Case Study: How Portable Equipment Solved Production Capacity Issues

Posted by Andy Marin on Wed, Apr 03, 2019 @ 01:36 PM

The casting industry is in a transitional period adjusting to new trends and products. Manufacturers require flexibility in their equipment to account for shorter program life cycles while still being able to be competitive. In many instances this requires assets to be spread across multiple programs. It is a landscape that rewards companies who identify opportunities to adapt to the changing circumstances. One example is a case where vacuum impregnation requirements unexpectedly and suddenly increased in one manufacturer's location while another of its locations had underutilized impregnation capacity.

As manufacturing equipment ages, the maintenance and repair (MRO) of the equipment increases while the Overall Equipment Effectiveness (OEE) decreases. Given this, companies must decide while bidding on new projects:  “Use the aged equipment and invest in MRO while accepting a lower OEE” or “Invest in new equipment using the latest technology and generate a higher OEE.”
