OptiMel FLEXline Low Pressure Overmoulding Equipment

Optimel Flexline LPM machines

The OptiMel FLEXline low pressure overmoulding machines are designed for medium to large scale production. The systems offer maximum flexibility both at the time of purchase and into the future, thanks to the modular structure of the system design, which enables upgrades and add-ons for implementing special functions.

Extensive peripherals and additional options complete the system so that the Flexline can be optimally tailored to the requirements of the particular project. In addition, various application systems including hot runner systems with different nozzle geometries and arrangements are available.

The melting units can be matched to the requirements of the respective project with different melting and conveying systems. In the case of different or changing project requirements, these can be exchanged at any time using OptiMel’s innovative “plug-and-play” system.

The adaptation or addition of individual components is just as possible as special programming or integration into a complete production line.


  • Machines for medium to large serial production.
  • Flexible project-specific combination of machine components
  • Mass pressure adjustable 5-40/60 bar

If high volume production and minimal stoppage time is a key requirement to your business, the automatic filling system that can monitor the level in the melt tank and topping up when required could be exactly what is needed. This system not only saves time in production, but also prevents the machine operator accidentally running the tank out of material, which is a common issue in high volume production.
