- Machinability
The machinability of un-modified acetal is excellent. Good chip forming leads to fine surface finishes. 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. It's therefore important that these materials are not machined while in a chilled condition.
