Here is set of photos showing the progression of vapor polishing a plastic part. The first shot is of the part before polishing. The second is during vapor polishing. We only polished half of it to show the difference in finish that vaporing can offer. The final photo is of the part fully vapored. Many potential customers ask about having us vapor parts that they machined. Normally, we do the machining in house but we also offer vaporing as a service. The thing about vapor polishing though, is that any surface imperfections can be magnified. For example, if you give us a piece of machined acrylic, ultem, or polycarbonate that has heavy feed lines or chatter, the vaporing will bring out the poor finish. The truth is, poor finish in = shiny poor finish out. If your machining is fundamentally good and your surface finish is smooth, vapor polishing can brilliantly polish your plastic parts. Engineers and Machinists should also know that overly aggressive machining can impart stress in the finished parts. This can be problematic during the vapor polishing process because the parts may end up with crazing visible inside the material or on the surface. Ultimately, we like to do our machining in-house so we can be sure the parts our customers receive will be as good as possible. However, If your in-house machining work is strong, you will be very satisfied with East Coast Precision Manufacturing’s vapor polishing service. Can’t wait to hear from you!

Tips for Customers and Engineers Who Want Vapor Polished Plastic Parts
Thursday, October 29th, 2009Milled & Vapor Polished Polycarbonate Coverplate
Monday, September 14th, 2009This part is an example of our milling department’s capabilities. It is machined out of a sheet of polycarbonate and vapor polished to a perfectly clear finish. Engineers designing parts that require visually or optically clear finishes should know that polycarbonate is an excellent material choice. Acrylic works well too but polycarbonate polishes to a clearer finish almost every time.
This part is used in a light housing and is implemented as a lens. The inside of the lens has been cosmetically machined to help with light diffusion.
Vapor Polished Polycarbonate Button
Friday, August 14th, 2009Take a look at some more of our work in polycarbonate. This part was turned on a cnc lathe out of polycarbonate, sometimes referred to as lexan. It features a vapor polished finish and concentric grooves on the face. This part is a button that is backlit by a light. It is believed that the concentric grooves will help diffuse the light.
During the initial quoting and machining phase, we worked closely with the customer while they finalized their design. Sometimes that means making a few, sending them out, and waiting to hear back from them. This close relationship is one that not many other shops can offer. The size of East Coast Precision allows us to be nimble when working with our customers.
Our goal is for each customer to feel as if East Coast Precision is an extension of their business and for them to know their parts are as important to us as they are to them.
Machined & Vapor Polished Polycarbonate Lens Housing
Monday, August 10th, 2009Polycarbonate is a material often found in environments where it may be subject to impact forces. This lens that we machined is no exception. It was milled on East Coast’s state-of-the-art vertical machining centers. To ensure a clear finish, the polycarbonate was vapor polished after machining. In some cases, our customers are not sure what they ultimately need in their plastic parts. When questions, concerns, or changes need to be addressed, our customers speak directly with engineers and machinists that are directly working on their part. That is one of the many benefits of working with East Coast Precision Manufacturing.
If you need plastic machining of polycarbonate or any other materials, we would love to be considered.
