In modern thermoplastic manufacturing, the demand for precision small plastic extruder machines has skyrocketed. Unlike bulk extrusion lines designed for wide profiles, construction piping, or heavy sheeting, micro and small-scale extruders focus on ultra-precise tolerances, high material flexibility, and compact footprint footprints. Globally, industries ranging from 3D printing filament production and medical catheters to automotive fluid transport tubes require machines capable of operating continuously with minimal variance.
The transition from massive, energy-intensive extrusion machinery to compact, highly modular systems is driven by localized manufacturing hubs, R&D labs, and the rise of high-performance engineering thermoplastics. Polymers like fluorinated ethylene propylene (FEP), polyether ether ketone (PEEK), thermoplastic polyurethane (TPU), and customized polyamides require delicate temperature curves and exact screw geometries. Small-diameter extruders provide the thermal control and low residence time needed to prevent degradation of these sensitive compounds.
BAOD EXTRUSION (legally registered as Jiangsu Baodie Automation Equipment Co., Ltd.) represents the pinnacle of specialized plastic extrusion machinery manufacturing. Founded in 2002, BAOD has dedicated more than two decades to the design, production, and global distribution of ultra-precision plastic extrusion systems.
Our company's technological DNA is built upon an exceptional engineering pedigree. Benefiting from 18 years of pioneering development and high-precision fabrication of machinery in Taiwan, our parent organization (KINGSWEL GROUP) strategically invested in establishing a state-of-the-art extrusion machinery production base in Shanghai in 1999. Over the years, this has transitioned into our massive Jiangsu manufacturing plant, creating an advanced engineering ecosystem focused on reliability, high efficiency, and safety.
Precision extrusion process modeling, high-efficiency thermal screw dynamics, fully automated close-loop process control, and international safety compliance for hazardous gas ventilation and melt pressure relief systems.
Small extruders (screw diameters ranging from 15mm to 45mm) present unique mechanical challenges. Designing these machines requires a deep understanding of polymer rheology, compression rates, and shear stress management.
For polymers like PA12, PU, and fluoropolymers, the length-to-diameter (L/D) ratio must be meticulously calculated. We deploy 25:1 to 30:1 L/D ratios paired with specialized barrier screw structures to optimize melt homogeneity and prevent un-melted resin exit.
Integrating PLC automation systems (Siemens/Beckhoff) enables real-time synchronization of the screw RPM, vacuum calibration table pressures, belt puller rates, and high-speed cutting units. Close-loop laser diameter measuring guarantees consistency.
Features segmented cast aluminum heaters with integrated cooling fans. Our systems maintain stability inside the barrel to within ±1°C, crucial for processing thermally unstable materials such as medical-grade PVC.
China's manufacturing ecosystem has evolved from high-volume assembly to value-added high-technology machinery production. At BAOD Extrusion, we bring together the cost advantages of Jiangsu's local component supply chain with precision engineering principles developed over decades of research.
Our vertical integration allows us to design and build our own auxiliary machinery, including vacuum calibration cooling tables, belt pullers, and high-speed rotary cutters. This guarantees that all downstream components communicate natively with the central PLC system of the extruder. As a result, we offer seamless system integration at a fraction of the capital investment typically required by European or North American machinery suppliers.
From the rough milling of screw flights to the programming of PLC panels, our 16,000 m² factory handles critical manufacturing steps in-house.
By applying Kingswel Group's original technical specifications and quality inspection procedures, we meet rigorous international standards.
Our on-site engineering team can custom-configure dies, calibration sleeves, and downstream configurations for specialized medical or industrial tubing.
Modern fluid delivery systems in EV automotive architectures demand multi-layer constructions to reduce fuel permeation and increase chemical resistance. BAOD Extrusion develops multi-layer PA (Nylon) hose lines that utilize separate compact single-screw extruders positioned around a unified co-extrusion die block. These lines require precise flow-channel modeling inside the die head to guarantee uniform thickness across all layers, preventing inter-layer delamination even under extreme operational pressures.
Extruding medical catheter tubing with multiple internal chambers (multi-lumen tubing) requires high thermal stability and specialized air tooling. The air pressure in each internal lumen must be controlled independently during the calibration phase. Our High Speed PVC & PU Medical Tube Extrusion Lines operate under cleanroom-compatible parameters, utilizing stainless steel medical-grade vacuum tanks, non-contaminating water circuits, and closed-loop OD and wall thickness monitors.
Replacing traditional EPDM rubber with Thermoplastic Vulcanizates (TPVs) is a major trend in automotive cooling and heating loops. TPVs offer excellent elasticity, heat stability, and are 100% recyclable. Our specialized TPV extrusion lines feature integrated inline knitting stations, allowing polyester or aramid yarn reinforcing layers to be wrapped directly onto the extruded inner tube before the outer protective TPV layer is applied.
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 captured massive attention from global buyers.
In the controlled environment of a modern industrial facility, a single, hair-thin plastic tube wound onto a reel might seem unremarkable to the untrained eye. However, in sectors ranging from mining and quarrying to large-scale infrastructure demolition, this tube—known as a shock tube or detonating tube—is a critical component requiring absolute mechanical reliability.
In the sterile, quiet environment of a modern medical facility, a clinician prepares a complex catheter for a critical procedure. This thin, flexible tube is far more than a simple conduit; internally, it is divided into several microscopic channels, or lumens, each designed to perform distinct, concurrent tasks. BAOD compares technical metrics with European standards to offer comparable tolerances at optimized capital cost levels.
How do the world's most reputable vehicle manufacturers ensure the absolute integrity of every fuel line, brake hose, and cooling pipe buried deep within a vehicle’s chassis? Why has the shift toward electric and lightweight vehicles made the precision of these small-diameter fluid lines more critical than ever? BAOD answers these questions with rigorous QA protocols and automotive certifications.
As the twilight sun reflects off the sleek, aerodynamic curves of a modern electric vehicle parked in a bustling metropolitan street, few observers notice the quiet, critical components ensuring the cabin remains a sanctuary of silence and temperature control. Behind these seals are multi-material co-extrusion technologies developed by BAOD to support the EV transition.
