Nylon (PA) Injection Molding
You may be surprised to learn that nylon is a type of plastic which is actually derived from crude oil. While the material is put through an intensive chemical process before being used in the injection moulding process, it has some very useful characteristics:
- Extremely tough
- High melting point
- Able to accommodate significant wear and tear
- Chemical resistance
- Relatively lightweight
Due in the main to its relative strength, nylon is used to produce an array of products such as:
- Packaging
- Plastic fasteners
- Cookware
- Toothbrushes
- Gears
- Plastic bearings
- Bushings
- Components for engines
While many people predominately see nylon as a simple material, as you’ll see above, it is used in a whole range of different products. This is one of the more common materials used in injection moulding.
