DIN 16742 replaced the older DIN 16901 in 2013 to provide a more rigorous framework for injection molding Super-Ingenuity . It isn't just a list of numbers; it's a system that links material properties mold design manufacturing accuracy Super-Ingenuity 2. Decoding TG5 (Tolerance Group 5)
Draft angles: 1.0° per side unless noted All dimensions in mm; burrs max. 0.2 mm din 16742 - tg5
: Dimensions formed by a single part of the mold (e.g., within one cavity half). These typically have tighter tolerances. DIN 16742 replaced the older DIN 16901 in
: Engineers are advised by firms like Pekago Covering Technology to design parts at the "middle" of the tolerance field to allow for material fluctuations. din 16742 - tg5
The success of meeting TG5 is heavily dependent on the material's shrinkage characteristics.
