What’s the Best Way to Bond Rubber Gaskets?
658136 What’s the Best Way to Bond Rubber Gaskets? Rubber profiles come in lengths that are cut-to-sizeand 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. Hot Splicing Hot splicing uses heat, pressure, and a thin PE film splice to join the ends of rubber profiles. This bonding technique is called “hot” because it uses either a conventional heating source or infrared light (IR). Traditional splicing takes longer than IR splicing, but both methods create strong bonds. Most film splices are 90°, but hot splicing also supports 45° miter cuts and endless gaskets. Hot splicing requires clean, straight cuts but supports higher production volumes. The type of profile usually determines whether a conventional heat source or IR light is used. IR splicing is a good choice for sponge rubber profiles because IR won’t burn the elastomer. IR splicing can also accommodate larger profiles and requires less post-production trimming. With silicones, however, traditional splicing is used. Vulcanization Vulcanization uses heat, pressure, and uncured rubber that’s made of the same elastomer as the profile itself. Compared to hot splicing, this bonding technique is more forgiving since the cuts don’t have to be smooth and precise. With vulcanization, uncured rubber is applied to the profile’s ends. After the ends are pressed together, the joint is placed into a hot mold. Applications for vulcanization include O-rings, tubing, and other industrial rubber products with a space for the free-flowing passage of air to the gasket. Vulcanization can’t match hot splicing in terms of results, but vulcanized seals and gaskets are good for low volumes. Cold Bonding Cold bonding is a manual process that’s performed with a brush and an adhesive or glue. This technique is called “cold” because no heat is applied to the ends of the gasket. Bonding systems include low, medium, and high viscosity adhesives in cyanoacrylate, silicone, and epoxy formulas. Glues may be designed for specific types of rubber or crystalize when they contact water. Cold bonding or gluing doesn’t require metal tools called dies, but cold bonded gaskets won’t last as long as hot spliced ones. Plus, cold bonding is more expensive than hot splicing. Compared to molding, however, cold bonding costs less because there’s no metal tooling. Gasket fabricators can add labor to projects, but most cold bonded gaskets are produced in low-volume quantities. Molding Molding is the only bonding technique that can create rounded corners for rubber gaskets. This joining method is also recommended for gaskets with corners that will be stretched or pulled. Compared to hot splicing, molding produces stronger joints and offers increased resistance to leaking. Molding is also recommended for bulbs with difficult shapes. Molded gaskets require tooling and C-press injection molding equipment. The cost of a metal mold can be significant, but tooling that’s used across higher volumes of gaskets has a lower unit cost. Molding is generally used with larger production runs; however, molding is not recommended for silicone or sponge profiles. Get the Sample Kit Elasto Proxy is a gasket fabricator that provides a choice of joining methods. Our capabilities include hot splicing, vulcanization, cold bonding, and molding.

Rubber Floor Mats
Rubber Floor Mats Reduce Wear, Danger, and Noise Rubber 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. Rubber Floor Mats vs. Fabric Carpeting In a mobile equipment cabin, an operator’s feet may stay in the same position for long periods of time. With carpet floor mats, heel wear can create holes that expose the subfloor, introducing a potential safety hazard and providing a path for engine sounds. Plus, unlike carpeting, rubber floor mats won’t stain. Rubber is also easier-to-clean and provides greater wear-resistance. Rubber flooring is usually black, but mobile equipment manufacturers can choose colors such as gray or brown instead. Custom colors that complement larger product designs are also available. Some rubber is smooth, but floor mats and flooring can have a pebbled texture instead. Rubber floor mats can also have recessed, diamond-shaped features to catch the dirt, mud, snow, or water from an operator’s boots. Fabric carpeting absorbs sounds, but rubber flooring is part of a complete noise-control solution. In mobile equipment, rubber floor mats can be laminated to acoustical foams that are typically 3/8” or 5/8” thick. These foams can absorb or dampen loud sounds and even tune-out specific frequencies, such as the low-frequency rumble of a large diesel engine. Custom-Fabricated Rubber Flooring Rubber flooring that’s custom-fabricated can save mobile equipment manufacturers time and money. Cutting rubber sheets with hand tools is time-consuming and may result in significant amounts of material waste. If an employee tosses a poor-quality cut into the trash, managers may never know how much rubber flooring a job actually used. Custom-fabricated flooring that’s water jet cut uses a form of digital manufacturing that works directly from an engineer’s CAD files. For the rubber flooring that’s near the driver’s seat, water jet technology cuts precise openings for the arms that attach to gas and brake pedals. Water jet cutting can also produce bolt-holes for flooring near seats and smooth edges for where rubber kick plates meet cabin insulation. The lamination that’s used with rubber flooring also involves skill, speed, and precision. By combining layers of different materials into an “insulation sandwich”, a custom fabricator can deliver rubber flooring that meets all of a project’s requirements. A complete sealing and insulation like this can absorb sounds, protect metal subfloors, and reduce slip-and-fall hazards inside the cab. How to Choose Rubber Floor Mats Elasto Proxy custom-fabricates rubber floor mats for mobile equipment. In addition to water jet and abrasive water jet cutting, we provide lamination services.

