Quality of Finish, Size, Cast, Camber, Tensile, Path of Wire, Spool Sizes, and De-spooling Equipment are all major factors in how stitching wire is going to perform in the field. With the continued demand for increased run speeds and overall profit, high quality stitching wire and proper machine setup are a must. Stitching wire is a low carbon steel with a zinc galvanized or tin coating. Stitching wire is used in side stitching, saddle stitching, corner stitching, booklet making, and inline stitching in press applications.

These wires are extensively used for stitching cardboard packaging boxes/cartons/books. The wire produced goes through strict testing norms thus offering better Rust resistance properties than others.
Wire Tensile is the pull required to break the wire and is measured in pounds per square inch (PSI). The higher the breaking point, the stiffer the wire. High quality stitching wire has a tensile range of 135,000 to 165,000 PSI. A tensile above 165,000 PSI will wear out parts in your stitching head prematurely, causing maintenance costs and down time. High tensile wire can also wear out the knives in a trimmer section prematurely. The increased hardness of the stitching wire will nick a trimmer section’s knives more severely when struck during saddle stitcher jams. A tensile below 135,000 PSI will cause the stitching wire to be soft and not properly form a stitch.
High tensile stitching wires are available in the industry, but the cost benefits of using a high tensile wire with a thinner diameter on thicker applications is outweighed by the cost of premature wear on stitching heads and trimmer section knives.
