#356 - CEP vs Moldagem Científica: Qual é o melhor controle de processo na injeção de plásticos?

In this video, we explore one of the most interesting discussions in process engineering for plastic injection molding: SPC (Statistical Process Control) vs. Scientific Molding. You'll understand what SPC/CEP is, how Cp and Cpk work, the concept of process stability, and how scientific molding uses process physics to control filling, compaction, and gate freezing. We also discuss the advantages, limitations, and criticisms of each approach, including the debate about monitoring historical data versus controlling fundamental process variables. Finally, we show why SPC and scientific molding don't need to compete—they can complement each other to create more robust, stable, and predictable injection molding processes.
