How to Reduce Injection Molding Costs Without Sacrificing Quality & Reliability

Adrian and Paul break down why molding costs “balloon” (over-tight tolerances and cosmetic overkill) and then walk through three practical levers to cut costs safely: smarter tooling design & DFM (wall thickness, draft, gates, material choice), good tooling decisions (steel grades like P20 vs H13, cavity count, hot vs cold runners), and production/process tweaks (machine tonnage matching, sensible regrind use, SPC/sensors, in-tool de-gating). They finish with some tooling-costs myth-busting (cheap tools, mirror finishes, family molds).   Episode Sections: 00:00 Intro & today’s topic 01:58 Why costs balloon: tolerances & cosmetics  06:52 Lever #1 — Design & DFM (wall thicknesses, material choice)  14:40 Lever #2 — Tooling decisions (steel grades, cavities)  22:44 Lever #3 — Processing & production setup  27:35 Myth-busting: cheap tools, mirror finishes, family molds  31:23 Recap & where the biggest savings really are   Related content...
