The electrification of automobiles has had a knock-on effect for machinery manufacturers, one OEM representative told us at NPE 2024: Acceptance for all-electric processing equipment is growing.
More than a decade ago, in a blog post, Paulson Training, Chester, Conn., already was taking notice of the transition: “Electric injection molding machines have quickly become a normal sight in many injection molding plants. After a somewhat slow start, the advantages of all-electric molding machines have accelerated their implementation. The reasons for the growing popularity of all-electrics are many. Among the most important reasons are consistency, repeatability, and accuracy.”
While machinery makers at NPE2024 showed off all-electric IMMs and blow molding machines, OEM representatives say for many plastics parts makers, the best choice might be a best-of-everything approach: hybrids.
By a large margin, molders running machines with under 500 tons of clamping force prefer all-electrics, said Ben Hartigan, marketing coordinator for the Absolute Group of Companies, which in North America sells Haitian IMMs as well as a line of robots.
But at greater tonnages, the benefits are less apparent.
It comes down to a question of preference.
“Our advice to choose all-electric or servo-hydraulic would completely depend on the application the machine will be used for, and we advise our customer to take a serious and close look before making a decision based on market trend or feeling,” said Marko Koorneef, president of Boy Machines.
