It is indeed injection molded, I was able to locate a mark on the bottom of the casing, I forgot the term, it may be ejector pin or something else, but it's obvious.
I sent the casing to a plastic supplier in my area to find out what it's made of. I was able to do some lighter tests, if I leave the flame on for 5 or so seconds it will ignite, and it turns an ugly greyish/black once ignited. The only solvent I have laying around is Acetone which greatly affected the items, made them develop a white texture which I am not able to remove.
Our ultimate goal is to reproduce these items, and I've been looking into some CAD designers who I could send the product to, although they will need to touch the 3D scan up because the cases we have now are a little damaged from being pryed apart, which are they not designed to do (like you see in the photo).
If I can't find someone for that service, I will likely get some high quality scans and try sending them to someone on fiverr to develop the 3D files. Our budget for these service/s is very large, in case anyone is interested in assisting me. Thank you for the responses
