LEIZHEN is a specialized manufacturer dedicated to the design and production of high‑precision PET preform molds. With a sharp focus on quality, accuracy, and reliability, we serve the global packaging industry by delivering mold solutions that produce consistent, defect‑free preforms for a wide range of bottle applications – from small water bottles to large beverage containers.

Why Precision Matters in Preform Molds

The preform determines the final quality of the blown bottle. Any deviation in wall thickness, neck finish, or dimensional accuracy leads to rejected bottles, material waste, and production downtime. LEIZHEN’s high‑precision preform molds are engineered to eliminate these risks. Using advanced CNC machining and strict quality control, each cavity delivers identical geometry, smooth surfaces, and perfect neck completion – ensuring every preform stretches uniformly during blow molding.

Advanced Manufacturing & Quality Control

• Ultra‑precision CNC Machining – Our molds are machined on high‑end equipment to achieve micron‑level tolerances, ensuring perfect cavity alignment and consistent preform weight distribution.

• Premium Mold Materials – We use corrosion‑resistant stainless steel and hardened tool steel for exceptional durability and long production life, even under high‑cavity, high‑cycle operations.

• Hot Runner Technology – Integrated hot runner systems provide precise melt temperature control, reduced pressure loss, and faster cycle times with minimal material waste.

• Optimized Cooling Design – Efficient cooling channels shorten cycle times while maintaining dimensional stability, boosting your hourly output without compromising quality.

Product Range & Customization

LEIZHEN offers complete customization for preform molds to match your specific bottle design, neck finish (PCO, 1881, ALCO, etc.), weight, and capacity requirements – from 150ml to 20L+. Whether you need 2‑cavity molds for small‑scale production or 72‑cavity high‑output systems for mass manufacturing, we deliver solutions tailored to your blow molding line (semi‑automatic or fully automatic).

One‑stop Service from Design to Trial Production

We provide a seamless experience: mold design consultation, simulation analysis, precision manufacturing, assembly, and trial production at our facility. Before delivery, every mold undergoes rigorous testing to guarantee preform quality and operational reliability. Our technical team also offers on‑site commissioning support and after‑sales service to keep your production running smoothly.

Global Partnership & Factory Direct Supply

As a factory‑direct supplier, LEIZHEN offers competitive pricing without compromising on precision or service life. We ship worldwide and have helped bottle manufacturers across Asia, the Middle East, Africa, Europe, and the Americas build efficient, high‑quality preform production lines.
