3D product development

We use functional samples, also known as working prototypes, to check whether the technical design meets the functional requirements using the intended materials and the intended manufacturing process. Important to all functions, load-bearing capacities and material properties of the end product can be tested using these components in the Engineering Validation Test (EVT). With electrotechnical prototypes, we can provide a functional sample during the development phase. Evaluation includes feasibility, electrical and mechanical validation, thermal and environmental stress tests to assess product performance under extreme conditions, validation of materials, and ensuring compatibility, durability and regulatory compliance.

On request, we can also prepare industry-specific validation reports in cooperation with accredited external partners.

We use visual prototypes to check the manufacturability, reliability, quality of appearance, look and – less frequently for us – feel. The models are usually created using 3D printing and are made from near-series materials for the design validation tests (DVT). They give an impression of size and shape, whereby we focus on the basic features. 3D techniques such as SLA (stereolithography) and FDM (fused deposition modeling) are cost-effective and quick-to-use manufacturing processes for producing these prototypes.

As part of design and technical validations, we also create complete application samples such as the reworking of vehicle seats, furniture and technical assemblies.

In the transition to series production, we create high-resolution, near-series prototypes. They largely correspond to the products from series production and have congruent or very similar material properties. In product validation tests (PVT), we then evaluate the readiness for series production, compliance with consistent quality and subsequent processing. In the case of electrical components, the initial start-up process is carried out using near-series prototypes. We then conclude product development with a pilot series in which all production parameters are validated.

We work with risk management protocols such as FMECA or FAI to identify risks such as dependency on a single contract manufacturer for the procurement of a specific component.

All processes are useless without the interpretation of the data. This is why we work transparently with our customers, evaluate the results together and optimize products and processes. This is also where our knowledge and experience come into play: the OKE Group is at home in many industries and knows the very different requirements for components and assemblies made of plastics and metals. We recommend changes to materials or tools, discover potential savings and weak points in manufacturing processes.

Together with our customers, we work on optimizations until everything is perfectly coordinated.
