Going on with our innovations we are going to introduce the polypropylene strap mold. The advantages that this kind of material is that we can machine it very fast. So we can make customize mold strap because we use cast polyurethane for strap. Polyurethane has better propierties than natural rubber for strap watches. Moreover is a advanced material is a lot of thing like sport shoes.
Polyurethane is not injected, it just filled in the mold and it is closed with some screws. We put the mold in a oven to 90º for some hours in order to cure the material easier. When the part is finished the edges are deburred the and polished it.
This strap can be made in different colors ans sizes because the customization allows it.
