Feasibility study
Find the right polymer or blend (shelf life, chemical properties, thermal properties, etc)
Evaluation of the right technology: 1 stage ISBM, IBM or EBM or 2 stage IM+SBM
Technical feasibility ( technology, cycle time, stretch ratio, neck Ø , preform design e.g.)
Breakdown activities
Gannt
Cost evaluation for a pilot phase ( materials, moulds, processes)
Cost evaluation for a industrial phase (investment, cycle time, efficiency, people, packaging, transport cost)
