Nonwoven Calendering Machine Supplier

Thermal bonding systems built around the roller

Changzhou Wujin Guangyu Embossing Roller Machinery Co., Ltd. is a Nonwoven Calendering Machine Supplier that designs and builds complete thermal calendering machines together with the precision rollers inside them. We led and compiled the national industry standard for nonwoven fabric hot-rolling mills, and we manufacture roller blanks, laser-engraved surfaces and hard chrome plating in-house, so the machine package and its bonding rollers are engineered as one system.

Our thermal calendering range is used for adhesive-free consolidation of spunbond, spunlace, ES fiber, geotextile and biodegradable fiber nonwovens. The systems operate through coordinated heat and pressure to deliver controlled bonding strength, softness and surface uniformity across hygiene, medical, geotextile, automotive interior and filtration material production.

Available machine range

We supply seven thermal bonding machine configurations, from compact two-roll units to ultra-wide high-speed systems. Standard working widths are 3600mm and 5400mm, with custom designs up to 7000mm.

Process and application fit

Thermal calendering changes the physical structure of a nonwoven web by melting the low-melt component or softening the fiber surface under controlled heat and pressure. Because no chemical binder is introduced, the process suits skin-contact hygiene materials and environmentally regulated products.

• Medical and hygiene nonwovens - SMS, spunlace and thermal bond cotton for diaper topsheets, medical bed sheets, mask layers and feminine care products.
• Geotextiles and industrial filtration felts - polyester needle-punched geotextiles and dust filter fabrics requiring higher density and tear strength.
• Automotive interior fiber substrates - roof liners, seat backrest materials and acoustic components with controlled thickness and surface quality.
• Biodegradable plant-fiber nonwovens - PLA, straw fiber and other eco-friendly materials processed with low-temperature thermal bonding.
• Home textile and cleaning cloth substrates - wiping cloths, curtain liners and wipes that need a balance of bulk, softness and durability.
• Paper and fiber composite board hot-pressing - thick cardstock, fiberboard and lightweight building material applications.

Engineering value from roller blank to full machine

The main advantage of working with Guangyu is that the calendering machine and its rollers come from the same factory. Our 120,000m² industrial park supports annual production of more than 20,000 precision rollers and 800 embossing or calendering machines, with roll blank finish machining, CNC precision grinding, mirror polishing, laser texturing and hard chrome plating all completed in-house.

Thermal bonding rollers use a patented surrounding deep-hole heat exchange channel structure. Combined with a closed-loop temperature module, this design keeps full-width temperature differential at or below ±0.65°C and fabric basis weight deviation within ±2.5g/m². The stress-relieved heavy-gauge frame and three-stage dynamic balancing to G0.8 grade support continuous 24/7 operation without vibration or frame deformation.

During machining, our in-house deformation analysis system predicts how large structural components will behave, allowing process corrections before parts are finished. This is the manufacturing foundation behind the tight nip, thermal and speed tolerances our machines are specified to hold.

Controls, integration and installation

Every machine is delivered with a PLC closed-loop control system that coordinates temperature, line pressure and speed. The HMI stores up to 100 process recipes for different materials and basis weights, enabling fast changeovers, and supports remote monitoring and data traceability for EU medical device and automotive interior material production.

A servo-hydraulic pressure mechanism provides infinitely adjustable line pressure up to 150 N/mm, with 0-30mm axial cross-axis adjustment that compensates for roller deflection in real time. This eliminates edge tightness, loose edges and wave wrinkles, even at maximum line speeds.

For line integration, we configure the machine around your existing equipment or supply it as part of a complete system. Our Nonwoven Finishing Line and Nonwoven Slitting Machine are designed to match the same web path and control interface. Standard installation parameters include a maximum unwind roll diameter of Φ2500mm, a working temperature range of 120-280°C, closed-loop thermal oil heating and a flow channel pressure of 2.0MPa.

Quality assurance and acceptance

Our manufacturing quality system is ISO 9001 certified, our products carry CE marking and the company is EU RoHS compliant. The national industry standard for Nonwoven Fabric Hot-Rolling Mill was led and compiled by Guangyu, and our equipment is exported to more than 50 countries and regions.

Before shipment, each machine undergoes function testing of the temperature, pressure and speed control loops, roller assembly inspection and dynamic balancing verification. We provide the operating and maintenance documentation needed for your acceptance run, and our standard warranty is 18 months with lifetime technical support.

Information we use to configure your solution

To prepare an accurate configuration and quotation, we need the working point of your line and the target product specification. The following details define the machine design:

• Nonwoven type, fiber composition, basis weight and target bonding strength
• Required working width, maximum line speed and available floor space
• Working temperature range and whether standard thermal oil heating is suitable
• Required line pressure for the material, including lightweight and heavyweight extremes
• Unwind and rewind configuration, roll diameters and web path direction
• Need for embossing, mirror finish, matte finish or other roll surface treatments
• Control interface requirements: standalone PLC, line-integrated SCADA, MES data reporting or remote diagnostics
• Site utilities such as power supply, plant air, thermal oil system and cooling capacity
• Product compliance requirements such as EU medical device, REACH or automotive interior standards
