Understanding DIN 16742 TG5: The Standard for Precision Plastic Molding Tolerances
Within this standard, represents a high-precision category suitable for parts requiring tight, but still economically viable, dimensional accuracy. What is DIN 16742? din 16742 - tg5
: Tighter groups like TG5 are easier to achieve with amorphous resins (e.g., ABS, PC) that have low, predictable shrinkage than with semi-crystalline materials (e.g., PA66, POM). Dimension Type : DIN 16742 distinguishes between Tool-specific (W) Non-tool-specific (NW) dimensions: Tool-specific (W) Understanding DIN 16742 TG5: The Standard for Precision
The standard distinguishes between (those directly determined by the mold's geometry) and non-tool-bound dimensions (those influenced by external factors). It also classifies achievable manufacturing precision into nine tolerance groups, ranging from TG1 (extremely tight) to TG9 (very wide). The choice depends on material, part geometry, and production process capability. is the central German standard for determining plastic
is the central German standard for determining plastic part tolerances, and TG5 (Tolerance Group 5) is frequently cited as the baseline for "Standard Injection Molding". Understanding TG5 (Tolerance Group 5)
Dimensions affected by moving parts (like across a parting line or between a slider and a core). These require wider tolerances Super-Ingenuity Material Choice:
: When designing for TG5, engineers must account for the specific resin tolerance
