tolerance group, which is a critical benchmark for high-precision plastic injection molding.
Under TG5, a 100 mm nominal dimension on a non-critical feature allows a deviation of approximately ±0.2 mm to ±0.3 mm, depending on the material (amorphous vs. semi-crystalline). For reference, TG1 would allow ±0.8 mm at the same length. din 16742 - tg5
When applying TG5 under DIN 16742, dimensions are categorized based on how they are formed in the tool: tolerance group, which is a critical benchmark for
