Plastic CNC machining is a subtractive manufacturing process that uses computer-controlled machines to precisely cut, mill, or drill parts from solid plastic blocks or sheets. Known for its versatility, this method is ideal for prototyping and producing lightweight, corrosion-resistant, and cost-effective components. Common thermoplastics and engineering plastics used include ABS, PMMA (acrylic), PEEK, Nylon, Polycarbonate, and PTFE (Teflon), each selected for specific properties such as impact resistance, thermal stability, or electrical insulation.
