EXTRUSION – SPLICING
Pro-Flex has been producing quality extruded rubber products for the mass transit industry and other industries for over 10 years. We can custom cut and splice extruded profiles in a variety of ways to meet all of our customer’s needs.
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 considerations are the physical integrity of the joint. There are three types of splicing:
COLD SPLICINGThis process is less expensive depending on the complexity of the cross section and design of the seal. It is fast and strong but can be brittle. The splice seal will also have different properties than the sealed material. Most of the time no tooling is required, therefore cost is kept to a minimum. |
HOT SPLICINGThis is the industry's standard and is most desirable when cosmetics are a concern. In hot splicing the glue is a rubber-based and needs to be vulcanized in place. The process may take longer than cold splicing depending on the cross section. This process requires some tooling costs for the curing process |
INJECTION SPLICINGA 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 . The process allows for much greater detail work on the seal. This method often requires more intrecate tooling, which can also be expensive. |
