HMI assemblies – from concept to box-build

We develop and deliver complete HMI assemblies that combine everything from keyboards and displays to PCBs, shielding, cables and mechanical housings – all in one tailored, plug-and-play solution. These can be delivered fully assembled or as part-assemblies, ready to integrate into your product. Also known as box-build assemblies, these modules are tailored to your mechanical and functional needs – and often delivered as a single item number.

Scalable plug & play solution

An HMI assembly can take many forms, and is called a variety of terms: HMI sub-assembly, box build, HMI module, complete HMI, etc. An assembly of a user interface may include some or all of these components:

keypad
display
PCB
enclosure, housing or backplate
EMI/ESD/RFI shielding or insulation
cable assembly.

It is your product design, supply chain management and production process that defines the requirements. And our task is to ensure that our delivery to you smoothly integrates with your production line.

How complete can an HMI assemby be?

You decide. We tailor our offering to your specification. Here are some of the most typical scenarios that an HMI assembly can have.

A keypad mounted on a backplate is one of the most common and efficient HMI configurations. It enables fast and easy mechanical integration at your end. The keypad is typically a membrane switch or silicone rubber type, mounted on a metal or plastic backplate – adapted to your product and assembly process.
A more advanced solution with multiple functional layers built directly into the keypad construction – such as EMC shielding, light blocks or environmental sealing. These assemblies are typically delivered mounted on a housing, allowing effortless integration into your product. The construction can be adapted to meet the demands of harsh environments or specialised use cases.
A mechanically and electrically integrated solution combining input and output – typically a keypad with a display. This type of assembly supports efficient signal routing, and is delivered ready for plug-and-play installation into your system.
A complete, self-contained input module – ready for direct electrical integration into your product. These assemblies typically include keypad, display, PCB, wiring and housing – delivered as a tested and documented unit under a single item number.

Rapid prototyping and design support

We support fast development through early prototyping and design advisory. Using technologies like 3D printing, we can provide functional prototypes without tooling costs – ideal for early fit and usability testing. Our engineers work closely with you to ensure the assembly is optimised for the environment in which it will be used, whether that means improved durability, ease of integration or protection from external conditions.

Complete HMI assembly

We offer in-house assembly of HMI solutions across the full spectrum – from simple front foils to fully assembled control panels and everything in between. Our experienced specialists ensure consistent quality and reliability at every step. Whether your solution includes cables, PCBs, connectors, housings or displays, we manage the complete mechanical and electrical assembly as part of a streamlined production setup tailored to your needs.

Save R&D time & resources

Focus your R&D efforts where they create the most value – and let us handle the HMI. We manage the entire development process, including component sourcing, material selection, prototyping, testing and logistics. One partner – all in one place.

Simplify supply chain

With Mekoprint as your HMI partner, you get a streamlined supply chain and full quality assurance. We handle the complete tolerance chain, documentation and testing – so you only deal with one supplier for the entire HMI assembly.

Time-saving assembly

On your production line, you only need to interface with one fully integrated HMI assembly. This reduces assembly time and simplifies both manufacturing and quality control.
