Explore our foundational range of precision plastic extrusion equipment, engineered for high productivity, tight tolerance profiles, and resilient runtime profiles under strenuous industrial demands.
Ultra-High-Molecular-Weight Polyethylene (UHMWPE) represents a pinnacle of industrial polymer engineering. Boasting a molecular mass that ranges from 3 to over 6 million g/mol, UHMWPE offers unrivaled impact strength, wear-resistance, and self-lubricating properties. However, this massive molecular weight poses an extraordinary challenge for standard thermoplastic processing equipment: a melt flow index (MFI) approaching zero.
Unlike conventional polyethylene (HDPE, LDPE), UHMWPE does not liquefy to a state that allows typical screw shearing and flow delivery. Traditional single-screw systems attempt to process it, only to experience catastrophic shear heating, polymer chain degradation, and extreme backpressure. Under the hood, the material behaves more like a highly viscous, rubbery gel than a fluid thermoplastic.
To successfully extrude custom UHMWPE profiles, tubes, and sheets, specialized engineering approaches are necessary. At BAOD EXTRUSION, we have developed our proprietary SJ Series Single Screw Extruders and optimized profile lines specifically engineered to mitigate polymer shearing stress, control barrel thermal zones with sub-degree accuracy, and supply continuous high-pressure flow to dedicated profile-forming tooling.
| Processing Factor | Standard Polyolefins | UHMWPE Parameter |
|---|---|---|
| Melt Index (MFI) | 0.5 to 20 g/10 min | < 0.01 g/10 min (Non-flowing) |
| Screw Compression Ratio | 2.5:1 to 3.5:1 | 1:1 to 1.5:1 (Ultra-low shear) |
| Required Extrusion Pressure | 150 to 300 Bar | Up to 800 Bar (Tooling specific) |
| Friction Coefficient | 0.30 - 0.40 | 0.10 - 0.22 (Self-lubricating) |
Modern manufacturing requires equipment that balances high-efficiency extrusion with total process stability. For over two decades, BAOD EXTRUSION has directed R&D initiatives toward resolving mechanical friction, vacuum calibration stability, and automation in high-speed downstream processing.
Optimized screw geometry and high-torque motors allow our systems to yield maximum throughputs at reduced energy-per-kilogram parameters, minimizing structural overhead costs.
Our custom precision vacuum sizing tanks utilize advanced closed-loop pressure feedback to maintain tight tolerance controls over thin-wall profiles and micro-ducts.
Integrated PLC control centers orchestrate synchronization between the single-screw extruder, the high-speed puller systems, and automatic spool-changing coiling machines.
BAOD EXTRUSION (Jiangsu Baodie Automation Equipment Co., Ltd.), founded in 2002, is dedicated to designing, manufacturing, and sales of high-performance plastic extrusion equipment. Based on 18 years of experience in designing and fabricating high-quality machinery in Taiwan, our original parent company (KINGSWEL GROUP) invested in establishing our primary manufacturing base in Shanghai in 1999. Today, we bring a total of 25 years of design pedigree directly to global B2B procurement professionals.
Sourcing large-scale profile extrusion machinery from China requires meticulous evaluation of engineering standards, material sourcing integrity, and component lifespans. As custom UHMWPE profiles replace traditional metals in industrial wear guides, mining troughs, and food production chutes, procurement specialists must prioritize the following metrics:
| Evaluation Parameter | Common Factory Limitations | BAOD EXTRUSION Standard Compliance |
|---|---|---|
| Screw & Barrel Material | Standard nitrided steel (worn rapidly by fillers/high viscosity) | Bimetallic barrels utilizing high-alloy coatings for 3x lifetime expansion. |
| Thermal Control Precision | PID loops with deviation > ±3°C (risking localized polymer burning) | Advanced PLC-driven heating/cooling blocks with a strict ±0.5°C threshold. |
| Drive Train Stability | Under-specified gearboxes experiencing failure under maximum torque | Heavy-duty, high-torque reducers matched with vector-controlled AC drives. |
| Downstream Synchronization | Manual speed adjustment (leading to profile variation during speed changes) | Closed-loop feedback loops linking caterpillar pullers directly to extruder speed. |
The next decade of extrusion machinery relies heavily on digital twin monitoring, machine learning control loops, and the integration of highly challenging post-consumer materials. UHMWPE extrusion will transition from basic slow-speed profile forming into continuous high-precision manufacturing.
By capturing barrel pressure, torque fluctuations, and thermal deviations at millisecond intervals, our software predicts tool wear before quality defects emerge. Sourcing managers can track machine efficiency from remote control offices.
Optimizing mechanical design to allow inline grinding and re-processing of out-of-spec startup profiles without compromising the molecular weight profile of the finished products.
We are advancing the boundaries of flow channels and compression zones within dies. Advanced simulation software is used to design channels that minimize drag, which is essential to prevent internal mechanical stresses in the extruded UHMWPE profiles.
Purchasing machinery from a factory in China requires reassurance of reliable service, localized technical availability, and strict regulatory alignment. At BAOD EXTRUSION, our machinery lines are constructed to align with global B2B expectations.
Every electrical line, safety gate, and emergency stop system conforms to European machinery directives and OSHA safety regulations.
We run Factory Acceptance Tests using your target compound materials, sending full video data, dimensional reports, and sample profiles before shipment.
Experienced technical teams are deployed globally to manage installation, calibrate machinery control loops, and train localized machine operators.
Critical mechanical and electrical spares (including Siemens PLCs, Omron thermoregulators, and custom heaters) are stocked for rapid global delivery.
