Extrusion Feeding Pump XN-EFP

Name: Extrusion Feeding Pump XN-EFP

Equipment Type: Stepper-Motor-Driven Extrusion Feeding Pump for Slot-Die Coating & Film Extrusion

Product Code: XN-EFP

Product Introduction:

The Extrusion Feeding Pump XN-EFP is designed to provide stable and precise material supply for slot-die coating and film extrusion processes. The system delivers controlled flow of slurry or liquid materials and is suitable for laboratory-scale coating, dispensing, and extrusion applications requiring high flow accuracy and repeatability. The XN-EFP is designed to be synchronized with downstream slot-die applicators or other coating equipment for inline coating workflows.

Main Features:

• Stepper-motor-driven lead screw — ensures precise and adjustable flow rate control
• Compatible with coating equipment — can be synchronized with coating machines to accurately match material supply requirements
• Supports continuous and stable extrusion — minimizes pulsation and improves coating uniformity
• Quick-change syringe design — enables easy replacement and cleaning between runs
• Multiple syringe sizes — 20 mL, 30 mL, and 50 mL PP syringes supported as standard
• PTFE tubing included — outer diameter 3.2 mm, inner diameter 1.6 mm, chemically resistant to NMP and aqueous slurries
• Compact structure with refined industrial design — suitable for laboratory benchtop use
• Simple operation and reliable performance for research and pilot-scale applications

Application Areas:

• Slot-die coating slurry supply — controlled material delivery to slot-die applicators (XN-SDC, XN-FAS-100)
• Film extrusion — laboratory-scale film extrusion processes requiring stable feed
• Dispensing applications — precision dispensing of slurry or liquid materials
• Battery electrode coating research — synchronized slurry supply with automatic film coaters for repeatable cathode/anode coating
• Coating research and pilot-scale processes where flow accuracy and repeatability are required
• Multi-fluid coating studies — multiple XN-EFP units can be paralleled for sequential or simultaneous material supply

Recommended Operating Procedure:

1. Place the XN-EFP on a stable laboratory benchtop with adequate working space and good lighting; connect the power supply per local electrical standards (120 W). 2. Power on the XN-EFP and verify that the stepper motor, lead screw, and touch screen control are operating normally. 3. Select the appropriate PP syringe size (20, 30, or 50 mL) based on the volume of slurry required for the run. 4. Load the slurry into the syringe; ensure no air bubbles are trapped in the syringe barrel or the PTFE tubing (OD 3.2 mm / ID 1.6 mm). 5. Mount the loaded syringe in the quick-change holder and secure. 6. Connect the PTFE tubing outlet to the slot-die applicator inlet or other coating equipment material inlet. 7. Set the target flow speed (within 0.05–5 mm/s plunger speed) and stroke length (up to 100 mm) on the touch screen control panel. 8. If synchronizing with a coating machine, configure the synchronization mode according to the included user manual. 9. Initiate the extrusion run; the stepper motor advances the syringe plunger at the configured speed to deliver continuous, stable material supply with minimal pulsation. 10. After the run, retract the plunger, remove the syringe, and clean the syringe and PTFE tubing with appropriate solvent (water or NMP, depending on the slurry system used). 11. Dry all wetted-surface components thoroughly before storage.

Maintenance:

• Frequently wipe the machine with a soft cloth dampened with alcohol to keep it clean
• Lubricate the lead-screw mechanism per the included user manual to maintain smooth movement
• If the machine will not be used for an extended period, wipe down the surface of moving components and apply a protective rust-prevention oil
• Periodically inspect screws, nuts, pins, and other fasteners across all parts of the machine to prevent loosening
• Inspect the PP syringes for cracks or damage before each run; replace if compromised
• Inspect the PTFE tubing for chemical attack, kinks, or blockages; replace as needed for consistent flow

Packaging & Storage:

The XN-EFP ships fully assembled with the stepper-motor drive, lead-screw mechanism, quick-change syringe holder, touch screen control panel, PTFE tubing (OD 3.2 mm / ID 1.6 mm), and standard PP syringes (20/30/50 mL). Store on a stable laboratory bench or workstation in a clean, dry environment, away from heat sources, direct sunlight, and corrosive atmospheres. Disconnect the power supply when the equipment is not in active use. After each use, clean the syringe holder, PTFE tubing, and any wetted-surface components with appropriate solvent and dry thoroughly before storage. Inspect the lead-screw mechanism, stepper motor, and quick-change syringe holder periodically for wear or contamination.

Safety:

For research and industrial laboratory use only. Keep hands clear of the moving syringe plunger, lead-screw mechanism, and stepper-motor drive during operation to prevent personal injury. Operation by two or more persons simultaneously is not allowed to avoid accidental injury. External (third-party) technical personnel and unauthorized persons must not disassemble the equipment under any circumstances. Always wear appropriate PPE (safety glasses, chemical-resistant gloves, lab coat) when handling slurries, solvents, and coated substrates. When working with NMP-based slurries or other regulated solvents, operate in a well-ventilated fume hood and follow local regulations on solvent use and recovery — NMP and similar aprotic solvents have specific exposure limits under OSHA, EU REACH, and other regional safety frameworks. When handling pressurized slurry in the PTFE tubing, ensure all tubing connections are properly secured before initiating the extrusion run; tubing rupture or disconnection under pressure can cause splashing of slurry or solvent. Disconnect the power supply before any cleaning, maintenance, or component replacement. Refer to the included user manual for complete safety and operating instructions.

Note: Specifications listed above are typical and for reference only. Actual performance depends on the specific slurry chemistry, viscosity, syringe size, tubing length, downstream coating equipment configuration, and operator technique — consult published literature and our technical team for guidance on specific feed-and-coating protocols.
