​SpaceX to Build Starship Rocket out of 3XX Stainless Steel, Not Carbon Fiber

By |2019-01-24T20:28:04-04:00Jan 26, 2019|Blog|0 Comments

​Stainless steel will be used for the SpaceX Starship and Super Heavy rocket booster. Over the spectrum of operating temperatures and ​conditions encountered, stainless steel has better performance than carbon fiber. ​From a recent interview with @PopMech, it's apparent that @ElonMusk has more than just a passing awareness of materials and manufacturing. In it, Musk describes how material selection affects stiffness, fracture toughness, and of course cost. He talks about [...]

Efficiency at What Cost?

By |2019-01-14T21:10:20-04:00Jan 18, 2019|Blog|0 Comments

Electric motor efficiency is improved by using thinner sheets of electrical steels. This is important to meet the needs of hybrid/electric vehicles. But more laminations need to be stamped from this thinner metal to get to the same stator height. An article from steelmaker voestalpine says that at least 60 additional high-precision stamping lines/presses will be needed by 2025 for production of 25 million drive motors with a lamination thickness [...]

POSCO will invest US$40 billion and hire 20,000 by 2023

By |2019-01-10T22:53:01-04:00Jan 14, 2019|Blog|0 Comments

​More than half will go to automating a 3.52 million ton Gwangyang Steel Mill blast furnace, expanding production capability of their "Giga Steel" and establishing power generation facilities using byproduct gases. Other funds will be devoted to secondary battery materials and upgrading lithium-extracting technologies, with a similar amount going to their energy and infrastructure businesses. Read more about Posco's plan. -Danny Schaeffler, www.EQSgroup.com and www.Learning4M.com ​

Metalforming Magazine’s Top 10 Articles on Servo Press Technology

By |2019-01-10T22:28:33-04:00Jan 11, 2019|Blog|0 Comments

Metal Forming Magazine assembled a collection of articles discussing servo press selection and usage. These articles will take you through the justification process by highlighting their benefits and what these presses offer above and beyond flywheel-driven presses. In addition to the potential for increased throughput, optimizing forming velocity during the press stroke helps reduce heat build-up, lube burn-off, and minimize die wear. Read more about servo presses at MetalForming Magazine. -Danny [...]

Forming Advanced High Strength Steels? Elongation May Not Be The Best Indicator

By |2019-01-02T20:33:27-04:00Jan 3, 2019|Blog|0 Comments

SSAB has a good post on why tensile test elongation is not the best way to assess formability of AHSS steel.  It has to do with averaging deformation over a large gauge length. Coincidentally, I've written about this in an article to be published in the February 2019 issue of MetalForming Magazine. Read more from SSAB in their article, The Forming Myth -Danny Schaeffler, www.EQSgroup.com and www.Learning4M.com  ​

​Excited to report that Bill Frahm of 4M Partners made it on to the “Top 5 in 365” list of the five most-popular stamping related articles on www.thefabricator.com! In the article, Statistics and Probability for Better Decisions in Manufacturing, Bill writes: "If you manage the manufacture of high-volume products, you also generate large volumes of data. Buried in that data are pieces of information that can direct you to make [...]

Sensors and Industry 4.0 Come to Sheet Metal Forming

By |2018-12-08T15:48:33-04:00Dec 8, 2018|Blog|0 Comments

Nice article about the use of sensors in stamping and relation to Industry 4.0.  If you don't think you can justify sensors, my recommendation is to track coil-by-coil performance [bad AND good] to see effect of metal props. You might find that success is a function of more than just YTE or hardness. Sensors like tonnage monitors will help focus corrective actions. https://www.thefabricator.com/article/stamping/r-d-update-industry-4-0-and-the-use-of-sensors-in-sheet-metal-forming -Danny Schaeffler, https://www.EQSgroup.com and https://www.Learning4M.com  ​

​​Abhay (Abe) Vadhavkar of CAR writes about the impact of sourcing tools overseas on the US tool & die sector.​  The report​​ ​states that new tooling sourced in Low Cost Countries such as China and Taiwan may cost 20 percent lower than US sourced tooling, with similar time-to-completion, even with shipping. ​ Among other things, the report highlights ​the​ advanced age of US tool & die workers and potential for US-based shops to become [...]

The Aluminum-Steel Battle in Automotive Applications

By |2018-11-11T12:43:55-04:00Nov 30, 2018|Blog|0 Comments

Steel and aluminum alloys are looking to be the chosen metal in auto bodies. Why? There are 2 tons of sheetmetal purchased for 17MM vehicles sold each year in the US - there is no other industry with such high-volume sales opportunities. Read about strength, stiffness, and joining in my article in the May 2018 issue of MetalForming Magazine at www.metalformingmagazine.com/magazine/article/?/2018/5/1/The_Aluminum-Steel_Battle_in_Automotive_Applications
