Cast Nylon (PA6G) Engineering PlasticCast Nylon (PA6G)

Heavy Duty Engineering Plastic for many applications

A high-quality general-purpose wear resistant engineering plastic material: the chemical name is polyamide.

It is available in a range of grades and forms to suit many applications. The casting process allows the production of larger material sections virtually free from residual stress. It may also be cast into customer shapes that reduce material waste and machining time.


While not as fine as acetal, the machinability of unmodified nylon is very 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. It’s therefore important to ensure that these materials are not machined while in a chilled condition. Full machining instructions are available on request.

Chemical Resistance

Nylon 6G is highly resistant to: hydrocarbons, alkalis, fats, oils, fuels, ethers, esters and ketones. But it is not resistant to: halogens, mineral acids and certain organic acids, oxidising agents.
