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.
