Mechanical Engineering is the step following the Design phase. This phase can be devided into three parts: basic engineering and 3D, functional prototype and product prototype.
Basic Engineering is needed to develop a 3D-CAD design into the level that allows a functional prototype to be built and tested. We develop solutions to all functional wishes and demands.
Product architecture – the internal configuration of all components – considers the necessary variations in external appearences and ultimately the ‘design for assembly’ and ‘circularity’.
The test results of the functional prototype are considered in ‘detail engineering’. We decide on the proper materials and production technologies, with an eye on the demands for function, strength, lifetime, costs, design and the intended volume of the test run. All details are considered in relation to intended production technologies.
Our FEM software (Finite Element Method) allows us to carry out calculations about the mechanics of a design in an early stage. By using simulations we calculate the mechanical stiffness and strength of the various components and final structure of a design, as well as the modal analysis (eigenfrequencies).
Product prototypes are subsequently made and tested.
The test results are then embedded in the final details. The details that are required for production are included in a Bill of Materials and in the instructions for assembly. A production prototype is finally constructed, using sample molds when possible.
Prototyping is essential in order to obtain a successful production process. The test results are a guide to the next decisions to be made about investments.
In the designphase we develop a Proof of Concept, also called a Proof of Principle or a Minimal Viable Product. This aspect demonstrates the the way the product operates. At the same time mock-ups and renderings are made in order to enable the client and the potential customers to judge the design.
After approval has been obtained the decision can be made to develop a functional prototype. The relevant and basic functions for the end-user can be tested this way.
If all conditions have been met the product prototype that embodies all functional demands as well as the details for production can be developed
A product prototype represents the final product to be produced. The product prototype is subjected to all relevant tests.
Finally the production prototype is built, often by using the sample moulds.
The approval of the production prototype substantiates and justifies investments in moulds and means of production.
Besides conventional technologies like milling and lathing for prototyping we apply modern technologies like the latest Rapid Prototyping and 3D Printing materials and techniques. In these acitivities we rely on our vast network of suppliers.
