When beverage brands increase cooler-jug volumes, molders turn to the 4 Cavity 3-Gallon Preform Mold to double throughput without doubling footprint. By expanding from two to four cavities, the 4 Cavity 3-Gallon Preform Mold transforms a 350-ton press into a 3-gallon powerhouse, cycling every 28 seconds and yielding 514 preforms per hour per cavity.
The productivity story begins with balanced filling. The 4 Cavity 3-Gallon Preform Mold uses a naturally balanced hot-runner layout, so each cavity receives identical melt pressure and temperature. This eliminates the need for operator tweaking, letting the 4 Cavity 3-Gallon Preform Mold run lights-out through three shifts. A servo-driven valve gate closes each nozzle precisely, reducing stringing and saving 1.2 % PET resin per shot.
Cycle-time savings compound quickly. Compared with a legacy 2-cavity tool, the 4 Cavity 3-Gallon Preform Mold cuts average cycle time by 12 % and halves the number of presses needed for a 50,000-preform day. Energy monitoring shows the 4 Cavity 3-Gallon Preform Mold consumes 0.42 kWh per 100 preforms versus 0.55 kWh for older designs, thanks to optimized cooling circuits and reduced clamp tonnage.
Downstream harmony is another benefit. Because all four preforms leave the 4 Cavity 3-Gallon Preform Mold at the same temperature and weight, blow molder adjustments are minimal. Reheat stretch-blow machines index faster, and scrap rates drop below 0.5 %. One Midwest water bottler reported that switching to the 4 Cavity 3-Gallon Preform Mold lifted overall line OEE from 67 % to 82 % within six weeks.
Space and labor savings seal the deal. Replacing two aging 2-cavity tools with one 4 Cavity 3-Gallon Preform Mold freed 60 m² of floor space and eliminated one full-time operator position. The mold’s integrated lifting eyes and quick-connect water lines allow changeover in under 45 minutes, so the same press can run the 4 Cavity 3-Gallon Preform Mold for 3-gallon bottles and then switch to 5-gallon handles for the next shift.
For plants under pressure to deliver more with less, the 4 Cavity 3-Gallon Preform Mold is the definitive lever for profitable growth.
