摘要： The present disclosure relates to a method and an extrusion apparatus (100, 200) to manufacture a soot preform (130). The extrusion apparatus (100 and 200) includes a feed-hopper (104) to feed silica slurry (102) which is pushed within the barrel (106), an iris frame (116) exhibiting a variable diameter to control a diameter of the soot preform (130), drying furnace (118), debinding furnace (122) eliminates moisture and one or more stabilized binders in the soot preform (130) to obtain a glass preform (138) from which an optical fiber (142) is drawn.
