The requirement to convey materials efficiently, safely and as rapidly as possible is vital for a successful injection moulding operation. Machinery manufacturers are designing cost-effective and versatile materials handling systems to meet the need for flexibility in the moulding shop, and ancillary suppliers are ensuring that materials delivered to the injection moulding machine are in the required form and the correct amount.
INJECTION WORLD | October 2017 The latest innovation from US-based Conair is
the Wave Conveying vacuum material-handling system. The company says that it is based on vacuum conveying technology developed to move pellets at speeds of 1.5 m/sec and eliminate pellet damage and friction-related problems, such as angel hair associated with conventional high-speed conveying. For the hardest, most abrasive glass- and mineral-filled materials, research showed that these slow material speeds gave the best results. However, after two years of further research, it was found that a much wider range in speeds from 5-14 m/sec was possible for many materials. At these speeds, there is a gradual transition from dense- phase to a more dilute phase, and in this transi- tional phase, a true wave forms as material rolls over on itself. This wave conveying still prevents heat build-up and resin damage while significantly increasing throughput rates compared to other types of conveying. Conveying distances can be
