Design and Construction Housing

development step 3

When it comes to a functional and modern housing for customer-specific electronics, the right know-how in all of the steps in production is needed - from the first idea sketches, through technical design variants, to the elaborate design and 3D printing for the electronics housing.

The designers and constructors develop draft designs for innovative products or create redesigns on existing housings and technical constructions. The interaction of product design, construction and electronics development minimises the risk of errors in the final product.

Building a Prototype

Form Follows Function

The development engineers, designers and constructors work together with the customer to develop a design concept with basic requirements (design, function, ergonomics, etc.) for the future product. Not only are aesthetic functions taken into account, but also functional requirements for usability, manufacturability and service life. We always focus on your customers and target markets, on top off keeping a close eye on feasibility. A selection of concepts for the functioning product is created in the forms of sketches and renderings.

The preferred design is further refined, modelled and technically worked out in detail using the 3D CAD program SolidWorks. The photorealistic 3D product visualisations give a precise idea of ​​what the product will look like when finished. At the same time, mock-ups (design prototypes) can be created on request, which present the product in a tangible way and create opportunities for form and function testing. In the design process, we calculate all relevant housing parameters in terms of shape and material.

A prototype is the tangible vision of the product. With functional prototypes, usability, material, assembly, maintenance, form and functionality are tested under real and life like circumstances.

In House Rapid Prototyping

pironex uses its own 3D printers (SLA and FDM) and milling machines to quickly and easily create components that can be used for testing or for model building purposes.

With rapid prototyping via 3D printing, you receive functional and resilient prototypes in a short period of time. In this way, problems and weaknesses are identified at an early stage, leading to the design or function being corrected before production.


  • SLA and FDM 3D printing
  • Creation of resilient milled parts
  • Functional samples for function and handling tests
  • Functional samples for marketing purposes

Transition to the Serial Product

In the "Transition to the series product" phase, the development engineers optimise the production of the product according to the needs and the available production possibilities.

The required customer-specific tools and moulds (e.g. injection moulding) for series production are developed and optimised with the production companies for injection moulding.

Preparation for series production:

  • Creation of process-optimised technical drawings (single part, assembly and tolerance drawings)
  • Handover of production documents for the customer
  • Accompaniment of series production at the service provider
