Press racks are considered a consumable so time to time replacement should be expected. When you notice a hairline crack, generally during cleaning, the rack should be replaced immediately. Continued operation with a cracked rack will eventually cause damage to the press bags. Goodnature recommends stocking 8 press racks at all times to ensure no loss of production time.
Proper installation of replacement racks is critical to rack longevity. When installing replacement racks be certain to snug the rack ties at the top of the press area and leave the rack ties at the bottom loose. Over tightening of the bottom rack ties will cause too much stress on the both the tie and the rack, leading to premature failure. This will be most noticeable in the closed position.
