Due to our method of operation, as well as producing the mould as a single-piece unit, its wall is also thicker than the wall present in the moulds made by our competitors. This makes our mould more robust, which gives it a longer useful lifespan.
One of the components of the plastic raw material is ethylene, which gives it elasticity. Over time this tends to evaporate crystallising the molecules of the plastic.
For this reason, if the mould has a thicker wall this will prevent the early loss of elasticity and the consequent breakages arising from the deterioration of the plastic, more common in the areas where welds or joints are present.
