Polypropylene (PP) small diameter tubes serve as vital conduits across modern automation, automotive fuel and air pathways, pneumatic delivery systems, and specialized medical apparatuses. Driven by the global push for lightweight structures and high-performance engineering plastics, precision in small-diameter tube manufacturing has transformed from simple dimensional forming into an advanced discipline of viscoelastic control and high-speed mechanical synchronization.
For industrial procurement leads, optimizing product output translates directly to optimizing thermal behavior inside the extruder. Because PP demonstrates high crystallinity and sharp shear thinning properties, precise heating profiles, coupled with specialized screw geometries, are vital. Jiangsu Baodie Automation Equipment Co., Ltd. addresses this technical challenge by engineering systems designed specifically for low-shear, highly homogeneous melt output, ensuring consistent wall-thickness tolerance to within ±0.02 mm.
The demand shift toward electric vehicles (EVs), minimal-invasive medical surgeries, and integrated smart manufacturing has accelerated the reliance on micro-tubes. High-precision PP tubes must withstand extreme environmental strains while retaining strict flexibility metrics.
Founded in 2002, BAOD EXTRUSION is dedicated to designing, manufacturing, and sales of high-performance plastic extrusion equipment. Our engineering DNA traces back to 18 years of design and fabrication experience of high-quality machinery in Taiwan. The original parent company (KINGSWEL GROUP) made a strategic decision to invest and establish a main extrusion manufacturing hub in Shanghai in 1999, which later grew into our present state-of-the-art facility in Jiangsu.
Throughout decades of industrial operation, BAOD has targeted the high-precision market segments. We maintain a relentless R&D focus on:
Designed for clean-room applications, automotive tubing, and medical device parts featuring high stability and closed-loop control.
Provides high chemical barrier layers for fuel and fluid management, ensuring zero leakage and long operational lifetimes.
Achieves optimal run rates of medical-grade tubing under clean, dust-free manufacturing environments with extreme sizing precision.
Continuous high-output forming technology for flexible protective conduits in wiring harnesses and thermal systems.
Engineered for structural reinforcement layers, combining thermopolymers with high-strength knitting fabric interfaces.
Delivers co-extruded sealing components with high elastic recovery, low friction coefficients, and sound isolation properties.
Specially designed L/D ratios of 28:1 to 33:1 configured for high-viscosity PP polymers. The customized barrier screw guarantees zero thermal degradation while maintaining a highly homogeneous melt output under minimal shear stress.
Multi-chamber vacuum systems with high-accuracy temperature controls (within ±0.5°C). Prevents internal stress development, mitigating downstream shrinkage of the PP tube and guaranteeing roundness.
Tension-free caterpillar pulling synchronized with rotary flying knives. Provides smooth, burr-free cuts on ultra-thin walls without mechanical deformation or internal crack propagation.
Ultrasonic measuring heads integrated with continuous gravimetric dosing. The control loop auto-adjusts screw speeds and puller tension instantly to maintain critical outer-diameter and inner-diameter parameters.
To serve automotive, medical, and aerospace tier-one suppliers in North America, Europe, and the APAC region, Jiangsu Baodie Automation Equipment Co., Ltd. builds machinery conforming to demanding global design directives:
We understand that down-time on high-volume extrusion lines is extremely costly. BAOD provides global, responsive engineering support through a multi-tier localized scheme:
Integrated industrial routers allow our main engineering team to execute real-time troubleshooting, sensor diagnostics, and PLC updates instantly.
Dedicated commission technicians perform physical installations, custom calibration routines, and train facility teams on optimal operational standards.
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...
