| Converting Machined Parts to Die Casting | |
| When production runs for a machined component part increase, advanced net-shape die casting can offer substantial unit cost savings compared to part machining to specifications. Such cost reductions are being achieved for a wide variety of machined part applications in a range of alloys and part sizes. In the case of many small precision parts, the net-shape 4-slide miniature die casting process can be used to replace a brass machined part at no sacrifice in mechanical properties for significant savings at even low production volumes. This Tech Brief discusses the many advantages of machining-to-die casting conversions in addition to unit cost savings. ConvMchtoDCtb.PDF |  |

In the production of non-ferrous metal castings, die casting is the most energy-efficient casting process, with reusable molds and very high production rates resulting in highly-efficient energy usage. The carbon footprint of the die casting industry is among the lowest among producers of net- or near-net shape products and component parts—far less than that of plastic injection moldings.

In the production of non-ferrous metal castings, die casting is the most energy-efficient casting process, with reusable molds and very high production rates resulting in highly-efficient energy usage. The carbon footprint of the die casting industry is among the lowest among producers of net- or near-net shape products and component parts—far less than that of plastic injection moldings.

| The Insourcing Boom: Updated, In-depth look at the Comeback of Manufacturing to the U.S | |
| Charles Fishman, award-winning investigative and magazine journalist writing in the Atlantic magazine, explores what he calls a startling, sustainable, just-getting-started return of industry to the United States. After years of offshore production, U.S. companies are moving much of their far-flung manufacturing operations back home. General Electric is an early example, but it is not alone. Whirlpool, from China to Ohio; Otis, from Mexico to South Carolina; even Wham-O, from China to California. This Tech Brief is a condensation of his recent in-depth article with reasons for these major production shifts that he labels “The Insourcing Boom.” InsrcBoomTB.PDF | |
| USA Today: Manufacturing Heading Back to USA? | |
| August 2010 article reports on plans for important production moving back from far-flung locations such as China; 400 jobs in the case of GE, 2000 jobs for components provided by suppliers for Ford. For the complete story and the reasons reported for this "reshoring" movement, MfgBck2USTB.PDF | |
| Rising Wages, Acknowledgment of Hidden Costs Bring Manufacturing Back to U.S. Shores | |
| There is a resurgence of manufacturing in the United States as the allure of offshore sourcing begins to fade.
Several studies released this year by major consulting firms, and articles in a variety of publications have noted the rise in U. S. production. Examples range from Fortune 500 giant Caterpillar Inc. to toy manufacturer Wham-O
Inc., which are either expanding operations here, or
bringing back production from offshore suppliers. Die casters are seeing a similar trend, with nearly a quarter of NADCA members reporting they gained new business that had previously been sourced offshore. NADCAHidCstsOffShr.pdf |  |
