Explore our industrial-grade processing lines engineered for maximum throughput, low energy consumption, and high repeatability.
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.) founded in 2002, is dedicated to the design, engineering, and global distribution of high-performance plastic extrusion systems. Drawing upon over 25 years of foundational precision engineering expertise inherited from Taiwan, the original parent entity (KINGSWEL GROUP) established our strategic production facility in Shanghai in 1999 to support international plastic processing demands.
Our operational philosophy integrates rigorous quality controls with innovative machinery development to solve the complex physics associated with processing highly viscous engineering thermoplastics like Polypropylene (PP).
Navigating the rheological and mechanical limits of Polypropylene for high-performance industrial profiles.
Polypropylene (PP) possesses a semi-crystalline structure that exhibits narrow processing windows and significant die swell. Our customized single-screw and twin-screw extruders leverage custom-calculated L/D (Length/Diameter) ratios of 28:1 to 33:1. By incorporating barrier flights and intensive mixing segments, our systems homogenize the PP melt, preventing local shear heating and reducing molecular weight degradation.
PP's high shrinkage rates (often between 1.5% to 2.5%) present unique dimensional challenges. BAOD's precision vacuum sizing calibration tables utilize CNC-machined, multi-stage sizing sleeves and high-vacuum chambers. Through digital closed-loop water temperature and vacuum pressure monitoring, we guarantee profiles with linear dimensional tolerances below ±0.05 mm, mitigating thermal warping.
The industry's technical trajectory points toward multi-material and cellular profiles. Our co-extrusion technology enables manufacturers to fuse rigid PP structural cores with soft, elastomeric PP/TPV sealing lips or micro-foamed PP layers. This reduces weight by up to 30% without sacrificing structural integrity, meeting modern automotive and lightweight construction benchmarks.
Unlocking cross-industry capability with specialized configurations for diverse structural applications.
Modern vehicles demand highly durable, non-toxic sealing strips. PP profiles modified with EPDM or TPV (Thermoplastic Vulcanizates) provide exceptional weatherability, UV resistance, and noise insulation. Our extrusion lines integrate downstream continuous knitting, reinforcement tape application, and inline cutting systems to manufacture complex automotive sealing structures at high speeds.
Polypropylene is widely replacing PVC in construction due to its eco-friendly recycling profile and superior chemical resistance. Our lines extrude thermal break strips, cable routing conduits, and protective edge trims. Equipped with high-output motors and wear-resistant bimetallic barrels, these machines comfortably process filled PP compounds (such as glass-fiber or talc-filled formulations).
For cleanroom environments, our specialized medical-grade extrusion lines feature stainless steel structures, oil-free vacuum pumps, and specialized cooling channels. They process medical PP/PVC tubes and multi-lumen profiles with zero contamination risk. Digital controls ensure full compliance with FDA and ISO 13485 standards.
Operating a 16,000 m² state-of-the-art facility in Jiangsu, BAOD Extrusion combines highly optimized assembly pipelines with advanced component integration. This enables us to provide cost-effective extrusion lines without compromising component quality.
Our supply chain ecosystem utilizes standardized, internationally serviceable components: Siemens PLC human-machine interfaces, ABB inverters, Omron PID temperature controllers, and premium bimetallic screws. This means spare parts are easily sourceable anywhere in the world.
By executing localized machining, heavy frame welding, and final precision assembly under one roof, we achieve significant overhead reduction. These savings are passed on to global buyers as lower Total Cost of Ownership (TCO) and faster lead times compared to standard European machinery manufacturers.
Essential criteria for evaluating PP profile extrusion line manufacturers and ensuring long-term OEE.
Verify if the extruder features gravimetric dosing systems that continuously measure material mass flow rate. For PP profiles, particularly those incorporating regrind or masterbatch, precise feeding prevents fluctuations in melt pressure and dimensions.
A high-quality line must feature closed-loop communication between the belt puller (haul-off) and the extruder screw. If the puller speed deviates even by 0.1%, it results in uneven wall thickness. Ensure the line utilizes high-response AC servo motors for haul-off.
The extrusion die must be engineered with computational fluid dynamics (CFD) mold flow analysis. A poorly designed die creates dead zones where PP can degrade, leading to yellowing, structural weak points, and poor surface finish.
Purchasing machinery internationally requires thorough regulatory compliance and responsive support systems. BAOD Extrusion ensures that every custom PP profile extrusion line conforms to target market safety and electrical standard frameworks:

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 drew global procurement 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 to infrastructure demolition, this tube—known as a shock tube—demands absolute wall thickness reliability and zero structural voids.
In sterile medical environments, a clinician prepares a complex catheter. Internally, this tube is divided into several microscopic channels, or lumens. Discover how BAOD maintains dimensional stability comparable to European standards at optimized industrial price points.
