Blogs, white papers, videos and pillar pages talking about machined RF shields - the idea is or was to start creating inbound content in 2019 to attract more people to our website. It’s my understanding that if we did a good job publishing content, our engineering friends would somehow just get it and start specifying our products and services. In case you didn’t know, our customers are supposed to be 60% sold by the time someone from Modus™ actually talks with them! I absolutely love the idea, but in today’s content overloaded world, I’m not convinced the model works.
Just like a 500-horsepower sports car, SigShield™ certainly isn’t right for everyone. If you’re sitting in stop-and-go traffic (a nod to our friends in the Bay Area!), the only thing you’re going to be able to do with your 500-HP motor is to listen to it purr. No, not everyone in the Bay Area drives a Tesla, yet! The SigShield™ product realization process fits perfectly in certain situations. The real purpose of this post is to identify a few circumstances where SigShield™ might be an attractive option.
If you make a mistake during the design phase, you run the risk of going over budget and not receiving your solution in time. Our latest eGuide will help you avoid these common design oversights. Get a free copy by subscribing to our blog.
What makes Modus™ unique is as much our process as it is our product. Not just the standard and expected process of manufacturing, but the dedication to evolution in our work for the benefit of our customers. Our custom machined RF shields are the perfect example of this commitment in action. The SigShield™ product realization process was specifically created to help customers meet demanding project requirements and the insane deadlines they face.
Historically a rubber seal and gasket company, Modus Advanced, Inc. recently ventured into the machining business due to increased demand for quick turn RF shields. We now produce complete radio frequency (RF) shields from start to finish, beginning with the machining of the aluminum to the dispensing of a form-in-place (FIP) gasket.
Engineers can spend days or even weeks designing the ideal aluminum RF shield for their application. Fastener placement, wall thickness, cavity location, materials and many other factors are engineered to optimize performance. When Modus Advanced, Inc. began milling RF shields, the company was faced with a question; which of the many choices of measuring equipment is best suited to verify our processes are producing shields that meet customer’s specifications?
Silicone form-in-place (FIP) electromagnetic interference (EMI) shielding gaskets have a job to do. The electrically conductive FIP gasket bridges the gap between machined aluminum shields and PC boards create a faraday cage. When designed correctly, machined aluminum shields with conductive FIP gaskets provide effective EMI protection for sensitive electronics. What does “designed correctly” mean? There are obviously many factors that affect shielding performance. They’re all fun and exciting to talk about, but our focus in this blog post is on the use of mechanical compression stops to help avoid gasket related issues.
Additive manufacturing (AM), or three-dimensional (3D) printing, is the process of creating a 3D solid object of nearly any shape from a digital model. The technology has lead to innovations in a vast array of industries since the 1980s. The process has widely contributed to the biomedical field with the creation of biocompatible veins, to national security with the production of unique parts for the U.S. nuclear weapons stockpile, and to aerospace applications by more rapidly and simply generating products needed for unmanned aerial vehicles and satellites, among other notable applications. While already impressive, AM technology only continues to mature and diversify.
Regardless of industry, designing a custom product is a challenge in itself, let alone unleashing the design into production. So how can your company ensure it is selecting the best production methods for your unique product? Efficient manufacturing requires forethought, planning and exceptional components. Design engineers want prototypes quickly and, in order to stay in the game, manufacturers must perform.
Read our latest case study to learn how Modus Advanced, Inc. collaborated with LORD Corporation to solve difficult vibration and shock problems with advanced testing procedures and system re-engineering.
‘Leaving it to the experts’ can be a mutually beneficial proposition for both the expert and the other party. In industry, this concept is a convenient way of allowing both parties, each familiar with a certain field, to hone their skill set and become trusted, esteemed experts in that field.
Component manufacturers with poor quality control can jeopardize your engineering projects. Form-in-Place (FIP) gaskets, die cut gaskets, and custom molded rubber products with part defects may not perform as required. Custom-fabricated components that fail to arrive on-time may cause delays in product development, production, and assembly. These are just a couple of reasons engineers need to be aware of how quality-focused their custom parts supplier is.