Custom Cab Insulation
Hey Everyone! We want to educate our listners on various subject so we decided to start off with the following: Custom Cab Insulation Reduces Sound, Costs, and Mistakes Custom cab insulation absorbs sound and provides a finished appearance to mobile equipment interiors. This acoustic insulation can be cut by hand and applied with spray adhesives, but that process is expensive, wasteful, and even hazardous to human health. Plus, manual cutting can result in cabin insulation that’s unappealing. Buyers who see mis-cuts may question the quality of your overall equipment design. As mobile equipment manufacturers are discovering, there’s a better way to design and build quieter cabs. Custom-fabricated insulation that’s waterjet cut creates straight lines and chamfered angles. There’s less material waste, reduced cutting times, and closer control of material usage. Engineers can also get design assistance and help with material selection. Installers can avoid messy, toxic spray adhesives. Parts marking, kitting, and packaging provide benefits, too. By taking a closer look at how custom-fabricated cab insulation is made, you can determine if it’s the right choice for your company. Design Assistance and Material Selection Engineers are experts in their fields but may be pressed for time across multiple projects. An insulation fabricator who offers design assistance can serve as an extension of your engineering team. The right manufacturing partner can also help with material selection. Typically, cab insulation like headliners, door panels, and side panels are made of perforated vinyl foams that are between 1/2” and 1” thick. Material type and thickness aren’t the only design considerations. In a crowded marketplace, mobile equipment manufacturers need distinctive products. Custom cab insulation can match your color scheme and have a basket-weave pattern or texture. Perforated vinyl foams come standard in black, gray, and Mojave brown, but custom-color matching is available. Some foams even have a metallic finish. Water Jet Cutting Some mobile equipment manufacturers still cut cabin insulation by hand. Typically, installers use a cardboard template and a utility knife or box cutter. Manual cutting might seem less expensive than water jet cutting, but poor-quality cuts can produce significant material waste. If installers toss mis-cut insulation into the trash, managers may never know a job’s true material usage. Water jet cutting lets you buy only the material that you need. Plus, because it’s automated, water jet cutting is repeatable. Unlike an installer who makes the right cut in the morning and the wrong cut in the afternoon, water jet technology produces the right cut every time. There are no templates or hand tools either. Water jet cutting uses your CAD files and is a tool-less technology without blades that get dull. Quality improves, too. Water jet cutting can create smooth, straight lines or chamfers with 30° or 45° angles. Angled cuts for wrap-around edges provide a finished appearance. Through-holes for fasteners support the use of fire extinguishers, net pockets, first-aid kits, and other cabin components. Blind holes in the back of the cab insulation are hidden from occupants and support flush mounting. Taping Mobile equipment manufacturers who install cab insulation by adhesive spraying face several challenges. These companies need to comply with health and safety regulations and perform time-consuming setup and cleanup activities. If the adhesive is wrong for the application environment, the insulation may peel away from the cabin and require rework or repairs. Custom cab insulation that attaches with pressure-sensitive adhesive (PSA) tape offers an alternative. Whether on the assembly line or in the field, an installer peels away the backing material and attaches the insulation to the cabin surface. For headliners, PSAs that support heavier weights are available. Insulation fabricators can also suggest PSA tapes for specific temperatures and humidity conditions. Parts Marking, Kitting, and Packaging Parts marking, kitting, and packaging can also save mobile equipment manufacturers time and money. Inkjet printing and UV drying produce parts with letters and numbers that are easy-to-read for fewer picking errors. Parts that are kitted and packaged into a single box also speed assembly times. Instead of looking for different SKUs in a warehouse, an installer can just open the package and get to work. #elastolife #customdesign #supplychain www.elastoproxy.com

CANSEC Interview with Paul Turner from Scepter
Hey Everyone! Here's an interview with Paul Turner from Scepter which we met at CANSEC 2018. Scepter Started almost 60 yrs ago in the manufacturing of inflatable vinyl toys Scepter grew quickly,. In the early days, Scepter made everything from inflatable toys to wading pools, hula hoops, and a wide range of consumer goods. But our founder believed many industrial needs could also be met with plastics. Scepter had set the stage for its current reputation as an innovator by blow-moulding the first plastic Jerry Gas Cans in Canada in the late 1950s. By the end of the first decade, the plant had doubled in size, and Scepter had received numerous design and innovation awards from the plastics industry. #CANSEC2018 #Elastolife www.scepter.com www.elastoproxy.com

Dr. Paulo Arruda and acoustics!
Hey everyone! This week's podcast is a liitle longer than usual. We expected it seeing that we had Paulo on! The topic we chose is on acoutics, basically going a little deeper than what our blogs cover. By the way you can check out our blog at www.elastoproxy.com Acoustic 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.
