Chip Ganassi Racing workers measure all the metal they use in car fabrication, from the chassis to suspension component.
In a previous article, we discussed how new steel grades are driving positive material identification (PMI) programs in automotive manufacturing. Off-specification metals will fail to perform as expected and can have dangerous, even catastrophic consequences. So, Positive Material Identification (PMI) — the practice of testing materials for their exact chemical composition to ensure that the incoming raw materials and the outgoing finished parts meet engineering requirements — is an integral part of the automotive world.
Employees at Chip Ganassi Racing, makers of Nascar racing cars, take this practice to heart. They never take for granted that the materials they order are the materials that they receive, even if the shipment comes with certification papers. Ganassi measures all the metal they use in car fabrication, from the chassis to suspension components, to make sure they are up to design specs.
