2-Step ISBM Optimization
Like Duolingo, but for 2-Step ISBM Optimization. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
A short one: 9 levels across 2 sections, about 18 minutes end to end, roughly 4 days at five minutes a day. It moves through Thermal Control and Preform Dynamics and The Blow Cycle and Morphology.

Key ideas in 2-Step ISBM Optimization
- Higher hoop ratios increase lamellar orientation, significantly improving CO2 barrier properties
- Spherulitic crystallinity at the gate creates brittle points that act as stress concentrators during the blowing phase
- Excessive expansion beyond the resin's strain-hardening point leads to 'pearl' (micro-voiding) and reduced structural clarity
- Optimal gate quality requires an amorphous state to allow the material to flow and thin correctly into the bottle's base petals
- Predicting the impact of expansion ratios on container performance
- The relationship between expansion ratio and local cooling rates determines the final crystallinity of the container wall
- Thermal stress cracking in ISBM bases is frequently traced back to poor gate cooling during the initial injection step
- Evaluating the relationship between preform gate crystallinity and base failure
- Neck finish must remain below Tg
- NDR and strain hardening
- Heat soak causes ovalization
- Expansion ratios and barrier properties
- Softening leads to telescoping
- Exceeding NDR causes over-stretching
- Higher NDR requires lower stretch ratio
- Preform gate crystallinity
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives 2-Step ISBM Optimization the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
When designing a bottle for carbonated drinks, why might you choose a higher hoop expansion ratio?
