The standard is a critical benchmark for standard injection molding , specifically defining the general tolerances for plastic parts. Widely utilized by German Tier 1 suppliers, this standard ensures engineering rigor by focusing on the relationship between mold-fixed and non-mold-fixed dimensions.

Crystalline materials (like PBT or PA) shrink and warp more than amorphous ones (like ABS or PC), which can push your part out of the TG5 field if not managed Pekago Covering Technology Wall Thickness:

It is much easier to remove more steel from a mold (adding plastic to the part) than it is to add steel back Pekago Covering Technology

Materials are classified by shrinkage rates (e.g.,
