Arrange for various tests, including mechanical, mechatronic, photometric, and thermal, on sample devices and integrate the results into the design. Demonstrate a thorough understanding of the molding injection process and tooling technology. Proficiently use CAD software (specifically Catia V5), Design for Assembly (DFA), and Design for Manufacture (DFM). Clarify and define design requirements with the customer by creating detailed project descriptions and analyze design expenditure. Develop design drafts based on CAD data provided by the customer, taking into account device design, assemblies, parts, and technical and economic aspects. Create design solutions considering functional, material, technical production, and economic aspects; detail selected designs. Carry out and coordinate detailing work for devices, assemblies, and parts, and prepare all necessary 3D documents. Arrange for tests on sample devices, including mechanical, mechatronic, photometric, and thermal, incorporating the results into the design process.
