The next step is therefore cooking the shells in an oven at 1000 ° C, which will ensure their resistance.
Then comes the casting of the molten metal (we clearly see the carapaces 'blush' during the descent of molten metal).
The clusters of forks thus obtained will pass after cooling to stall and shot blasting, in order to eliminate the shells by vibration.
Finally, the bunches will be cut to collect the small forks, then the attacks of castings (also called weights) will be ground before the very last step: the finish.
