Based on the design, we develop a prototype. Among other things, this step centres on creating a mould design, testing and evaluating it and adjusting it where necessary. We do this using Moldflow, FEM simulations and other advanced tools. With our experience and knowhow in the field of design and simulations, we tend to require only a small amount of try-outs. And of course we aim to get it right the first time! Nevertheless, prototyping is essential preparation for step 4.
