Rotary die cutting is a quick, cost-efficient way to manufacture products that require precise shapes, cuts, and folds without sacrificing speed of construction. This makes it a great way to build mass-produced items like boxes and other packaging from paper, plastic, and metal, as well as electronic component assembly parts, decals, stickers, foam products, and more.
Although other die cutting methods exist (such as flatbed, matched metal, and laser die cutting), rotary die cutting is often the best choice for industrial uses. It is quicker than both flatbed and laser die cutting and it can easily manage heavy or tough materials.
HOW ROTARY DIE CUTTING CAN STREAMLINE YOUR PRODUCTION PROCESS
Although all types of die cutting bring their own benefits—and in some cases, you might use more than one method for the same die cutting project—a rotary die cutter offers several advantages that place it above other methods:
- Ease of cutting: Rotary die cutting machines can cut through just about any material, from paper and magnets to foam, metal, and cork, at efficient speeds.
- Speed and efficiency: Rotary die cutting is an excellent choice for completing large production runs. Since the cutting pattern is set in the machine, it does not need to be adjusted between cuts, meaning that it can process large amounts of material with little to no error.
- Quick turnarounds: Rotary die cutting’s efficiency makes it easy to move materials from concept to finished product.
- Precision: Rotary die cutting replicates precise cuts, so you can be sure each item you produce is identical to the last. It’s the most accurate die cutting option, which is why it’s often favored for production runs that require consistency and uniformity.
- Less waste: Rotary die cutting creates less waste than other procedures, which is both more economical for the company and more sustainable for the environment.
- Multipurpose: Rotary die cutters can perform several tasks depending on the project’s needs, such as laminating, kiss cutting (to create adhesives), embossing, and more. They can also perform inline packaging as required.
- Durability: Rotary die cutting machines rely on straightforward processes that result in minimal wear and tear on components.
CUSTOM DIE-CUT PARTS FOR ANY APPLICATION
Because rotary die cutting is so effective for creating metal products, it’s commonly used to build electronic parts. Due to their conductivity and malleability, metals like copper, nickel, aluminum, and silver are regularly used for electronic components like capacitors and transducers. These metals are all easily cut with rotary die cutting.
But that’s not all: many other industries use rotary die cutting to quickly, efficiently, and accurately produce all sorts of small products. Some of the most prevalent manufacturing sectors that use rotary die cutting include:
- Shipping: Shippers use rotary die cutting to manufacture cardboard boxes, envelopes, tickets, stickers, labels, and more
- Medical devices: Rotary die cutting consistently delivers the precision and detail required to create a wide array of medical parts
- Aerospace and automotive: The method is regularly used to create heat shields and sensitive navigation components
- Appliances: Rotary die cutters work with a wide range of materials to create sound-dampening foam products for use in appliances

Electromagnetic interference (EMI) — also called radiofrequency interference (RFI) when occurring in the radiofrequency spectrum — refers to an electromagnetic disturbance caused by an electronic device interacting with another electronic device. Electromagnetic induction, electrostatic coupling, and conduction can all disrupt the electrical circuit of the affected device. EMI can cause major problems for a huge range of applications, and is becoming a greater concern in today’s increasingly connected world.
Ever wonder why wireless devices must be put on airplane mode or turned off during a flight? Electromagnetic waves emitted when using those devices can actually interfere with the plane’s navigation system.
As the use of technology and electronic devices continues to rise, the EMI shielding market is rapidly expanding. Government guidelines outlining EMI shielding requirements are also expected to shift. And as technology use increases, electronic devices are becoming smaller and smaller, and the use of Wi-Fi, GPS, and Bluetooth is becoming more and more common. Both of these trends — the miniaturization of devices and the increased use of wireless technologies — can contribute to EMI problems.
EMI SHIELDING MATERIALS
EMI shielding is extremely important in today’s ever-shifting landscape, and we’re proud to partner with Parker Chomerics, a leader in EMI shielding innovations offering a range of different of products including:
EMI SHIELDING GASKETS
EMI shielding gaskets from Parker Chomerics can eliminate all types of EMI gaps. Common applications include EMI window seals, grounding tabs, server face plates, panel seals, cover seals, and door seals.
EMI SHIELDED WINDOW
These windows not only guard against EMI, they also protect displays from scratches and breakage, and can withstand harsh conditions. EMI shielded windows can be used with the above-mentioned EMI shielding gaskets, as well. Common applications include electronics used in military and medical environments, instrument panels, and cabinets and racks.
METAL FOIL TAPES
Parker Chomerics offers a few different types of shielding tapes, available in aluminum, copper, tinned copper, nickel-plated, and, if appearance is a concern, embossed types. These tapes are perfect for EMI cable shielding, especially when dealing with surfaces that cannot be soldered.
EMI SHIELDING PAINTS
Paints are ideal for scenarios in which common EMI shielding products will not work, such as high-altitude environments. You would not want to wrap EMI shielding tape around an airplane, for example. Parker Chomerics offers a range of different paints to suit specific shielding applications, such as circuit boards, plastic enclosures, electrolytic platable plastic, aircraft airframes, and aluminum and composite.

