Rapid prototyping

We use functional samples to check whether the technical design fulfills all functions using the defined materials and the intended manufacturing process. For us, evaluation generally includes feasibility and – depending on the component – electrical and mechanical validation, thermal and environmental stress tests to assess product performance under extreme conditions, as well as ensuring compatibility, durability and compliance with legal requirements.

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.

In the transition to series production, we create high-resolution, near-series prototypes with 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. We conclude product development with a pilot series in which all production parameters are validated again. We work with risk management protocols such as FMECA or FAI to identify risks, such as dependence 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 production processes. Together with our customers, we work on optimizations until everything is perfectly coordinated.
