In 2026, a product that attracted widespread attention in the field of composite equipment-Yonggao tension-free PUR hot melt adhesive laminating machine was born.
Dongguan Yonggao Machinery has been deeply engaged in the research and development and manufacturing of composite equipment for more than 40 years. It has always focused on the production pain points of the industry, adhered to the core research and development concepts of efficiency, stability, and innovation, and continued to iteratively upgrade composite production equipment.
Based on the current lamination problems of light and thin elastic fabrics in the textile, automotive interior, and home textile industries, as well as long-term feedback from customers about common industry problems such as glue leakage, fabric stretching, finished product wrinkles, and unstable tension, Yonggao Machinery has launched a new tension-free PUR hot melt adhesive laminating machine to help major production companies achieve high-quality, zero-pollution, and high-efficiency lamination production.
PUR hot melt adhesive laminating machine is an environmentally friendly laminating equipment that uses moisture curing reactive polyurethane hot melt adhesive (Polyurethane Reactive) as the bonding medium.
The glue does not contain any solvents, no moisture is added, and the solid content is as high as 100%. It is a solid colloid at room temperature. After being accurately heated and melted by the equipment, it is converted into a liquid glue with strong fluidity and stable viscosity. The equipment can evenly coat the glue on the surface of the base material, and then use a precise lamination process to complete the seamless lamination and compounding of two different base materials. No drying process is required in the entire process, making the production process simpler.
Different from ordinary hot-melt adhesive laminating equipment, Yonggao’s tension-free PUR model focuses on full-process segmented tension-free control, and is equipped with a full set of servo intelligent control systems to completely overcome the stubborn problems in the industry such as stretch fabrics and thin fabrics that are easy to stretch, wrinkle, curl, and compound dimensional deviations, taking into account production accuracy, finished product quality, and production stability.
This product has the following core highlights:
1. Full-range servo drive, the entire machine operates with high accuracy.
The entire equipment is equipped with a full set of servo control systems, and the five core processes of unwinding, cloth feeding, lamination, winding, and gluing are all driven by independent servo drives. Different from traditional variable frequency motor transmission equipment, the operation starts and stops more smoothly and the speed is more synchronized.
The gluing system is equipped with an independent servo metering pump, which can accurately control the amount and speed of glue dispensing, eliminating the problems of fast and slow glue dispensing and uneven thickness of the glue layer, greatly improving the consistency of composite finished products, while reducing glue waste and reducing long-term production consumable costs.
2. Four-stage independent tension-free system, zero stretch of elastic fabric.
This is the core differentiated advantage of this model. The equipment abandons the traditional single tension control mode. For the entire fabric production process, it is equipped with four independent tension detection and adjustment modules for fabric feeding, pre-compositing, composite pressing area, and rewinding to achieve closed-loop tension control of the entire production cycle of the base material.
It is especially suitable for highly elastic knitted fabrics, thin breathable fabrics, elastic mesh and other easily deformable base materials, maintaining zero tension in the fabric during the entire process, and eliminating the problems of stretching, elongation, and loose fabric wrinkles.
All real-time tension data are displayed synchronously and visually on the human-machine PLC touch screen. The parameters are clear at a glance. Operators can real-time monitor and fine-tune tension parameters with one click without complicated debugging. Even novices can quickly get started.
3. Monitor the entire glue application process to completely eliminate the pain points of glue leakage.
In response to production problems such as side glue leakage, incomplete glue application, and glue edge burrs caused by scraper offset and stroke errors that are common in the industry, Yonggao Machinery has re-optimized the gluing structure and upgraded a new closed-loop gluing process.
At the same time, real-time monitoring and automatic calibration of the entire scraper operation are performed to correct the scraper displacement deviation in real time. From the dual dimensions of hardware structure + intelligent monitoring, it completely eliminates the problems of glue leakage, glue overflow, and glue breakage during the production process, making the glue layer uniform and complete, and further improving the composite fastness and the appearance and texture of the finished product.
4. Environmentally friendly moisture curing process, the finished product has better performance.
Adopting the PUR moisture irreversible curing process, the glue can be gradually cured when exposed to air after being bonded. It has high bonding strength and does not require opening of the glue. The finished product has excellent resistance to water washing, dry cleaning, high temperature resistance, and anti-aging properties. At the same time, there is no VOC exhaust gas emission and no odor throughout the process. It fully complies with domestic and European and American environmental protection production standards, and can meet the stringent quality requirements of high-end export orders, maternal and infant products, and personal textiles.
This tension-free PUR hot melt adhesive laminating machine is suitable for a wide range of base materials and is compatible with elastic fabrics, non-woven fabrics, functional films, microfiber leather, various textile fabrics and other materials, covering multi-industry composite production scenarios:
1.
Automobile interior industry: It can fully replace the traditional high-pollution flame composite process, with no open flame, no exhaust gas, and no burning damage to the base material. It is used for composite materials such as automobile ceilings, seat fabrics, door interiors, and sound insulation cotton. The production is safer and environmentally friendly, and the bonding fastness is higher.
2. Functional textiles industry: suitable for waterproof and breathable layer lamination of jackets, elastic pantyhose lamination, sports shoe materials, insoles, and outdoor functional fabrics, retaining the original elasticity and feel of the fabric without destroying the breathable performance of the fabric.
3. Home textiles and maternal and infant products industry: It is suitable for laminating bedding, blackout curtains, terry cloth, and air layer fabrics; it can also process personal maternal and infant products such as adult changing pads and baby care pads. It has no glue odor, is safe and environmentally friendly, and complies with the production standards for maternal and infant products.
Yonggao tension-free PUR hot-melt adhesive laminating machine directly addresses the three core pain points of the industry: out-of-control fabric tension, glue leakage, and environmental failure. With three core configurations: global servo control + four-stage tension-free system + intelligent glue monitoring, it takes into account operational convenience, production stability, and finished product quality. It is the preferred equipment for high-end environmentally friendly composite production lines in the current textile, home textile, and automotive interior industries.
