Leading manufacturers are seeing the value that customised foam trays bring to their operations. Component identification and security has been increased. Machined parts can be placed into its carefully created space in the foam that can avoid damage especially to intricate and delicate items.
Moving items around becomes less hazardous and costly. Easy to keep clean and sanitised, closed cell foam has qualities that other options do not offer.
Not just internally but between manufacturers, who provide different stages of the process, no matter where in the world they are. It reduces the need for different packaging for each stage and makes a big social and environmental statement.
