Founded in 2002, BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) has dedicated over two decades to the design, manufacturing, and global distribution of high-performance plastic extrusion downstream systems. Building upon 18 years of pioneering engineering legacy inherited from our original Taiwan-based parent group, the KINGSWEL GROUP, we established a state-of-the-art manufacturing core in Shanghai in 1999, subsequently expanding to our modern facilities in Jiangsu.
We target four core technological pillars in extrusion design:
Years of Extrusion Innovation
Modern Manufacturing Footprint
Highly Skilled Engineers & Staff
In modern plastics processing, the extruder itself determines the melt quality, but the **downstream equipment** determines the final product's dimensional accuracy, physical characteristics, and overall profitability. As industries shift from commodity profiles to high-precision engineering materials (like TPV, PA12, Fluoropolymers, and UHMWPE), downstream mechanical stability is the defining factor for international compliance.
Historically, extrusion operations suffered from lag in speed synchronization between pullers and extruders, resulting in wall-thickness variation. Modern downstream components utilize closed-loop digital feedback networks, linking laser OD gauges directly with puller drives and vacuum calibration valves. This ensures that even under variable high-speed extrusion conditions, tolerances are held to under ±0.02 mm.
Jiangsu Baodie's R&D efforts are focused on bridging the gap between high-speed material output and downstream handling precision:
By applying real-time EtherCAT fieldbus protocols, the delay between the haul-off puller speed adjustments and the extruder screw rpm is reduced to less than 1.5ms. This prevents the "draw-down ratio" anomalies that cause micro-fractures in structural automotive tubing.
The rise of Electric Vehicles (EVs) demands lightweight materials and multi-layer cooling lines. Thermal management systems rely on TPV (Thermoplastic Vulcanizates) for flexibility and heat resistance. The downstream extrusion line must calibrate, knit reinforcing fabric, and extrude secondary layers in a seamless continuous process.
For multi-lumen catheters used in minimally invasive surgeries, zero contamination and strict concentricity are non-negotiable. Downstream equipment must be operated in cleanrooms, requiring stainless steel contact surfaces, oil-free vacuum pumps, and high-speed rotary cutters that operate without emitting particulates.
The rollout of global 5G fiber networks relies heavily on HDPE silicone core tubes. Co-extruded with an inner lubricious silicone layer, these microducts must survive high blow-in pressures. BAOD's high-speed corrugated forming and auto-traverse winding lines ensure these ducts are fabricated with uniform wall thickness and spooled in lengths up to several kilometers without tangles.
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 attracted massive international attention.
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 detonating tube—demands flawless manufacturing compliance.
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 a distinct role.
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? We look deep into how the shift toward electric and lightweight vehicles makes downline precision critical.
