Din 16742 - Tg5 Fixed 💯

Parts where functional fit is important but doesn't require extreme sub-millimeter precision.

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

The standard doesn't just provide a table of numbers; it calculates tolerances based on several variables: 1. Mold-Fixed vs. Non-Mold-Fixed Dimensions din 16742 - tg5

DIN 16742 requires that dimensions be measured under specific , usually 16 to 24 hours after molding at a standard atmosphere of 23°C and 50% humidity.

Dimensions determined by a single part of the mold tool. These are typically more accurate. Parts where functional fit is important but doesn't

Products that need a clean aesthetic and reliable assembly.

Cases and housings where dimensional stability is necessary for snap-fits or screw bosses. Key Factors in DIN 16742 The standard doesn't

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.
