Bonded Gaskets for Sealing and Insulation

Better bonded gaskets improve quality and perceptions of quality. They reduce labor costs and support sales, too.

Bonded Gaskets

Finished gaskets need strong bonds to provide reliable sealing and insulation. In applications where rubber gaskets are visible, bonds that look better also suggest higher product quality. Buyers of specialty vehicles, commercial ovens, and electrical enclosures (just to name a few) don’t want to see bonded gaskets that look like they’re ready to pull apart in the corners or that need touch-ups.

Even in applications (such as HVAC systems) where finished gaskets are hidden, failure is expensive. Replacing the rubber seal in an air conditioning unit may cost more than you realize. In addition to paying for a replacement part, there are direct labor costs. Indirect costs including traveling to and from the job site, scaling ladders, pulling and replacing panels, and completing paperwork. Over time, it all adds up.

Gasket bonding may seem simple, but it’s skilled labor. You can buy your bonded gasket equipment, but machines don’t come with expertise. Even in an age of digital manufacturing, some activities still require craftsmanship. Plus, some bonding methods require cuts that you don’t have the equipment to make. You can try using guillotine saws or hand tools, but you can’t match water jet cutting. (more…)

Seal Rounded Corners by Starting with These Three Measurements

Seal Rounded Corners with Bulb Trim Seals Do you need to seal rounded corners against wind, water, dust, or dirt? Bulb trim seals are industrial rubber products that provide sealing and insulation for machine doors, vehicle hatches, and equipment enclosures. They’re designed to seal rounded corners and have separate bulb and retainer sections. Each of these sections can use a different material and have a different durometer or hardness.

With bulb trim, the bulb section compresses to form a seal when the door, hatch, or enclosure is closed. The trim or retainer section attaches to a flange or substrate. To choose bulb trim for your application, you need to specify the bulb size, bend radius, and flange thickness. By choosing the right bulb size, you can avoid over-compression. The right bend radius and flange thickness help to avoid kinking and leakage. (more…)

What’s in the Elasto Bag? Sealing and Insulation Samples for Mobile Equipment

elasto bagDo you need thermal, acoustic, or thermal-acoustic insulation for forestry, mining, construction, or other types of mobile equipment? Maybe you need cabin flooring or floormats instead. The Elasto Bag, a sack full of samples from Elasto Proxy, contains sealing and insulation that you can see for yourself and hold in your hands. It’s easy to request an Elasto Bag, but what’s inside when you get it?

The Elasto Bag contains at least nine samples of sealing and insulation. (We can also include samples of  edge trim, bulb trim, or D-shaped profiles with adhesives if you need them). Let’s take a look at what’s inside the Elasto Bag so that you’ll understand what you have or can get. Along the way, you’ll see links where you can download product specifications. (more…)

Cold Bonding vs. Injection Molding for Rubber Gaskets

Finished Gaskets - BlogCold bonding for finished gaskets joins cut lengths of rubber without the use of heat. This bonding technique isn’t performed under low-temperature conditions but is manual process that requires a brush and glue. By contrast, injection molding is a semi-automated process that uses a C-press machine with a heated barrel, metal plates, and tons of pressure. To join cut lengths, uncured rubber is used.

By understanding how these joining processes work, engineers can make better decisions about which types of finished gaskets to choose. It’s also important to understand the advantages of disadvantages of each bonding technique. In this week’s article, we’ll compare cold bonding with injection molding in terms of capabilities, costs, and quantities. (more…)

Hot Splicing vs. Vulcanizing for Rubber Gaskets

Bonded GasketsHot splicing uses heat, pressure, and a film splice to join the ends of rubber profiles into bonded gaskets. This joining technique uses either a conventional heating source or infrared (IR) light and polyethylene (PE) film. Hot splicing creates strong bonds at the molecular level and generally provides better results than vulcanization, a bonding technique that uses uncured rubber instead of a film splice.

Choosing the best way to bond rubber gaskets can be a complex decision, however. The profile material is just one of many considerations. You also need to consider the size and shape of the seal, production quantities and costs, and the way that lengths of rubber are cut. In addition, it’s important to inspect and install your gaskets properly to ensure reliable sealing and prevent avoidable waste.

Is hot splicing better than vulcanizing for the rubber gaskets that you need? Let’s take a closer look. (more…)

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…)

Rubber Floor Mats Reduce Wear, Danger, and Noise

Rubber Floor MatsRubber floor mats for mobile equipment protect cabin floors from damage and operators from slip-and-fall hazards. Rubber flooring that’s laminated to acoustic insulation also absorbs noise from the engine compartment, which is often directly below the cab where the operator sits. Rubber matting can even be used as a kick-plate to protect cabin walls from contact with an operator’s boots.

For mobile equipment manufacturers, choosing the right type of cabin flooring is an important design consideration. The metal floors that are used inside a cab are durable, but operators track mud, snow, dirt, and water inside. Rubber floor mats can protect these metal surfaces from rust, corrosion, and scratching. Sheet metal flooring can become slippery, but rubber surfaces can offer surer footing.

As manufacturers are discovering, rubber floor mats are part of a complete cabin solution that promotes operator safety and equipment performance. By understanding how rubber flooring is designed and made, manufacturers can determine if a custom-fabricated solution is the right choice. For starters, however, engineers may want to compare rubber to other flooring materials. (more…)
