Rubber extrusions language of rubber
Rubber profiles are made either through continuous extrusion and vulcanisation - LCM , UHF etc. - or discontinuous by extrusion and autoclave (steam) vulcanisation. Both methods have their specific advantages and limitations. Our production centres use both methods. Customers are always asked for the application of a rubber profile so all ins en outs of the profile can be taken into account in the earliest possible stage of development.

Extruded rubber sections can be converted into continuous rubber frames and rings.
Glueing and cold vulcanisation
Cold vulcanisation is creating a seal by glueing of two or more rubber sections. Daarbij wordt gebruik emaakt van snelle lijmsoorten zoals cyano-acrylate of rubberlijm. This method is quick and cheap, joints however are not as good looking as spliced joints and may be brittle. The main disadvantage is the fact that because of different materials in sections and glued areas the joints respond differently to temperatue changes.This may cause premature failure
Splicing of extruded rubber sections show very nice results. The actual joining of the sections is made possible by a special rubber based substance during vulcanisation. This method allows for joints that share the properties of the extruded sections and that are barely visible. Special moulding tools are required.
Injection and compression joints
Injection en compression joints are made in moulds. Two sections of extruded profiles are stuck in a mould that is filled witha certain amount of elastomer by injection injected or by putting in the precisely measured amount of elastomer. During vulcanisation both ends of the sections are joint. This proces is used for the production of large series and result in very good looking joints. Special moulding tools are required speciale lasvormen noodzakelijk.

Self adhesive rubber profiles
Self adhesive backing of rubber seals can speed up assembly considerably. Ligther weight rubber profiles can even be permanently fixed with special self adhesive tapes. Likon can supply you rubber sections with types of self adhesive tapes.
