Explore our high-performance customized single screw extruders, high-speed pullers, and intelligent winding equipment designed to achieve strict dimensional tolerances.
In the modern manufacturing era, the global demand for high-performance elastomers—such as Thermoplastic Vulcanizates (TPV), Thermoplastic Elastomers (TPE), Thermoplastic Polyurethanes (TPU), and various engineering silicone rubbers—is expanding rapidly. As industries shift from traditional thermoset rubbers toward lighter, recyclable, and process-efficient materials, the technological requirements for extrusion machinery have become highly stringent.
Today's automotive, aerospace, and medical engineering sectors demand profiles and tubes with micro-scale dimensional accuracy. A critical driver for this shift is the pursuit of fuel efficiency, noise reduction (NVH), and chemical resistance in demanding environments. Standard extruder designs often struggle to process elastomers due to their unique viscoelastic properties, high melt sensitivity, and tendency to degrade under high shear conditions. Consequently, modern factories require sophisticated screw profiles, precise thermal management, and reliable downstream calibration to ensure uniform physical properties across production batches.
"The successful extrusion of modern thermoplastic elastomers depends heavily on minimizing internal stress and maintaining optimal melt stability. Achieving uniform wall thickness and concentricity requires a highly integrated production line, from gravimetric feeding systems to high-stability vacuum sizing tanks."
As the manufacturing core of Asia, China has evolved from a supplier of basic industrial machinery into a global leader in high-precision, highly automated extrusion lines. Jiangsu Baodie Automation Equipment Co., Ltd. (BAOD EXTRUSION) has been at the forefront of this evolution, merging advanced manufacturing concepts with optimized mechanical design to supply global enterprises with turnkey systems that compete directly with European standards.
The core of any successful elastomer extrusion process lies within the extruder barrel and screw geometry. Processing TPV, TPU, or soft PVC presents unique challenges: these materials exhibit distinct melting behaviors and are highly sensitive to thermal degradation. Standard single screw extruders often fail to provide the necessary thermal homogeneity, resulting in surface imperfections, poor dimensional control, and uneven physical strength.
BAOD EXTRUSION addresses these issues through proprietary screw designs. By optimizing the length-to-diameter (L/D) ratios (typically ranging from 28:1 to 33:1) and customizing the compression zones, our SJ Series extruders ensure gentle melting and uniform shear rates. Barrier screws combined with distributive mixing elements are utilized to homogenize the melt without raising temperature levels above the polymer’s degradation threshold.
Furthermore, precise melt pressure is crucial. The integration of high-performance melt pumps and closed-loop control systems stabilizes output pressure, absorbing pressure fluctuations from upstream feeding. This precise control is critical when manufacturing thin-walled medical tubing or multi-lumen catheters, where even a minor variation in melt pressure can lead to out-of-tolerance parts.
Dedicated to Excellence in Plastic Extrusion Since 2002
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) was established in 2002, specializing in the design, manufacturing, and distribution of high-end plastic extrusion machinery. Leveraging 18 years of design and fabrication experience inherited from our Taiwanese parent company (KINGSWEL GROUP), we established a robust production base in Shanghai in 1999 before expanding our operations in Jiangsu.
With 25 years of continuous research and development in plastic extrusion technology, our team focuses heavily on precision extrusion technology, high-efficiency processing systems, high levels of automated process control, and comprehensive safety features for our equipment.
Engineered systems configured to meet specific demands for automotive profile shaping, medical tube extrusion, and multi-layer structural piping.
Elastomer products are critical to structural performance across multiple major industries. BAOD EXTRUSION provides engineered systems tailored to these specific manufacturing sectors:
Automotive Sealing Systems (TPV/PVC/EPDM): Modern automotive body seals, glass run channels, and dynamic door seals require complex co-extrusion profiles. Our machinery supports multi-durometer extrusion (combining rigid carriers with soft sealing bulbs and optional metal-insert integration) to produce weatherstrips that minimize vehicle cabin noise.
Medical-Grade Fluid Delivery (TPU/PVC/Silicone): Single-lumen and multi-lumen tubing used in clinical settings must meet strict requirements for cleanroom compatibility, biocompatibility, and dimensional stability. Our high-speed medical tube extrusion lines feature closed-loop laser gauge feedback to monitor outer/inner diameters and wall thickness at high line speeds, ensuring compliance with medical regulatory frameworks.
Telecommunications & Infrastructure (HDPE/Silicone): Silicon core micro-ducts are widely used in fiber optic installations. These ducts rely on co-extrusion technology to place a friction-reducing inner silicone layer inside a robust HDPE outer sheath, enabling long-distance fiber blowing.
Deploying complex capital equipment globally requires adherence to international standards. BAOD EXTRUSION builds machinery in compliance with CE marking requirements, UL electrical standards, and ISO 9001:2015 quality management principles. This ensures that our extrusion lines integrate into manufacturing facilities in Europe, North America, and other regulated markets.
We manage the deployment process from engineering design through commissioning. Our localization strategy includes:
The extrusion industry is transitioning toward Industry 4.0 paradigms, and BAOD is aligning its development roadmap with these trends. Our engineering focus centers on:
Developing inline calibration tables that adjust vacuum chamber pressures and cooling temperatures dynamically based on laser scanner gauge readouts.
Expanding the use of permanent magnet synchronous motors (PMSM) and electromagnetic induction heating barrels to reduce electricity consumption by 20-30%.
Designing sophisticated crosshead dies that support up to five distinct material layers, optimizing barrier property distribution in automotive fuel systems.
Detailed answers to key engineering and procurement questions regarding our custom elastomer processing lines.
Our SJ Series extruders utilize custom barrier screws designed for low-shear, uniform melting. We isolate temperature control zones along the barrel using high-precision ceramic or electromagnetic heaters paired with cooling blowers, maintaining temperatures within ±1°C of the set point.
Yes. We configure complete co-extrusion systems including multiple extruders (often combining our SJ45, SJ65, or SJ75 models) feeding into a single, custom-designed co-extrusion die head. We can also integrate metal strip or fiberglass reinforcement systems directly into the profile head.
We combine a high-stability vacuum sizing tank with closed-loop laser outer-diameter monitoring and ultrasonic wall-thickness gauges. The puller speed and vacuum levels adjust automatically based on real-time dimensions to keep tolerances within ±0.02mm.
Every machine is shipped with a built-in Ethernet gateway for secure remote support. Our technical team can access the Siemens PLC to troubleshoot sensors, adjust control parameters, or upload custom recipes, supplemented by video consultations and onsite field engineering services.
Yes. We standardize our electrical and pneumatic systems on internationally recognized brands, including Siemens PLCs and touchscreens, Omron temperature controllers, Schneider switchgear, ABB or Delta frequency inverters, and Yuken hydraulics. This simplifies component sourcing for global maintenance teams.
