Hotmelt Machine FLEXline

Maximum flexibility for the highest demands

The FLEXline series offers maximum flexibility by the modular design of different configurations as well as extended possibilities for the realisation of special functions.

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

In addition, various application systems up to hot runner system with different nozzle geometries and arrangements are available.

The melting units can be optimally adapted to the requirements of the respective project with different melting and conveying systems and, in the event of different or changing project requirements, can also be switched at any time by our "plug-and-play" system.

Extensive peripherals and additional options round off the system.

The FLEXline can thus be optimally adapted to the requirements of the respective project.

  • For medium to large series productions
  • Flexible, project-specific design of the equipment possible
  • Extensive special options and peripherals available

FLEXline models

Optional machine accessories and peripherals

 Devices for mold temperature control 

Depending on the application, various devices with working ranges from -10°C to + 60°C and flow rates of up to 20l/min are available.

Air nozzles for demoulding

Air pulses in the upper part of the mold to keep the encapsulated components in the lower cavity when the mold is opened.

Remote maintenance

Router and ethernet interface with secure and fast access for support in the event of a malfunction or for transmitting program adjustments.

Pressure monitoring for application head

A pressure sensor in the application head measures and monitors the moulding pressure. Print curve display and archive in machine PLC.

Height adjustment

Allows electrically controlled, stepless adjustment of working heights.

Lights for work area

For additional illumination of the handling area.

Automatic filling

Conveyor unit for automatic refilling of the melting tank, incl. sensor for monitoring the fill level as well as storage container for the granulates.

Signalling column

Indication of the operating status by five segments in different colors and light modes.

Machine configurator

Use our machine configurator to put together your individual Low Pressure Molding FLEXline machine, tailored to your manufacturing processes.     

Low Pressure Molding tools

The decisive factor for the technical implementation of any project is the corresponding moulding tool. Each is individually developed, designed and manufactured for the respective project.

Our experienced designers and project managers are always available to consult you!

Hot melts for electronics encapsulation

There is the right material for every application. Amongst our hotmelt granulates we also have the right material for special projects and areas of application.

Find out more about the various types of materials.

Virtual LPM Studio

With our OptiMel Studio, we added a digital space to our facilities in 2020.

We are thus just as well positioned for virtual trade fairs and lecture events as we are for individual online seminars and training courses.

In addition, individual consultation appointments can also be organised. For example, you can get to know our machine system in detail, book operator and maintenance training courses or take part in a tool sampling - and all this conveniently from the comfort of your own workplace.
