Tooling Change Generates 350-Percent Productivity Increase
Recently, the firm experienced excessive tooling wear when stamping the bandolier or carrier strip to support the electrical contact. Presses were running at speeds of 1200 strokes/min., yielding 17 coils—at 100,000 parts per coil—before the tooling needed to be sharpened. Production manager Larry Rehak turned to tool-steel supplier General Carbide, Greensburg, PA, to help engineer a solution, which came during the third quarter of 2009 when IMF switched to General Carbide’s GC-813CT bi-modal tooling made with additions of chromium carbide and tantalum carbide.
General Carbide produces tungsten carbide preforms and blanks used for wear, cutting and metalforming operations. GC-813CT (rated to a hardness of 90.5 to 91.5 HRa), reports Rehak, has reduced corrosion and galling, and has enabled IMF to run as many as 65 coils per tool sharpening and experience a 350-percent productivity increase. With its previous tooling, IMF changed tooling once each day; now, tools remain in the press for four days. GC tooling now runs in three IMF presses.
