Engine Bay Insulation for Mobile Equipment

Engine Bay InsulationEngine bay insulation for mobile equipment keeps heat and noise in the engine compartment from reaching the cab interior. The diesel engines that power mobile equipment run hot and loud, which raises concerns about occupant comfort, health, and safety. Mobile equipment manufacturers also need to protect cabin components such as instruments from sound-induced vibrations. For a complete engine bay solution, Elasto Proxy makes thermal-acoustic insulation that can also dampen vibrations.

With mobile equipment, the cab where the operator sits is right next to the engine compartment. Unless adequate engine bay insulation is attached to the firewall, heat and sound from the engine will spread to the cabin. Cab insulation helps, but you need a complete solution. Elasto Proxy makes firewall insulation, and also fabricates insulation that’s installed under the cabin floor. This thermal-acoustic insulation is important in mobile equipment designs where the cab is directly above the engine compartment. (more…)

Cab Insulation for Mobile Equipment: Head Liners, Side Panels, Door Panels

Cab InsulationCab insulation for mobile equipment absorbs sound and provides a finished appearance to cabin interiors. Headliners, door panels, and side panels are made of perforated vinyl foams that, depending on the amount of cabin noise, are typically 1/2” or 1” thick. This acoustic insulation can be hand-cut and applied with spray adhesives, but that process is labor-intensive, results in material waste, and raises health and safety concerns. Fortunately, there’s a better way to get the cab insulation that you need.

Elasto Proxy uses value-added manufacturing to create custom cab insulation for mobile equipment. Water jet cutting makes precise cuts with straight lines or chamfered angles. Taping replaces adhesive spraying with peel-and-stick installation. Kitting, parts marking, and packaging put everything your installers need at their fingertips. Elasto Proxy offers design assistance and help with material selection, too. By choosing cab insulation from Elasto Proxy, you’ll save time and money while improving quality. (more…)

Mobile Equipment Insulation: Get the Sample Kit

Mobile Equipment InsulationMobile equipment insulation absorbs sound and deflects heat, helping to keep drivers and operators safe and comfortable. Materials of construction vary, but generally include foams, foils, and facings. For mobile equipment manufacturers, the process of cutting, assembling, and installing thermal insulation and acoustic insulation can result in material waste and concerns about product quality. Manufacturers risk losing sight of their true costs, and potential buyers may notice imperfections in cab and vehicle interiors.

Manufacturing Costs and Quality

Buyers who closely examine a product’s details can draw positive or negative conclusions about overall quality. Door seals that are bonded properly make a good first impression. So does cab insulation that’s cleanly cut and neatly installed. Insulation that’s cut from a template with a utility knife or a box cutter may seem cost-effective, but do potential buyers see uneven cuts and gaps between parts? How much material gets scrapped when installers struggle to make straight or chamfered cuts? (more…)

Gensets: Door Seals, Acoustic Insulation, and Rubber Bumpers

GensetsGensets or generating sets are designed to supply off-grid electricity. They usually consist of a diesel or gasoline-powered engine and an electrical generator (such as an alternator) that converts mechanical power into electricity. Some gensets, such as the ones that provide emergency backup power at hospitals and water treatment plants, are large and stationary. Others gensets are portable because they’re wheeled, or are mounted on wheeled trailers that are pulled by trucks or other motorized vehicles. (more…)

Silicone Gaskets with High Flex-Fatigue Resistance

Flex Fatigue ResistanceElasto Proxy custom-fabricates silicone gaskets with high flex-fatigue resistance. These specialty gaskets are made of materials that meet the A-A-59588 3B specification for 50, 60, and 70-durometer silicones.

Silicone gaskets have many desirable properties. They’re chemically inert, resistant to ozone and ultraviolet light, offer thermal stability over a wide temperature range, and can repel water and form watertight seals. Silicone rubber is used in a variety of sealing and insulation applications, but some silicones have inadequate flex-fatigue resistance – a measure of a material’s ability to withstand repeated flexing or bending without cracking.

In some industries, however, flex-fatigue resistance is required. For example, aerospace engineers need silicones with high flex-fatigue resistance for door seals, window seals, and vibration-isolating mounts used with alternators, compressors, and assembly bolts. Members of the mobile equipment industry need crack-resistant silicones for engine mounts and exhaust hangers. Designers of aerospace and defense electronics need silicones that can flex without cracking in high-performance keypads. (more…)

Custom Weather Stripping for Doors and Windows

custom weather strippingCustom weather stripping from Elasto Proxy can meet the challenges of static or dynamic sealing in hot or cold weather conditions.

Here in the northern hemisphere, the days are becoming colder. In Canada, where Elasto Proxy is headquartered, the snows will arrive long before December 21, the first day of winter. At offices and factories across North America, doors and windows that let warm air out and cold air in mean higher heating costs. Leaky door and windows can also make occupants less comfortable and workers less productive.

Standard weather stripping can help, but what if your sealing and insulation application requires a specialized solution? After all, off-the-shelf rubber products aren’t designed and manufactured with your specific needs in mind. For a custom sealing solution you can count on, choose weather stripping from Elasto Proxy. All weather stripping isn’t the same, and selecting a custom-fabricated rubber product can save you time and money in the end. (more…)

Silicone Hatch Seals Resist Compression and Temperature

Silicone Hatch Seals | ST-375-23-SM
Silicone Sponge ST-375-23-SM

Elasto Proxy custom-fabricates silicone hatch seals for demanding applications. These specialty gaskets support superior sealing with good compression set and temperature resistance.

Gasket designers want rubber hatch seals that are as tough as the vehicles, equipment, and infrastructure that need them. If a hatch seal can’t withstand compression, it may over-compress and admit wind, water, dirt, or mud. If a hatch seal can’t withstand a wide range of temperatures and outdoor environmental conditions, seal failure can result, too. If you need hatch seals for military vehicles, mobile equipment, marine applications, or HVAC systems, there’s plenty to think about. Fortunately, help is available.

For every hatch seal design, compound selection is critical. As readers of this blog learned last March, choosing the right rubber won’t stop enemy fire, but choosing the wrong rubber can result in over-compressed hatch seals on military vehicles. That’s why although neoprene rubber offers an excellent balance of material properties, this elastomer wasn’t the best choice for the military gaskets that Elasto Proxy inspected. After examining the results of over-compression, we recommended silicone sponge rubber seals instead. Is this same elastomer right for your application, too? (more…)

Rubber Door Seals for Passenger Rail Cars

Rubber Door SealsIn this case study, you’ll learn how Elasto Proxy applied its expertise in seal design, compound selection, custom fabrication and logistics to supply rubber door seals for passenger rail cars. How can we help you solve your sealing and insulation challenges?

Manufacturers of mobile equipment need to source rubber parts that meet all of their application and business requirements. When a manufacturer of mass transit vehicles needed to replace the door seals on passenger trains, Elasto Proxy applied its expertise in technical design, compound selection, custom fabrication, and logistics. In solving this sealing challenge, Elasto Proxy improved the original seal design and helped the mobile equipment manufacturer meet the urgent needs of an important customer.

As the rail car manufacturer explained to us, the existing seals on some passenger cars had become worn and were leaking. The manufacturer’s customer, a major passenger rail service in the Northeastern United States, wanted to solve this problem quickly. In turn, Elasto Proxy needed to create new door seals in less than two weeks and send them to Philadelphia for installation. Since the “test train” for these replacement seals would remain at the station for less than 24 hours, ease-of-installation was also important. (more…)
