High-Efficiency 48 Cavity PET Preform Mould Features
High-Precision Mold Manufacturing Process, Laying a Solid Foundation for Product Quality
Adopting industry-leading high-precision mold manufacturing processes, we integrate core technologies such as CNC precision milling, EDM, and WEDM. Combined with high-precision testing equipment including Coordinate Measuring Machines and laser interferometers, we achieve micron-level machining precision control for mold cavities, cores, and other key components. Precise mold processing not only ensures that key indicators of PET preforms—such as mouth size, wall thickness uniformity, and weight deviation—meet the top industry standards, but also guarantees the dimensional consistency of each preform during mass production. It fundamentally avoids quality issues such as mouth deformation and uneven bottle wall thickness in the subsequent blow molding process, fully meeting the high-quality and high-consistency production requirements of PET preforms in fields such as food, beverage, and pharmaceutical packaging.

Wear-Resistant & Premium Base Material, Extended Mold Service Life
Key mold components adopt internationally sourced high-grade mold steel. After precision heat treatments including vacuum quenching, cryogenic treatment and nitriding, the surface hardness reaches HRC52–58. Combined with premium Oerlikon Balzers coating, the mold delivers greatly enhanced wear resistance, corrosion resistance and demolding performance.
It withstands long-term high-speed continuous production, effectively resisting melt erosion and thermal shock. The mold is resistant to abrasion, galling and oxidation, maintaining stable durability under high-output working conditions and significantly reducing the full-lifecycle maintenance cost.

Efficient Rapid Cooling System to Boost Productivity
Optimized internal circulating cooling water channels ensure uniform heat dissipation and high heat exchange efficiency, enabling fast and even temperature reduction of PET preforms.
Efficient cooling directly shortens the molding cycle, allowing preforms in all cavities to reach a glassy state synchronously. It improves overall line output efficiency, stabilizes internal stress of preforms, guarantees dimensional and appearance quality, and provides reliable support for subsequent high-speed blow molding.

Flexible Custom Mold Design for Diverse Application Needs
We support full-process customized development. Mold solutions can be flexibly adjusted according to bottle design drawings, neck specifications (PCO 1810/1881, 26/22, 30/25 etc.), production capacity requirements and injection molding machine configurations.
The modular structure allows quick configuration changes, covering multi-cavity layouts from 48 to 144 cavities. It perfectly adapts to PET preform production of various capacities and shapes, and is compatible with high-speed injection molding systems of international brands such as Husky, Netstal and SACMI.

Optimized Balanced Runner System Ensures Stable Molding
The hot runner system adopts professional simulation analysis combined with physical verification to achieve thermal balance and stroke balance, broadening the injection molding process window.
The runner design ensures uniform, stable and synchronous melt filling, effectively avoiding material shortage, sink marks, uneven cooling and neck defects. It keeps consistent molding quality for every shot of preforms and improves yield rate as well as production stability.
