Expertise.

Individuals with an idea to develop, entrepreneurs, small and medium-sized businesses, and large companies. You can contact us at the earliest stages or with a project already underway. We adapt the scope to your needs and work with your teams when the project calls for it.

Yes. We can start from an idea, drawings, a prototype or an existing product. We review the work already completed and define the next useful steps from your current position.

Yes. A task can focus on a component, mechanism, simulation or component integration. We define its scope and interfaces with the rest of the product so that a focused assignment moves the project forward.

No. Your need may involve a single discipline or several. We identify the skills needed for your objective, such as exploring a concept, improving a component or preparing it for manufacturing.

Describe the problem, how the product will be used and what you have developed so far. Sketches, photographs, drawings and test results can help. Known constraints and your deadline make it easier to define the next steps.

The scope, deliverables and validation stages provide the basis for an estimate. The budget and schedule also depend on testing, sourcing and how far the project has progressed.

Depending on the assignment: concepts, 3D models, drawings, a prototype, an analysis report or manufacturing documentation. The content and formats are agreed at the start so that the results support the next stage of your project.

Results are compared with the criteria agreed for that stage: function, use, mechanical behaviour or manufacturing. Remaining uncertainties help determine whether to proceed, revise the design or run another test.

Gather current drawings, material specifications, tolerances, intended quantities and inspection criteria. Discussions with the manufacturer help check feasibility before finalising the design or commissioning tooling.

Start with uncertainties that could change the concept, then check them with a focused study or test before detailing the entire design. Distinguish design, prototype, tooling and manufacturing costs: the unit price alone does not represent the cost of the project.

No. A description of the problem, intended use and known constraints is enough to start structuring your requirements.

It can lead to a proof of concept. Its construction and validation points depend on the uncertainties to resolve.

We compare them against the same need: required functions, available space, manufacturing, cost and uncertainties. This makes trade-offs visible and helps identify which options deserve further development.

Yes. A problem with use, assembly or manufacturing can be the starting point. We examine the functions to preserve and the constraints to improve before proposing changes to the concept.

An idea still needs to be assessed against materials, loads, available space and manufacturing. Initial studies identify uncertainties and help decide what needs checking first.

It tests a specific function, such as a movement, locking mechanism or interaction. A simple assembly can answer that question before work begins on the details of the final product.

Yes. We use available drawings, models or prototypes to identify improvements and the interfaces that must be retained.

The documentation can support prototyping or production. Manufacturing, testing and industrial support are specified within the agreed scope.

Drawings, CAD models, sketches, photographs and observations from an existing component can help. We identify missing information for the requested work, particularly interfaces, loads and functional dimensions.

The choice depends on function, loads, environment, weight and the manufacturing process. Assembly and cost constraints are also compared to identify a material suited to the product.

They define acceptable dimensional variations in manufactured parts. In an assembly, these variations affect clearance, guidance and clamping. Tight tolerances should therefore meet a functional need.

The geometry and specifications are assessed against the intended process. Access, functional surfaces, tolerances and assembly steps are reviewed to prepare documentation consistent with manufacturing and inspection.

Identify the parts that need inspection, cleaning or replacement, and the access required. Fasteners, disassembly and cable routing should account for these tasks and the operating conditions.

Not always. A simple assembly may be enough to check a movement. Representative form and ergonomics matter when testing product use.

Not necessarily. Materials, tolerances, assembly and the production process may need a separate industrialisation stage.

A prototype can check a mechanism, handling, available space or component integration. Tests are chosen for the decision to be made, with explicit limits related to the material and how the prototype was made.

Each test can reveal something to improve or an assumption to revisit. Successive versions make it possible to test changes and develop the design using concrete observations.

Yes. We examine its construction, results and the difficulties encountered. Changes are then focused on the functions or operating conditions that still need checking.

Before testing, define the function, operating conditions and expected result. Observations can then inform a decision: keep the solution, adapt it or carry out another test.

The prototype and tests should represent the actions and conditions being assessed. Having relevant users handle the product can reveal difficulties with handling, understanding or assembly, which can then guide design changes.

Available geometry, proposed materials, loads and operating conditions. Missing assumptions are clarified before calculations begin.

It compares variants and identifies areas to examine, helping focus testing. Confidence in the results depends on assumptions, material data and model validation; a calculated result alone does not validate the product.

It can study stresses and deformation in a model under defined loading conditions. Interpretation depends on the assumptions and the design question the analysis needs to answer.

Supports, contacts and loads describe how a component interacts with its surroundings. An unsuitable representation can substantially change the results, even when the geometry appears accurate.

We examine how results change with element size and distribution. The quantity relevant to the decision should stabilise; highly localised peaks also require a review of geometry and applied conditions.

Yes. Variants can be studied under comparable conditions to understand their differences. This guides design while accounting for manufacturing constraints and the tests still needed.

A fatigue study can estimate the effect of repeated loads when the operating cycles and material data are appropriate for the case. A static calculation alone cannot establish service life; assumptions and the need for physical tests must be considered.

Ideally before fixing the geometry or commissioning tooling. We can also analyse difficulties with an existing component.

We have coordinated tooling, injection trials and initial production runs. DOMTEKNIKA’s role and the partners’ roles are agreed for each project.

Geometry affects filling, cooling and ejection. Considering wall thickness, draft and tooling access during design helps limit changes later in development.

Not always. A geometry developed for a prototype may need changes to its walls, ejection or assembly. The production material and process must be considered before specifying tooling.

The choice depends on use, loads, temperatures, environment and the processing method. Material properties are assessed together with component geometry and product requirements.

Dimensions, appearance, assembly and function are assessed against the intended requirements. Observations identify any changes to geometry, tooling or process needed before production continues.

It can be, but tooling cost, quantities, geometry and material must be compared. The choice depends on total cost and product requirements, before investing in a mould.

Yes. We can focus on interfaces and mechanical integration, coordinating with your project teams or partners.

Required functions, selected components, power constraints and available drawings. We then define the necessary development work and checks.

It covers component placement, power, connections and interfaces with the mechanical design. Any electronics design or software work needed is defined in the project scope.

No. Work can start from required functions or components you already have. Data sheets, dimensions and power requirements then help define the architecture and integration constraints.

It determines available space, mounting, cable routing and access to connections. It also contributes to heat removal; these constraints are addressed together with the product’s operating conditions.

Interfaces are checked progressively: power, control, movement and behaviour during use. Tests should match the required functions and intended operating conditions, with criteria defined in advance.

Account for consumption in each operating mode, the time spent in those modes and the usable battery capacity. Standby consumption matters too. An estimate based on the intended use should then be checked against measurements on the system.
