Known interchangeably as Filter Bag Heat Sealing Machine and PTFE Tape Welding Equipment, this specialized manufacturing tool addresses the critical challenge of creating durable, high-temperature seams in industrial filter bags. Unlike conventional sewing machines that create pinholes and weak points, this automated system uses controlled heat and pressure to bond PTFE or aramid tapes to filter media, producing hermetic seals that withstand extreme temperatures and chemical exposure.
Equipped with precision temperature controls (200–400°C) and servo-driven tape feeding, the machine achieves welding speeds up to 15 m/min—3x faster than manual taping while maintaining consistent seal quality. Its modular design accommodates various tape widths (10–50mm) and filter materials (aramid, PTFE, glass fiber), making it indispensable for manufacturing high-performance filter bags used in incineration, metal smelting, and chemical processing.
• Temperature Control: Digital PID controller with ±1°C accuracy (Omron E5CC) ensures precise heat application, critical for bonding heat-sensitive materials like PTFE (melting point 327°C).
• Pressure Regulation: Pneumatic roller system with adjustable pressure (0.2–1.0 bar) creates uniform bond strength across varying material thicknesses (300–1200g/m²).
• Tape Compatibility: Handles PTFE, aramid, and glass fiber tapes with adhesive or heat-activated backings, supporting tape thicknesses from 0.1mm to 0.5mm.
• Speed and Throughput: Produces up to 450 linear meters of sealed seams per hour, with batch programming for consistent production runs.
• Material Handling: Servo-driven feed system with optical edge alignment ensures tape placement accuracy within ±0.5mm, reducing material waste by 15%.
• Safety Features: Dual interlock safety guards, emergency stop buttons, and heat shields meet CE EN 60204 safety standards, protecting operators from thermal hazards.
This High Temp Tape Sealer is essential in manufacturing filter bags for extreme environments:
• Incinerator Filter Production: Sealing PTFE-coated glass fiber bags used in hazardous waste incinerators (260°C operating temp), ensuring seams resist acid corrosion.
• Metal Smelting Filters: Bonding aramid tapes to meta-aramid filter bags, creating seams that withstand 218°C temperature spikes during aluminum smelting.
• Chemical Plant Filters: Sealing PPS filter bags for sulfuric acid production, where welded seams prevent chemical ingress (tested to 1000 hours in 30% H₂SO₄).
• Power Generation: Manufacturing biomass boiler filters with glass fiber tapes, ensuring seams maintain integrity in 200°C flue gases with sulfur dioxide content.
Compared to sewing and manual taping methods, this automated sealer offers transformative benefits:
• Seam Durability: Welded seams maintain 90% of original strength after 500 thermal cycles (20°C to 200°C), vs. 50% for stitched seams (per ASTM D5034).
• Production Efficiency: 300% faster than manual taping, reducing labor costs by 60% for high-volume manufacturers (e.g., 10,000+ bags/week).
• Quality Consistency: Eliminates human error in tape application, reducing reject rates from 8% (manual) to <1% (automated).
• Material Savings: Precision tape placement reduces waste by 20%—saving 0.50–1.00 per bag for PTFE tape ($50/m).
Our tape sealer customization ensures compatibility with specific manufacturing requirements:
• Process Analysis: Engineers evaluate filter material type, thickness, and production volume to recommend optimal roller configuration and temperature settings.
• Machine Configuration: Customizable tape unwinding stations (1–3 stations) for multi-tape applications, with optional laser guide for complex seam patterns.
• Integration Options: Can be integrated with existing production lines (e.g., SY-700-X sewing line) via conveyor systems and PLC communication (PROFINET protocol).
• Testing and Calibration: On-site commissioning includes seal strength testing (ASTM D1002) and production run validation to achieve ≥20N/cm seam strength.
• Training and Support: 2 days of operator training on parameter adjustment and maintenance, with remote diagnostics capability for troubleshooting.
