Along with the increasing demand for PET container, the requirement of PET preform has accordingly become more and more, which leads many investors to set foot on the PET preform production field. To meet the different requirements for the PET preform from different customers, Mega has successfully developed advanced hot runner preform mold from 1 cavity to 48 cavities for standard neck PET. Its wide utilization and reliable property with the economic investment, the shortest production startup time and the lowest maintenance cost make PET preform mold be most popular among preform manufacturers. Now we do have 2 series preform tool designs, one of series adopts rectifying system for preform’s wall thickness, and another series is standard structure.

- Valve-Gate Sealing System -- Gate-free Preform
Our Preform Injection Mould adopts special Valve-Gate Sealing System to produce gate-free PET preform, which can save much labor and material cost, also reduce the mold's wear & tear extent for customer.
- Hot Runner System
Our Preform Injection Mould adopts specially designed Pin-Valve type Hot Runner System to achieve ideal and prompt heating effect for preform production. Moreover, such hot runner system reduces mold's each part's wear & tear and maintenance cost, and also saves 10~15%'s electricity.
Our Preform Injection Mould adopts double Heating system to ensure perfect heating effect and reliable quality control. The Heater Unit is used to heat the hot runner plate with long service life and powerful heating capacity. The Heating Ring System is used to ensure the mold nozzle's constant heating temperature.
- Professional PET preform design to make imagination into reality
Based on the years' of experience and integration with most advanced mold technology we can design preform with both standard and non-standard neck/shape/volume for water bottle, CSD bottle and oil bottle with perfect bottle blowing performance as per customer's bottle requirement.
- Long Service Life: Over 2.5 Million Shots
Our PET Preform injection Mould enjoys a service life over 2.5 million shots, based on our years' design/manufacture experience, mold making know-how, adoption of CNC machines.
- Cooling System: Short Cycle Time & Perfect Preform Quality
In each inner mould part, there is well-designed cooling system with perfect cooling effect and abundant strength.
- Low Preform Eccentricity: Low Preform Eccentricity Away
