An extrusion die for forming an extrudate, the extrusion die comprising: a first die body having a first lip, a second die body having a second lip, said second lip positioned opposite and adjacent to said first lip, a gap extending in a first direction from said first lip to said second lip, said gap also extending in a second direction perpendicular to said first direction; and a lip adjustment assembly (100, 200) mounted to said first die body and configured to adjust the position of said first lip relative to said second lip to thereby adjust a thickness of said extrudate that exits said gap, said lip adjustment assembly (100, 200) having a working end adjacent to said first lip, an exposed end opposite to said working end, and a translating unit between said exposed end and said working end, said translating unit configured to move said working end to adjust the position of said first lip, said translating unit having a translator, a mounting member coupled to said translator, and a rod having a central axis and that is coupled to said mounting member, said translator being fixed with respect to said rod, said mounting member configured to be accessible from said exposed end to decouple said translator from said rod so that said translator is removable from said lip adjustment assembly (100, 200), wherein said lip adjustment assembly (100, 200) includes a rotation inhibitor coupled to said translator and said rod, said rotation inhibitor configured to inhibit rotation of said rod about said central axis, characterized in that said mounting member removably couples said translator to both said rotation inhibitor and said rod. a first die body having a first lip, a second die body having a second lip, said second lip positioned opposite and adjacent to said first lip, a gap extending in a first direction from said first lip to said second lip, said gap also extending in a second direction perpendicular to said first direction; and a lip adjustment assembly (100, 200) mounted to said first die body and configured to adjust the position of said first lip relative to said second lip to thereby adjust a thickness of said extrudate that exits said gap, said lip adjustment assembly (100, 200) having a working end adjacent to said first lip, an exposed end opposite to said working end, and a translating unit between said exposed end and said working end, said translating unit configured to move said working end to adjust the position of said first lip, said translating unit having a translator, a mounting member coupled to said translator, and a rod having a central axis and that is coupled to said mounting member, said translator being fixed with respect to said rod, said mounting member configured to be accessible from said exposed end to decouple said translator from said rod so that said translator is removable from said lip adjustment assembly (100, 200), wherein said lip adjustment assembly (100, 200) includes a rotation inhibitor coupled to said translator and said rod, said rotation inhibitor configured to inhibit rotation of said rod about said central axis, characterized in that said mounting member removably couples said translator to both said rotation inhibitor and said rod.
