Engineering plastics can withstand high levels of mechanical stress, and that’s why they are used in many mechanical applications under harsh conditions. Certain engineering plastics offer high strength, heat, and chemical resistance properties, making them suitable for manufacturing functional components. These plastics can be machined to precise specifications with a Plastic CNC machining process or 3D printed to create functional parts that complement metal components in assemblies. Some of the most commonly used machining plastics are:

ABS
ABS is a thermoplastic polymer with three monomers: acrylonitrile, butadiene, and styrene. It offers a balance of properties, including good impact resistance, rigidity, heat resistance, and dimensional stability. It exhibits excellent processability. Hence, it is used to prototype parts before injection molding.
