  • The True Costs of Industrial Rubber Products

    True CostsWhat are the true costs of industrial rubber products such as seals, gaskets, and insulation? Buying rubber materials and fabricating them in-house may seem cost-effective, but is your company really saving money? For that matter, are you sacrificing quality, consistency, and potential sales opportunities for a questionable cost savings?

    Companies that want to know the true costs of industrial rubber products need to understand the full scope of their manufacturing costs. Typically, these costs are divided into three categories: direct labor, direct material, and manufacturing overhead. If any of these costs are incorrect, your financial statements may under-report inventory value and the cost of goods sold.

    In this article from Elasto Proxy, we’ll examine each category of manufacturing costs so that you can consider how your in-house operations compare to outsourced fabrication. By understanding your true costs, you can make better business decisions and strengthen your manufacturing operations. Continue reading

  • Abrasive Water Jet Cutting vs. Guillotine Cutting for 45° Cuts on Bulb Trim Seals

    Abrasive Water Jet CuttingAbrasive water jet cutting and guillotine cutting can both produce 45° cuts on bulb trim seals, industrial rubber products that may contain metal wires. Abrasive water jet cutting uses a high-velocity, high-pressure stream of water and abrasive to cut through rubber, metal, and many other materials. Guillotine cutting uses a miter saw or metal blade instead. Like abrasive water jet cutting, guillotine cutting can cut through rubber profiles that contain metal reinforcements.

    For buyers of bulb trim seals, choosing the right cutting method involves a comparison of manufacturing costs. Compared to guillotine cutting, abrasive water jet cutting has higher hourly rates. Yet abrasive water jet cutting can also produce higher volumes of better quality cuts in less time. Cutting a 45° angle is challenging, even for an experienced guillotine operator. If the employee cuts too quickly, the wires won’t cut cleanly. This requires surface finishing, which adds labor costs and extends cycle times.

    As this article explains, abrasive water jet cutting can cost less than guillotine cutting for 45° cuts on bulb trim seals. Let’s look at an example to understand why this is the case. Continue reading

  • Gasket Compression in Metal Housings and Assemblies

    Gasket CompressionGasket compression in metal housings and assemblies can support sealing or contribute to gasket failure. That’s because rubber gaskets are resilient, but only to a point. Compressing a gasket within allowable limits forms a reliable seal. When a gasket is over-compressed, however, the rubber won’t rebound when the compressive stresses are removed. This creates a gap between the gasket and the surface of the housing or assembly. Gaps cause leaks, and seals that leak won’t support your designs.

    Material scientists calls the permanent deformation of the gasket material “compression set”, a term that’s used widely but not always fully understood. Engineers need to know the basics of compression set, but they also need to consider its limitations as a test method. With housings and assemblies, it’s essential to account for the entire application environment, including variables such as temperature and vibration. Relaxation, a related phenomenon, is also associated with gasket compression. Continue reading

  • Four Ways to Cut Rubber Products

    Cut Rubber ProductsWhat’s the best way to cut industrial rubber products like seals, gaskets, and insulation? Manual cutting, die cutting, water jet cutting, and abrasive water jet cutting each offer advantages. They also meet different business and technical requirements. As this article from Elasto Proxy explains, choosing the right cutting method for your application requires a complete and careful analysis. Continue reading

  • Noise Control and Acoustic Insulation: Sound Sources and Frequencies

    Noise Control and Acoustic InsulationAcoustic insulation absorbs, transmits, or redirects sound – a form of energy that travels in waves. Unwanted sounds, or noise, aren’t just unpleasant to hear. They can harm human health, jeopardize worker safety, and contribute to structural fatigue. The consequences of noise can be severe, but its characteristics are sometimes misunderstood.

    In Part 1 of this series, Elasto Proxy shared a surprising example of two machines running at different decibel (dB) levels in the same room. In Part 2, we’ll examine some other sources of noise in the industries we serve. Importantly, you’ll learn why acoustic insulation must account for more than just a sound’s source. Frequency, the speed of the change of the sound, is a key design consideration for noise control. Continue reading

  • Nitrile vs. Neoprene: What’s the Difference?

    Nitrile vs. NeopreneWhat’s the difference between nitrile and neoprene for seals, gaskets, and insulation? Both elastomers provide good resistance to compression set and tearing. They withstand the same range of service temperatures, too. Some grades of neoprene offer excellent resistance to abrasion, but nitrile is known for its abrasion resistance at elevated temperatures.

    Nitrile and neoprene rubber have many similarities, but there are some important differences between these elastomers. In this article from Elasto Proxy, you’ll learn when nitrile is recommended and when neoprene is used. You’ll also compare these common compounds across all a full list of material properties so that you can make the right choice for your application. Continue reading

  • Acoustic Insulation: What You Need to Know About Noise

    Acoustic InsulationAcoustic insulation absorbs, transmits, or redirects sound – a form of energy that travels in waves. Some sounds are pleasant to hear, but others can harm human health, endanger workers, or contribute to structural fatigue. Undesirable sounds, or noise, have characteristics that designers of acoustic insulation need to understand. Without this knowledge, noise problems can cause design-related headaches.

    In Part 1 of this series from Elasto Proxy, you’ll learn about the consequences of noise and discover why its characteristics might not be what you think. You’ll also consider why decibel-level differences in noise sources matter. Then, in Part 2, we’ll examine sound measurements and noise control in greater detail. Along the way, we invite you to contact us with your questions about acoustic insulation. Continue reading

  • Solid Rubber vs. Sponge Rubber: What’s the Difference?

    sponge rubber solid rubberWhat’s the difference between solid rubber and sponge rubber? Both are elastomers, natural or synthetic polymers with elastic properties. Both are also subjected to vulcanization, a process that uses heat and a chemical agent such as sulfur to improve durability. Solid rubber and sponge rubber are available in many of the same compounds, such as EPDM, silicone, and neoprene. They can be extruded into the same shapes or molded into sheets, too.

    At the most basic level, the difference between solid rubber and sponge rubber is about air. Sponge rubber contains balloon-like cells or interconnected pockets that either hold air or permit its passage. Solid rubber doesn’t share this cellular structure. Both types of materials provide sealing and insulation, but sponge rubber provides better cushioning. Solid rubber provides stronger impact resistance. Each type of elastomer has its advantages then, but what else do engineers need to know? Continue reading
