process cycle re-engineering to speed changeover between processes. This becomes increasingly important as the industry shifts to smaller lots, which require more frequent break-in sequences. Retrofit hoists, controls, and variable plate time programming eliminate guesswork and operator sensitivity associated with older simple-cycle multi- process finishing systems. 6) NADCAP & ISO quality system capable automation is assured with PC/HMI over-the-top and appropriate sensor technology monitors, controls, and records critical quality control information. Data such as tank temperatures, immersion times, rectification, pH, conductivity, barrel rotation or oscillation speed and/or duration, chemistry additions, and rinse water usage is collected and stored on a load-by- load basis. Further, data is exported to the customer data highway for upload into quality management database. This system creates truly paperless quality control. The Jessup PC/HMI system captures more data than end-user customers require. The finisher's quality control department will have access to current and historical trend data never before available. 7) Jessup cylindrical barrels can offer 17% increased capacity and 12% better work-to-anode relationship compared to hex barrels for more productive plating. More consistent anode-to-work relationship improves plating efficiency (Table 1). The drawing and comparison chart clearly illustrate capacity and work-to-anode differences. Jessup plating barrel design features include: a one-piece cylindrical shell; tongue-and-groove, double-welded construction; integrated, heat-fused tumbling ribs; CNC drilled or slotted perforation patterns for shorter drain dwells; and knob or quick-change inside-out style load-locker covers (Figures 7 & 8). A machine specific tab-lock design is also available for Jessup robotic cover handling systems used for fully automated bulk load/unload systems. Jessup cylindrical barrels retrofitted to your plating line can deliver 17% more production with no other machine changes compared to hex barrels. The example 60-inch-wide barrels fit an identical workspace anode. Run at 12 loads per hour (LPH), the Jessup barrel delivers 8.16 more cubic feet. At 20 hours per day, this equates to 163.2 more cubic feet. If this machine runs 240 days per year, the difference is an incredible 39,168 cubic feet more production delivered on an annual basis by installing Jessup barrels! Jessup barrels are also available with center partitions, enabling large machines to process smaller lot sizes. This feature assures optimum machine utilization and maintains critical workload separation when combined with divided load/unload systems. PC over-the-top controls track, record, and export separate data for part numbers run simultaneously to a customer data highway for paperless quality control management and reporting. Partitioned barrels add small lot flexibility to large capacity machines. 8) The Jessup single-point set-down superstructure design incorporates 589
