I recently found the following link https://anglingai.com/224b-4-4-blood-line-swim-bait-mold/. There you will see that they sale hundreds of different aluminum molds related to fishing. These molds are really inexpensive (from 50 up to 200 USD). How they are producing them? I though that molds cost thousands of dollars.
I am currently in progress on designing a product and I will need a mold for the enclosure of the product for low production runs (no more than 200-300 items per month). The enclosure will need to be either from ABS or some other kind of strong material that is not brittle. Probably also, the material will need to somehow be manually injected in order to reduce the total cost.
Where can I find someone to produce me low cost molds (like the above) for a product design that I will create with Fusion 360? Can this be done or I am really naive? I am mostly interested for the outside finish of the enclosure. Inside it there will be electronics that will be potted with special type of resin in order to protect them from the elements. As such, the inside will be as simple as possible.
