CNC Machining in PTFE/Teflon
PTFE-Teflon CNC machining is widely applied for common use in different industries through the manufacturing of Teflon machined parts or components.
What Is PTFE Plastic or Teflon?
PTFE, or polytetrafluoroethylene, is a versatile engineering plastic and synthetic fluoropolymer of tetrafluoroethylene completely composed of carbon and fluorine atoms. And PTFE is usually well-known by its trade name, Teflon. Teflon is a fluorocarbon solid that has higher temperature resistance than all common engineering plastics. Depending on its fluoropolymer chemical makeup, it’s exceptional corrosion-resistant and insoluble in water or aqueous substances.
PTFE has been used in broad applications across various fields. The most notable usage of PTFE is as cooking utensils like the nonstick coating of pots. And it is often used in containers and pipes for the prevention of active and corrosive chemicals. Due to its excellent low coefficient of friction, it is an ideal material as a lubricant to help lower wear, friction, and machine energy consumption. Moreover, using Teflon as a graft material is another important application in the medical field.
CNC machining in PTFE is readily machinable thanks to its low strength, relative softness, and great thermal stability.
Nonstick & pipe coating, automotive lubricant, medical implants, electrical component insulation.
It is determined by the desired effect and the titanium used. A tolerance of ±0.010” (±0.25 mm) is available at Runsom.
Hydrophobic, non-toxic, high resistant to high and low temperature and chemicals, low friction coefficient.
It is mostly decided by the available machine and part geometry. A minimum wall thickness of ±0.03” (±0.8 mm) is available at Runsom.
As fast as 3 days, but it will be finally determined by part complexity and order quantity.

Teflon/PTFE CNC Machining Parts Applications
What set PTFE apart from most engineering plastics are its low friction coefficient, high melting point, and chemical inertness. All of those exceptional performances make it perfect for kitchen cookware and extensive use in the petrochemical, medical, electrical components, and food and beverage fields.
It is a popular material for household items like non-stick coating in cookware and more.
In computer and aerospace industries, PTFE plastic is usually used for laying wires like coaxial cables and connecting wires.
For microwave applications, CNC machined Teflon is greatly suitable for connector components at high RF and PCB insulation due to its insulation to electricity.
PTFE material is a cost-effective substitute for polyethylene depending on its high-temperature resistance.
Teflon can be found in many industrial occasions that need low friction such as sliding washers, plates, seals, bushings, bearings, etc.
It is commonly used as the lining of expansion joints, industrial pipelines, and hose assemblies as a result of its chemical inertness and high melting point.
It is a proper material in the production of glass fiber composites and carbon fiber composites.
Machined PTFE can be used as a lubricant for musical instrument products, such as valve lubricating oil.
Our Strengths in CNC PTFE/Teflon Machining Services
- Low coefficient of friction
- Corrosive and electrical resistance
- Maintaining valid under a wide range of temperatures
The disadvantages of PTFE are as follows:
- Relatively high price
- Not easy to mass produce and be welded
- The mechanical strength will be invalid at 326°C
PTFE is highly heat resistant and resistant to friction with solids, which allows PTFE to be used as an integral part of gears, side plates, bearings, and washers. It is also used to make pipes and containers because it is corrosion-resistant and non-reactive. PTFE also has good electrical insulation properties and is used to insulate cables and connector assemblies. This makes it an ideal material for printed circuit boards, hookup wires, and coaxial cables.
