Ideas to improve seal and gasket assembly

During the design process, a number of manufacturing methods can be explored to improve the final installation of a seal or gasket. 

New Call-to-actionCustom plastic extrusions provide several opportunities to improve gasket design. 

A rigid plastic extrusion can be affixed to a rubber seal, allowing it to be securely attached in the final assembly.

Another option is to use flexible plastic to grip onto a component while adhesives or other fasteners are applied.  

Lauren's iDea Seal product line features EPDM seals that are bonded to a rigid plastic base that easily slides into a channel.  

Co-extruded plastics deliver a mix of material properties, which can meet requirements for achieving an effective seal while supporting installation needs. A dual-durometer rubber extrusion also can be used in a similar manner.  

Other mechanical fastener options include push pins or plastic rivets. 

Pressure sensitive adhesives and heat activated tape provide a variety options for gasket assembly. Discontinuous lamination allows tape to be applied only in specific locations on a part.  

Assembly-aid coatings are a cost-effective way to improve installation processes for rubber parts. Applied during extrusion, coatings can reduce friction when a part is inserted into a kerf or channel.  

By installing a gasket as a single component, manufacturers may be able to eliminate the need for splice joints.  This can improve efficiency while preventing potential leak points. Continuous corner seals, molded end details or molded frames can be used for this purpose.
