Quality assessment of PEEK plastic components for medical devices

Many shops offer plastic turning services and turn precision parts; however, it is far less common to find a shop that has expertise in both. Controlled Fluidics has extensive experience in plastic turning precision parts. With our seven-axis lathes, we are able to produce close tolerance, precision finish components to print complete from the machine.

We don’t just turn regular plastic parts. We turn the parts that are considered difficult to machine and have to be spec perfect.


Finish and Tolerances

Pushing the limits of technology, we produce superior finishes and extremely close tolerances. Finish and tolerances are often intertwined. We can produce lathe components with tolerances to +/-.0002 given an appropriate material choice and part size. Finishes below 32 microinches are typical with finishes of less than two microinches possible. Need them clear? We do that, too.

Challenging Configurations

Rings held to close tolerance, parts with thin walls, and unstable materials are familiar challenges in CNC plastic turning. We manage these difficult configurations with proprietary stress relieving and specialized tooling. Polyolefin lathe work is one of our specialties, allowing us to hold close tolerances with a superior, burr-free finish.

See-Through Plastic Turning Applications

Many medical devices require clear turn components when machining amorphous plastics. Using cutting-edge techniques, we can produce lathe parts for optical applications directly from the machine tool. Our plastic parts are always created with low stress and with no post machining polishing required. Our efficiency is the key to offering our customers more competitive pricing.

Plastic Lathe Micromachining

Controlled Fluidics specializes in small/micromachining. Typical applications are in the cable industry, producing high performance turned insulators in Teflon and Ultem. Tolerances are held close, normally +/- .0005 or better. Our customers can count on us for post annealed Teflon lathe parts. We adapt our machining for turned components that require post anneal for stress relief.


Do you need lathe parts to test your design, but 3D printed components are too inaccurate? Controlled Fluidics can help. We build production-quality parts in small batches, allowing you to try before you commit. Customers benefit from the flexibility of getting additional clear components to help with process visualization.

Plastic Turning Material Knowledge

With over more than twenty years of experience, we have turned nearly every type of plastic available in stock form. We have produced thousands of lathe plastic parts in a multitude of configurations. This deep experience is applied to the customer’s designs, providing support for material selection and manufacturability.

The team at Controlled Fluidics is ready to manufacture the best possible lathe parts for you.
