Abstract in another language

Bottles made of plastics are used in a variety of applications. In high-volume applications, e.g. medium sized
water bottles made of polyethylene terephthalate (PET), a two-step stretch blow moulding process has been
tremendously successful for realizing top quality, flexible and rigid packaging’s.
One-step stretch blow moulding is much more applicable for small sized bottles in small-volume applications.
FEA using SIMULIA Abaqus has been successfully applied to reproduce and investigate the process steps
starting from injection moulding, succeeded with thermal conditioning and finishing with stretch blowing
inside a one-step production equipment. These FEA approach is qualified to reduce time-to-market by
replacing the traditional try and error procedure. The simulation based process design is the starting point
also to produce bottles with as few material as possible using energy efficient process configurations.
