A 16 Cavities Preform Mold hits a sweet spot between output and affordability, suitable for growing converters.
Optimized Output for Mid-Volume Producers
The 16 Cavities Preform Mold enables annual outputs in the tens of millions while fitting into a medium-tonnage injection machine (200-300 tons). This combination of mold and press represents an optimal capital efficiency point, providing low cost-per-preform without the complexity of ultra-high cavitation.
Radial 16-Fold Symmetry
We design the cavity layout of a 16 Cavities Preform Mold with perfect circular symmetry around the central sprue. This radial arrangement ensures that the melt travel distance is identical for every cavity with zero geometrical bias, resulting in weight variation typically below 0.08 grams.
Easy Access for Daily Maintenance
With 16 cavities, the 16 Cavities Preform Mold offers generous space between each cavity insert. This open access allows operators to easily clean vent channels, inspect gate tips, and apply lubrication, all while the mold is still in the press. Such accessibility minimizes unplanned downtime and extends mold life.
Stable Process for Non-CRT Resins
The moderate cavitation of a 16 Cavities Preform Mold is very forgiving when running post-consumer or off-spec resins. The process window is wide, and any viscosity shift can be immediately compensated by a slight temperature adjustment, making this mold ideal for operations that want to incorporate high percentages of recycled content.
DEMARK Injection System - Your Shortcut to a Smarter PET Line. We exist to make your packaging production more profitable and less dependent on labor. By combining our proprietary two-stage PET injection machines, ultra-high-cavitation molds (up to 144 cavities), and fully integrated automation, DEMARK delivers complete manufacturing cells that slash cycle times, minimize scrap, and run unattended for extended periods. It's the fastest path from resin to finished preform.
