Explore our industrial-grade, precision-manufactured extrusion machinery line-up.
Macroeconomic drivers and technological evolution in global polymer processing.
The global manufacturing footprint is witnessing a rapid structural shift in the downstream utilization of plastic profiles. Industrially, plastic profile extrusion equipment serves as the backbone for critical sectors including automotive manufacturing, biomedical tubing, telecommunication microducts, and infrastructure piping. According to recent market analysis, the global market for thermoplastic extrusion machinery is experiencing a projected Compound Annual Growth Rate (CAGR) of over 5.4% through 2030, driven by the demand for lightweight materials, multi-lumen micro-extrusion, and eco-friendly bio-based resins.
China has transitioned from a high-volume manufacturing center to a global leader in precision engineering. Jiangsu Baodie Automation Equipment Co., Ltd. (BAOD) stands at the forefront of this industrial transformation. Modern profile and tube extrusion requires a delicate balance of melt-pressure stability, material rheology management, and sub-millimeter precision calibration. Factories are no longer merely assembling mechanical gears; they are engineering integrated IoT-enabled production ecosystems that optimize energy efficiency, reduce raw polymer wastage, and maximize throughput speed.
By integrating closed-loop melt pumps with real-time gravimetric dosing systems, modern extrusion lines maintain minimal dimensional fluctuations (within ±0.02mm) even at high linear speeds.
Utilizing electromagnetic induction heating, our single and twin-screw extruders reduce thermal loss by 30-40% compared to traditional ceramic band heaters, directly improving factory OPEX.
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) founded in 2002, is dedicated to the design, manufacture, and sales of high-performance plastic extrusion equipment. Leveraging over 25 years of engineering experience in designing and fabricating premium-quality machines originally rooted in Taiwan, our parent group (KINGSWEL GROUP) established its manufacturing base in Shanghai in 1999 before expanding into our current state-of-the-art facility in Jiangsu.
Our manufacturing philosophy revolves around custom engineering, high efficiency, and process automation. Over the decades, we have partnered with tier-1 automotive component suppliers, medical device conglomerates, and international telecom companies to deploy turnkey extrusion systems that adhere to the most stringent international standards.

The path toward Industry 4.0 and sustainable thermoplastic extrusion systems.
As polymer sciences advance, the demands on extrusion machinery manufacturers become exponentially complex. The development trajectory is heavily focused on co-extrusion versatility, allowing factories to process multi-layered structures in a single pass. For instance, in automotive applications, fuel delivery hoses require multiple barriers to prevent volatile organic compounds (VOCs) from escaping. Modern lines stack up to 5 or even 7 layers, combining PA, EVOH, and adhesive layers in an integrated die head.
Looking to the future, the integration of AI-driven closed-loop controls will define production efficiency. By constantly parsing data from laser gauges, melt temperature probes, and puller speed sensors, the extruder PLC dynamically adapts raw material feed and screw rpm to eliminate deviation before it manifests in the final product. Additionally, the industrial adoption of recycled polymers (PCR/PIR) necessitates specialized screw profiles that can homogenize materials with fluctuating viscosity levels without degrading mechanical properties.

The precision is determined by four integrated elements: the stability of the raw material feed (gravimetric control), the design of the screw (avoiding excessive shear and localized heating), the design of the vacuum sizing tank (automatic closed-loop vacuum control), and the synchronization of the puller unit. Any minor variation in puller speed instantly translates to dimensional variations in the extruded product.
TPV (Thermoplastic Vulcanizate) contains a dispersed cured rubber phase in a thermoplastic matrix, which exhibits different rheological behavior compared to PVC. TPV requires high-shear screws with a compression ratio typically between 2.5:1 and 3.0:1, and a length-to-diameter (L/D) ratio of 30:1. Precision temperature control is critical to prevent degradation while ensuring a smooth surface finish. PVC processing, on the other hand, requires meticulous formulation control (stabilizers, lubricants) to prevent hydrochloric acid off-gassing and screw corrosion.
Automotive fluids (fuels, coolants, oils) chemically degrade standard polymers. By using co-extrusion, we can place a high-cost barrier polymer (such as EVOH or fluoropolymers) as a thin internal layer, protected by structural outer layers made of PA12 or thermoplastic vulcanizates. This delivers optimal barrier performance and mechanical strength at a optimized material cost.
BAOD's SJ Series single-screw extruders are built with high-grade nitrided steel barrels and screws, optimized via computer simulation for specific polymer families. They incorporate energy-saving motor drives, integrated melt pumps, and user-friendly PLC touchscreen controls that allow seamless integration into automated factory control loops.
Our custom precision vacuum sizing tanks utilize automatic water level and negative pressure controls. By maintaining a constant water temperature via efficient heat exchangers and optimizing water spray distribution, the extruded profile is solidified uniformly. This prevents warping, shrinkage, and internal stress accumulation, which is vital for high-accuracy automotive sealing strips.
