Converting 3M 3340
3M 3340 can be easily die cut and converted into custom formats depending on your needs.
Slitting: Strouse can slit rolls of aluminum foil tape to custom widths. This provides you tape in the exact width you need for your task at hand. No excess or waste and no more using rolls that are too large and bulky or too small to get the job done.
Die Cutting: This is the process of cutting a wide roll of aluminum foil tape into a custom shape or usable part for your process. Parts can be cut into different formats to fit seamlessly into your assembly.
Individual pieces – Foil tapes can be laminated with liner on the adhesive leaving no exposed adhesive. This means that when parts are die cut they are provided as individual pieces that can be placed inside a bag.
Sheeted Parts – Some assembly processes require multiple shapes or parts of the same material. This is where sheeted parts come in handy. Multiple parts can be cut onto a single sheet ensuring that your employees will use all of the required parts during assembly. This reduces error in your process as well as the potential for product failure.
Die Cut Parts on a Roll – This is our most popular format for providing die cuts. Custom cut parts can be provided on a liner in the form of a rolled good. This allows for hundreds or thousands of parts to fit on a single roll. This makes application of die cut parts easy and efficient as parts can be removed from the roll and the next part is ready to be peeled and placed.
Tabs or Extended Liners: Die cut solutions are great for hand assembly or automated processes but sometimes removing the backing from an adhesive die cut can be difficult. Strouse simplifies this process by adding a tab to the part or extended liners that make it easy to remove the liner and place the adhesive. Liners can also be split backed saving your assembly team the frustration of removing thin liners while saving you time and money in the process.
