The gear additionally allows environment friendly manufacturing planning and reduces warehouse house. The SBO 16 EvoBLOW produces a 2 L format whereas the SBO 10 EvoBLOW produces all bottle codecs as much as 1 L. Because the latter manages varied bottle codecs, the corporate additionally selected to put in a mould Bottle Change system to conduct ultrarapid bottle changeovers. “This straightforward technique to adapt our oil manufacturing to the fast-moving market calls for contribute to a fantastic manufacturing flexibility.”
 
This technique is predicated on repeatable, tool-free operations that imply the operator spends solely 30 seconds per cavity, thereby rising manufacturing flexibility, gear availability and manufacturing uptime. Each machines can function at an effectivity degree of 99.5 per cent whatever the Finish-of-Line efficiency, due to the manufacturing buffer created by the storage silos situated on the traces. “With these two blowers, we already elevated our yearly manufacturing quantity by 50 per cent and we’re able to deal with any future extra demand as nicely,” added Modi.
