What are common uses for current laminated sheets?

Laminated Sheet - USA Manufactuer

g10 sanded laminated sheets (differently sized)

Paper phenolic laminated sheets (differently sized)

CURRENT, INC. has been manufacturing Laminated Sheets for decades. Our Laminated Sheets are made out of thermosetting resins including Phenolic, Melamine and Epoxy. We also manufacture Carbon Fiber Laminated Sheets. The base materials we use to create our Laminated Sheets include: glass fabric, cellulose paper, or cotton fabric as well carbon fiber. These various substrates are impregnated, “B Staged”, with our resins, and then pressed under heat and high pressure. This process produces a dense homogeneous material, that is easy to tap, saw, drill, and machine.

CURRENT, INC. manufactures their Laminated Sheets in assorted colors and sizes for the convenience of customers, and are equipped to make sheets up to 96″ long. Depending on the grade chosen, Laminated Sheets are anywhere from .005″ to 3.00″ thick. All tolerances meet NEMA standards, but clients are welcome to contact our sales office to get in-depth details on specific tolerances. For closer tolerances we can also offer surfacing grinding.

We can provide custom fabrication upon request, this includes a cut to size. Our quotes are free with no obligation to purchase. All we need is your blueprints and/or specs to provide an accurate quote. For further information or to obtain a quote, you can contact us through e-mail, by phone (203) 469-1337, or by Fax (203) 467-8435.
