CNC or Computer Numerical Control cutting is a way to make precise parts from a block of material by using machine tools that are managed by a computer. It is widely used to make metal and plastic parts for various businesses and industries around the globe.
Benefits like scalability, repeatability, high performance, and material versatility are some of the benefits associated with CNC machining plastics. Benefits like these make CNC machining plastics an ideal and cost-effective choice for producing custom and complex parts.
Types of Plastics for CNC Machining
Acrylonitrile Butadiene Styrene
Known for its strength, toughness, and impact resistance Acrylonitrile Butadiene Styrene (ABS) is a popular plastic that is widely used in consumer goods, automotive components, and electronic housing.
Polycarbonate is a strong, transparent plastic material with excellent impact resistance, dimensional stability, and optical clarity. It is often used in high-strength and transparency applications, such as protective equipment and lighting components.
Like other types, Polyethylene is also widely used in the packing, piping, and container industry because of its chemically resistant molecular structure.
Polypropylene is another widely-used plastic found in various industries, such as manufacturing, medicine, and automotive. Its popularity stems from its chemical resistance, flexibility, and lightweight nature, making it a versatile choice for numerous applications.
Due to its remarkable properties, such as non-stickiness, chemical resistance, and thermal stability, polytetrafluoroethylene, or PTFE, finds extensive use in a variety of applications. These include electrical insulation, cookware, and sealing components.
Acrylic is a material capable of enduring harsh weather conditions, boasting exceptional optical clarity, and remaining unaffected by ultraviolet light. Also known as polymethyl methacrylate or PMMA, this versatile material is commonly used in creating lighting fixtures, display cases, and signage.
Because it is a durable material that is also lightweight and impervious to wear, nylon is an excellent choice for applications that experience high levels of wear, such as gears, bearings, and other similar mechanisms.
