G10, FR4, and Fiberglass Machining at East Coast MFG

Wednesday, October 7th, 2009

At East Coast Precision Manufacturing, we not only provide our customers with machined plastic but also other composites.  This is an example of G10 machining.  Some engineers may recognize it as FR-4 but we often refer to it as “fiberglass” here at the shop.  It is a laminated composite held together by an epoxy binder.  It is mainly used in circuit board applications but is also structurally superior to many other materials and finds its way into applications that can take advantage of that.  For some, it is difficult to  machine.  It is very abrasive to tooling, easy to burn, and may de-laminate if the machinist is not experienced in cutting it.  Here at East Coast, we do an excellent job of cutting it due to our time proven methods.  Send us an RFQ, we’d love to work with you.

PTFE (teflon) Machining at East Coast MFG

Friday, June 19th, 2009

Take a look at an example of some PTFE (teflon) turning we do at East Coast Precision Manufacturing. The part you see here is thin walled. It features a OD grooving with a notched feature on one end.

PTFE is often used in the electrical and chemical industries. It is very chemical resitant, stable, and a good insulator.

Teflon machining is one of our core competencies here at East Coast Precision. We have been working with it for a long time and look foward to quoting on your teflon work today!

Ultem Machining at East Coast MFG

Monday, June 15th, 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 Acrylic Video

Thursday, June 11th, 2009

Here is a video of East Coast’s

This is the machining of the part we first featured on the blog a week or so ago. The process for other materials is very similar. We chose acrylic because the chip we produced was easy to blow off with a blast of air. Other materials would require cutting fluids and would have made it difficult to record and see clearly. Hope you enjoy.

UPDATE: It has come to my attention that the sound track to the video was quite obnoxious. Problem fixed. Apparently, youtube offers stock music for videos you upload. Pretty Cool.

Turned Acrylic Example

Monday, June 1st, 2009

This is an example of some of the Acrylic work we can do in our lathe department.

09-06-01-turned-acrylic2

This part has a few different features. The front face has a knife edge where it blends with the inside diameter. It also has a 3 barbs machined on the outside diameter. There is also a groove and contouring on the rest of the OD.

The inside diameter is drilled thru and features a counterbore on the knife edge (end facing up)
