Under the DIN 16742 standard, Tolerance Group 5 (TG5) represents a precision-oriented classification for plastic molded parts. It is typically applied to dimensions where standard production tolerances (like TG6) are insufficient but ultra-high precision (like TG3 or TG4) would be cost-prohibitive. Key Characteristics of TG5
: It is often specified for "hard" plastic components or multi-component parts where a more accurate fit is needed (e.g., snap-fits or bearing housings). Cost vs. Accuracy
Final recommendation: Always add a note to your drawing: "All dimensions per DIN 16742 - TG5 unless otherwise noted. Material group B (POM). Shrinkage pre-settlement required." This single line has saved countless tooling reworks.
Implementing DIN 16742 - TG5 involves both manufacturers of tool holders and end-users. For manufacturers, it means adhering to strict design and production guidelines. For end-users, it involves selecting tool holders that are certified to meet the standard and understanding how to properly use and maintain them.
Thin walls are the nemesis of plastic molding. For a 2 mm nominal wall thickness, TG5 allows a deviation of ±0.07 mm. This is critical for fluid flow channels or electrical insulation barriers.
—such as stiffness and shrinkage—rather than just listing specific materials, allowing for more accurate predictions across various resins. Deep Mould Breaking Down TG5 (Tolerance Group 5) Within DIN 16742, "TG" stands for Tolerance Group
The production of plastic parts requires a delicate balance between material behavior and mechanical precision. Unlike metals, plastics undergo significant shrinkage and environmental expansion, making standardized tolerances essential. The DIN 16742 standard serves as the primary benchmark for these requirements, with Tolerance Group 5 (TG5) representing a critical mid-to-high precision tier for industrial applications.
