Abstract
Methods of manufacturing honeycomb-structure-forming extrusion dies having a number of slots for use in producing extruded articles having complex honeycomb patterns and extrusion dies for use in the manufacture of extruded honeycomb bodies. The method includes inserting a die insert having a runner and a number of teeth into a slot of an extrusion die such that each of the teeth blocks at least a portion of the slot of the extrusion die. The method further includes separating the runner from the teeth so that the teeth remain within the slot of the extrusion die.
Claims22
A method of manufacturing a honeycomb-structure-forming extrusion die, comprising:
- inserting a die insert comprising a runner and a plurality of teeth extending from the runner into a slot of an extrusion die such that each of the plurality of teeth blocks at least a portion of the slot, wherein the extrusion die comprises a plurality of pins defined by a first plurality of slots extending in a first direction and a second plurality of slots extending in a second direction disposed at an angle to the first direction;
- and separating the runner from the plurality of teeth such that the plurality of teeth remain within the slot of the extrusion die, wherein inserting a plurality of teeth of the die insert into a slot of the plurality of slots such that the slit of each of the first plurality of teeth is arranged at an intersection of two slots.
A method of manufacturing a honeycomb-structure-forming extrusion die, comprising:
- inserting a first die insert into a first slot of a first plurality of slots of the extrusion die, wherein the extrusion die comprises a plurality of pins defining a grid pattern formed by the first plurality of slots that extend in a first direction and a second plurality of slots that extend in a second direction arranged at an angle to the first direction, such that each tooth of a first plurality of teeth of the first die insert blocks a portion of the first slot, the plurality of teeth extending from a first runner of the first die insert;
- separating the first runner from the plurality of teeth of the first die insert;
- inserting a second die insert into a second slot of the second plurality of slots such that each tooth of a second plurality of teeth of the second die insert blocks a portion of the second slot, and such that a tooth of the second plurality of teeth of the second die insert mates with a tooth of the first plurality of teeth of the first die insert, the second plurality of teeth extending from a second runner of the second die insert;
- and separating the second runner from the second plurality of teeth of the second die insert, wherein inserting the first plurality of teeth of the first die insert into a slot of the plurality of slots such that the slit of each of the first plurality of teeth is arranged at an intersection of two slots.
