Assuming you mean the German standard DIN 16742 (TG5) and want its proper name and main feature:
: Interestingly, high-quality vacuum casting can also achieve TG5 levels of accuracy, making it a viable bridge between prototyping and mass production. din 16742 - tg5
Are you looking to apply these tolerances to a or a particular manufacturing process like injection moulding? Vacuum Casting | FACTUREE – The Online Manufacturer Assuming you mean the German standard DIN 16742
In the context of the standard’s tables, TG5 specifies a permissible deviation that is significantly tighter than what might be acceptable for a disposable item, yet achievable without exotic tooling or specialized environment controls. For example, on a nominal dimension of 100mm, the tolerance range in TG5 would be narrow enough to ensure good fitment with mating parts, but wide enough to account for the natural variability of the injection molding process. For example, on a nominal dimension of 100mm,
. Thinner walls (as low as 0.7 mm for PBT) cool faster and can help maintain dimensional stability 4. Pro Tip: The "Steel Off" Strategy When aiming for TG5 accuracy on critical fitting features: Design it "Small":
