Advantages
Compared with the single station solventless laminating machine, the double station type mainly has the following advantages.
1. High efficiency. Normally, the stable working speed of the solventless laminating machine is 300 ~ 600 m / min, which is about 2 to 3 times higher than the dry laminating machine. The double-station solventless laminator can greatly reduce the time of roll changing and downtime, improving production efficiency, with generally 70% higher yield.
2. Significantly reducing operational difficulties. Single station solventless laminating machine requires frequent replacement rolls, one unwinding or rewinding unit is replaced once every 15 to 30 minutes, which greatly consumes the operator’s physical strength. The physical strength of the personnel will be accompanied by a certain degree of tension, which will inevitably affect the progress and product quality. The roll changing without the downtime of a double station solventless lamination machine can avoid this.
3. Improve production stability. The double-station solventless lamination machine greatly reduces downtime, improving tension control and adhesive viscosity consistency, which will improve production stability.
Disadvantages
However, there are some potential disadvantages for double station solventless lamination machine, because the material feeding is long with higher tension control requirements and the waste rate will also increase accordingly, and there may be unfavorable effect for solventless composite products with lower initial adhesion. In addition, the cost of a double-station solventless lamination machine is also significantly higher than the single station type.
