This bachelor's thesis focuses on the design of production fixtures for the annual serial production of 300 shoehorns made from steel grade 11 321, selected for its mechanical properties suitable for bending and embossing. The final surface finish was achieved through powder coating in the RAL 9010 SAJ10G shade. Based on a techno-economic analysis, laser cutting was chosen for manufacturing the semi-finished parts, while final shaping combined bending and stamping of the hanging eye, using specially designed fixtures that were tested on prototypes to ensure process efficiency. The semi-finished parts were produced using a BySprint Fiber 3015 CNC laser cutting centre. Bending was carried out on a CBJ 500 hydraulic press and stamping on a CDM 80 hydraulic press. The economic analysis showed total production costs of 53,173.30 CZK, resulting in a competitive unit price of 212.69 CZK at a 20 % profit margin, thus demonstrating a viable techno-economic solution to the specified production task.
