In the world of plastic injection moulding, achieving dimensional precision is a complex challenge. The properties of plastics, including their tendency to shrink, warp, and react to environmental conditions, mean that the tight tolerance standards used for metal parts are often unsuitable. For decades, the German standard DIN 16901 was the benchmark. However, after nearly 40 years, it was officially withdrawn in 2009. Its successor, , emerged in 2013, introducing a modern, process-oriented approach to defining manufacturing tolerances for plastic moulded parts. At the heart of this new system are the Tolerance Groups (TG) , with TG5 representing one of the most critical and widely applied classes for standard injection moulding. This article provides a comprehensive guide to DIN 16742-TG5, exploring its definition, application, and significance for engineers, designers, and manufacturers. These have tighter tolerances because they are unaffected
: Features formed by a single mold component (e.g., a cavity insert). These feature tighter tolerances because tool movements do not affect them.
The "TG5" likely refers to a specific test method within this standard.
