Abstract: A method is disclosed for forming a seal on a vacuum bag used in an infusion molding process. A seal profile having a first part and a second part is attached to a supporting surface and resin is applied to the seal profile to form a mold layer. The mold layer and the seal profile are separated from the supporting surface. The second part of the seal profile is separated from the first part of the seal profile. A silicone resin is applied to the mold layer and the first part of the seal profile to form the seal and the vacuum bag. A vacuum cavity is created between the mold layer and the second resin when the second resin is applied to the first part of the seal profile.

Abstract: A seal is provided on a vacuum bag used in an infusion molding process. The seal is a truncated V-shape that has convergent walls and a distal end that defines a vacuum channel in conjunction with an infusion mold.
