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.
Claims16
A method of forming a seal on a vacuum bag used in an infusion molding process, the method comprising:
- securing a seal profile having a first part and a second part to a supporting surface;
- applying a first resin to the seal profile to form a mold layer;
- removing the mold layer and the seal profile from the supporting surface;
- separating the second part of the seal profile from the first part of the seal profile;
- and
- applying a second resin to the mold layer and the first part of the seal profile to form the seal on the vacuum bag.
A method of forming a vacuum bag for use in an infusion molding process using a plug flange defining a flange seal profile as a cavity, the method comprising:
- inserting a filler into the cavity in a bottom portion of the cavity;
- and
- applying a resin over the plug flange, flange seal profile, and filler to form a seal on the vacuum bag.
A method of forming a vacuum bag and a seal on the vacuum bag for use in an infusion molding process, the method comprising:
- providing a seal profile on a supporting surface;
- assembling a seal profile filler to a bottom portion of the seal profile;
- and
- applying a resin to the seal profile, the seal profile filler, and the supporting surface to form the vacuum bag and a seal on the vacuum bag.
