$EVs Are Starting to Kill the Auto Parts Industry Internal combustion engine valves, or poppet valves, are conceptually simple components that have been around for well over a century. Producing them in mass quantities is done with special-purpose machine tools and interesting friction welding technology to meet stem with head. But as internal combustion engine demand is predicted to flatline and eventually fall with the advance of electric vehicles, the science and art of valve making would appear to be on the way out. A recent auction of the assets of a technical valve making facility in Germany chose special-purpose machine tools for valve making on the block at prices a tiny fraction of what they cost new. Valves may be on the way out, but more significantly, the concept of highly specialized, single-purpose machine tools for mass production is on the block as well. *ABOUT END OF THE LINE:* Manufacturing veteran James Anderton expresses his compelling and unique opinions about the state of the manufacturing sector and the engineering industry more broadly. He shares his thoughts and insights to help engineering and manufacturing professionals navigate through the challenges of world events, the blending old with new technologies, evolving processes, gaps in skilled labour, in an effort to help maximize productivity of their daily operations. Occasionally, he just likes to vent. James is a former editor of trade publications in the automotive, metalworking and plastics industries with contributions to a wide range of print and on-line publications. He also brings prior industry experience in quality and manufacturing for a Tier One automotive supplier. * * * *JOIN ENGINEERING.COM:* Easy, free.
