Achieving Optical Perfection: A Deep Dive into DIN 16742 – TG5

In the world of injection-molded plastic components, a frequent source of friction between designers and manufacturers is surface quality. Designers demand "perfect" parts, while production managers speak in microns and shrinkage rates. The German standard DIN 16742 bridges this gap. At its peak sits TG5—the highest tolerance grade for surface finish and geometry.

5. Draft Angle Recommendations for TG5

While draft angles are not strictly a tolerance, they are critical for achieving TG5 reliably. din 16742 - tg5

Status Update: Note that DIN 16742 was officially withdrawn and superseded by the international standard DIN ISO 20457:2020-03. Comparison of Tolerance Groups At its peak sits TG5 —the highest tolerance

Tolerance Grades: While TG5 is the standard for injection molding, other grades like TG7 are used for specialized processes such as Structural Foam Moulding (SFM).

, TG5 is typically applied to parts where dimensional accuracy is paramount, but absolute "tight" tolerances (like TG1 or TG2) are not functionally required. Application
