For several years, we have been seeing a boom in rotomolding, thermoforming and blow molding technologies. Different motivations are access to new technical polymers, need to reduce costs and delays, opening up to new more technical applications … Faced with these demands, significant progress has been observed such as improvement of the machines and tools, development of more efficient materials for creating  innovative products … These advances are bases on the industry of the sector, academic studies, which come together to enrich these domains.
