Method for forming a combination door and window channel seal

A method for forming a combination door and window channel seal for a motor vehicle, the method comprising:

• molding thermoplastic elastomers of at least two different durometer values to form a door and window channel seal in a one-piece generally U-shaped configuration so that a corner of a window channel section of the seal has an elastic strip of increased flexibility disposed between adjacent strips, the elastic strip of a more elastic material than the adjacent strips, the window channel section adapted to receive a resilient window engaging sealing insert to contact a glass panel.

A method for forming a combination door and window channel seal for a motor vehicle, the method comprising extruding thermoplastic elastomers of at least two different durometer values, one of the thermoplastic elastomers being of a greater elasticity, to form a door and window channel seal in a one-piece generally U-shape configuration having an elastic joint strip of the greater elasticity thermoplastic elastomer intermediate a pair of strips formed of thermoplastic elastomer of less elasticity, the generally U-shape configuration of the door and window channel seal adapted to receive and retain a resilient window engaging sealing insert.

• and
• inserting a resilient window engaging seating insert into the window channel section.

A method for forming a combination door and window channel seal for a motor vehicle, the method comprising

• extruding thermoplastic elastomers of at least two different durometer values, to form a door and window channel seal in a one-piece frame having a first generally U-shape window channel section for operably receiving a resilient window engaging sealing insert and a second generally U-shaped flange engaging section, the window channel section having an elastic joint strip of a first durometer intermediate a pair of strips formed of a higher second durometer material;
• and
• inserting a resilient window engaging sealing insert into the window channel section.
