A wide range of plastics can be effectively machined using CNC technology. These materials can be broadly categorized into two main groups:
Thermoplastics:
- Acrylic (PMMA): Known for its clarity, durability, and ease of machining. Widely used in signage, displays, and enclosures.
- ABS (Acrylonitrile Butadiene Styrene):A strong and impact-resistant material, commonly used in prototyping, automotive parts, and consumer electronics.
- Nylon (PA):Offers excellent wear resistance and strength, making it suitable for gears, bearings, and other high-stress applications.
- Polycarbonate (PC):High impact strength, good optical clarity, and high heat resistance, often used in safety applications and electronics.
- Polyethylene (PE):Available in various densities (HDPE, LDPE), known for its chemical resistance and good wear properties. Used in many applications, from packaging to industrial parts.
- Polypropylene (PP):Lightweight, chemical-resistant, and widely used in automotive, medical, and packaging industries.
- Delrin (POM):High strength, stiffness, and dimensional stability, making it suitable for gears, bushings, and other precision parts.
Thermosets:
- Phenolics:Known for their high strength, heat resistance, and electrical insulation properties. Used in electrical components, adhesives, and composites.
- Epoxies:Primarily used as adhesives and casting materials, offering excellent bonding strength and chemical resistance.
