BASEline
The Baseline series combines a compact design and convenient operation and can be used optimally for a large number of projects in Low Pressure Moulding.
Various mechanical components can be put together as required.
The adapted melting device with double-acting piston pump and a melting capacity of approx. 1kg / h enables optimal processing of small to medium shot weights and / or quantities. The available clamping force of 9 / 12kN is suitable for moulding surfaces up to approx. 3000mm².
By using the Siemens S7-1200 control with touch panel, the series offers the same ease of use as the larger series.
FLEXline
The Flexline series offers maximum flexibility thanks to the modular structure of various variants and expanded options for implementing 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 including hot runner systems with different nozzle geometries and arrangements are available.
The melting units can be optimally 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 our innovative "plug-and-play" system.
Extensive peripherals and additional options complete the system.The Flexline can thus be optimally tailored to the requirements of the respective project.
LABline
To get started with the technology, for prototyping new projects and manufacturing small series, the Labline offers a selection of small devices tailored to the requirements of the Low Pressure Moulding technology. The basis for this is the manual moulding gun with a 0.2l tank for filling with the moulding granulates.
In order to achieve process stability and reproducibility even with this manual processing, a time control can be connected. Two different clamping devices are available for convenient handling of sample and pre-series tools.
CUSTOMline
With the Customline, the Low Pressure Moulding equipment can be individually tailored to your project requirements.
Individual components from the other series can be used as well as a complete special design. Special requirements of your production can be taken into account here as well as the integration into production lines.
For installation in special systems, individual system and tool components and the corresponding support can be provided in cooperation with a special machine manufacturer.
LPM Extruder
Special HotMelt extruders have been used in the LPM process for several years. They allow the moulding materials to be melted very quickly and as required. This prevents the macromolecules of the materials from breaking apart („cracking“) if they have to be kept at processing temperature for a longer period of time.
OptiMel has developed an extruder system that is specially adapted to the conditions and parameters of LPM. A special design uses the advantages of an extruder when melting the material and realises the injection via an additional piston unit.
With this method, pressure peaks can be avoided and the advantages of extruder machine systems can be combined with the requirements for processing sensitive electronic components.

Operation and safety concept
Manual clamping system with pneumatic support and locking during the moulding process.
The pneumatic clamping unit is controlled via two-hand operation. In combination with a downstream safety valve, an operating and safety concept is created for a one-person workplace.
The work area towards the operator is secured by a light curtain. Intervening while the clamping unit and sliding table are moving leads to a stop. In combination with a capacitive start button and safety valve, a safe and convenient concept.
