Field notes
The process-analysis workflow asks for a part, raw material, and machine, then offers approximate values for settings including speed, pressure limit, V/P changeover, holding, and cooling. The homepage says to compare these with trial-run results rather than treat them as final settings. Its forum displays recent shop-floor questions, while the resource menu also lists a mold trial planner, mold history log, and material reference.
