Flat film extrusion die |
| abstract |
Flat film plastic extrusion die, which may be in the form of either a single slot or dual slot die. A body part forms the top of the die and has sloping side walls converging from their upper towards their lower ends. The body part may be in two parts divided by a divider where the die is a dual slot die. Die heaters form the closures for the melt chamber of the die and clamp thin metal liner sheets to the sloping sides of the body part by through bolts clamping the die heaters to the body. The sheets form the liner wall of the melt chamber and are sufficiently thin that pressure in the die chamber will conform the sheets into intimate contact with the inner walls of the heaters. The lower ends of the sheets depend into recessed portions of the heaters and form die lips. The die lips may be formed by the depending sheets or may extend along relatively thick silver soldered strips to define deckle lands at the lower ends of the sheets. Adjustment screws threaded in the die heaters are provided to adjust the space between the lands, or between the lands and a center divider where the die is a dual slot die. |
