: Dimensions affected by moving mould parts (e.g., across the parting line, sliders, or lifters). These require larger tolerances to account for mechanical play in the mould. Standard Acceptance Conditions
sits in the middle, representing normal industrial precision for injection molding without special tooling or process controls. It is the most commonly specified tolerance grade for functional plastic parts. din 16742 - tg5
To reach the tight requirements of TG5, engineers often use a "Steel Off" : Dimensions affected by moving mould parts (e
TG5 assumes dimensional stability at 23°C / 50% RH. If your part operates at 80°C in PA66, the tolerance must be loosened by 25% due to creep—or switch to glass-filled material. It is the most commonly specified tolerance grade
DIN 16742 TG5 refers to a specific "Tolerance Group" (TG) within the German standard for injection-molded plastic part tolerances. While is the most common standard for general industrial parts,
