Process & QC — Gate Seal Study Planner
Gate Seal Study Planner for injection molding process control.
The gate-seal study is molding's cheapest experiment: step hold time up, weigh parts, find the plateau. Holding past seal wastes cycle; cutting before it un-packs the part as the gate drools backward. Ten minutes of weighing sets the hold time for the tool's life.
Formula
Note: Starting-point process values — the resin grade's datasheet and an in-mold study govern. Verify with a gate-seal study and a cooling-time ladder on the actual tool.
Gate Seal Study Planner for injection molding process control. A free injection molding cycle & process tool — no sign-up, no upload, instant results in your browser.
About Process & QC — Gate Seal Study Planner
Process & QC — Gate Seal Study Planner computes the governing relationship increase hold until part weight stops rising — that's gate seal live as you type. The gate-seal study is molding's cheapest experiment: step hold time up, weigh parts, find the plateau. Holding past seal wastes cycle; cutting before it un-packs the part as the gate drools backward. Ten minutes of weighing sets the hold time for the tool's life. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
