Today, let's talk about a fundamental piece for the project, without it would not be possible to manufacture our rivets: mold.
The mold is where molten metal is poured. Depending on the type of casting we could have various kinds of molds. They can be divided into two major groups: the permanent ones and the lost ones. Lost molds are usually made of sand, as the permanent ones are usually made of metallic materials, they can vary according to need.
In the case of our team we have used a permanent cast steel in 1020 which was machined to have the characteristics necessary for our foundry to be as accurate as possible. A metallic permanent mold was used because of convenience, but presented some difficulties in machinability.
