Title:
GASKET AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/091685
Kind Code:
A1
Abstract:
A method for producing a gasket comprises a step for ejecting liquid curable resin
onto the surface of a cover body (12) and semi-curing the resin by UV-irradiation
(formation of a first layer (10A)). Subsequently, liquid curable resin is ejected
onto the semi-cured resin (formation of a second layer (10B)) and then the first
layer (10A) and the second layer (10B) are fully cured. Since the first layer (10A)
is semi-cured, it does not collapse under the weight even if the second layer (10B)
is stacked thereon by ejecting the curable resin, and the profile after ejection
can be sustained. Consequently, a gasket (10) having a small line width, a high
profile, and a high dimensional precision is obtained on the surface of the cover
body (12). A method for forming a high-profile gasket is provided by a dispensing
method.
