Parison Stretching: PSM 500-SD
Parison stretching is integral to the balloon blowing process, and Medical Production Technology Europe BV has applied its innovative design expertise to develop the PSM-500-SD parison stretching machine. Designed to be used in conjunction with the MPT BFM-500-S2 and BFMS-500-S2 Balloon Forming Machines, the PSM-500-SD utilizes split die technology to deliver optimal stretching results while addressing the limitations of currently available machines.
Fully servo-controlled, the PSM-500-SD stretches parisons with forces up to 500 N. A precise, easy-to-use sensor system enables well-defined secondary stretch for consistent, repeatable parisons, with recipe-based control managing all parameters.
An innovative pre-heating system prevents the stretching dies from damaging the parison material before or during stretching, preventing die pollution and eliminating associated production downtime and rejected products.
Stretching dies can be easily removed and replaced with dies of different dimensions, and we can quickly produce highly polished custom dies to meet specific dimensional requirements.
Built to the high-quality standards and design philosophy of Medical Production Technology Europe BV, the PSM-500-SD is a reliable, precise solution for demanding parison-forming applications.
