Improved side wall plate members for an adjustable width, continuous casting mold. The adjustable width continuous casting mold is formed of a pair of opposed, spaced apart front and rear mold wall members and a pair of opposed, spaced apart side wall members with the side wall members clamped between the front and rear mold wall members. The improved side wall members of the present invention prevent scratching and wearing of the surfaces of the adjacent front and rear mold walls during mold width adjustment and also prevent twisting or tilting of the mold wall side members during such adjustment. Furthermore, the improved side wall members avoid the formation of flash producing gaps or spaces at the corners of the mold. Each sidewall member according to the present invention, includes, along its side edges, i.e., the edges in contact with the adjacent front and rear mold wall members, a bearing surface formed of a low friction, thermally stable, compressible, memory material. The bearing surface is preferably an insert positioned in a socket or groove within the side edge of the side wall member. The bearing surfaces or inserts are compressed when the mold cavity is clamped together so that the side edges of the side wall members are in contact with the front and rear mold wall members. When it is desired to adjust the width of the mold cavity, the inserts expand beyond the side edges of the side walls into contact with the adjacent front and rear mold wall members.
