EXTRUSION DIES AND METHODS AND APPARATUSES FOR FORMING THE SAME
Document Type and Number:
WIPO Patent Application WO/2016/144714
Kind Code:
A3
Abstract:
A honeycomb extrusion die (100), a method of making the same, and an apparatus for forming the same. The die (100) includes: a feed hole plate (202) comprising an input surface (202A), an opposing output surface (202B), and feed holes (108) configured to guide a batch material from the input surface (202A) to the output surface (202B); and a pin assembly (204) comprising pins (300) disposed on the feed hole plate (202). At least one of the pins includes: a tail (304); a head (302) connected to the tail (304) and comprising alignment surfaces (314) configured to align the pins (300), flow surfaces (316) disposed between the alignment surfaces (314), and a tapered portion (310) comprising a contact surface (308) adhered to the output surface (202B) of the feed hole plate (202); and a first groove (306) disposed between the head (302) and the tail (304). In the pin assembly (204), the alignment surfaces (314) contact adjacent pins (300) to align the pins (300), such that discharge slots are at least partially defined by the tails (304) of the pins (300).
