Finishing Operations
|
Laminating
|
Materials can be overlaminated with various films such as polyester, polycarbonate, or vinyl to provide protection, appearance or effect. Pressure sensitive adhesives can be laminated to films or sheets to facilitate mounting functionality for the finished part. We can put together multiple layers of different materials to create insulators, shielding components or custom constructions for special applications. Copper and aluminum foils are examples of products we utilize for those special needs.
|
|
Slitting
|
Slitting is done to create a back or front slit in a protective liner to provide the crack and peel effect for pressure sensitive products. Slitting is also used as a lower cost alternative to pull tabs on pressure sensitive adhesive-backed products. Power shearing and back slitting, for example, are alternatives to tooling and diecutting. Back slits on parts are also advantageous for strategic part placement where only part of the liner is removed and the part can be handled or positioned easily.
|
|
Die-Cutting
|
Diecutting by means of using Steel Rule Dies is an industry standard for cutting shaped parts or parts with interior cutouts, tabs, or large volume. All of our roll labels are produced using tooling, but in many cases, common die shapes or sizes can use common tools. In our sheet-fed products we utilize Clamshell type diecutters.
|
|
Powercutting Shearing
|
Powercutting is the use of a guillotine power shear with a digital readout controller to semi precision cut films, thin gauge sheets and layered constructions into square or rectangular shapes. Our largest production cutter is 54" wide, but we do special cutting up to 12' for products such as banners and sign inserts. Shearing is our cutting process for rectangular sheet products in gauge metals.
