Cycle Build-Up — PET Preform (48-cavity)
Full cycle assembly for a pet preform (48-cavity): fill, pack, cool, open/eject, with hourly output.
Preform systems pull the part at ~70 °C into post-mold cooling tubes — stealing 60% of the 'cooling' out of the press. The in-mold time here assumes that robot; without it, double the cool phase.
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 Cycle Build-Up — PET Preform (48-cavity)
Cycle Build-Up — PET Preform (48-cavity) computes the governing relationship cycle = fill + pack + cool + open/eject; output = 3600/cycle × cavities × uptime live as you type. Preform systems pull the part at ~70 °C into post-mold cooling tubes — stealing 60% of the 'cooling' out of the press. The in-mold time here assumes that robot; without it, double the cool phase. 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 Cycle Build-Up — PET Preform (48-cavity)
- 1Enter your values — Fill time, Pack/hold time, Cooling (after gate seal), Open + eject + close and more (sensible defaults are pre-filled).
- 2Read the live results: Total cycle, Parts per hour, Per 24 h.
- 3Check the "with your numbers" line to see cycle = fill + pack + cool + open/eject; output = 3600/cycle × cavities × uptime substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
