Laboratory Stretch Blow Moulding Machine for Preform Evaluation

Bench-top stretch blow moulding machine with an infrared heating oven that blows trial bottles from preforms to evaluate processability. Used by preform developers and bottle makers to test new resin grades and preform designs before production.

Specification

Preforms are heated in an adjustable infrared oven, stretched with a rod and blown into a mould at set pressures. Operators study material distribution, stretch ratio and clarity in the finished sample bottle. The machine lets users tune the process without tying up a production line.
