    manufacturing the surface area of each jaw member to fall within a specified manufacturing range;

    manufacturing the distance from a pivot of each jaw member to a centroid of a sealing surface of each jaw member to fall within a specified manufacturing range;

    manufacturing the angle between a cam slot of each jaw member and a line perpendicular to the sealing surface of each jaw member to fall within a specified manufacturing range;

    manufacturing the distance from the cam slot to the pivot of each jaw member; and

    a width of the cam slot of each jaw member to fall within a specified manufacturing range;

    providing a spring with a known spring constant and a known free length;
