TISA is responsible for making the front and slide (rear) door panels

 

for the Toyota Sienna minivan. The main components of

 

the door panels are fabricated using an injection molding process.

 

Other processes include: ultrasonic welding

 

and vacuum forming. The door panel also includes

 

a speaker grill that is molded into the front door panel

 

during the injection molding process. An optional feature that is

 

sometimes included is the sunshade for the slide door.
