All hydraulic injection molding machine will benefit from a retrofit system installed to regulate motor speeds and save energy; it's probably the most important energy-saving investment a molder can make. Many USA molders harbor great cost reduction potential, with very attractive rebate programs to make such energy saving projects not just a desirable goal but a business necessity. What you need to know is how much energy saving can be expected, what will be the costs, which systems work well & reliably, and which ones do not.
This presentation covers all the issues from an experienced world leader in the design and retrofit of frequency inverter (variable speed drive) systems for energy savings on injection molding machines, based in USA and headquarters in UK.
