Clearly defined functions, interfaces, and processes

Understanding assembly production – how components are turned into ready-to-install modules

Combining mechanical, electrical, and mechatronic components into a functional assembly is more than just assembly. Clearly defined functional units are created in assembly production. To achieve this, we combine mechanics, electronics, pneumatics, and sensor technology in a targeted manner to create not a "building block" but a ready-to-connect module – tested, documented, and ready for series production.

This enables our customers to significantly reduce internal complexity. Instead of having to plan, check, and assemble dozens of individual parts, they receive an assembly that reliably maps all functions, tolerances, and interfaces. As a system supplier , we consistently think in terms of modules and design them so that OEMs can integrate the assemblies directly into their line or end device.

Our design-to-deliver approach

Your added value with us as your production partner

As a production partner, we support OEMs along the entire value chain – from technical clarification, development, procurement, and manufacturing to testing, logistics, and series delivery.

Our services are seamlessly integrated. Consulting, engineering, supply chain management, and production follow a clearly coordinated process with defined responsibilities. This enables us to deliver functionally tested, ready-to-install assemblies that can be reliably and reproducibly integrated into existing production environments.

For you, this means fewer interfaces, less coordination, and a production partner who takes responsibility from the initial idea to series production.

Structured processes for reproducible quality

Assembly processes that reduce complexity

In assembly production, assembly determines whether components can be turned into a module that is ready for series production. That is why we structure our assembly processes in a clear and comprehensible manner. We clearly separate mechanical, electrical, and mechatronic work steps and coordinate them precisely. Defined procedures, fixed test points, and clearly regulated handovers ensure that we assemble every assembly to be functionally reliable—regardless of quantity, variety, or technical complexity.

Mechanical
Pre-assembly

We assemble mechanical components into stable functional assemblies. We work with defined torques, clear processes, and documented quality. This ensures reproducible assembly that is suitable for series production.

Electrical
Integration

From cable assembly and sensor integration to wiring, we connect electrical components in a structured manner and in accordance with ESD standards. We ensure consistently high functional reliability through clearly defined tests.

Mechatronic function modules

We combine mechanics, electrics, and functionality into ready-to-connect modules. We thoroughly test each module, document the results, and build it so that OEMs can integrate it directly into their line or end device.

Practical examples

Mechatronic assemblies in use

We deliberately do not mention any customer names here – but many of the situations described will be familiar to you. OEMs in mechatronics often face similar challenges: increasing complexity, scarce resources, demands for shorter development cycles, and the need to establish reliable series production processes. This is precisely where we take responsibility.


Case study An OEM in the mechanical engineering sector required several mechanical assemblies for a series product. The assemblies consisted of numerous individual parts, had to be assembled with defined torques, and had to be reliably tested. Internally, the wide variety of variants led to high assembly and coordination costs.

Implementation by FMA
We took on the mechanical pre-assembly as independent functional assemblies. The assembly processes were standardized, procedures clearly defined, and quality assured directly in the assembly process.

Added value for the customer
The assemblies could be reproduced in series production and integrated directly into final assembly. Internal costs at the OEM were reduced and process stability was increased in the long term.


Case study Cable assembly, electrical components, and sensor technology had to be reliably integrated into a technical device. The requirements for functional safety, ESD-compliant assembly, and testability were high, and at the same time, the assembly had to be delivered ready for installation.

Implementation by FMA
We took care of the electrical integration – from cable assembly and sensor integration to complete wiring. Assembly was carried out in a structured manner, in compliance with ESD standards and with defined electrical tests.

Added value for the customer
The customer received an electrically tested assembly with clearly documented interfaces. This reduced the burden on internal production and significantly improved the functional reliability of the assembly.


Case study An OEM required a mechatronic assembly that combined mechanics, electrics, and function in a ready-to-connect module. In addition to assembly, final testing, documentation, and a smooth handover to series production were required.

Implementation by FMA
We took on the complete implementation of the functional module—from procurement and assembly to final testing and documentation. All components were combined into a tested, production-ready assembly.

Added value for the customer
The OEM received a ready-to-install, functionally tested module that could be integrated directly into the line. Development and industrialization costs were reduced and series production was accelerated.

In-house production or production partner?

Make or buy – making informed decisions

When manufacturing assemblies, OEMs are regularly faced with the question of whether components and modules should be manufactured in-house or sourced externally. The decision between make or buy affects capital commitment, time-to-market, flexibility, and long-term scalability. The following comparison shows typical aspects of both approaches and serves as a guide for making an informed, economically sound decision.

FAQs

You have questions, we have the answers

Questions that frequently arise before and during a collaboration. And which we are happy to answer for you at any time.

Assembly production refers to the structured assembly of mechanical, electrical, or mechatronic components into a functional unit. The goal is to produce a tested, ready-to-install assembly that can be integrated directly into a production line or end device.

In practice, OEMs often opt for external assembly manufacturing when complexity, variant diversity, or testing requirements lead to excessive coordination efforts internally. The benefit stems less from the number of units produced than from the reduction in the burden on internal processes.

Mechanical pre-assemblies, electrically integrated assemblies, and complete mechatronic functional modules are manufactured externally. It is crucial that the assembly is clearly defined, testable, and designed for series production.

Quality is assured through defined assembly processes, specified test points, and documented procedures. Certified processes ensure that assemblies can be manufactured reproducibly and delivered reliably.

The project usually starts with a technical clarification of the requirements. This is followed by process definition, industrialization, and gradual transition to series production—with clear responsibilities and a transparent process.

Manufacturing ownership means that a production partner assumes responsibility for the industrial implementation of the assembly. OEMs benefit from fewer interfaces, reduced coordination effort, and stable series delivery.
