What’s the Best Way to Bond Rubber Gaskets?

Bonding GasketsRubber profiles come in lengths that are cut-to-size and fabricated into finished gaskets. Examples include picture frame or bezel gaskets, O-rings, and gaskets with rounded corners.

There are four ways to bond or join the ends of rubber profiles.

  • Hot Splicing
  • Vulcanization
  • Cold Bonding
  • Molding

Each bonding or joining method has its advantages, but what’s the best choice for your application? Let’s examine each method in detail so that you can make the right decision. (more…)

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. (more…)

Rubber Gate Seal for Water Filtration System Lasts Longer, Resists Disinfection, Adds Business Value

Water Filtration Case StudyWhen a manufacturer of water filtration systems needed a rubber gate seal that would last longer and resist ultraviolet (UV) light, Elasto Proxy provided a value-added solution. This custom gasket doesn’t just resist exposure to water, contact with metal and concrete, and disinfection with UV light. The gate seal also supports ease-of-installation and is ready to ship from Elasto Proxy’s warehouse in Newmarket, Ontario.

The 60-durometer EPDM lip seal (J-seal) that Elasto Proxy provides attaches to the bottom of a metal gate used in water treatment facilities. This rubber seal is also compressed against hard concrete floors and exposed to a range of temperatures. UV disinfection kills waterborne microbes that can make people sick, but ultraviolet light can also degrade rubber materials. Without reliable sealing and strong bonding, gaskets like this can’t meet business or technical requirements.

To provide a complete sealing solution, Elasto Proxy leveraged its expertise in seal design, material selection, custom fabrication, warehousing, and logistics. (more…)

Cold Bonding for Rubber Gaskets

Cold BondingCold bonding for rubber gaskets joins lengths of material without the use of heat. This bonding technique doesn’t require low-temperature conditions, but is called “cold” because no heat is applied to the gasket. By contrast, hot splicing requires either a conventional heat source or infrared (IR) light. Vulcanization and molded corners for rubber gaskets also involve heating gasket materials.

With cold bonding, an adhesive is applied to the ends of the lengths that will be joined together. Different types of bonding systems are available, including compounds that vary in terms of viscosity, chemistry, and material properties. Cold bonding for rubber gaskets can save time and eliminate tooling costs, but engineers need a complete understanding of this joining method before choosing glued gaskets. (more…)

How to Install Rubber Gaskets

Install Rubber GasketsDo you know how to install rubber gaskets for optimal sealing and insulation? If rubber seals are installed improperly, small leaks can admit air, water, dust, light, and sound. That’s a big problem for assembly and maintenance personnel who work in industries like mobile equipment, defense, aerospace, stainless steel and food equipment, infrastructure, and medical and health.

Engineers and sourcing managers can help by specifying the right profile materials, but gasket installation is about more than compound selection. Gaskets can attach with mechanical fasteners, but bolts and screws require tools. Plus, mechanical fasteners can loosen from vibrations. Adhesives are great for gasket installation, but spray-on systems are messy and can raise environmental health and safety concerns.

In this article from Elasto Proxy, the first in a series of “how to” blog entries, we explain how to install rubber gaskets for sealing and installation. In addition to adhesive selection, you’ll learn about key profile measurements. Importantly, Elasto Proxy shares requirements and best practices, too. If you want to learn how to install rubber gaskets, this article is for you. (more…)

Rubber Door Seals for Walk-In Bathtubs

Walk-in BathtubsWalk-in bathtubs allow people with limited mobility to bathe themselves safely and independently. Typically, they’re used in hospitals, healthcare settings, retirement communities, and assisted living facilities. Unlike a traditional bathtub, a walk-in bathtub has a door on the front or side of the unit. This allows users to enter and exit the tub without having to lift their legs over the side. This reduces the chance of slip-and-fall injuries, and also supports wheelchair accessibility.

Walk-in bathtubs feature various door designs and come with various capabilities. Hydrotherapy options include whirlpools and adjustable bubble jets. Units with adjustable shower heads, integral handrails, LED lighting, and inside-the-tub seating are also available. Many walk-in bathtubs now include fast-draining capabilities so that users don’t need to remain in the unit for long periods of time while the bathtub empties. Product features vary, but all walk-in bathtubs need reliable rubber door seals. (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…)
