Thermoforming High Performance Films Like Teflon™ Film
We are experts in converting ultra thin (typical starting gauge range .003” – .060”), flat, high-performance thermoplastic films (like Teflon™ Film) into intricate custom three-dimensional shapes by utilizing the manufacturing process of thermoforming.
Below is a partial list high-performance materials (thin films) that we are experts in Thermoforming:
- Teflon™ FEP Film
- Teflon™ PFA Film
- Tefzel™ ETFE Film
- Vestakeep® PEEK Film
- Ultem® PEI Film
- Aclar® PCTFE Film
- Halar® ECTFE Film

Thermoforming has some unique advantages over other methods of processing plastics, such as injection molding:
- Parts are capable of having ultra thin walls (.001″) that can fit into tight spaces
- Precision tolerances
- +/- .002” for Thermoforming
- +/- .005” for trimming
- Rapid turn around time for proof of concept prototypes
- Optimal process for testing multiple materials during the prototype stage
- Low cost for prototype, pre-production and production tooling
- No weld lines
- Less susceptible to pinholes
Examples of End Use Applications
- Dielectric Properties / Insulation
Implantable medical device components for battery and capacitor insulation and chemical resistance.
An excellent alternative to Parylene Coatings.
- Temperature Resistance
Perfect for applications that require high maximum use temperatures.
An excellent alternative or replacement for polyimide tapes, which are labor intensive.
- Chemical Resistance
For applications that require a material that can stand up to the harshest environments.
For applications that require a non-contamination / non-reactive material.
For applications that require a non-stick or non-wettable material
Processes and Value Added Manufacturing
Our thermoforming manufacturing processes are extremely flexible and allow for a variety of application sizes including prototypes, pre-production, small production and large production annual blanket orders. All thermoforming processes are highly traceable, and Certificates of Compliance are available upon request.
Using a variety of innovative technologies, we are able to use precise manufacturing techniques to produce extremely complex custom components. Unique features that can be added to parts include:
- Multi plane trimming
