Materials For Plastic Machining
We provide high-precision Plastic CNC Machining services tailored for industries ranging from medical to aerospace. By leveraging advanced milling and turning techniques, we transform raw plastic polymers into complex, high-tolerance components that meet your exact specifications.
ABS
Acrylonitrile Butadiene Styrene (ABS) is one of the most widely used thermoplastics in CNC machining. Known for its balance of impact resistance, structural integrity, and affordability, it is a go-to material for both rapid prototyping and end-use production parts.
ABS Applications in CNC Machining:
Prototyping: Functional models for consumer electronics.
Automotive: Dashboards, trim pieces, and protective covers.
Enclosures: Custom housings for electrical components.
- High Machinability
- Impact Resistance
- Cost-Effective
Nylon
Nylon (Polyamide) is one of the most widely used engineering plastics in CNC machining because of its exceptional toughness, wear resistance, and versatility. It is valued across industries for producing durable, functional components that can withstand mechanical stress and friction.
Common Grades Nylon in Machining:
Nylon 6/6: The standard grade. It’s strong, easy to machine, and has a high melting point.
MDS-Filled Nylon: Infused with molybdenum disulfide (a dry lubricant). It’s usually dark grey or black and is even more slippery than standard nylon.
Glass-Filled Nylon: Reinforced with glass fibers to increase stiffness and reduce thermal expansion, though it is more abrasive on cutting tools.
- Good Machinability
- Low Friction & Self-Lubrication
POM
POM (Polyoxymethylene) is a high‑performance engineering thermoplastic prized for its strength, stiffness, and excellent machinability. It is one of the most popular plastics for CNC machining when precision and durability are required.
POM Applications in CNC Machining:
Mechanical Components: Gears, bushings, bearings, rollers, and pulleys.
Automotive: Fuel system parts, clips, and fasteners.
Industrial Machinery: Precision components in conveyor systems and equipment.
Consumer Products: Durable handles, zippers, and appliance parts.
Electrical Applications: Insulating components due to its dielectric properties.
- Ease of Machining
- Dimensional Stability
- High Rigidity
Polytetrafluoroethylene (PTFE)
Polytetrafluoroethylene (PTFE) is a high-performance fluoropolymer defined by its extreme slipperiness and near-total chemical immunity. It is the material of choice for environments involving aggressive chemicals or where components must slide with minimal resistance.
PTFE Applications in CNC Machining:
Seals & Gaskets: Resistant to chemicals and heat, ensuring reliable sealing.
Bearings & Bushings: Low friction surfaces for smooth movement.
Electrical Insulators: Components in high‑voltage or sensitive electronics.
Medical & Food Processing: Non‑stick, chemically inert parts safe for contact applications.
Industrial Equipment: Linings, spacers, and parts exposed to corrosive environments.
- Extreme Chemical Resistance
- High Temperature Performance
- Electrical Safety
Polypropylene (PP)
Polypropylene (PP) is a lightweight, chemically resistant thermoplastic that can be precisely shaped using CNC machining, making it ideal for durable parts in industries like automotive, medical, and consumer goods.
Key Characteristics of PP in Machining
Extreme Chemical Immunity: It is virtually inert, resisting most acids, bases, and organic solvents, making it a staple for chemical handling.
Low Density & Buoyancy: As one of the lightest thermoplastics, it is ideal for weight-reduction and applications that must float.
Zero Moisture Absorption: Unlike Nylon, it does not swell in humid environments, ensuring it remains stable when submerged.
Impact Toughness: It possesses high elasticity and ductility, allowing it to absorb significant impact without cracking or shattering.
- Easy Welding & Machining
- Lightweight
- Highly Cost-Effective
HDPE (High-Density Polyethylene)
HDPE is a strong, lightweight thermoplastic known for its high impact resistance, chemical resistance, and low moisture absorption. It is easy to machine with CNC tools due to its softness and toughness, producing durable parts without cracking.
Key Characteristics of CNC Machining HDPE
Exceptional Chip Formation: Because it is a soft thermoplastic, HDPE allows for high feed rates. It cuts cleanly and quickly, which reduces wear and tear on your CNC bits.
Zero Water Retention: Unlike many polymers that swell in humid conditions, HDPE is hydrophobic. This ensures that your machined parts maintain their tight tolerances and dimensions regardless of the environment.
- Low-Friction Surface: The material has a naturally low coefficient of friction. In many cases, this eliminates the need for external lubricants during both the machining process and the part’s end-use life.
- High Chemical Stability
- Excellent Machinability
- FDA Food-Grade Certified
Ultra-High Molecular Weight Polyethylene (UHMWPE)
Ultra-High Molecular Weight Polyethylene (UHMWPE) is a high-performance engineering plastic valued for its extreme durability. Its exceptionally long molecular chains provide significantly higher impact strength and wear resistance than standard polyethylene.
Key Characteristics of CNC Machining HDPE
Exceptional Chip Formation: Because it is a soft thermoplastic, HDPE allows for high feed rates. It cuts cleanly and quickly, which reduces wear and tear on your CNC bits.
Zero Water Retention: Unlike many polymers that swell in humid conditions, HDPE is hydrophobic. This ensures that your machined parts maintain their tight tolerances and dimensions regardless of the environment.
- Low-Friction Surface: The material has a naturally low coefficient of friction. In many cases, this eliminates the need for external lubricants during both the machining process and the part’s end-use life.
