As a Gypsum Board Production Line Supplier, laminators are especially important in gypsum board machinery. Once the machine has problems in production, it will directly affect cost control and product quality. There are several possibilities for the deviation when the film is applied:
First, the problem of flattening the roller.
In order to ensure the film quality of some deep grain pvc film, the general filming opportunity uses multiple flattening rolls. However, if improperly adjusted, the flattening rolls will be non-parallel to each other, causing deviations in the unfolding of the PVC film, which may lead to deviation during filming. In this case, it is necessary to adjust the flattening roller to achieve the most ideal standard. This situation is rarely seen after the installer has completed the commissioning, but the adjustments need to be careful.
Second, the pvc film itself.
In order to reduce costs, some manufacturers have chosen a cheaper pvc film. This pvc film is prone to chromatic aberration and is generally overstretched. This causes the pvc film itself to be uneven, and it is difficult to use even if the flattening roller is adjusted. This will not only lead to deviations in the filming, but also wrinkles and bubbles. The problem of the material itself is generally difficult to solve. In order to ensure the quality of the product, it is recommended to use a qualified pvc film.
