Cooling Time — Polycarbonate (PC)
Theoretical cooling time for a Polycarbonate (PC) part from wall thickness and temperatures (Wübken plate model).
PC demands heat everywhere — 300 °C melt, 90 °C mold — and punishes wet pellets with hydrolysis that permanently cuts molecular weight, not just cosmetic splay. Cooling scales with thickness SQUARED — the 0.5 mm a designer adds 'for strength' costs every cycle forever.
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.

About Cooling Time — Polycarbonate (PC)
Cooling Time — Polycarbonate (PC) computes the governing relationship t = h²/(π²α) · ln[(4/π)·(T_melt−T_mold)/(T_eject−T_mold)] live as you type. PC demands heat everywhere — 300 °C melt, 90 °C mold — and punishes wet pellets with hydrolysis that permanently cuts molecular weight, not just cosmetic splay. Cooling scales with thickness SQUARED — the 0.5 mm a designer adds 'for strength' costs every cycle forever. 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.
How to use Cooling Time — Polycarbonate (PC)
- 1Enter your values — Max wall thickness, Melt temperature, Mold (coolant) temperature, Ejection temperature and more (sensible defaults are pre-filled).
- 2Read the live results: Cooling time, Share of a typical cycle.
- 3Check the "with your numbers" line to see t = h²/(π²α) · ln[(4/π)·(T_melt−T_mold)/(T_eject−T_mold)] substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Cooling Time — Polycarbonate (PC)?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula t = h²/(π²α) · ln[(4/π)·(T_melt−T_mold)/(T_eject−T_mold)] with authoritative sources cited on the page (Osswald & Hernández-Ortiz, Polymer Processing — Modeling and Simulation; Resin supplier processing data sheets (per-grade values govern))
- ✓PC demands heat everywhere — 300 °C melt, 90 °C mold — and punishes wet pellets with hydrolysis that permanently cuts molecular weight, not just cosmetic splay.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the cooling time — polycarbonate (pc) use?+
It evaluates t = h²/(π²α) · ln[(4/π)·(T_melt−T_mold)/(T_eject−T_mold)], exactly as published. Sources: Osswald & Hernández-Ortiz, Polymer Processing — Modeling and Simulation; Resin supplier processing data sheets (per-grade values govern). The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
PC demands heat everywhere — 300 °C melt, 90 °C mold — and punishes wet pellets with hydrolysis that permanently cuts molecular weight, not just cosmetic splay. 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.
When is this calculator the right tool for the job?+
Theoretical cooling time for a Polycarbonate (PC) part from wall thickness and temperatures (Wübken plate model). A free injection molding cycle & process tool. Cooling scales with thickness SQUARED — the 0.5 mm a designer adds 'for strength' costs every cycle forever. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
