Machined Teflon / PTFE Manifold

Wednesday, August 12th, 2009

Here is a PTFE manifold we recently machined on one of our mills.  We have developed techniques that allow us to mill Teflon in such a way that burrs are either minimized or eliminated, thus saving part deburring time.  This customer has East Coast do some light assembly work for them as well.  We install the push to connect fitting you see in the first picture.

Teflon (PTFE) is often selected for manifolds for its inert qualities.  Many chemicals do not affect PTFE.

Round Acrylic Manifold

Sometimes it is necessary to utilize multiple machines to effectively produce a part for our customers. This is an example of that. This manifold is machined from acrylic. A turning center (lathe) is used to turn the outside diameter and round features that are concentric to the center of the part. A vertical machining center (mill) is used to complete the rest of the features. On this part, we can see some port work, deep hole milling, and thread milling.

The manifold is also vapor polished for a nice finish. Acrylic vapor polishes quite well but if you need “optical” clarity, polycarbonate would be the way to go.

Milled and Vapor Polished Acrylic Manifold

Monday, June 8th, 2009

Take a look at this acrylic manifold we made for one of our customers. It features four ports connected to a main track. Each port features thread-milled threads.

This part also showcases our vapor polishing process. Not only can we polish the exterior of a part, we can polish interior features that would not normally be able to be polished otherwise.
