  • Bulb Trim Seals: Three Things Engineers Need to Know

    Bulb Trim SealsBulb trim seals are used with doors, hatches, and enclosures. They have two sections: the bulb and the retainer. The bulb section provides sealing and insulation under compressive force. The trim or retainer section presses onto a flange or substrate.

    Elasto Proxy supplies many different types of industrial rubber products, but there are three things about bulb trim seals that engineers need to know. Continue reading

  • Molded Corners for Rubber Gaskets

    Molded Corners for Rubber GasketsMolded corners for rubber gaskets are recommended for applications that require rounded joints, the ability to withstand stretching, or high cycle times. Molding is more expensive than hot splicing or vulcanization, but it’s the only way to create radisued corners. C-press injection molding, a bonding method for rubber gaskets, is ideal for low-to-medium volume quantities but suitable only for solid profiles.

    By understanding how C-press injection molding works and the advantages that molded corners provide, engineers can make strong decisions about gasket fabrication. In this article, the second in a series from Elasto Proxy, we’ll continue our coverage of joining methods. Next week’s content, the last in our series, will examine cold bonding. Continue reading

  • Hot Splicing and Vulcanizing for Rubber Gaskets

    Hot Splicing

    Hot splicing and vulcanizing for rubber gaskets are bonding techniques that use heat, pressure, and a film splice or uncured rubber to join the ends of profiles. Hot splicing uses thin polyethylene (PE) film and either a conventional heating source or infrared (IR) light. Vulcanization uses an uncured rubber compound, along with heat and pressure. Both hot splicing and vulcanization create chemical bonds at the molecular level.

    For engineers, choosing a splicing method for rubber gaskets is an important manufacturing decision. By balancing costs against capabilities, you can get the sealing and insulation solutions that you really need.  Traditional hot splicing, infrared or IR splicing, and vulcanization all have their advantages, but they also have their differences. In this article, the first in a series from Elasto Proxy, we’ll examine each of these bonding techniques in detail. Future articles will cover molded corners and cold bonding. Continue reading

  • FDA Gasket Materials for Food Contact Applications

    FDA Gasket MaterialsFDA gasket materials are used in food contact applications such as commercial kitchens. They meet strict standards from the U.S. Food and Drug Administration (FDA), a regulatory agency that’s responsible for protecting the public health by ensuring the safety and quality of many food products. The FDA’s jurisdiction is limited to the United States, but FDA standards are followed worldwide.

    FDA gasket materials for food contact applications are subjected to rigorous testing. They are non-toxic, non-marking, non-allergenic, and reliable over a wide range of temperatures. These compounds are also tasteless, odorless, and resistant to the natural growth of bacteria. Not all food-grade rubber is FDA approved, however, so it’s important to choose gasket materials with care. Continue reading

  • NSF Gasket Materials for Food Equipment and Drinking Water Systems

    NSF Gasket MaterialsNSF gasket materials are used in commercial food service equipment, water treatment or distribution systems, and other applications that can affect human health and safety. Rubber compounds that are registered with NSF International (formerly the National Sanitary Foundation) must pass rigorous tests to ensure that potentially harmful substances won’t migrate from the gasket material when in contact with food or drinking water.

    NSF standards aren’t regulatory requirements, but failing to use NSF gasket materials can put larger product designs at risk. Conversely, using NSF certified compounds can increase the likelihood of regulatory acceptance. In some jurisdictions, public authorities such as health departments require food service equipment and drinking water systems to meet a specific NSF standard. Buyers also expect to see an NSF mark on products such as commercial ovens or water filtration systems. Continue reading

  • How to Install Edge Trim

    How to Install Edge TrimEdge trim protects exposed edges and the people who come into contact with them. In addition to sealing and insulation, edge trim provides a finished appearance to surfaces such as the metal doors on vehicles, machinery, and equipment. Choosing the right type of edge trim for your application is important, but you’ll also need to install these seals with care. Otherwise, edge trim can buckle or separate.

    In this “How to” article from Elasto Proxy, you’ll learn how to select edge trim based on dimensions and material requirements. You’ll also learn some best practices for cutting trim seals, as edge trim is also known. You can buy lengths in bulk and cut them yourself, or you can buy edge trim that’s been cut-to-size for your application. Either way, you’ll need to install edge trim by pressing the seal onto the edge. Continue reading

  • Unmanned Vehicles: Seals, Gaskets, and Insulation for Marine Environments, Commercial Drones, and Accessories

  • Data Center Cooling Systems: HVAC Seals, Gaskets, and Insulation

    Data Center Cooling SystemsData center cooling systems need to maintain temperatures that support the continuous and reliable performance of information technology equipment (ITE) such as blade servers, networking switches, and routers. If heat isn’t removed from the vicinity of sensitive ITE components, overheating can occur. If servers get too hot, onboard logic will turn-off computers to avoid damage. This protects data center assets, but results in downtime and loss of efficiency.

    Data center servers can run at temperatures that aren’t high enough to trigger a shut-off, but doing so can reduce equipment life. Humidity levels and airborne contamination can impede performance, too. For data center owners, developers, and operators, the high cost of cooling is especially problematic. As Pacific Gas & Electric explains in its Data Center Best Practices Guide, data centers can consume 100 to 200 times as much electricity as standard office spaces. Continue reading

  • HVAC Maintenance and Replacement Parts: Custom Seals, Gaskets, and Insulation

    HVAC MaintenanceHVAC maintenance, repair, and overhaul (MRO) organizations need replacement parts for air handling units, air conditioners, boilers, chillers, heat pumps, furnaces, humidifiers, dehumidifiers, and other types of HVAC equipment. HVAC MROs also need to source these replacement parts in low-to-medium volume quantities that meet requirements for cost and quality.

    HVAC original equipment manufacturers (OEMs) can supply rubber seals, gaskets, and insulation, but at higher prices and in greater minimum order quantities (MOQs) than some HVAC MROs want to pay. HVAC aftermarket parts are available, but commodity items aren’t the right choice when a custom sealing and insulation solution is required.
