TECHNOLOGY ASSESSMENT OF TIRE MOULD CLEANING SYSTEMS AND QUALITY FINISHING
Authors: Cristiano Fragassa, Martin Ippoliti
Abstract: A modern tire merges up to 300 different chemical elements, both organic and inorganic, natural and synthetic. During manufacturing, various processes are present such as mixing, calendering and extrusion, forming dozens of individual parts. Then, moulding and vulcanization inside special moulds provides the tire its final shape. Since the surface quality of moulds strongly affects the quality of tire, mould cleaning is a fundamental aspect of the whole tire production and cleaning techniques are in continuous development. This investigation proposes a global technology assessment of tire mould cleaning systems including uncommon solutions as multi-axis robots for cleaning on board by laser or dry ice, or ultrasonic cleaning which use cavitation. A specific attention is also focused on the industry adoption of spring-vents in moulds and how they are influencing the development the quality of final products.
