Introduction
Plastic is a common material used in many applications, including CNC machining. CNC machining refers to the process of using a computer numerical control (CNC) machine to cut, grind, and shape plastic materials to precise specifications. There are various types of plastic used for CNC machining, each with unique properties and applications. This article will explore the different types of plastic commonly used in CNC machining.
Types of Plastic
1. Polyethylene (PE)
Polyethylene is a versatile plastic material that is commonly used in CNC machining. It is a tough, durable material that can withstand high-impact forces. It is commonly used in parts that require repeated use and are subjected to wear and tear, such as fasteners, washers, and bushings.
2. Polypropylene (PP)
Polypropylene is another common plastic material used in CNC machining. It is a strong, lightweight material that is resistant to abrasion and chemicals. It is commonly used in parts that require high levels of durability and cleanliness, such as food packaging, medical devices, and automotive components.
3. Polystyrene (PS)
Polystyrene is a versatile plastic material that is commonly used in CNC machining. It is a cheap and easy-to-work-with material that can be shaped and machined easily. It is commonly used in small parts and components that require a smooth finish,cnc machining plastic such as packaging materials, labels, and moldings.
4. Polyurethane (PU)
Polyurethane is a strong, resilient plastic material that is commonly used in CNC machining. It can be molded and shaped into complex forms and textures, making it suitable for use in high-end products and components that require a unique appearance and feel. It is commonly used in footwear, automotive interiors, and sports equipment.
5. Thermoplastics
Thermoplastics are a group of plastics that can be shaped and reshaped multiple times. They are commonly used in CNC machining because they can be easily cut, drilled, and machined into precise shapes and sizes. Some common thermoplastics include acrylonitrile butadiene styrene (ABS), polycarbonate (PC), and polyvinyl chloride (PVC).
6. Thermosetting plastics
Thermosetting plastics cannot be reshaped or reused after they are initially shaped and cured. They are commonly used in CNC machining for their high strength and durability. Some common thermosetting plastics include epoxy resin, nylon, and fiberglass reinforced plastics (GFRP).
Conclusion
Plastic is a versatile material that can be shaped and machined into various forms and sizes using CNC machines. There are various types of plastic used for CNC machining, each with unique properties and applications. Understanding the different types of plastic available and their properties will help you choose the best material for your project.
