Machined Polysulfone
June 17, 2009
This part is made out of Polysulfone. Polysulfone is known for being tough, wear resiting, and high temperature stability. It is also a dielectric material that can be used in capacitors. Dielectric means that it will not transmit electricity.
This part is milled in the milling department here at East Coast Precision. It is approximately 1.5 inches square. It features a milled out body, some threaded holes and a polished top. Due to the geometry, the part is actually able to spring a little bit.
Ultem Machining at East Coast MFG
June 15, 2009
This a sample of some turned Ultem we have been working on at East Coast Precision Manufacturing. Ultem is known for its resistance to chemicals, solvents, and heat. It is often used for instrumentation and reusable medical components. More information about Ultem.
On this part, each end is bored to a very tightly toleranced TIR (total indicated runout). The outside diameter is nicely contoured as well.
East Coast’s machining processes allow for thin walled parts like this to be manufactured very little stress. This makes for a more durable and longer lasting part.
Turned Delrin-AF
June 5, 2009
This part is made out a Delrin-AF, a blend of delrin and teflon. The most striking feature is the helical slot that is machined on the OD. The slot width is tightly toleranced at ±.00025. It also features an OD groove and counterbores on each end. Our machining process allows us to produce these parts with minimal to no burrs so secondary operations are not needed in most cases.
