The Basics of the Rotary Die Cutting Process
Rotary die cutting is a common process used to manufacture simple two-dimensional labels, but rotary die cutting is used for more than just labels. Marian uses rotary die cutting to manufacture complex custom 3D components with multiple layers of differing geometries used in some of your favorite everyday products.

Many wound care device companies start with an innovative idea. Turning that idea into a mass-produced product can be extremely challenging. This concept is familiar to KitoTech Medical,a Seattle-based medical device company that develops wound care products. Kitotech was founded by Ronald Berenson, MD. Dr. Berenson is a serial entrepreneur with over 25 years in biotech and medical device industry. Marian is proud to call KitoTech Medical a valued customer.

There are many EMI shielding materials to choose from when determining how to effectively control EMI within an electronic device. In this post, we focus on die-cut foil tapes for EMI shielding. Foil tapes with conductive adhesive provide effective shielding properties as the thin foil layer ensures good electrical contact with the component surface. Let's take a look deeper at EMI and why foil tapes may be the best-suited material for your application.
What is EMI and Why is it Important?
Electromagnetic interference is unwanted “noise” or interference in an electrical path or circuit caused by an outside source. EMI can be caused by natural or man-made sources and can cause electronics to malfunction or to completely stop working. Therefore, EMI shielding and grounding components are important pieces in the design of electronic devices.

Marian is a converter of thin, flexible materials. Most often, these materials are supplied to us in a large roll format, sometimes called “master rolls” or “log rolls”. The materials are typically on a hard-fiber or plastic core.
As you can see on our Materials webpage, Marian converts a wide range of material types in a myriad of different thicknesses. These include pressure-sensitive adhesives and tapes, sponge and foam, rubber, plastic films of all sorts, filter fabrics, foils, and more.

Double coated foam tapes are a type of adhesive tape that is made of tacky adhesive coated on both sides of a foam core or carrier. DC foam tapes fill gaps and distribute stress uniformly over the bonded area. Depending on the specific tape, the result is a bond line that seals, cushions, and damps vibration, resists impact, withstands a wide temperature range, and provides good insulating qualities. Double-coated foam tapes are strong and durable.

Thermal Runaway Propagation Prevention with Thermal Barrier Materials
Hybrid and battery electric vehicles that use lithium-ion cells require that these cells are maintained at specific ambient temperatures. "Thermal runaway" occurs as a result of the rapid rise in temperature within one of the battery cells. One of the greatest challenges for battery design engineers is to manage heat. For this reason, batteries are designed with thermal management systems, like thermal gap pads and thermally conductive tapes, that provide different levels of protection, including cell-to-cell, module-to-module, and pack level.
Marian provides custom flexible die cut solutions that are incorporated into battery design at the cell, module and pack level to aid with thermal management. These die-cut parts are made with high temperature resistant materials (also known as flame barrier materials) that are designed to offer thermal insulation to delay the onset of thermal runaway.
