Enclosure concept & 3D design
Housing concept developed around the electronics, with 3D fit checked against real components.

Enclosure design and simulation
for the world your product actually lives in.
The enclosure decides how a product feels, how it survives and whether it can be manufactured. We design the mechanical around the electronics — fit, thermal paths, structural strength, assembly access and materials — and verify it by simulation before any tooling is committed.

- Assembly-aware
- Manufacturing drawings
Why enclosures cause late reworkA housing is a thermal,
A housing is a thermal,
structural and manufacturing decision.
Enclosures fail in ways that look cosmetic until they are not: a board that will not fit because the connector moved, a sealed housing that traps heat, a lid that cannot be assembled without damaging the electronics, or a material choice that cracks in cold weather.
We design the mechanical with the electronics from the start. Fit, thermal dissipation, structural integrity, assembly sequence and material behaviour are checked together, and verified by simulation rather than by building one and hoping.
Tooling is expensive to change. Simulation and a physical prototype before tooling protect the one-off cost, which is usually far larger than the engineering saved by skipping the checks.
- 01Fit verified, not assumed
Board, connectors, display and buttons checked in 3D with real component dimensions.
- 02Thermal paths designed
Heat sources and dissipation paths modelled so the enclosure does not trap heat.
- 03Assembly considered
The enclosure designed around how it is actually opened, closed and serviced.
- 04Tooling protected
Simulation and prototype results used to validate the design before tooling is cut.
- 3D fit checkBoards, connectors, displays and controls verified against real component dimensions.
- Thermal modelledHeat sources and dissipation paths simulated against the sealed assembly as built.
- Assembly-awareOpening, closing and service sequences checked so the product can be built and repaired.
- Manufacturing readyDrawings, tolerances and material guidance produced for the selected process.

Capabilities
Enclosure and mechanical capability
The mechanical design is developed with the electronics, not handed a finished board to work around.
3D enclosure design
Parametric housing design with fit verified against actual component geometry.
Thermal engineering
Heat paths, spreading and sealed-assembly temperature rise simulated and validated.
Structural analysis
Impact, vibration, drop and deformation analysis for the target environment.
Material selection
Thermoplastics, elastomers and finishes selected for environment and process.
Ingress & sealing
Gaskets, seals and enclosure design achieving the required ingress rating.
Human factors
Grip, button feel, indicator visibility and one-handed use considered in the design.
Manufacturability
Draft, wall thickness, ribs and parting lines designed for the chosen process.
Product appearance
Form, texture and assembly-line finish developed alongside the mechanical engineering.
Structural and thermal work on the board itself sits in PCB layout engineering, and 3D-printed form studies in 3D prototyping.
Our process
How an enclosure is developed
Requirements, concept and fit, then thermal and structural verification, then tooling-ready drawings.
Requirements & concept
Environment, ingress, handling and appearance requirements agreed, then a concept selected.
Design concept3D fit & layout
Board, connectors, controls and display fitted in 3D and the internal layout fixed.
3D assemblyThermal & structural check
Thermal paths and structural loads simulated against the real environment.
Analysis resultsPrototype & drawings
Prototype verified for fit, temperature and handling, then tooling drawings released.

Technologies
Mechanical design and simulation
The manufacturing process is chosen against volume, geometry and cost, because it determines the whole approach.
- 3D CADParametric enclosure design with fit and interference checked against component geometry
- Thermal simulationHeat source modelling, conduction, convection and sealed-assembly temperature rise
- Structural simulationImpact, drop, vibration and thermal deformation analysis
- Material databaseMaterial properties for temperature, impact, UV and chemical resistance
- DFMDraft, wall, rib and parting-line guidance matched to the chosen process
- Prototyping3D printed and machined prototypes used to verify fit and handling before tooling
Material choice has to suit the process as well as the environment. A material that performs well in simulation can behave poorly in a thin moulded wall, so both are checked together.

Ask about your requirements →What enclosure design services do you offer?
Enclosure concept and 3D design, thermal simulation, structural analysis, material selection, ingress and sealing design, and manufacturing-ready drawings.
Do you design the enclosure around our electronics?
Yes. The mechanical design is developed with the board, connector and control layout known, so fit, thermal paths and assembly access are resolved together rather than after the board is frozen.
Can you check fit before tooling?
Yes. 3D fit and interference are checked against real component geometry, and a prototype is normally built and verified before tooling is committed.
Which manufacturing processes do you design for?
Injection moulding, die casting, sheet metal and machined assemblies. The process is selected against volume, geometry, cost and environmental requirements, and the design is tailored to it.
Do you handle ingress protection?
Yes. Enclosure sealing, gaskets and compression are designed to the required ingress rating, and the sealing solution is documented for the assembly house.
Can you redesign an existing enclosure?
Yes. We can review an existing housing for fit, thermal performance, structural strength, manufacturability and appearance, and propose a redesign or a focused improvement.
