The 72-Cavity Preform Mold(Mould) is a solid, no-nonsense choice when you need to crank out PET bottle preforms at scale. It's built for the kind of high-volume work you see in beverage plants, food packaging lines, cosmetics bottling, and similar setups—where steady output and reliable quality matter more than anything flashy.
What makes it stand out
- High Productivity: With 72 cavities working together, you're getting 72 preforms every cycle. That adds up fast—higher daily totals, fewer machines running, and the ability to knock out big orders without scrambling for extra shifts or overtime.
- Cost-Effective Approach: The upfront price feels reasonable once you factor in how long it lasts and how little waste it produces. Tight molding means you're not throwing away as much PET resin, which keeps material costs down and helps with greener operations over time.
- Built to Last: We use P20 steel for the main body because it holds up under pressure, and S136 for the cores and cavities to fight off wear and corrosion from everyday production moisture or cleaning. It handles nonstop runs without losing its edge.
Key Features in Practice
- Premium Materials: P20 gives the structure real strength, S136 on the working surfaces adds that extra toughness and rust resistance—practical for shops where things get humid or chemicals are around.
- Precision Work: Everything is machined to hold ±0.1mm tolerances, so your preforms stay consistent in size, weight (we can customize the grammage), and surface finish. Most come out ready to go, with hardly any post-mold cleanup needed.
- Cooling That Works: The channels are laid out smartly so heat pulls away evenly and quickly from all 72 spots. Shorter cycles, fewer warped or uneven pieces, and quality that doesn't drift shot to shot.
- Modular and Flexible: When something needs attention, you can swap or service individual parts without tearing the whole thing apart—downtime stays short. It also lets you adjust for different neck finishes or preform styles if your product mix changes.
This mold keeps things running smoothly for high-output PET preform production, and it's flexible enough to match what your line actually needs. At Qihong, we put real focus into making molds that perform reliably year after year. If you're looking at specific grammage, neck types, runner preferences (cold or hot), or other tweaks, just get in touch—we handle customs all the time.
