Abstract

The present disclosure provides methods and apparatuses providing uniform polyamide pellets. In one example, a method can include maintaining a vacuum during a pre-casting polymerization cycle of the cyclic process such that the pre-casting polymerization cycle produces a reactive polyamide polymer with decreased pre-casting polymerization cycle time, extruding the reactive polyamide polymer during a casting cycle by adjusting process parameters including vessel pressure and extrusion valve opening to generate a throughput of extruded polymer, and cutting the extruded polymer at a cutting speed substantially proportional to the throughput to provide polyamide pellets.
