Nonwoven Thermal Calendering Machine

·Integrated Roller System & Industry Standard Leadership
The company is the lead drafter of the industry standard for nonwoven thermal calendering machines, combining in-house roller manufacturing with complete machine design capability. The thermal bonding rollers incorporate a patented surrounding deep-hole heat exchange channel structure enabling full-surface thermal uniformity. Paired with a closed-loop temperature control module, the system maintains full-width temperature differential ≤±0.65℃ and fabric basis weight deviation within ±2.5g/㎡, increasing premium hygiene material yield rates by over 18%.

·Advanced Pressure Control
A servo-hydraulic pressure mechanism with 0–30mm axial cross-axis adjustment compensates for roller deflection under load in real time. Line pressure is infinitely adjustable up to 150N/mm, maintaining constant nip pressure across the entire web width. This eliminates edge tightness, loose edges, and wave wrinkles at speeds up to 800m/min, ensuring consistent bonding strength for both lightweight and heavyweight nonwovens.

·Comprehensive Model Range & Ultra-Wide Customization
Standard configurations cover two-roll, Y-type three-roll uniform, and high-speed wide-width models serving both small-scale production and large-scale industrial lines. Standard working widths are 3600mm and 5400mm, with custom designs up to 7000mm available—one of the few domestic manufacturers capable of delivering ultra-wide thermal bonding equipment.

·Heavy-Duty Frame & Dynamic Balancing
The main frame is constructed from thick steel plate with full stress-relief annealing to eliminate internal stress from welding. Each roller undergoes three-stage dynamic balancing calibration under simulated load to G0.8 grade, ensuring no frame deformation or vibration under 24/7 full-load operation.

·PLC Closed-Loop Control
The proprietary HMI control system integrates temperature, line pressure, and speed parameters in a coordinated loop. Up to 100 process recipes can be stored and recalled for different materials and basis weights, enabling quick changeovers. The system supports remote monitoring and data traceability for EU medical device and automotive interior material production requirements.

Medical and hygiene nonwovens (SMS, spunlace, thermal bond cotton for diaper topsheets, medical bed sheets, mask layers, feminine care products) with consistent softness, tensile strength, and skin-contact safety for Southeast Asian and European hygiene product manufacturers. Geotextiles and industrial filtration felts (polyester needle-punched geotextiles, dust filter fabrics for infrastructure and industrial emission control) with enhanced density and tear strength for Middle Eastern and Latin American infrastructure projects. Automotive interior fiber substrates (roof liners, seat backrest materials) meeting European automotive interior standards for Turkish and Polish automotive parts suppliers. Biodegradable plant-fiber nonwovens (PLA, straw fiber eco-friendly materials) with low-temperature thermal bonding and REACH compliance for European markets. Home textile nonwovens and cleaning cloth substrates (wiping cloths, curtain liners) balancing bulk and durability for Japanese and Korean household brands. Paper and fiber composite board hot-pressing (thick cardstock, wood fiberboard) for packaging and lightweight building material applications.
