Dimensions affected by moving tool parts, such as sliders, cores, or the parting line. These usually have wider tolerances because they are subject to tool opening/closing variances. 2. Material Behavior
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. din 16742 - tg5
Parts where functional fit is important but doesn't require extreme sub-millimeter precision. Dimensions affected by moving tool parts, such as
Plastics are categorized by their . Crystalline materials (like POM or PA) tend to shrink and warp more than amorphous materials (like ABS or PC), which can move a part out of a specific TG rating if not managed. 3. Production Environment Material Behavior Understanding DIN 16742 - TG5 is
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
