If you are familiar with GM and the buying strategies they have used in the past, then this is not a surprise. The automaker is looking to have a list of pre-approved resins – worldwide at that – from which they will allow their parts to be made.
From the company’s perspective, they claim they will gain many advantages:
Here’s my thoughts on these three ideas:
Having worked in a large corporation that also tried to cut down on the number of raw materials it was using, I predict that the list will quickly fail. Some designer will need a resin, and find that some resin not on the list will work and will work at a lower cost than some resin on the list. While the approved resin will initially be used, a period of cost-cutting will quickly follow and the alternate resin will get added to the list. And so the list will grow.
At the end of the day, the only thing left from the wish list above will be the somewhat improved purchasing power of GM, something that they have been known for for decades. Bankruptcy has not changed their modus operandi.
