Temperature is one of the most important process variables in the stretch blow moulding process, yet current measurement techniques are limiting opportunities to further control, optimise and improve processing.
BMT’s patented THERMOscan technology allows the simultaneous measurement of the internal and external preform temperature profile, providing the user with the data they need to make informed decisions.
Insight into the mould is paramount for a true understanding on how various parameters affect the blowing phenomenon.
BMT has created an intelligent rod that contains a pressure sensor – for measuring the air pressure development right in the expanding preform, and a load cell – located at the tip of the stretch-rod to accurately measure the stretching force.
The intelligent data-rod allows the mapping of a ‘process fingerprint’ that, along with the rod displacement, offers an unmatched record of the in mould preform development into the fully formed bottle.
