Preventive + Maintenance = Quality

He adds that the best course of action is to make a PM program routine, rather than a once or twice a year occurrence. “The program must be continual, resulting in the greatest long-term productivity from the [equipment].”

How comprehensive to make the PM program is also a consideration. Hart explains, “[The advantages] depend on the equipment, the material, and the process. And, it depends on what is meant by ‘comprehensive.’” She says that if “comprehensive” implies constant inspection, lengthy periods of downtime, and frequent replacement of parts, then that kind of program sounds like a disadvantage. She adds that maintenance to that extent also may be an indicator that an equipment upgrade is in order. “Preventive maintenance is helpful, but start with a well-designed, robustly built machine. The best splicers are those that follow the ‘KIS’ (keep it simple) principle. We have machines in operation for over 30 years. If you have a machine that’s built to last, then frankly, you shouldn’t need an exhaustive or costly PM program,” says Hart.
