Cold Bonding vs. Injection Molding for Rubber Gaskets
Cold 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 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.
Rubber 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.
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.
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.
Window channels are rubber gaskets that hold window glass in place and help to secure window frames. They also eliminate rattling and provide protection against wind, water, dust, and debris. Applications for window channels include mobile equipment, defense, medical and health, stainless steel and food equipment, infrastructure, and aerospace.
Industry 4.0 is a catchphrase and buzzword that you can no longer afford to ignore. This fourth phase of the Industrial Revolution isn’t just about the increased digitization of manufacturing. It’s not just about advances in automation either. Industry 4.0 could change how your company competes and whether or not you’ll continue to win. Industry 4.0 isn’t just about technology. It’s about profitability.
There are four common shapes for extruded rubber seals. Do you know which shape is the right choice for your gasket application? Engineers and seal designers can choose P-shapes, D-shapes, E-shapes, and lip seals. Purchasing agents can either order cut lengths or buy spliced gaskets.
Bulb trim provides sealing and insulation for doors, hatches, and enclosures with rounded corners. These industrial rubber products have separate bulb and retainer sections, each of which can have a different durometer or hardness. The bulb forms a seal under low-to-medium closure force. The retainer or trim is pressed into place over a flange and may have an integral tongue or metal clips to promote attachment.
Elasto Proxy supplies industrial products that you probably didn’t know we offered. Why does this matter to you? Engineers need reliable parts that support larger product designs. Components that don’t work, won’t fit, fail in the field, or wear out too soon can cause project delays and cost overruns. If your current supplier can’t support your application, Elasto Proxy may offer an alternative.
