Explore our top-tier precision hardware engineered for rigorous industrial demands, featuring optimized screw designs for complex polyamides, high-speed pullers, and intelligent co-extrusion technology.
Polyamide 6 (PA6, Nylon 6) is highly valued for its mechanical robustness, outstanding thermal stability, and superior resistance to chemical solvents and wear. Industrially, PA6 is extensively processed via extrusion profiles, tubes, and multi-layer corrugated structures. Modern manufacturing sectors demand strict dimensional stability, high throughput rates, and long-term running reliability.
In global automotive engineering, PA6 extrusion systems are critical in producing multi-layer fuel lines, vacuum braking systems, and powertrain conduits. When compared to conventional metals or lower-performance plastics, PA6 delivers weight savings that directly help auto OEMs satisfy modern fuel economy and carbon reduction mandates. Because of this, global demand for highly automated, high-output PA6 extrusion technology has grown rapidly.
Sourcing from advanced China PA6 extrusion factories gives global buyers an ideal balance of cost efficiency, mechanical precision, and fast custom engineering. By using integrated downstream equipment, smart melt control pumps, and customized screw designs, manufacturers can achieve tight tolerances that match or exceed strict European standards.
BAOD EXTRUSION specializes in precision extrusion designs. Over the decades, our engineers have developed proprietary technologies focused on four key areas:
Founded in 2002, BAOD EXTRUSION is dedicated to designing, manufacturing, and sales of high-performance plastic extrusion equipment.
Based on 18 years of experience in designing and fabricating high-quality machinery in Taiwan, the original parent company (KINGSWEL GROUP) established an extrusion manufacturing base in Shanghai in 1999. Decades of engineering research and field testing have helped BAOD EXTRUSION develop reliable systems for the global market, serving industries that require high precision and durability.
With a production facility in Jiangsu, BAOD continues to advance the limits of plastic extrusion technology. We develop specialized tooling and machinery for demanding materials like PA6, fluorine plastics, and multi-layer composites.
Learn More About BAODExtruding Polyamide 6 (Nylon 6) requires careful temperature control and customized mechanical configurations. Because PA6 is highly hygroscopic and susceptible to thermal degradation, standard single-screw extruders are not sufficient.
PA6 absorbs ambient moisture quickly, which can cause hydrolytic degradation at extrusion temperatures (220°C–260°C). This degradation lowers molecular weight and reduces physical properties. To prevent this, raw PA6 must be dried to a moisture content under 0.05% using desiccant dryers with a dew point below -40°C.
We utilize a 28:1 to 32:1 L/D ratio with custom barrier screws. This design provides uniform melting at low shear rates, avoiding local overheating that can break down molecular chains. Mixing sections ensure colorants and additives disperse evenly without causing structural flaws.
PA6 exhibits high crystallization shrinkages. Proper cooling calibration is key. Using a closed-loop vacuum calibration tank with multi-stage water spray setups allows BAOD systems to control tube outer diameters (OD) and circularity profiles accurately.
BAOD designs customized extrusion setups for complex industrial applications, ensuring production runs remain stable over long periods.
Modern vehicles use multi-layer lines (e.g., PA6/EVOH/PA12) to limit fuel vapor emissions. BAOD co-extrusion technology produces clean layers with strong adhesion, meeting international automotive safety standards.
In machinery and infrastructure, PA6 corrugated pipes shield wiring from heat and chemical wear. Our high-speed single-wall corrugating forming lines shape profiles cleanly even at maximum line speeds.
Catheter lines and diagnostic tubes require clean, biocompatible raw materials. BAOD medical-grade cleanroom extrusion setups deliver consistent dimensions with tight tolerances for demanding healthcare applications.
Our design and build workflow ensures each system delivers high repeatability and minimal downtime.
We analyze the rheological behavior of the customer's resin to customize the screw compression ratio and feed zone layout.
Critical parts like extruder barrels, screws, and dies are machined in-house on high-precision CNC equipment to guarantee tight tolerances.
We integrate smart sensors, Siemens PLC modules, and closed-loop control systems to monitor temperatures and pressures in real time.
Before shipping, each line is assembled and run under production conditions to verify throughput rates and product quality.
For global buyers, purchasing equipment from abroad requires trust in design standards, electrical safety, and long-term service support.
BAOD EXTRUSION operates under an ISO 9001:2015 certified quality management system. All electrical components, wiring layouts, and pressurized vessels meet CE standards. We use components from global brands like Siemens, Omron, ABB, and Schneider, ensuring replacement parts are easy to source locally.
To support our international customers, we offer comprehensive installation assistance, operator training, and remote troubleshooting. Our field service engineers travel globally to ensure new lines are commissioned quickly and run reliably.
