Cast Nylon 6. The method of production of this polyamide (i.e. the polymerisation of the caprolactam directly in the mould) allows the production of stock shapes in larger than normal dimensions, such as big rings or very thick sheets. The general features are similar to those of Nylon 66.6, which means that it is stiffer and more brittle than extruded Nylon.
It can be precision machined for intricate components with tight tolerances and is one of the most commonly used engineering plastics for mechanical applications such as:
In the building of parts for construction machines, excavators and earthmovers it is used for:
