Therefore, while using traditional welding processes (heated bars, impulse, ultrasound), millions of packages must be produced to make production profitable . But if we want to be more original, how can we do it?
The first step would be to produce prototypes to validate the desired shape, before embarking on the manufacture of specific tools.
Sealester offers THE solution: an innovative welding process, which is based on a digital welding technique to produce personalized flexible packaging, in mini and small series, without any additional tooling costs.
What does it consist of? It is a mobile welding tool, which follows a trajectory determined by the operator, applying pressure on the films to be welded.
Changing the shape of the weld consists only of changing the tool trajectory program.
This technology is integrated on an independent machine whose main objective is to produce prototypes, allowing packaging designers and users to validate concepts before launching series production.
But how to adjust the settings?
For adjusting the welding parameters, this process is linked to a digital algorithm which determines the values of the process parameters allowing a good weld to be obtained. Adjustment times are then optimized: they no longer depend on the know-how and experience of the operator, but on the result of an instantaneous scientific calculation.
What about new eco-responsible films?
New eco-responsible films (mono-material and/or recyclable and compostable films), just like traditional films (complex polymer films), can be welded with DigiShape.
