Patent #'s 10525627 and 10220559
Our shaped gasket dispensing process, which we developed in 2006, has opened a wealth of new possibilities in manufacturing, allowing us to re-write the book on traditional gasket dispensing. Hollow and filled gaskets offer the following advantages:
1) Hollow gaskets can save 25-75% of material costs
2) Hollow gaskets provide their own compression "zones"
a) No additional provision needs to be made for elastomer squeeze-out
b) Issues with channel wall shear are reduced or eliminated
c) Compressive forces are greatly reduced
d) Compressive forces can be made to toggle the gasket profile
i) The forces can actually diminish with additional compression.
e) Compression set seems to be less pronounced in many cases
3) Materials requiring UV cure are now more efficiently cured
