Infrared splicing isn’t the same as hot splicing, but both joining techniques offer advantages. Which splicing technique is right for your custom rubber gaskets – and how do these film splicing methods compare to cold bonding?
Splicing joins lengths of extruded rubber to create elastomeric products such as hollow O-rings, low-closure force seals, and large-diameter profiles that are too expensive to mold. Splicing methods vary, and choices include film splicing, cold bonding, C-press injection molding, and vulcanizing. By working with an experienced gasket fabricator, you can select the right splicing technique for your application.
Each splicing method offers advantages, but film splicing creates strong bonds without adhesives. This joining method also supports fast cycle times and creates strong corners that won’t crack. Film splicing isn’t new, but it’s important to understand how infrared splicing compares to traditional hot splicing. For larger seals, more durable splices, and an alternative to molded parts, IR splicing is a strong choice. (more…)