When you have a need for “speed”, quick-turn parts can be your salvation! The production of quick-turn parts necessitates both quality methodology and a single supply chain comprised of multiple manufacturing steps. Engineers can achieve both quality and quick-turn through vertical integration. This approach combines the production of base components and supporting processes all under one roof, saving time and money by shortening your supply chain to one manufacturer!
Is your design complicated and you’re looking for a cost effective but reliable sealing solution?
Mechanical Engineers often face tight deadlines when trying to design new RF shields with form in place gaskets. Projects that seem simple can quickly become complex when multiple components must come together in a timely manner to achieve production goals. Cost overruns, delays, defects, and poor risk control present significant barriers to project success.
Sustainability, renewable resources and environmental awareness aren’t just buzzwords to toss up on a website. Today, the world is more aware than ever of the effects of human activity on our planet. With humans speeding climate change up to 170 times faster than natural forces, organizations have a responsibility to find ways to be more sustainable, even if there’s a cost associated with it. In the past, manufacturing was a notorious culprit of industrial pollution. Now, with so many new sustainable technologies out there, industry has an opportunity to shrink its footprint and invest in the future. Of course, the short-term setup costs can be intimidating. But in the long run, investments in green manufacturing technologies can save money and keep our planet healthy. A win-win!
Early on, in my career as a Tool Engineer, I had the opportunity to work extensively with compression molds and the compression molding process. At the time, rubber compression molding was an ideal way to produce the O-rings and seals made in the silicone, fluorosilicone, and nitrile elastomers that my customers wanted.
Gaskets are everywhere and all engineers today understand their importance in the creation of reliable, quality products. Die cut gaskets are used in everything from medical equipment; to military hardware; to the hand-held devices that most of us now carry 24 hours a day. Effective gaskets are designed to shield sensitive electronic components from the environment, vibration, heat, dust, electromagnetic inference, and the nemesis of all electronics – water.
EMI gaskets can be fabricated through a variety of methods. The most common techniques tend to be die cutting and compression molding. Some shielding gaskets, such as EMI O-rings, can be cut by hand and then cold-spliced or vulcanized. Water jet cutting and digital or die-less cutting are also used in EMI gasket fabrication. These methods are good choices for prototyping and lower-volume production because there’s no custom tooling.
Nickel-graphite silicones are cost-effective compounds that combine the advantages of silicone rubber with the electrical properties of nickel. They are fabricated into gaskets and installed between metal surfaces to provide limited environmental sealing, excellent electrical conductivity, and resistance against electromagnetic interference (EMI). Nickel-graphite silicones aren’t the only shielding elastomers for EMI gaskets, but they offer advantages over silicones that are filled with silver or silver-coated particles. To determine whether nickel-graphite silicones are right for your sealing and shielding application, it’s important to evaluate all of your business and technical requirements.
From time to time, while working as an Applications Engineer at LORD Corporation, I would get a call from a customer who was concerned the bond would fail on the vibration isolator mounts they were considering using. After all, a vibration mount is a rubber-to-metal bonded product in which an adhesive bonding process is used to manufacture it. I could easily see how this would be a concern, especially if someone doesn’t often deal with adhesives or is not familiar with the rubber-to-metal bonding process. During these conversations, when I point out LORD uses its Chemlok® adhesive in the bonding process, the customer is immediately reassured that the bond on a vibration isolation mount is most certainly not the weak link.

In this article we’re going to explore the typical 5 step process used to bond or vulcanize rubber to metal.
Die cut gaskets for EMI shielding and other applications are reliable, customizable, and cost-effective. As a manufacturing technique, die cutting combines proven technologies with efficient approaches to gasket fabrication. Specific die cutting techniques vary, but most methods involve two core components: a metal tool called the die, and the die cutting machine itself. Die cutting is a smart choice for connector gaskets, but it’s also used to produce many other types of seals and insulation.
The purpose of EMI shielding gaskets is to protect and enhance the performance of electronic devices and equipment by creating a conductive path between two surfaces. The gaskets work to ensure the electrical conductivity required in your design is reliable and solid. Additionally, and maybe more important, they prevent the transmission of electromagnetic interference (EMI) disturbances which can disrupt or destroy electrical circuits. This article explores the top four EMI shielding gasket manufacturing methods.
