ABSTRACT:
A process for the manufacture of an orifice plate for pelletizing of plastics in which inserts are inserted into corresponding recesses in the orifice plate, the inserts being formed with blind bores before their insertion into the recesses. The blind bores terminate in proximity to the outer surface of the inserts and after soldering of the inserts into the recesses and hardening of the inserts, the outer surface of the base plate and of the inserts are ground down to expose the blind bores and form a planar outer surface for the orifice plate.
