Press report

LPM in DICHT! magazine

The new DICHT! magazine was published on November 18, 2021 - the trade journal on all aspects of sealing and gluing.

Low Pressure Moulding - represented by OptiMel - is presented in 2 statements as an interesting alternative to classic sealing solutions (pages 12 and 18).

A comprehensive article will be published in the upcoming magazine 1.2022 , which will illuminate the LPM, its possibilities and advantages in the area of ​​electronic moulding in detail.


Fairs and congresses

productronica Munich live

After almost all trade fairs last year took place exclusively virtually, the first face-to-face events are starting again this year.

As a long-standing exhibitor, we are of course present at productronica in Munich and can once again present and network ourselves live and "in color".

This year we will show the latest features of our Flexline machine series as well as our innovative LPM equipment with integrated induction for impermable moulding on metallic inserts, which was further developed by the requirements of the first project implementations.

We look forward to an intensive exchange, exciting projects and interesting new contacts.

We cordially invite you to visit us at our booth 101, hall B4 - you can request your personal ticket voucher using our contact form.


OptiMel supplies 
climate-neutral materials

The compensation of CO² emissions plays an important role in climate protection. Germany targets to be climate neutral by 2045, Europe by 2050.

For these purposes, it is not enough to rely on political action. In order to achieve them, everyone has to contribute. The companies in the industrial state of North Rhine-Westphalia in particular play a decisive role.

We have been a climate-neutral company since 2019 and have again drawn up a CO² balance for 2020, on the basis of which we identify potential savings and compensate for the remaining emissions. Here, an even more detailed database was used for analysis in order to be able to carry out the most precise assessment possible. Savings potentials were implemented for 2020 and additional influencing factors were compensated. .

The next logical step was to work on the climate neutrality of our products.

Since June 1, 2021, we are able to offer the Technomelt moulding materials from Henkel climate-neutral.

Henkel itself has been committed to sustainability for decades. Sustainability is also part of the strategic framework for holistic growth with which Henkel aims to be successful over the next decade. Along the entire value chain and in cooperation with its partners, Henkel aims to become climate-positive by 2040. To achieve this, the company is setting far-reaching goals, such as purchasing 100% electricity from renewable sources by 2030 and working with customers, consumers and suppliers to save 100 million tons of CO2 between 2016 and 2025. If you would like to find out more about Henkel's initiatives and goals in the area of ​​sustainability, see here: Sustainability report (

OptiMel complements a further contribution in the supply chain with its climate-neutral action.

Joint commitment increases. It protects our climate and our environment. In the end, we all benefit.

CO² balances for our machines and tools are already in progress and we hope that we will soon be able to offer this added value.

Fairs and congresses

First electronica virtual

In 2020 electronica, Munich took place as a virtual event for the first time.

This change, made necessary by the corona pandemic, brought many challenges as well as opportunities for new concepts and ideas.

Of course the pioneers were part of it. With the support of our long-standing partners in trade fair construction - Wiesner Messearchitektur and Plan3 - a concept was developed to implement interesting and profitable content in virtual space for existing and new customers, interested parties and business partners.

The result was the OptiMel studio for live meetings, which will continue to be used intensively after the trade fair - for workshops, presentations, project consultation, sampling and acceptance appointments.

Furthermore our appearance at the fair was a designed in the form of a virtual showroom - you can take a look at it again here:


 Reasearch project 
„Voyager PV“

OptiMel is an industry partner in the new research project "Voyager PV", which aims to integrate electronics and inverters into solar modules in order to create more efficiency and reliability of PV systems with lower costs at the same time.

Adhesion on metal 
with induction

With the Low Pressure Moulding technology, it was previously not possible, or only possible with great effort, to produce impermable mouldings on metallic components. 

With our innovative equipment, adhesion on metal in the LPM technology can first be realised efficiently and reliably in one step. 

It enables targeted heating of the components directly in the tool and thus the formation of adhesion bridges in the molding process without time-consuming pre- or post-processing. 

With integrated induction equipment and a specially developed modular tool system, a qualitative and flexible solution was created that can be tailored to the requirements of the individual project.   

The press also reported - on pages 34 - 36, the Electronics Production and Testing Technology magazine presents our innovation.

Maschine system

Plug and play 
for melting units

A project-specific melting performance and material processing is an important factor for stable processes, protection of material and corresponding long-life cycle of the equipment. 

In order to offer the possibility of adapting the melting devices flexibly to the respective project, we have developed our "Plug and Play" system. A special hybrid cable and appropriately assigned Han Yellock connector as well as master-slave communication between machine and meltong unit enable a quick change and ensure that the machine programme automatically switches to the connected unit and the corresponding parameters and operating screens are loaded.

Machine system

Low Pressure Moulding 

Since 2014/15, processing with extruders has also been increasingly used in the Low Pressure Moulding. OptiMel has adapted this technology to the conditions and parameters in Low Pressure Moulding and developed a special version with injection via an additional plunger unit. This avoids pressure peaks and combines the advantages of the extruder with the requirements for processing of sensitive electronic components.
