The application of metal shoe accessories with automatic drilling machines was already known. But that the same application could be realised with plastic eyelets and grommets seemed impossible until now. Yet, thanks to the ability to invent, the mastery of materials and the development of technology, someone finally succeeded. And that someone could only be us, who have innovation inscribed in our DNA.
Why couldn’t composite eyelets and grommets be applied with self-drilling machines until now? The answer is simple: because there was no suitable plastic material that could withstand the processing temperatures and offer total reliability. The material itself is one of Grinn’s secrets: ductile and amorphous, it is cold-formed and retains its characteristics.
The greatest advantage of this new technology is that it benefits the environment: firstly, a saving of more than 20 per cent in plastic material and consequently less processing energy, which in turn results in significantly reduced emissions. Grinn testifies to our ever more concrete commitment.
This new approach facilitates the machining processes of the technical components on the footwear from a production point of view by guaranteeing fast assembly, cost savings, and machining precision. Application is also simplified to the nth degree thanks to the elimination of an element. If we add to this the exclusive advantages of the composite material (lightness, design, colour) we obtain a product line destined to change the international footwear panorama.
But the material is not enough: once made, it remains to devise and implement a technology that can make the most of it. Here, too, we were able to draw on our experience in the development of innovative production processes, particularly for the processing of plastics.
