Gross Schaltschrankbau supports companies with custom control cabinets for special-purpose machines, test rigs, pilot plants and early development phases. Planning, manufacturing and testing are aligned with the agreed project scope. Changes remain traceable, interfaces are clarified early, and a later transfer to small-batch or series production can be taken into account from the outset.
Project type
One-off, prototype or small batch
Application
Special-purpose machine, pilot plant, test rig, R&D
Basis
Your documents or a jointly defined engineering scope
Use cases
This manufacturing model is particularly suitable when requirements are still project-specific, no approved series exists, or technical findings from the first build are to be incorporated into later variants.
Special-purpose machines and custom plants
When layout, components, interfaces or installation conditions have to be tailored to a single project.
Test rigs and research
When flexible adjustments, additional measuring points or step-by-step technical validation are required.
Pilot builds ahead of series production
When manufacturing documents, assembly sequence and test concept are first to be verified on a real build.
Project workflow
The exact split of responsibilities depends on whether Gross Schaltschrankbau only manufactures or also provides engineering and testing services.
A one-off does not forgive standardisation. There is no pre-series to reveal a fault and no second unit to spread the effort across – every decision takes effect exactly once, but immediately.
That is why work starts with the data, not with the material: what is available, what is missing, what is an assumption? Open points are identified and documented instead of being decided in the workshop.
Prototypes are also learning objects. Whatever stands out during the build – tight installation space, an impractical terminal position, missing spare capacity – is fed back into the documentation. That is exactly what makes the follow-up order reproducible.
The result is a tested one-off with documents that match the as-built state – the prerequisite for turning it into a series later on.
01
Check documents, deadline, quantity and application.
02
Agree on services, interfaces, standards and verifications.
03
Finalise schematic, bill of materials and layout as binding.
04
Machine, assemble, mount components and wire.
05
Carry out and document the agreed inspections.
06
Transfer changes to the follow-up build or series.
Decision guide
Quality & trust
The first build does not just deliver a result – it makes assembly sequences, installation space, component selection and test requirements verifiable in practice. For this to become a sound basis for follow-up orders, changes, deviations and approvals must be documented traceably.
Required project information
Not all documents need to be complete yet. However, open points should be visible so that effort, responsibilities and risks can be assessed realistically.
