Din 16742 - Tg5 [4K 2026]

When citing on a drawing, you are telling the manufacturer that you require a standard of "Accurate Production". To avoid ambiguity, always clearly mark your Acceptance Dimensions and consult with your molder to confirm that your chosen material's shrinkage rate aligns with TG5 capabilities. DIN 16742 - 2013-10

| Feature depth (mm) | Recommended draft (per side) | |--------------------|-------------------------------| | 0 – 10 | 0.5° – 1.0° | | 10 – 30 | 1.0° – 1.5° | | 30 – 100 | 1.5° – 2.0° | | Over 100 | 2.0°+ | din 16742 - tg5

: Achieving TG5 requires more intensive process monitoring and higher-quality tooling, which generally increases production costs compared to TG6. www.makrolar.eu Factors Affecting TG5 Compliance When citing on a drawing, you are telling

: Achieving TG5 often requires materials with lower shrinkage rates (e.g., amorphous resins like PC or ABS) rather than high-shrinkage semi-crystalline materials. Key Tolerance Concepts When a part has justified high dimensional stability

All tolerances are symmetrical ((\pm)). A practical minimum tolerance of is generally applied regardless of what the table might yield for very small nominal sizes.

When a part has justified high dimensional stability requirements beyond what general tolerances can provide, the designer may assign (i.e., a specific tolerance value attached to a particular dimension in the drawing). However, for economic reasons, the number of directly toleranced dimensions per moulded part should be kept as low as possible.
