CNC plastic parts are parts that are made using a CNC (computer numerical control) machine. These machines are used to fabricate a wide range of parts and products, including those made from plastic. In the manufacturing process, a CNC machine uses computer-controlled cutting tools to shape and form the plastic material into the desired shape. The process is highly precise and can produce parts with a high degree of accuracy and repeatability. CNC plastic parts are used in a variety of applications, including in the automotive, aerospace, and medical industries, among others.
