- Machinability
While not as fine as acetal, the machinability of un-modified Nylon 12 is good. Glass-filled grades will require the use of tipped tooling. As with all plastic materials, experience has shown that extra care must be taken with larger diameters, especially in the colder months when plastic materials lose some of their toughness and so have less resistance to machining stresses. So it's important that these materials are not machined while in a chilled condition.
