Many machines require cooling water to keep the hydraulic fluid from overheating. Using VFD technology can reduce the heat generated in the first place, so external cooling is not needed, reducing cooling system demand and cost per shift translating to cost per part produced. Using VFD technology can reduce maintenance costs. Turning the motor off between cycles reduces wear & tear on motors, bearings, fans, hydraulic & process pumps, and many other moving parts. The increased component lifespan reduces replacement part costs as well as labor costs. Increased component lifespan expressed in Mean Time Between Failures (MTBF) also reduces unplanned downtime. This reduces the maintenance cost burden in every part produced. Using VFD technology can improve safety. The ability to turn the motor off between cycles reducing employee exposure to crush hazard during the loading and unloading of the trim press. Exposure to blades, spindles and other difficult to guard hazards can be reduced. Reduced noise between cycles contributes to a lower aggregate decibel level, especially when the VFD are installed on several machines. Lower background noise allows easier worker communication improving safety, and can reduce fatigue. Variable frequency drives are highly reliable components that should last the life of the trim press or other equipment. They are field install- able with minimum downtime. They provide additional ability to optimize for specific tasks. Adding variable frequency drives may qualify for energy and tax credits. We work with energy companies to provide accurate data to include in your energy credit application and also tax professionals to provide accurate data to include in your tax credit documentation. Whether you are considering new machinery, rebuilding worn machinery, or even currently operational machinery, using VFD technology has the capacity to add to your bottom line in many different ways. 53 CONVENTIONAL TRIM PRESS VS TRIM PRESS WITH VFD
