Methods of manufacturing a die body

Provided is a method of making a die body (113) configured to extrude a honeycomb body, the method comprising the step (I) of manufacturing a die body (113) and the step (II) of predetermining an upstream slot width (W1) of the die body (113) such that the upstream slot width (W1) is optimized while...

Zusammenfassung:	Provided is a method of making a die body (113) configured to extrude a honeycomb body, the method comprising the step (I) of manufacturing a die body (113) and the step (II) of predetermining an upstream slot width (W1) of the die body (113) such that the upstream slot width (W1) is optimized while a root (313) of each die pin (205) includes a section modulus within a predetermined section modulus range. The method still further comprises the step (III) of predetermining a slot length (L) such that a pin stress is within a predetermined pin stress range.
