Designed for applications that require a continuous seal, from a multi-sided product to a simple o-ring.

Typically, welds are much more durable than simple splices when used for thermoplastic materials that must withstand tremendous pressure on the joint. Across the board, our capabilities support cold and hot splicing as well as transfer and molded splicing.


Splicing is used when an application requires a continuous seal, such as a multi-sided frame or an o-ring. When designing a spliced seal, the key consideration is the physical integrity of the joint.

Cold Splicing

Simply a matter of gluing two or more pieces of a seal together using quick-setting glue such as cyano-acrylate or super glue. Cold splicing is generally less expensive, depending on the design of the seal and the complexity of the cross section. There are few, if any, tooling costs.

Hot Splicing

Considered to be the industry standard and most desirable when cosmetics are a concern. The glue used in hot splicing is rubber-based and has to be cured, or vulcanized, in place. This creates a splice that has reasonable strength, retains properties of the seal, and is inconspicous.

Injection Splicing

Works similar to injection molding. A mold is created so that two or more pieces of a seal can be inserted into the tooling. A polymer is then injected or transferred into the mold cavity, adhering the ends of the seal and creating a continuous o-ring or multi-sided gasket. The process allows for much greater detail work on the seal, producing a splice that is aesthetically pleasing.
