Precision Engineering of 4 Cavity 3-Gallon Preform Mold
Manufacturing excellence begins with the right tooling, and the 4 Cavity 3-Gallon Preform Mold embodies precision engineering at its finest. Designed for converters who need consistent heavy-wall preforms for large water-cooler bottles, this mold delivers four identical 3-gallon preforms every cycle. The 4 Cavity 3-Gallon Preform Mold is machined from premium H-13 tool steel, through-hardened to 48-52 HRC, ensuring long life under high-pressure PET injection.
Every detail of the 4 Cavity 3-Gallon Preform Mold is optimized for uniform wall thickness and minimal gate vestige. A balanced hot-runner manifold keeps melt temperature identical in all four drops, eliminating weight variation. Interchangeable neck-ring inserts allow 38 mm, 45 mm, or 55 mm finishes without removing the 4 Cavity 3-Gallon Preform Mold from the press. Quick-change cores and cavities mean color or weight changes take less than 30 minutes, a critical advantage when the 4 Cavity 3-Gallon Preform Mold is running 24/7 to meet peak-season demand.
Cooling efficiency sets the 4 Cavity 3-Gallon Preform Mold apart. Conformal cooling channels follow the preform profile, cutting cycle time to 28 seconds on a 350-ton press while holding ±0.05 g weight tolerance. Users report that the 4 Cavity 3-Gallon Preform Mold produces over 1.2 million shots before the first major service, thanks to diamond-polished surfaces and DLC-coated core pins that reduce PET sticking.
Maintenance is simplified by the 4 Cavity 3-Gallon Preform Mold’s split-cavity design. Technicians can swap individual cavities without disassembling the entire stack, keeping downtime low. Optional in-mold vision inspection flags short-shots or flash in real time, protecting downstream blow molding from costly interruptions.
For converters seeking to scale production, the 4 Cavity 3-Gallon Preform Mold offers a clear ROI. A single press equipped with the 4 Cavity 3-Gallon Preform Mold can output 12,000 preforms per day, replacing two older 2-cavity tools while using 18 % less energy. The robust construction and intelligent layout of the 4 Cavity 3-Gallon Preform Mold make it the cornerstone of any high-volume 3-gallon bottle program.
