Molds

The mold is done from the master, it is the negative of the master. This mold once it will be finished will be used to inject the wax that will be used for the casting.

Differents materials that exist to make this mold but there is two big families:

The silicons

This materials provide a better definition but the lifespan is short.

The rubbers

These materials have a long lifespan but the definition is less

Depending on the need we have to choose the best to use. for example with the new semi automated wax injecting system all the rubbers cannot be used and it is even better to use silicon

Here is the different step to make a mold :


First covering the master with the rubber


Vulcanize the rubber


Cutting the rubber
