flow surges.
An extrusion line is only as fast as its slowest component. Sourcing a high-efficiency line requires matching the extruder with matching components, such as the FQ Series Rotary Fly Knife Cutter and high-speed automatic tension control winders, to avoid oval deformation.

Expert answers to technical questions about small-scale extruder performance, material choices, and customization options.
A small scale extruder generally utilizes screw diameters from 12mm up to 45mm. While laboratory scale systems are primarily designed for testing small formulation samples, our small-scale industrial extruders are constructed for continuous, 24/7 production runs. They feature rugged motors, high torque output, and complete downstream integration for manufacturing high-precision medical tubes, micro-tubing, and custom profiles.
We achieve this precision by linking our Siemens PLC control system with high-speed multi-axis laser measuring systems. If any deviation is detected in the tube diameter, the closed-loop system instantly makes microscopic adjustments to either the melt pump pressure, the puller speed, or the vacuum calibration level.
Yes. We custom design our extruder barrels and screws using highly heat-resistant alloys, along with high-output ceramic band heaters that can consistently operate at temperatures up to 450°C. For corrosive polymers like fluoropolymers, we apply specialty treatments to prevent early wear on the screw flighting.
Vacuum calibration is vital for hollow profiles and tubes to prevent wall collapse. By drawing a vacuum inside the sizing chamber, the molten polymer is pulled outward against a precision sizing sleeve. This process ensures consistent tube dimensions and wall thickness, which cannot be achieved using standard cooling baths alone.
All equipment is securely packed in export-grade wooden crates with protective barriers against rust and moisture. We offer comprehensive support options, including step-by-step remote video assistance, FAT (Factory Acceptance Testing) run-throughs, and onsite engineering visits for system installation and operator training.
