Din: 16742 - Tg5 ((top))
Choosing the right tolerance group is critical because plastic behavior differs significantly from metal. Plastics are subject to high thermal expansion, moisture absorption, and shrinkage—factors that DIN 16742 addresses through its system of nine tolerance groups (TG1–TG9). What is Tolerance Group 5 (TG5)?
Dimensions determined by a single part of the mold tool. These are typically more accurate. din 16742 - tg5
Parts where functional fit is important but doesn't require extreme sub-millimeter precision. Choosing the right tolerance group is critical because
For many manufacturers, TG5 is the default starting point. If a design requires tighter tolerances (TG4 or higher), production costs usually increase due to stricter process monitoring and potential tool modifications. Key Factors in DIN 16742 Dimensions determined by a single part of the mold tool
Understanding DIN 16742 - TG5 is the central German engineering standard for determining tolerances in plastic molded parts. Within this framework, TG5 (Tolerance Group 5) represents the "baseline" or "standard" precision level for modern injection molding.
