I don’t know how many of their hvac and pollution control systems are made in-house. Probably outsourced. But im sure they have tool and die guys to make injection molding tooling for plastic and rubber components.
And FEA and design and manufacturing engineers to design the volumetric flow pumps, circuits and valves....
Hopefully they could just manufacture under a liscence agreement and just create their own independent tooling. But Im sure the cleanliness and quality/compliance engineering would be the biggest ‘ob stac al’.
1. I doubt GM is in the plastic injection molding processes. That would be a Tier 1 supplier, not done in-house so to speak.
2. It takes months to build a plastic injection mold. That could be shortened, yes. But the supply chains for key materials are shaky right now. Better move on this yesterday.
I used to work in sales in a related area of manufacturing -- metal stamping -- and as such I was in/out of a lot of tool & die shops. A few of those built molds as well as stamping dies. Dirty little secret: Most of those shops I called on are long gone.
