Polytetrafluoroethylene (PTFE) is a polymer of tetrafluoroethylene and is known for its special mechanical and chemical properties. Belonging to the family of compounds known as fluoropolymers, PTFE is used in a variety of applications ranging from cookware to industrial parts. PTFE is well-known by its trademarked brand name – Teflon®, which is owned by Chemours.
Two of the most beneficial properties of PTFE is that it is chemical resistant and assures better thermal stability, which makes it a superior choice for applications that require both. PTFE is one of those popular plastic polymers that can be easily machined to any form that you desire. This makes it a popular choice of material for producing parts featuring intricate designs and complex geometries. Although PTFE enables exceptional design flexibility, it is always important to partner with experienced plastic fabrication services to achieve the desired results. At Ehren-Haus, we specialize in customized PTFE/Teflon machining services for industrial applications. Our vast industrial experience coupled with our technical knowledge and manufacturing expertise has helped us build performance-driven PTFE machined parts.
Our focus and commitment to providing quality custom Teflon machining services has earned us several opportunities to work on unique projects, which are usually avoided by regular plastic fabrication shops. Our experts work with clients in all phases of design and manufacturing to assure the quality products.
What is Our Process?
We accept designs for PTFE machined parts in IGS, CAD, and DXF formats. The designs are analyzed and discussed with the client for clarity. Any design changes are suggested in the initial stages. The prototype building begins after seeking their approval.

At Ehren-Haus, we specialize in the following PTFE fabrication services.
This is the most popular PTFE fabrication process undertaken by our experts. In this process, the sheets of PTFE material are heated to a certain temperature and softened. The softened material is poured into a mold, where it then takes the form of the mold. In thermoforming, PTFE sheets can take the form of the mold, without applying any external force.
This is another popular Teflon fabrication process performed by our experts. In this, the PTFE sheet is placed on the mandrel or fixture or mold using vacuum pressure. Generally, the plastic forming technique is employed for creating hollow objects.
CNC plastic machining technique is most suitable for creating parts that demand precision. Over the years, we have performed PTFE machining services for complex parts. Our Teflon machining services enable us to produce intricate Teflon machined parts or PTFE machined parts easily.
Teflon exhibits the following properties, which makes it extremely popular among all plastic polymers available today.
PTFE/Teflon is well-known for its thermal properties. It can withstand temperatures ranging from -200° C to +260° C, which makes it suited for high temperature as well as cryogenic temperatures. The PTFE machined parts can withstand ambient temperatures without sacrificing their form or performance. This material has a high melting point of 327° C.
The PTFE material exhibits immense flexibility at low temperatures, which makes them an ideal choice for industrial components as well as products.
Teflon machined parts are easy to wipe and clean. Being hydrophobic, PTFE thwarts liquid particles that may stick to its surface. Thus, Teflon machined parts are chosen for applications where they may come in contact with water or other liquids.
The Teflon material exhibits excellent electrical properties such as low dielectric constant and high insulation resistance. The dielectric constant of the material is 2.0 and the macromolecules possess a highly symmetric structure.
This material possesses excellent chemical resistance. Although it can resist most chemicals, PTFE cannot withstand alkali metals, organic halogenated compounds such as oxygen difluoride, chlorine trifluoride, and gaseous fluorine at high pressures and temperatures. Owing to its chemical resistance, PTFE is used as coating for parts, surfaces, and components to resist corrosion and rust.
The following are a few reasons for choosing Teflon machined parts.
Teflon possesses low friction, which makes it a popular choice for various sliding applications. Taking advantage of this property, we often use it for machine gears, slide bearings, and plates for our clients.
PTFE can withstand wear and tear in challenging environments, which is why it is used for making hose assemblies and pipes.
PTFE is one of the most popular and most affordable polymers, which makes it a preferred choice for several industrial applications. PTFE fabricated parts can resist aging and embrittlement.
Teflon/PTFE is FDA-approved, which makes it food safe. It can resist staining, which is why it is widely used for creating various applications in food packaging and manufacturing.
