Challenge

One of the main problems in the glass industry is the fast wear and degradation of the surface of molding tools used in the glass manufacturing process, which in direct contact with the melted glass are subjected to severe conditions of abrasion, corrosion and fatigue at high temperatures. The wear occurring in these components (plungers, molds, mouthpieces, etc.) has led, in the last years, to efforts to develop surface engineering solutions to overcome this problem. Having not yet reached the desired success, these solutions would allow reducing the wear, the cracking problems and increase the lifetime of the tools, thus, making the whole process more efficient, by reducing the number of rejected parts and the maintenance time as well as by decreasing the production cycle duration and improving the process from the energetic point of view.

Solution

Taking this into account, pressed by the strong foreign competition, particularly by the leading edge companies where solutions based on surface modification techniques are currently being applied, the consortium aims to develop surface engineering solutions for the protection of the majority of their components, extending the knowledge gained with the plungers to other mould parts; and promote their full or partial implementation in the production line of the promoter company. So this project will be developed on two fronts:
i) Development of internal skills to adapt the manufacturing process of moulds to the application of surface engineering solutions in a HVOF pilot line, to be implemented in the promoter company;
ii) Study and development of surface engineering solutions based on sputtering technology – PVD, for the deposition of thin films with good mechanical properties at high temperature, which could support the harsh conditions of use and increased durability relative to the state of the art. The success of the industrial application of both solutions allows predicting productivity gains and an increase of the competitiveness of the partners companies. The surface modification methods are highly relevant and viable for the protection of mould surfaces used in the production of glass containers.
