BFMS-500-S2 Split Mold Balloon Forming Machine

The Split Mold Balloon Forming Machine (BFMS-500-S2) is the third machine in a range of balloon forming machines that has been developed by MPT Europe BV.

It has full servo control on the proximal and distal axis. This allows for precise and fast stretching of the parisons during the balloon blowing process. The axis have force control and individual load cell systems allowing forces to be monitored and used as control parameters during the process.


The split mold die allows for complex designs and can be quickly replaced. The high closing force and perfect alignment make the system reliable and stable in use. The machine can be fitted with the MPTEurope BV developed Acitve Pressure Drop Control(option) that provides a significant control handle to the blowing process and allows for more optimization of your balloons.

Another high impact design optimization step has been made in the process control software with the Flexible Process Interface (FPI). This allows for a virtual limitless process control environment. Every process cycle you desire or will desire in the future can easily be composed by yourselves.

Furthermore the simple way of representing the process ensures you always know what is happening , what is going to happen and why it is happening.

Additional software tools are available for developing processes off-line on your desktop computer.Graphic representation of the measured values (pressures, strokes, forces) can be selected to be shown on screen during the process for the operators or engineers to monitor the process and interpret the behaviour of the balloon being blown.

An innovative system lets the user exchange the split mold heat and cool blocks without the use of any tooling in under 10 seconds.  Below video shows the heat/coolblock modules fully automated exchange system
