We offer a wide range of customized PET preform mold solutions, covering the entire process from preform design and injection molding to final shaping. By optimizing preform structures to meet specific product needs, we enable the production of lighter, more refined bottle shapes with reduced material usage. This helps our clients lower manufacturing costs and enhance product competitiveness.

Delivering High-Quality Preform Molds

Durable and high precision

The preform mold ensures the coaxiality of the molded parts, the eccentricity is ≤0.1mm, the preform weight tolerance is ±0.2g, and the cavity and core are interchangeable. It has an efficient cooling system, the water circuit is sealed reliably without leakage, and the water and oil spacers are made of corrosion-resistant materials to ensure stable and durable mold performance.

Main Structure of Preform Mold

Better structure

Mold material

The molding parts (mold core, mold base, mold cavity, screw nozzle) are all made of FS136 high-strength anti-corrosion steel, the part hardness HRC is greater than 45°, the contact surface of the sliding parts (sliders, push plates, ejectors) is self-lubricating alloy copper material, DuPont insulation cap and Ambrox beryllium copper nozzle.

Hot runner

The hot runner is reasonably designed to ensure uniform flow of glue at each injection point. The embedded heating tube is used to heat the injection point to ensure that the temperature of each injection point is balanced and consistent. The material is filled into each cavity at the same time to form a more balanced runner.

Cold mold design

Optimized cooling system ensures fast cooling.Shorten cycle time and improve efficiency.Optimized exhaust system and stable demoulding structure，It can effectively remove gas during the injection molding process, prevent defects such as bubbles and shrinkage marks, and improve the surface finish and molding accuracy of the bottle embryo.
