We develop and manufacture custom HMI assemblies – from cover glass and PCAP touch and touch lamination through to optical bonding, mechanics and full integration including electronics and interfaces. All critical process steps are carried out reproducibly and fully documented in Germany.
Our dynamic engineering team stands for fast implementation, tailored solutions and a deep understanding of the requirements of modern HMI systems – whether in industrial automation, medical technology, defence, automotive or outdoor applications.
As a full-service partner we take on the complete backend production for display modules – from sourcing and qualification through incoming goods inspection and QA to touch lamination, optical bonding in our ISO 7 cleanroom, cleanroom assembly, kitting & electronics as well as final testing, packaging and shipping. Your benefit: one partner, one process, one quality standard.

Maximum process reliability, short response times and 100% quality – for high-end HMI assemblies “Made in Germany”.
Modular in structure yet fully integrable: from the glass/touch front via optical bonding to a ready-to-install unit including mechanics and electronics.
Optical bonding permanently links display and cover glass – for maximum readability, reduced reflections and a robust, long-lived assembly. Depending on the application we use OCR or OCA and control the entire process (preparation, bonding, curing, inspection) under controlled conditions.
Precise bonding of cover glass & touch sensor – autoclaved and long-term stable.
Process reliability for optically demanding assemblies – reproducible and stable.
Sensor design, controller & firmware – robust, precise, industry-grade.
Design + protection + visibility – tailored to ergonomics and look-and-feel.
Ready-to-install modules instead of single parts – including kitting & electronics.
In modern HMI systems, optical bonding is a key quality factor: by bonding the display to the front glass (or touch), you get an optically, mechanically and functionally optimised module – free of air gaps, low reflection and highly robust.
Our OCR process uses a liquid, transparent silicone material that is applied between display and front unit and then thermally cured. The 2-part silicones we use have been developed specifically for display applications – with outstanding optical clarity, flexibility and long-term stability.
Advantages of the OCR process:
Highly flexible in use:
Here we use highly transparent adhesive films which are laminated between display and glass/touch unit in vacuum processes without air inclusions. The result is a permanently bonded, optically high-grade and very flat stack-up.
Advantages of the OCA process:
Touch lamination permanently and precisely bonds projected capacitive touch sensors (PCAP) with the custom cover glass – optionally complemented by functional films. The process is carried out in our ISO 7 cleanroom followed by autoclaving.
For optical bonding and touch lamination even smallest particles lead to visible defects. That’s why all key processes are carried out entirely in our own ISO 7 cleanroom – from first handling to finished assembly.
For systems that must perform reliably under challenging light, temperature, vibration or quality requirements.
Whether prototype, small series or volume production – we evaluate stack-up, process choice (OCR/OCA/lamination) and feasibility and deliver a robust, optically clean solution.
We support you already in the early concept phase – from the selection of suitable display and touch technologies through the definition of the optimal bonding stack-up to transfer into series.
In doing so we take into account not only optical quality but also environmental conditions, lifetime, service concepts and economic aspects across the entire product life cycle.
Briefly describe your HMI assembly – we will get back to you with follow-up questions or a proposal for a meeting.
