CNC plastic machining offers precision that injection molding or 3D printing cannot match. Plastic parts are also an excellent alternative to metal components, as they are lightweight and often more cost-effective (See machining plastic vs. metal differences for details). BOYI is capable of producing high-quality CNC plastic parts using over 30 different materials, utilizing 3-axis, 4-axis, and 5-axis CNC machining processes. Our engineering team can easily modify designs during production without the need for creating new tooling.
CNC Plastic Machining Materials
ABS
ABS is a versatile, tough thermoplastic with excellent impact resistance, high machinability, and electrical insulating properties. It is often used in automotive parts, electronics, and consumer goods due to its durability and ease of processing. ABS machining produces a matte finish, but it can also be polished for a glossy appearance depending on machining methods.
Polycarbonate
Polycarbonate (PC)) is a high-strength, transparent plastic that excels in optical clarity and impact resistance, even in cold temperatures. Its excellent durability, combined with resistance to UV light and high temperatures, makes it an ideal material for lenses, protective covers, machine guards, and outdoor or automotive applications.
We offer four grades of machined polycarbonate: Black, Clear, Translucent, and 20% Glass-Filled, to meet a variety of application needs.
PMMA (Acrylic)
PMMA, also known as acrylic or plexiglass, is a clear, lightweight plastic with high optical clarity, making it an excellent alternative to glass. It is resistant to UV light and weathering, making it suitable for outdoor signage, displays, and windows. Acrylic is easy to machine and can be polished to a high-gloss finish, although it may be prone to cracking under heavy stress.
Colors: Clear, tinted, frosted
POM (Acetal)
POM, or acetal, is a high-strength, low-friction plastic with excellent dimensional stability, making it ideal for precision engineering parts such as gears, bearings, and bushings. It has superior wear resistance and low moisture absorption, making it suitable for harsh environments where high performance is required.
CNC Processes: CNC milling, CNC turning
Colors: White, black, natural
Nylon
Nylon is a strong, flexible material with excellent tensile strength, wear resistance, and low friction. It is widely used in high-performance applications such as automotive components, bushings, and gears. Nylon can be easily machined and is available in various grades, including glass-filled versions for enhanced strength.
Colors: Natural, black, gray
Material Grades: Nylon 6, Nylon 66, Glass-filled Nylon, PA12
Polyethylene (PE)
Polyethylene is a cost-effective, low-density thermoplastic known for its flexibility and chemical resistance. It is commonly used in applications such as containers, pipes, and insulation.
HDPE (high-density polyethylene) and LDPE (low-density polyethylene) offer different properties for use in a variety of industries.
Colors: White, natural, black
Material Grades: HDPE, LDPE, UHMW-PE
PEEK
PEEK is a high-performance thermoplastic known for its exceptional strength, chemical resistance, and thermal stability. It is widely used in demanding industries such as aerospace, automotive, and medical applications, where high-temperature performance and wear resistance are critical.
Polypropylene (PP)
Polypropylene is a flexible, impact-resistant plastic with good chemical resistance, low moisture absorption, and electrical insulating properties. It is commonly used in automotive, medical, and consumer goods applications due to its lightweight nature and high resistance to fatigue.
HIPS (High Impact Polystyrene)
HIPS is a rigid, impact-resistant plastic that is commonly used for point-of-purchase displays, packaging, and vacuum forming. It is easy to machine and provides a smooth surface finish. HIPS is also often used as a substrate for applications requiring decorative coatings.
PBT (Polybutylene Terephthalate)
PBT is a crystalline thermoplastic known for its strength, stiffness, and resistance to chemicals and heat. It is commonly used in automotive and electrical applications for components like connectors and housings. PBT can be reinforced with glass fibers to improve its mechanical properties.
PPA (Polyphthalamide)
PPA is a high-performance plastic with exceptional heat resistance, chemical resistance, and mechanical strength. It is used in demanding automotive, electrical, and industrial applications where high-temperature stability and durability are essential.
PAI (Polyamide-imide)
PAI is a high-performance thermoplastic with excellent high-temperature resistance, wear resistance, and mechanical strength. It is used in aerospace, automotive, and industrial applications requiring outstanding performance under extreme conditions.
PET (Polyethylene Terephthalate)
PET is a strong, clear plastic with excellent dimensional stability and resistance to chemicals. It is used in packaging, electrical insulation, and high-performance applications. PET’s strength and clarity make it ideal for consumer goods and medical devices.
PPS (Polyphenylene Sulfide)
PPS is a high-performance plastic known for its chemical resistance, high strength, and thermal stability. It is ideal for applications in automotive, aerospace, and electrical industries where excellent chemical and thermal resistance is required.
Polystyrene
Polystyrene (PS) is a rigid, clear plastic commonly used for prototypes, packaging, and consumer products. It is easy to machine and offers good surface finish characteristics. Polystyrene is also used in vacuum forming and sheet extrusion applications.
PVC (Polyvinyl Chloride)
PVC is a highly versatile, rigid plastic that is resistant to chemicals, abrasion, and environmental factors. It is widely used for pipes, fittings, and industrial components. PVC is easy to machine and offers good electrical insulating properties.
PTFE
PTFE is a high-performance plastic with excellent chemical resistance, low friction, and a broad temperature range. It is commonly used in seals, gaskets, and non-stick coatings, where chemical resistance and low friction are critical.
UPE
UPE is a strong, abrasion-resistant plastic with superior wear resistance and low friction. It is used in heavy-duty applications such as liners, wear parts, and bearings. UPE is particularly effective in environments where there is continuous abrasion.
FR-4
FR-4 is a flame-resistant composite material made of woven fiberglass and epoxy resin, commonly used in the manufacture of printed circuit boards (PCBs). It has excellent electrical insulation properties and is widely used in the electronics industry.