Form-in-Place (FIP) gaskets are becoming a cost-effective seal of choice for densely populated electronics packaging where isolation and complex cross section patterns are required. Let’s examine a couple of considerations inherent in FIP gaskets, starting with some of these more obvious benefits:
In my 34 years as a LORD engineer, the last 8 years being devoted to shock and vibration applications, I feel that I’ve seen and heard it all! During my tenure, I cared a lot about safety and stressed the importance of using vibration mounts that incorporate a “safetied” feature, as should you.
We all know that necessity drives invention and paves the path to progression, so when Elon Musk found himself in traffic during his commute between SpaceX and Tesla, the idea of faster and less congested travel became imminent...Enter the Hyperloop. In 2013, with the help of volunteer engineers from SpaceX, Elon’s idea evolved into a white paper called “Hyperloop Alpha”, aka: The Alpha Paper. The Alpha Paper outlines every aspect of this new technology engineers could conceive; from design of the tube and capsule to the method of propulsion. The proposed route is a 350 mile round trip journey from LA to San Francisco, testing subsonic speeds for feasibility, functionality and ideally, comfort.
There’s always potential disruptions in the manufacturing process – materials may not be readily available; customer requirements may have been overlooked when a project was quoted; perhaps changes were made to the design after receiving a quote that didn’t flow through to the purchase order. These hindrances are frustrating and may possibly delay product shipment, but shouldn’t completely derail gasket production.
Electromagnetic interference (EMI) can disrupt electronic devices, equipment, and systems that are used in critical applications. Examples include medical, military, and aerospace electronics; mass transit systems; industrial touch screens; and navigation and vehicular control systems – just to name a few. The causes of EMI are numerous, and include both man-made and natural sources. The results can range from temporary disturbances and data losses to system failure and even loss of life.
If you had called 877-ASK-LORD within the last several years, chances are you probably talked with me! Through my 34 years with LORD Corporation, I’ve had the opportunity to work as a Tool Engineer, designing all types of tooling used to manufacture LORD products; as a Product Engineer, providing design support to many of the LORD Industrial customers such as Caterpillar and John Deere; and most recently as an Application Engineer, providing technical support to LORD Industrial Distributors and their customers.
Facing thermal challenges in your current design? Interested in learning about industry leading thermal interface materials? Want to influence new thermal interface material product development? Need non-biased, outside perspective from a thermal technical expert?
As you’re probably aware, there are many different types of Thermal Interface Materials (TIMs) on the market. With so many variables, picking a thermal pad versus a form-in-place solution can be complex. Some of the variables include: Choosing the optimal supplier Form (dispensed filler or discrete pad) Thermal conductivity When you add company specific performance requirements, selecting the right thermal pads or paste can be even more challenging.
In the days before last November’s presidential election, Forbes magazine asked “Which Candidate Can Make American Manufacturing Great Again?” Today, that question is irrelevant. Whether you love him or hate him, Donald J. Trump – and not Hillary Clinton – is President of the United States. That much is clear, but it’s uncertain what the future holds for U.S. companies that have moved operations to places like China and Mexico.
Electronic components produce heat when they operate. How these products manage their heat generating and cooling systems determines how functional and reliable they are. Thermal dissipation greatly contributes to the performance and longevity of various products, especially electronic devices. Since electronics generate power, fluctuations in temperatures can occur. When temperatures get too high, there needs to be a way to wick the heat away from the components to a heat dissipating mechanism, such as a liquid cooling plate, chassis or traditional heat sink. For instance, if a Printed Circuit Board (PCB) does not have a way to transfer heat, the reliability and longevity of its components will be adversely affected. In extreme cases they can even melt or become damaged. Thermal Interface Materials (TIMs) are used to transfer heat away from the heat source and onwards in the cooling chain.
WE ARE MODUS! The day came and went. Last month we said goodbye to the name Western Rubber & Supply. For 40 years, our name signified comprehensive capabilities, innovative materials, and an unparalleled commitment to our partners' satisfaction.
We carry an extensive line of Lord mounts, which are designed to manage the vibration, noise and shock that can cause mechanical systems to fail. The key to isolating vibration is to reduce its transmission to a component or supporting structure. In a nutshell, the rubber in a mount acts as a spring with its own natural frequency, and this frequency partly depends on the stiffness of the spring. But why is rubber such an ideal material in this type of situation?
