Hydraulic to Electric Conversions: Saving Time and Money

Work with machinery long enough, and you’ll go beyond just knowing how to use the equipment: you begin to understand it, learn its strengths and weaknesses, and figure out ways to improve it. IIS’s extensive experience with indexing equipment led to one such situation, which we were able to act open to improve our customers’ operations, and our own repair services. In fact, our analysis and upgrade led to a whole new service offering for IIS: the electric drive conversion for the Nissei Hydraulic ASB 650 Blow Molding Indexing Table.

For many years, hydraulic-powered indexing drives were the industry norm. As anyone who has worked extensively with hydraulics knows, the technology offers incredible benefits – with some drawbacks. Hydraulic leaks are messy, hydraulic fluid is expensive, and repairs can be frequent and costly. As a well-established repair shop for hydraulic indexers, IIS noticed something in the course of sourcing replacement parts: they were becoming more and more scarce, and costs were increasing commensurately. The machinery was becoming obsolete. 

Rather than continue to subject our customers to increasing parts costs, we rolled out another option: an electric drive conversion. Time-consuming and a major investment in the short term, the savings in reliability and production over the long term have proved attractive to many clients. The key to the conversion is a special adapter for the gearbox, called the KIT-ADT-43. This is a bolt-in replacement for the original HR-205 type hydraulic motor in the Nissei table. With cycle times reduced to 1.3 seconds for a 90° move in a standard precision assembly, or .99 seconds in a reduced backlash assembly, as well as a substantial reduction in energy usage, the benefits of the conversion speak for themselves. What’s more, our clients are typically eligible for state and federal tax credits for energy efficiency improvement investments.
