Extrusions are continuously produced lengths of material forced through a profiled die in an infinite variety of shapes. We offer a vast range of profiles in a very wide range of materials. We are able to offer extrusions in both conductive and non-conductive grades, as well as sponge materials

Log Cutting

Here at RFI Seals & Gaskets (An Advanced Seals & Gaskets Ltd group company) we have over 30,000 Square feet of manufacturing facilities which possesses a wealth of manufacturing capabilities including Log Cutting. This process is able to produce Log Cut strip products in either plain or self adhesive backed formats and widths starting from 4mm to over 1metre in any increment between. We have a Full Log Cutting section built up from state of the art CNC Controlled machinery from the worlds leading manufacturer of Log Cutters CMC Cevenini.


When you require a 3 dimensional component, the most common and probably best known is moulding which has 2 main areas. The first area is compression moulding, which is most frequently used on lower volume or larger sized components. The second, is injection moulding, which is more suited to high volume smaller components.

Printed Gasket Component Technology

The process of printing Conductive and Non-conductive elastomers is a novel and very cost-effective method of producing gaskets. The printed process produces a highly selective deposit resulting in negligible wastage.

Gaskets can be printed onto a carrier (e.g. metal or plastic) to ease assembly and location. The gaskets can be printed direct onto a component, greatly improving assembly and secondary environmental seals can be incorporated into a gasket.

Punching / Stamping

Our most common form of Gasket production is by punching or stamping two-dimensional components from sheet or strip material.
We are capable of producing from thin foils to thick sponges in simple rectangular gaskets through to complicated manifold type gaskets. We can also produce square section rings and washers by slicing, or parting from tube or extrusion.

Water Jet Cutting

This process utilises a jet of water pressurised to 30,00090,000 psi (210–620 MPa) that is then forced through a nozzle to produce a jet of water thinner than a human hair. In a pure water form this can cut rubbers, plastics, sponges, paper and many other materials to many millimetres thick extremely accurately. With introduction of an abrasive powder, it is capable of cutting Steels, Titanium, Inconel and other metals, as well as composites like Carbon Fibre. With the advantage that with extremely localised heat generation it produces zero or minute blackening on the cut edge.

Water cutting has tremendous advantages over traditional manufacturing methods when dealing with thick rubbers and sponges, or when ultra accurate or complicated gaskets are required. It also comes into it’s own when customers are developing new products and require one’s and two’s of different components, as it doesn’t require tooling. Infinite variations on dimensions are possible with a few simple keystrokes at the processor controller.
