Meaning
Precision tolerance grade defines the specific geometric accuracy required for technical injection moulded parts made from engineering polymers. Selecting din 16742 tg6 places a moulder within a strict band of dimensional variation typically used for tight fits.
Tolerance Application
Engineering drawings specify the band to ensure that mating components align perfectly across different production batches. Achieving din 16742 tg6 demands accurate control over melt temperature and packing pressure to stabilize the final dimensions. Higher shrinkage materials such as polypropylene require closer oversight to meet this mark.
Mould Accuracy
High quality tooling built to fine machining limits is a prerequisite for consistency at this level. When parts drift from din 16742 tg6 requirements, the cause often lies in cooling channel variance or inconsistent gate placement. This grade represents a narrow window of acceptable error that excludes most low-cost commodity production methods.
Manufacturing Constraint
Process stability serves as the primary driver for holding dimensions within this limit during high-volume production. Moulders monitor cavity pressures in real time to prevent the fluctuations that push measurements out of the din 16742 tg6 range. Regular inspection confirms that the tool has not worn enough to affect fit.
Failure to hold the limit results in scrap or assembly rework.
