The products of aluminium composite panel manufacturers generally have a gap of a certain width between the panels,
which are generally filled with a black sealant for aesthetic reasons.
And what problems can arise when making the conformation? One problem is the quality of the coating,
which mainly occurs during the pre-treatment and painting and baking process of the aluminium panels.
Another is the quality of the compound, mainly technical problems and management problems in the compounding process.
Some of these problems are affected by a single factor, some are the impact of a variety of factors.
In fact, the quality problems in the composite process of aluminium composite panels are mainly plate surface bulging,
plate surface trapped spots, ruffled edges and poor bonding, which should be analysed and discussed separately.
When aluminium composite panels are cut, the protective film can produce different degrees of tearing,
so it is impossible to pack the glue seam neatly when using it as a substitute for protective tape, and this needs to be understood.