Dow Corning® has demonstrated time after time its endearing qualities as a global leader in adhesive silicone adhesive technology and products; the company has done it again with the introduction of its new Dow Corning® EA-7100 Thermal Radical Cure (TRC) Adhesive. With its 2015 nominations for the prestigious R&D 100 Award in both the Market Disrupter category and the Mechanical Devices/Materials category, Dow’s new TRC adhesive promises to offer “game-changing benefits” to its customers in the transportation electronics sector.
Among the potential applications for this breakthrough in adhesive technology are the assembly of electronics housings, the attachment of connectors, electronic control units (ECUs), lighting and display modules, or sensors, to an unprecedented variety of substrates.
A BREAKTHROUGH IN ADHESION AND CURE TIME
The list of materials that EA-7100 has demonstrated compatibility with include metals such as aluminum, brass, copper, and steel, as well as ceramics, glass, laminates, silicones and plastics that typically haven’t had good cohesive adhesion properties. Compatibility is possible with polymer plastics such as polycarbonates and polyethylenes (including LDPE and PEX), Nylon, acetal plastics, Plexiglass®, PVC, liquid crystal polymers, and cured silicones; often without pretreatment or specialized cleaning. Dow indicates that it expects this list to continue to grow as new applications are developed and tested, and there is no doubt that robust adhesion to such a diverse range of materials will enable new product designs that may revolutionize the manufacturing of automotive electronics.
The unique ability to bond to so many substrates magnifies the overall performance of TRC adhesives when presented with their low voiding and significantly reduced cure time compared to conventional heat-cure, platinum catalyzed silicone adhesive systems. The adhesive has demonstrated the ability to achieve a full cure in as little as 15 minutes at 100°C compared to the longer 60 minute cure time of conventional single-part, addition-cure adhesives at 125°C. In some applications, cohesive adhesion begins in as little as 3 minutes, a quality that, along with lower cure temperatures, is sure to increase production efficiency in the manufacture of transportation and automotive electronics products. This highly effective curing process yields lower energy use and lower material processing costs.
A NEW KIND OF CURE
With the onset of cohesive adhesion occurring in as little as 3 minutes, Dow Corning’s EA-7100 can cure to a wide range of substrates simultaneously. Curing and adhesion begin before skin-over, in bulk, and at the bond line, and 100% adhesion is achieved immediately after cure time. While the adhesive surface exposed to oxygen remains tacky until its dual cure system is completed, the cohesive adhesion allows for immediate hot testing, and surface tack can be reduced by curing the adhesive in a low oxygen oven.
Typical “addition cure” silicone adhesives have shown sensitivity to certain contaminants such as amines or sulfur, that interfere with bonding, but EA-7100 has proven to be unaffected by either. As a thixotropic adhesive with reduced viscosity under agitation, it requires neither extensive cleaning before application nor pre-treatment in most cases. With little to no cleaning or pre-treatment required, primers, plasma, and UV or corona processes can be reduced and possibly eliminated in some applications, another cost reducing benefit.
ENHANCED ADHESIVE PERFORMANCE
What does it take for a high-performance silicone adhesive to claim the title “high performance?” It’s more than just versatility among a variety of applications and substrates, lower cure temperatures, and less cure time; it also requires enhanced adhesive properties. Properties such as adhesion, shear, tensile strength, resistance to corrosion, and superior reliability under water immersion and salt water spray environments make Dow Corning EA-7100 stand out as a high-performance adhesive.
EA-7100 shows adhesion strength up to 350 PSI to aluminum substrates, while adhesion to PBT thermoplastics such as Ticona® and BASF® is even higher; up to 380 PSI at 100% cure. With a Shore A durometer hardness of 43, it’s tensile strength is a whopping 490 PSI, and its shear strength on aluminum and PBT substrates is over 350 PSI (after only 30 minutes of cure time).
GREATER DESIGN FLEXIBILITY AND COST CONTROL
Dow Corning EA-7100 Adhesive was developed to give manufacturers of automotive electronics and electronics modules greater design flexibility and cost control. This innovative one-part thixotropic adhesive technology widens the possibility for new, improved models with more superior performance potential and more cost control than previously available for applications in automotive and transportation electronics.
Durable adhesion to a wide range of substrates is formed simultaneously with the cure, increasing the flexibility of new product designs. Both faster cure times and lower cure temperatures increase production efficiency and reduce energy costs. Small void formation, reduced sensitivity to contaminants, and improved adhesion in harsh environments including hot and cold temperature extremes, salt spray exposure, as well as both fresh and saltwater immersion also enhances new design possibilities.
MORE APPLICATION POSSIBILITIES
The opportunities for applications in the manufacturing of transportation and automotive electronics are as diverse as can be expected for a Dow Corning adhesive product. EA-7100 can be considered for a variety of uses in the assembly of plastic and metal electronics housings and components, as well as for attaching electrical connectors, lighting components, and sensors to a wide range of substrates.
Possibilities for powertrain applications in the electronic management of engine performance and emissions, control of automatic gearboxes, and in the management of power steering and braking functions include various ICU modules and sensors that can benefit from this new adhesive technology. Safety and driver assistance sensors and controls such as those used with airbags, crash detection, tire pressure monitoring, adaptive lighting, and speed control functions would also benefit from this innovative adhesive technology. There are numerous applications in driver and occupant comfort, climate control, power accessories, and power distribution as well.
